Supplies scientists from Nanyang Technological College Singapore have discovered a approach to stop inner short-circuits, the primary reason behind fires in Li-ion batteries.
Billions of Li-ion batteries are produced yearly to be used in cell phones, laptops, private cell units, and the large battery packs of electrical automobiles and plane.
This world battery demand is about to develop, with electrical automobiles alone requiring as much as 2,700 GWh value of Li-ion batteries a 12 months by 2030, equal to some 225 billion cell phone batteries.
Even with an estimated failure price of lower than one-in-a-million, in 2020 there have been 26 power-assisted bicycle (PAB) fires and 42 instances of private mobility machine fires in Singapore.

In most Li-ion battery fires, the trigger is because of a build-up of lithium deposits often known as dendrites (tiny wire-like tendrils) that cross the separator between the optimistic (cathode) and destructive (anode) electrodes of the battery when it’s being charged, inflicting a short-circuit resulting in an uncontrolled chemical hearth.
To stop such battery fires, NTU scientists invented a patent-pending “anti-short layer” that may be simply added inside a Li-ion battery, stopping any future short-circuits from occurring in the course of the charging course of.
This idea is akin to including a slice of cheese to a hamburger’s meat patty in between the buns, thus the brand new “anti-short layer” may be quickly adopted in present battery manufacturing.
