Lithium-ion (Li-ion) battery technology has historically been the power cell of choice ... many modern phones now commonly feature lithium-polymer (Li-poly) batteries, a suitable alternative ...
While debugging a strange battery failure in a manufacturing process, [Josh] discovered a new (to us) LiPo battery failure mode. Different battery chemistries react differently to temperature.
"The polymer network undergoes a simple recycling process, which we expect will extend the lifespan of electronic devices and wearable sensors, significantly reducing electronic waste." More ...
