Charge retention
The ratio, usually expressed as a percentage, between the capacity that can be discharged from a battery after it has been fully charged under specified conditions, allowed to stand for a specified time at a specified temperature, and not recharged, and the nominal capacity of the battery.

Utilization rate of active material
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.
Volumetric power
The ratio of the power output of a battery to its volume. Also known as "volume power density."
2024-06-25 15:56
Gravimetric power
The ratio of the power output of a battery to its mass. Also known as "power density."
Gravimetric energy
The ratio of a battery's energy to its mass. Also known as "mass energy density."
Capacity per gram
The capacity released by the internal active material of a battery during discharge divided by the mass of the active material. Note: Specific capacity is typically expressed in milliampere-hours per gram (mAh/g). Sometimes, the calculation of specific capacity includes the mass of all non-active materials, such as conductive additives and binders.

Recovery capacity
The capacity that can be discharged from a battery after it has been fully charged under specified conditions, allowed to stand for a specified time at a specified temperature, then fully recharged, and discharged again.
2024-06-25 15:48
Residual capacity
The remaining capacity of a battery that can be discharged when the battery has been used for a period of time under specified conditions (such as discharge or storage) before continuing to discharge.
Rated capacity
The capacity value of a battery cell, module, battery pack, or system measured under conditions specified by the manufacturer and declared by the manufacturer. Note: Rated capacity is typically expressed in ampere-hours (Ah) or milliampere-hours (mAh).

Discharge capacity
The capacity value of a battery's output measured under specified conditions. Note: Discharge capacity is typically expressed in ampere-hours (Ah) or milliampere-hours (mAh).
