【Answered】Do Lithium Batteries Leak? How to Prevent?

At its core, a lithium-ion battery utilizes reversible redox reactions involving the shuttling of lithium ions between two electrodes - a cathode and an anode - to produce electricity. This shuttling enables the battery to repeatedly store and release power through insertion and removal of lithium ions.
