During the decomposition of batteries, the metals in the battery, such as zinc or lithium, react with the electrolyte to form metal salts, gases, and other byproducts. The decomposition of batteries can release harmful gases, such as hydrogen gas, which can be flammable and contribute to the risk of explosion or fire.
