Lithium Ion Cell technology Current Affairs - 2020
The scientists at John Hopkins Applied Physics Laboratory, US, have developed Lithium-Ion batteries that can operate under extreme conditions like submersion, ballistic impact, cutting and heat. In simple lay man terms, they can operate even under fire!
The Lithium-Ion batteries that are commonly used in every household item starting from smartphones are susceptible to catastrophic fire and explosion. Because of this, many phones were banned from airlines and ships. The US Navy had prohibited the use of e-cigarettes on ships and submarines because of the danger the batteries possessed.
The Technology behind the battery
The scientists have used water-in-salt and water-in-bisalt electrolytes in the batteries. These electrolytes were incorporated in a polymer matrix to reduce water activity and elevate energy capabilities of the battery. This gives the batteries higher energies to withstand heat and pressure.

ISRO’s rocket sciences arm Vikram Sarabhai Space Centre (VSSC) has decided to transfer its own in-house lithium ion (Li ion) cell technology to successful Indian industries and start-ups on non-exclusive basis in automobiles for Rs. 1 crore. The initiative aims to accelerate development of indigenous electric vehicle (EV) industry and reduce dependence of imported lithium ion cell technology.
In this regard, VSSC has issued RFQ (request for quotation) inviting multiple qualified companies or start-ups to use its power storage technology to produce range of Li ion cells for many purposes, mainly EVs or electric vehicles. The transfer of ISRO’s technology will help in establishing production facilities in the country that can produce cells of varying size, capacity, energy density and power density catering to entire spectrum of power storage requirements of electric vehicles (EVs).
Presently, lithium-ion battery is the most dominant battery system finding applications for variety of societal needs including handy consumer electronics goods such as mobile phones, laptops, cameras and many other portable consumer gadgets apart from industrial applications and aerospace. Most of the current domestic demand is met by batteries imported from China, South Korea and Taiwan. The Li ion cell production initiative is part of Central Government’s plan to achieve 100% EVs in the country by 2030.
