They have several advantages over traditional lithium-ion cells. For example, a lithium polymer cell can deliver as much current as a lithium-ion cell but without the risk of over discharge or thermal runaway that can damage conventional cells. The latter makes them useful for applications where a cell must operate in high temperatures or for long periods with frequent charging and discharging. Lithium polymer cells also offer a significantly longer shelf life than conventional batteries, which means they’re well-suited to the rise of electric vehicles, wearable electronics, and other appliances with long lifespans. However, their power-dense capabilities come with a tradeoff: they have more excellent internal resistance and capacity than lithium-ion cells.
