Positive electrode is the cathode during discharge negative electrode is the cathode during chargeĬapacity: maximum amount of electrical current that can be withdrawn from a battery cell under specified conditions. The energy is referenced to the discharge at a constant current for a measured period of time until a specified cut-off voltage is reached.Ĭathode: electrode where reduction takes place during electrochemical reaction. As the battery discharges, the cadmium progressively changes into cadmium hydroxide (CdOH2).Ĭadmium hydroxide - Active material used at the negative electrode of the Nickel-cadmium cell.Ĭadmium salt - A chemical compound in which the hydrogen atom as been replaced by the cadmium atom: e.g.) 2HNO3 + Cd(OH)2 -> Cd(NO3)2 + 2H2O cadmium nitrate.Ĭapacity - The electric energy content of a battery expressed in ampere hours. When the battery is charged, the negative electrode surface consists of cadmium. This metallic element is the chemically-active material of the Nickel-cadmium battery's negative electrode. The capacity of NiCd batteries is commonly rated at 1C, meaning that a 10000mAh battery would be discharged at 10000mA for one hour.Ĭadmium - Chemical symbol: Cd. For example, the 0.1 current for N-1300SC is equal to 1300 X 0.1 = 130mA.Ĭ-rate - Unit by which charge and discharge times are scaled. The charge-discharge current is specified in terms of a multiple of C. Button cells are manufactured with circular disc electrodes that are separated with a separator sheetĬ - C designates the nominal capacity of the battery.
"Battery" is the common term for a single cellīutton Cell: a battery cell with overall height less than its diameter. Negative electrode is the anode during discharge positive electrode is the anode during chargeĪssembled battery - Any battery composed of multiple cells.īattery (Battery Pack): two or more electrically connected cells in a series/parallel arrangement, designed to create the desired voltage/capacity.
