Batteries composed of a cadmium amalgam electrode and a cadmium-lead amalgam electrode have an electromotive force of about 1.015 mV at 20 ° C. The battery has high stability and good reproducibility. This paper introduces the composition and structure of the battery, and obtains the emf-temperature equation, the recovery characteristics after charging and discharging, the temperature hysteresis effect, and the battery internal and external resistance ratio through experiments.
