Gel batteries: advantages, disadvantages and operation
A gel battery works by using a gel electrolyte instead of a liquid electrolyte, as in conventional lead-acid batteries. The gel is a viscous material that contains sulfuric acid, water and silica, and acts as an ion conductor. During charging, an electrical current is applied to the battery, causing a chemical reaction in the gel.
