A safer alternative of lithium-ion batteries developed.

Scientists have developed a safer alternative to fire-prone lithium-ion batteries, Li-ion batteries are currently is used in many household applications such as Mobile Phone, Laptops etc.

Researchers at the U.S. Naval Research Laboratory (NRL) developed the nickel-zinc (Ni-Zn) batteries in which a three-dimensional(3D) Zn “sponge” replaces the powdered zinc anode, or positively charged electrode, traditionally used.

With 3D Zn, the battery provides an energy content and rechargeability that rival lithium-ion batteries while avoiding the safety issues that continue to plague lithium.

Zinc-based batteries are the go-to global battery for single-use applications, but are not considered rechargeable in practice due to their tendency to grow conductive whiskers (dendrites) inside the battery, which can grow long enough to cause short circuits.
