Panasonic Develops Battery That Won't Overheat
After the world was hit by the exploding laptop battery fiasco earlier this year, engineer at Panasonic have started to develop some new models of lithium-ion batteries that are not supposed to overheat, even in the case where a short circuit occurs.
The new battery includes a heat-resistive insulator inside the battery cell, next to an existing separator that insulates the anode and cathode. If that separator is punctured a short circuit occurs that typically causes the battery to overheat and in some circumstances catch fire. Panasonic said its insulation layer ensures that the battery won't overheat even in the event of a short circuit.
