The Future of Lithium-Ion Battery Applications

The Future of Lithium-Ion Battery Applications

Lithium-ion battery is one of the most renowned batteries in today’s world.These are a type of rechargeable battery where lithium is a major component of this battery. 

They have been in the market for so long yet the advancements that these batteries bring forth have never stopped. The manufacturers are thriving for bringing an updated and better version of these batteries so that their products can be enhanced which is necessary for the market and the industries that become a part of it.


Lithium-ion batteries have excellent features which increase their applications and therefore the future that these batteries hold is very promising as their credibility has remained a constant throughout their years in the market. A new product known as a lithium-ion battery was announced in 1991. This announcement was shortly after the product recall of phones utilizing the lithium/MoS2 batteries due to a vent with flame resulting in the user getting injured. It is constantly tried by leading companies to make a lithium metal battery with the positive electrode being manganese dioxide, but this system also had safety problems. These hazards are familiar to the author due to his work at Energizer Research Laboratory at the same time as the Li/MnO2 systems.

Cells Under Test

Indications of dendritic lithium shorting (during charge, it is seen as negative voltage spikes) will be shown by the cells that are under test, and the unpredictable and occasional cell explosions that followed them. Lithium metal technology is interesting because of its cells being of high energy density and specific energy.

Further Improvements in Lithium

Lithium's low atomic weight and high cell potential were the reason for the enhancement over the previous aqueous systems in comparison to all of the other already investigated negative electrode materials. There have been notable investigations of the other lithium batteries such as, the Li/NbSe3 system and the Li/TiS2 system. Safety concerns were plagued which discovered that the lithium negative electrode was not only dangerous but the electrolyte which was made up of LiClO4 salt dissolved in primary dioxolane (an ether solvent), was dangerous too as it was shocking sensitive and strong enough shock conditions, it is liable to explode.

Limitations in the Cycle Life of Lithium

Lithium electrodes' poor recycling efficiency makes the cycle life extremely limited. An excess of lithium metal was utilized in most of the studies in a cell for giving enhanced efficiency but where there was the usage of excess lithium, there was a rapid drop in capacity with each cycle.

Learnings Through the Lithium Ion Battery Development Process

This unsuccessful work with lithium resulted in significant learning about the requirements of the material and process. In the electrode materials and electrolyte, there was much more sense of the secondary cells to the impurities like water. As compared to the processing methods of the primary batteries, the processing methods were different here. It was good work for the development of the Li-ion battery to the present systems’ excellent state. The work in the lithium metal batteries was reviewed in this paper and it resulted in the lithium-ion system’s invention and development. Finally, there are discussions on the development, existence, and shortcomings of this battery, the present system, and the enhancements that will predict the lithium-ion battery’s future capabilities.

New Systems Development

Completely new systems like metal anodes, other insertion systems like liquid or gaseous cathode systems, and sodium-ion batteries are developed that won't be considered, thus the reader should know that a potential is possessed by the different rechargeable battery concepts to displace at least some applications of the lithium-ion battery because of the lower cost, better safety, higher energy or power.

Early Studies on Lithium Ion Batteries

There were various studies in the past related to the 199. In the late 1970s, Armand first formulated the idea of a battery in which there was a reversible movement of the lithium-ion between the negative and positive electrodes, by utilizing the intercalation materials having different potentials for the two electrodes, and is usually known as a rocking chair battery due to the back and forward flow of the lithium ions between the 2 electrodes.

Implementation with The Lithiated Tungsten Dioxide

Scrosati and Lazzari quickly took up the idea and implemented it with a titanium disulfide electrode and a lithiated tungsten dioxide electrode. 0.8-2.1 volts was the only potential range and high molecular weights were featured by both of the electrodes, but the establishment of the main principle was done when the cell cycled for almost 60 cycles however the charge voltage was limited to around 2.2 V, and discharge to around 1.6 V.

The Discovery of Goodenough Laboratory

The Goodenough laboratory made a seminal discovery of the capability of the NaFeO2 structure’s family of lithiated transition metal oxides to reversibly deintercalation and intercalate the lithium ions at comparatively high potentials (however there was a limited voltage for preventing the electrolyte oxidation). Cobalt and Nickel and mixtures of these with Fe, Al, Mn, etc. had the capability and later adoption of the patented material (LiCoO2) to form lithium-ion battery’s active positive material. Then after some time, MnO2’s new form was discovered by the J. C. Hunter of the Eveready Laboratories, designated as the λ form, with a spinel structure, made from LiMn2O4 (spinel form), which can be reversibly reduced and oxidized at the high potential in a nonaqueous electrolyte like that of LiCoO2 with the same capacity. Later, this material was selected for various higher-rate batteries for commercial applications.

Discovery of Negative Electrodes

Compared to the discovery of positive electrode materials, discovering the appropriate negative electrode materials was more complicated. It can be seen in the early work on the carbonaceous materials and graphene that the intercalation of lithium ions is possible, the co-intercalation of the solvent molecules complicated the process, during which the carbon structure’s disruption and the solvent reduction took place. Yazami of the University of Grenoble and Basu of Bell Laboratories didn’t take early work on the graphite electrodes, like early patents into account and that’s why it could have failed in the practical batteries.

Important Findings

Dahn, Von Sacken, and Fong had a significant finding that as compared to graphite, petroleum coke was way better for resistance towards solvent reduction and co-intercalation, whereas the resistance on both petroleum coke and graphite was significantly enhanced by ethylene carbonate’s addition to PC. Although, the advantages of lower temperature carbons like petroleum coke in a seminal patent have been already described by Yoshino, it has led to the identification of Yoshino as the lithium-ion battery’s true inventor.

Combination of Temperatures

In this patent, a combination of lower temperature cokes (calcination temperature of 800-1600°C and formula which involves the ρ X-ray and Lc parameters) and a slightly modified LiCoO2 material from that suggested by Goodenough. Commercial cokes were utilized which were treated with heat at almost 1300 degrees Celsius, and thus were relatable to those cokes that were utilized by Yoshino et al., and the cokes that were cycled at a low rate, had half of the reversible capacities as compared to the reversible capacities of the graphite (1.0 for graphite, 0.5 for coke, and x in LixC6). Pure starting materials have been utilized by Yoshino et al., mostly instead of petroleum. The coke’s purity was way more as compared to the coke’s purity.

Differences in the Studies

The salt utilized in the electrolytes was different in both studies. LiAsF6 is this kind of salt that various researchers considered it as one of the best electrolyte salts for secondary lithium metal batteries, whereas LIPF6, LiBF4, and LiClO4 were used by Yoshino et al., and they were commonly utilized for primary lithium metal batteries.

Information Regarding Numerous Binders

Various elastomers, polyvinylidene fluoride, and polymethylmethacrylate are included in the various binders that are studied for batteries. However, only ethylene propylene diene monomer (EPDM) was extensively used for the secondary lithium metal batteries. Instead of a metal oxide, lithium was used to test the carbonaceous positive electrode. Thus, the extreme corrosion of an aluminum positive electrode carrier was not observed by them with the LiAsF6 electrolyte. Such corrosion was observed by the author in the full-cell experiments later with (Cu-C/LiCoO2-Al) cells that in full cells, would have obviated usage of that salt.

Utilization of Separators

Microporous polypropylene separators were used whereas instead of polypropylene, a microporous polyolefin separator was frequently used by Yoshino et al. and they also recommended a microporous polyolefin separator. Dr. Yoshino's internet profile has been published by Asahi Kasei, and his work on lithium-ion batteries includes a lot of his early work was also included in that profile. Later, a joint venture was made by Asahi Kasei to make A&T Battery Corp. for making Li-ion batteries. Now, A&T operates within Toshiba as a subsidiary company.

Superior Characteristics of Lithium-ion Batteries

Yoshino et al. laid out the lithium-ion battery's main elements, however, various studies are present to develop a commercial battery with excellent characteristics to the newly discovered nickel metal hydride and nickel-cadmium batteries. There was an urgent need as these earlier batteries were very less, specifically the environmental problems, poor charge retention issues, low specific energy, and memory effect, with the cadmium system. There was rapid development in the electronics industry, especially in the famous 3Cs (computations, communication, and cameras).

Present-Day Lithium Ion Batteries

Originally it was not as complicated as it is now for lithium-ion batteries to work and survive in today’s world. A lot of additional markets have been opened up for the small devices so that the bigger industries are not affected including toys, lighting of all kinds, vaporizers and e-cigarettes, a few medical devices, and many others as well. There was a discovery about the lithium-ion battery packs where 18650, 26700, and 26650 sizes were designed so that higher power can be operated than the one that already originated. This enhances the product value and enables it to reach a greater audience.

High-Energy Cells

The incorporation of high-energy cells has fairly done great business in the market as they comprise almost 3.4 Ah in the case of 18650 cells. It has been made sure that the high-power cells have to sacrifice the capacity to obtain 20A so that a better and higher continuous discharge capability is obtained in the 18650 cell size. However, there are a few cells that claim that they have a 2.5 Ah capacity but it is rather difficult to keep up with this high of a capacity during the cycling process. The studies that have been carried out in this regard show a clear picture of how important it is to have multiple tabs and tab placements.

Development of Ceramic Coatings

The development of ceramic coatings has brought a new advancements in the market for rechargeable batteries. The ceramic coatings are performed on either a separator or a positive electrode which has shown very beneficial effects in terms of prevention of the internal short-circuiting which may happen during the process of cycling as a lot of metal particles are present on the electrode surfaces. These said particles are rather very small in size and have airborne properties as most of the time they result in mechanical slitting of the electrodes. The separator ranges from 12 to 25 μm in thickness which is why the short-circuiting takes place and it must be acknowledged that the separator must be as thin as 2 μm and not more.

Additional Advantages of Ceramic Coatings for Lithium-ion Batteries

A few other additional advantages of coating these separators include a reduction in the shrinkage of the separator at the shutdown temperatures which is the shutting down of current due to melting of the separator which is not possible in the case of direct contact between the cathode and anode. Another one includes better cycling as it promotes safety and keeps the circuit from any safety hazard that can come along and the last one is improved electrolyte wetting as it is there in the first place due to the wet inorganic oxide ceramic phase. The complex coatings are becoming normal as well so that the penetration strength can be increased of the coating.

Addition of Silicon to Lithium Battery

It is difficult to get hold of the battery industry but over the years it has been made evident that silicon is now being incorporated in small amounts into the negative electrode of lithium-ion batteries which are made out of graphite. This addition increases the high specific capacity of lithium silicon alloy anodes which shows us that despite the addition of a very small content of silicon, the specific capacity of the electrode gets affected at such a higher rate. After this outcome, a lot of researchers are still in progress to find a way through which small amounts of silicon can be brought to the surface of graphite particles, and then the graphite suppliers can carry out their proprietary process.

For example, materials having an energy of 400 to 500 mAh/g is very commonly available and are being used for premium lithium-ion batteries which provide a capacity of over 3 Ah in the 18650 cells. Though these cells are a little more expensive than the other ones they have a high cycle life and a higher capacity.

Present-Day Cathode Materials

The present-day cathode materials which are commonly used are LiCoO2 and LiMn2O4. There is one material that is still in the process of development generally known as NMC.

Deficiencies of Present Lithium Ion Batteries and Potential Improvements

There are a few deficiencies that the present-day lithium-ion batteries comprise but with suitable conditions and the required environment these same batteries can be transformed into superior lithium-ion batteries that would open new roads toward the advanced stages of applications that would be extremely helpful to promote the market growth for these present-day lithium-ion batteries. Further factors that can enhance productivity and bring advancements in the future life of present-day lithium-ion batteries will be brought to light.

Market Pull in Li-ion Batteries

The market pull is acting with a great deal of involvement in the case of lithium-ion battery manufacturers as all the companies that are using these batteries are constantly asking for an updated version of these batteries which will have an increased capacity and energy and all the necessary measures are being taken so that the advancements can be introduced in the market and renewable energy sources including wind and solar can be used to replace natural gas fuels and coal for serving the purpose of energy production. However, the cost element holds a great deal of importance as well but keeping these things in consideration, the steps towards betterment are being taken accordingly.

Lithium-ion Batteries for the Automotive Industry

The major goal of auto manufacturers and the Us Department of Energy is equivalent to $125 per kWh for a single battery pack whereas well-known auto manufacturer comprises a 60 to 100 kWh battery. All these estimates are being in consideration so that the measures that are needed to be taken will progress according to the facts and figures that build up the credibility of the product which is a basic to be maintained because a buyer always seeks credibility before using the product firsthand.

Lithium-ion Batteries for Energy Storage

Energy storage is the second major production area of lithium-ion batteries while being stabilized in terms of storage for the electric grid. This is one of the major needs of the batteries that the governments are also asking to bring in after the updated version of the lithium-ion batteries. The incorporation of better energy schemes is very important and the sooner they are brought into work, the better it would be for the batteries to progress and flourish in a very positive way which will ultimately increase the number of applications that the lithium-ion batteries are already dealing with.

Involvement of Lithium-ion Batteries in Market

Lithium-ion batteries have considerably a longer cycle life and calendar life with all the charging and discharging regimes that it constantly brings to the market. With every passing day and upgrade, the needs are increasing too but there are always possible ways to meet up the demands of the consumer, and when those needs are met that is when the production and market value of the product increases too. It is important to keep up with the advancements that are coming up in the industrial world as only then the necessary work will be carried out which will enhance the value of the product.


Lithium-ion batteries being one of the most promising types of rechargeable batteries have truly emerged as a star in the market of batteries as they have showcased their excellent features throughout their stay in the market. In the future as well, the manufacturers of lithium-ion batteries aim to take these further with bring all the necessary advancements in their products which will ultimately increase their reach and applications in the market.
