RECENT ADVANCEMENTS IN LITHIUM BATTERY

In this assignment I am going to discuss the different properties and advancements in lithium batteries.
I have below listed the different aspects and along which the researches that have been done to improve the lithium battery output.

Future batteries, coming soon: charge in seconds, last months and power over the air

While electrical devices are becoming smart and even more advanced, they are still limited when it comes to power and battery.
The battery has not advanced in decades but we are on the verge of a power revolution.
Big technology companies, car companies and smartphone companies are well aware of the limitation of the currently

Nickel has high specific energy but poor stability whereas manganese forms a spinel structure to achieve low internal resistance but has a low specific energy. Therefore, the metals enhance each other’s strengths. The composition of the cathode is usually one-third nickel, one-third manganese, one-third cobalt. This lowers the raw material cost as it reduces the amount of cobalt used. Other combinations also exist, such as NCM, CMN, CNM, MNC and MCN in which the metal content is different from the ‘one-third’ formula.

Lithium Titanate Batteries
In these types of batteries, the graphite in the anode of a typical lithium-ion battery is replaced and the material is formed into a spinel structure. However, the cathode is graphite and so the architecture resembles that of a typical lithium-metal battery. It can be fast-charged and delivers a high discharge current. The cycle count is also higher than a regular lithium-ion battery. A lithium titanate battery is safe, has excellent low-temperature discharge characteristics, a wide temperature range and a long life span. However, it is expensive and has low specific energy.

LFP offers good electrochemical performance with low resistance. The key benefits of this type of battery include high current rating, long cycle life, good thermal stability, enhanced safety, long life span and tolerance. It is also less stressed than other lithium-ion batteries if kept at a high voltage for a prolonged time. However, it has a higher self-discharge and a lower voltage than other lithium-ion batteries and moderate specific energy. It has a flat voltage discharge curve but low capacity.

MY VIEW
• I think that there is much more advancements that have to be achieved to improve the efficiency of the Lithium batteries on which there are being researched by scientists around the world.
• Many multinational vehicle companies have invested huge amounts of money in the researches to improve the battery life.
• Today everyone owns the smart phone but the real drawback is the batteries which will solved by the different types of Lithium batteries that are coming up in our
