Electrical cell has sulphonic acid as electrolyte and positive and negative electrodes, the positive electrode consisting of a base of titanium nitride with a cover of lead peroxide, and the negative electrode consisting of lead. The negative electrode pref. has a copper base. A non-polarising layer is pref. present between the titanium nitride base and the lead peroxide cover the positive electrode. This non-polarising layer pref. consists of a gold film on the titanium nitride base. The electrical cell is suitably in the form of an accumulator. Such accumulators have a higher capacity per unit weight than conventional lead accumulators. |
