The system of active materials within a cell that provides electrical energy storage through an electrochemical reaction.

 The terminal of a battery from which electrons flow in the external circuit when the cell discharges.

 The permeable membrane that allows the passage of ions, but prevents electrical contact between the anode and the cathode.

 One ampere-hour is equal to a current of one ampere flowing for one hour. A unit-quantity of electricity used as a measure of the amount of electrical charge that may be obtained from a storage battery before it requires recharging.

 The number of ampere-hours which can be delivered by a storage battery on a single discharge. The ampere-hour capacity of a battery on discharge is determined by a number of factors, of which the following are the most important: final limiting voltage; quantity of electrolyte; discharge rate; density of electrolyte; design of separators; temperat [..]

 In a primary or secondary cell, the metal electrode that gives up electrons to the load circuit and dissolves into the electrolyte.

 Batteries with water-based electrolytes.

 The total battery capacity, usually expressed in ampere-hours or milliampere-hours that are available to perform work. This depends on factors such as the endpoint voltage, quantity and density of electrolyte, temperature, discharge rate, age, and the life history of the battery.

 A device that transforms chemical energy into electric energy. The term is usually applied to a group of two or more electric cells connected together electrically. In common usage, the term “battery” is also applied to a single cell, such as a household battery.

 There are, in general, two types of batteries: primary batteries, and secondary storage or accumulator batteries. Primary types, although sometimes consisting of the same active materials as secondary types, are constructed so that only one continuous or intermittent discharge can be obtained. Secondary types are constructed so that they may be re [..]
