Batteries are devices that convert chemical energy contained in its active materials into electric energy throughout electrochemical red-ox reactions. Theoretically, the energy provided by a battery depends only on its active substances. Practically, just a part of a battery's capacity can be used, due to the nonreactive substances that add up to the process and which influence the magnitude of the...
