There’s been a gradual stream of comparable, although remoted, incidents ever since. Nonetheless, regardless of the high-profile protection of batteries gone unsuitable, the overwhelming majority of Li-ion batteries are secure.
The chemical response that happens inside a lithium-ion cell is advanced, however as in any battery, there is a detrimental and a constructive electrode.
