☞ In the trough battery, copper and zinc plates, connected in pairs, divide the trough into cells, which are filled with an acid or oxidizing liquid; the effect is exhibited when wires connected with the two end-plates are brought together. In Daniell's battery, the metals are zinc and copper, the former in dilute sulphuric acid, or a solution of sulphate of zinc, the latter in a saturated solution of sulphate of copper. A modification of this is the common gravity battery, so called from the automatic action of the two fluids, which are separated by their specific gravities. In Grove's battery, platinum is the metal used with zinc; two fluids are used, one of them in a porous cell surrounded by the other. In Bunsen's or the carbon battery, the carbon of gas coke is substituted for the platinum of Grove's. In Leclanché's battery, the elements are zinc in a solution of ammonium chloride, and gas carbon surrounded with manganese dioxide in a porous cell. A secondary battery is a battery which usually has the two plates of the same kind, generally of lead, in dilute sulphuric acid, and which, when traversed by an electric current, becomes charged, and is then capable of giving a current of itself for a time, owing to chemical changes produced by the charging current. A storage battery is a kind of secondary battery used for accumulating and storing the energy of electrical charges or currents, usually by means of chemical work done by them; an accumulator.
