Electrolysis - Chemical modifications, oxidation and reduction produced by passing an electric current through an electrolyte.
Electrolyte - A substance which dissociates into ions (charged particles) when in aqueous solution or molten form and is thus able to conduct electricity. It is the medium which transports the ions carrying the charge between the electrodes during the electrochemical reaction in a battery.
End voltage - The prescribed voltage that indicates that the discharge is complete. (see also Cut-off voltage)
Energy Content - The absolute amount of energy stored in a battery expressed in Wh or Joules
Energy density - The amount of energy stored in a battery. It is expressed as the amount of energy stored per unit volume or per unit weight (Wh/L or Wh/kg).
