The thermodynamics of the leaching reactions was analyzed to determine the feasibility of leaching impurities and crystallizing FePO4 from LES.
11.5: Batteries
Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.
