Billions of Li-ion batteries are produced each year for use in cell phones, laptops, personal mobile devices, and huge batteries in electric vehicles and airplanes.
In most Li-ion battery fires, the cause is due to a build-up of lithium deposits called dendrites (small, wire-like tendrils) that pass through the separator between the positive (cathode) and negative (anode) electrodes of the battery. battery when it charges, causing a short circuit leading to an uncontrolled chemical fire.
To prevent such battery fires, NTU scientists have invented a patent-pending “anti-shorting layer” that can be easily added inside a Li-ion battery, thus preventing any future short- circuit. circuit to occur during the charging process.
