Cell potential: The voltage of a battery is given by the equation Cell potential = (EC - EA) -|ηA - ηC |- i Rcell. To derive maximum voltage from a battery, the electrode systems should be designed to minimize over-potentials and internal resistance. b. Current: For efficient discharge, electrons should flow at a uniform rate. Current measures the rate of flow of electrons and is expressed in ampere per second. c. Capacity: Capacity is measured in ampere-hours (A h) and depends on the battery's size. d. Electricity Storage Density: This refers to the charge per unit mass stored in the battery. e. Energy Efficiency: Defined as the percentage of energy released on discharge to energy required for charging. f. Cycle Life: Refers to the number of charge-discharge cycles before failure. g. Shelf Life: The storage period during which a battery retains performance. h. Energy Density: The ratio of energy available from a battery to its mass. i. Power Density: The ratio of power available from a battery to its mass.
