Ohmic polarization

Electrode polarization accompanying electrochemical reduction reactions.

The ratio between the actual capacity obtained from a battery and the theoretical capacity of the active material it contains, often expressed as a percentage.Note: In most cases, the utilization rate of the active material is different for the positive and negative electrodes.

The ratio of the power output of a battery to its volume. Also known as "volume power density."

The ability of a battery to store electrical energy relative to a new battery.Note: It is expressed as a percentage and quantitatively describes the performance state of the battery during its lifetime, from the beginning to the end of its life.

The maximum current that a battery can deliver to an external circuit with zero resistance or with the battery voltage reduced to near zero volts.Note: Zero resistance is an imaginary condition, and in reality, the short-circuit current is the maximum current that flows in a circuit with a resistance significantly lower than the internal resistance of the battery.

The process in which a battery outputs the electrical energy it generates to an external circuit under specified conditions.Note: During this process, chemical energy is converted into electrical energy.
