Scientists have announced Li-ion battery that ‘won’t catch fire.’
About:
Background: 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.
Recent development: Now, the Johns Hopkins Applied Physics Laboratory has developed a Lithium-ion battery that will not catch fire.
Significance: Li-ion batteries have emerged as the energy storage vehicle of choice for portable electronics, electric vehicles, and grid storage. These safety advancements mark a significant step forward in transforming the way Li-ion batteries are manufactured and used in electronic devices.
Working:
The 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’s a safe, powerful alternative.
