Lithium-ion batteries, whether they are used in cars or electronic devices, can catch fire if they have been improperly manufactured or damaged, or if the software that operates the battery is not designed correctly.
Nearly all electric vehicles (EVs) currently on roads worldwide use lithium-ion, or Li-ion, batteries, for their high capacity and efficiency properties.
A Li-ion battery’s capacity and voltage is determined by the lithium-based metal used for its positive electrode, which releases electrons, and so the battery is usually named for its components.
There are three major types of Li-ion batteries used to power the world’s bestselling electric cars: NCM, in which the cathode is composed of lithium, nickel, cobalt and manganese; LFP, made up of lithium, iron and phosphate; and NCA, containing nickel, cobalt and aluminium.

Li-ion batteries comprise four main parts: the cathode and anode that store the lithium; the electrolyte that carries lithium ions between the anode and cathode; and the separator, a thin plastic filter that physically separates the anode and cathode, only allowing ions to pass through.
When discharging, lithium-ions move from the carbon-based anode (the negative...
