Tech developed for Improved Lithium-ion Battery Performance

Researchers from IIT Guwahati have developed a technique to improve the performance of rechargeable lithium-ion batteries, which power most of the portable devices used today.

New Technology

The 2019 Nobel Prize in Chemistry was jointly awarded to Stanley Whittingham, John Goodenough and Akira Yoshino for work that led to the development of lithium-ion batteries.
These batteries are used in most mobile phones, smartphones, tablets, laptops and power banks, among other devices.
Today, most Electrical Vehicles (EV) use Li-ion batteries as well, but are slowly reaching their theoretical limits of being able to provide roughly up to 300-watt hour per kilogram of energy.
These batteries can also be used to store solar and wind power, which means that with their widespread use it may even be possible to live in a fuel free society.

Disadvantages

Li-ion batteries are susceptible to overheating and are prone to damage at high voltages since they are made with flammable and combustible materials.
Such batteries also start losing their capacity over time

Alternatives to Li-ion batteries

In January 2020, researchers from Australia claimed that they developed the world’s most efficient lithium-sulfur (Li-S) battery, capable of powering a smartphone for five continuous days
Li-S batteries are generally considered the successors of Li-ion batteries because of their lower cost of production, energy efficiency and improved safety.
Their cost of production is lower because sulfur is abundantly available.
