The storage battery with bipolar membranes

The storage battery consists of a three-compartment electrodialysis cell with a bipolar membrane. The main characteristics of the electric energy source are evaluated when applied to the regimes of charge, discharge and self-discharge. These regimes are subjected to the experimental study to verify the theoretical predictions. The experimentally obtained values of the performance of the battery are compared with that of the known battery types. The comparison of the yield density of 0.5 and 80 W/kg (lead battery) makes it obvious that an industrial application is scarcely conceivable. Membranes with better permselectivity are needed.
