Researchers from Johns Hopkins Applied Physics Laboratory have developed a Lithium-ion battery that will not catch fire.
WiS and WiBS
- The research team has announced the discovery of a new class of “water-in-salt” and “water-in-bisalt” electrolytes—referred to as WiS and WiBS, respectively.
- This new class of electrolytes, when incorporated in a polymer matrix, reduces water activity and elevates the battery’s energy capabilities and life cycle while ridding it of the flammable, toxic, and highly reactive solvents present in current Li-ion batteries.
- It is a rechargeable battery that uses lithium ions as the primary component of its electrolyte
- They have emerged as the energy storage vehicle of choice for portable electronics, electric vehicles, and grid storage.
Significance of the discovery
- Li-ion batteries are vulnerable to fire and explosion, which often happens without warning.
- This is because they are built with flammable and combustible materials.
- These safety advancements mark a significant step forward in transforming the way Li-ion batteries are manufactured and used in electronic devices.
