Swedish battery developer Enerpoly has won a two-year $600,000 grant from government agency Vinnova to help it develop zinc-ion battery technology.
It uses zinc metal as anode, manganese dioxide as cathode and a water-based electrolyte. Upon discharge, the zinc metal dissolves to zinc-ions on the anode.
The 3 kWh battery is suited for 2 – 10 hour durations, the company said. It has tested the battery against the UL 9540A standard.
“The main focus of this awarded Vinnova grant will be to advance the complex industrial processes for fabricating electrodes for zinc-ion batteries,” the company said in a statement.
“Electrode fabrication represents the most critical and challenging step in scaling up zinc-ion technology to the megawatt-hour production levels required for large-scale stationary storage applications.”
It said it will use the grant to increase the volume and speed of various electrode fabrication steps up to 50-fold, and reduce scrap.
