Materials scientists from Nanyang Technological University Singapore have found a way to prevent internal short-circuits, the main cause of fires in Li-ion batteries.
Billions of Li-ion batteries are produced annually for use in mobile phones, laptops, personal mobile devices, and the huge battery packs of electric vehicles and aircraft.
This global battery demand is set to grow, with electric vehicles alone requiring up to 2,700 GWh worth of Li-ion batteries a year by 2030, equivalent to some 225 billion mobile phone batteries.
Even with an estimated failure rate of less than one-in-a-million, in 2020 there were 26 power-assisted bicycle (PAB) fires and 42 cases of personal mobility device fires in Singapore.
