The primary reason hoverboards have become public enemy #1 in recent times is due to their unfortunate tendency to catch fire and explode due to their lithium-ion batteries overheating.
But a new lithium-ion battery developed by scientists in the US could put an end to such dramas. Researchers at Stanford University have made the world’s first lithium-ion battery that shuts off before it overheats, then restarts immediately when its temperature has cooled.
Conventional lithium-ion batteries comprise a pair of electrodes and a liquid or gel electrolyte that carries charged particles between them. However, if the battery’s temperature reaches around 150 degrees Celsius (300 degrees Fahrenheit) as a result of a defect or overcharging, the electrolyte can catch fire and trigger an explosion, as we’ve seen in many sad cases.
