New tech to prevent Li-ion battery fires

Materials researchers from Nanyang Technological University Singapore have actually discovered a method to avoid internal short-circuits, the primary reason for fires in Li-ion batteries.

Billions of Li-ion batteries are produced each year for usage in smart phones, laptop computers, individual mobile phones, and the big battery packs of electrical cars and airplane.

This worldwide battery need is set to grow, with electrical lorries alone needing as much as 2,700 GWh worth of Li-ion batteries a year by 2030, comparable to some 225 billion smart phone batteries.

Even with an approximated failure rate of less than one-in-a-million, in 2020 there were 26 power-assisted bike (PAB) fires and 42 cases of individual movement gadget fires in Singapore.

In many Li-ion battery fires, the cause is because of an accumulation of lithium deposits referred to as dendrites (small wire-like tendrils) that cross the separator in between the favorable (cathode) and unfavorable (anode) electrodes of the battery when it is being charged, triggering a short-circuit causing an unchecked chemical fire.

To avoid such battery fires, NTU researchers developed a patent-pending “anti-short layer” that can be quickly included inside a Li-ion battery, avoiding any future short-circuits from taking place throughout the charging procedure.

This idea belongs to including a piece of cheese to a hamburger’s meat patty in between the buns, therefore the brand-new “anti-short layer” can be quickly embraced in existing battery production.
