Technology Description
e-Zn is developing a long duration battery technology that utilizes Zn metal as the energy carrier. The battery cell is made of two electrodes and a basic electrolyte with dissolved Zn.During charging, Zn deposits onto the top anode electrode, mechanical wipers knock it free,and it falls to the bottom of the cell. The energy is stored in these precipitated zinc metal bonds. To discharge the cell, the air cathode reacts with the zinc returning it to solution (see limitation note on air cathodes below).System is controlled and monitored with their proprietary software.Product plans are for a 40kW system with 24-hour storage. Sizing would include a 40kW/1MWh offering in a shipping container. In the lab and pilot demonstration they have measured performance efficiency of 50-60%with reaction times of less than 1 second.
