From UPSC perspective, the following things are important :
Prelims level : WIS, WIBS
Mains level : Applications of Lithium ion battery
- The Johns Hopkins Applied Physics Laboratory has developed a Lithium-ion battery that will not catch fire.
WiS and WiBS
- Lithium-ion batteries are vulnerable to fire and explosion, which often happens without warning.
- This is because they are built with flammable and combustible materials.
- The researchers has announced the discovery of a new class of “water-in-salt” and “water-in-bisalt” electrolytes—referred to as WiS and WiBS.
- The new class of electrolytes, when incorporated in a polymer matrix, reduces water activity and elevates the battery’s energy capabilities and life cycle.
- This rids it of the flammable, toxic, and highly reactive solvents present in current Li-ion batteries. It’s a safe, powerful alternative.
Why it matters
- Li-ion batteries have emerged as the energy storage vehicle of choice for portable electronics, electric vehicles, and grid storage.
- These safety advancements, the university release, mark a significant step forward in transforming the way Li-ion batteries are manufactured and used in electronic devices.
- Li-ion batteries are already a constant presence in our daily lives, from our phones to our cars, and continuing to improve their safety is paramount to further advancing energy storage technology.
