Lithium ion batteries represent a type of dry cell battery well-suited for use in cell phones, due to its high energy density, or its power stored versus weight. Photo-voltaic (PV) cells—almost like solar cells—capture the radiation and convert it to electricity. The action of the acid removes electrons from one plate and accumulates them on the other plate. Natsu ran into the large cave screaming for his father, his tear soaked scarf flapping behind him. There are two types of voltaic cells :(1) Primary (2) Secondary\f Primary CellsA cell which acts as a source of electricity without being previously charged by an electrical current from an external source is called primary cell.
