Innovative Battery Technology
Revolutionizing energy storage with cutting edge materials for the best and most affordable battery.
Sidra Energy has created an aqueous aluminium air battery that uses sea water and runs on recycled low purity aluminium
Sidra’s unique selling point for it air batteries
Anode - uses recycled common low purity aluminium
Electrolyte - runs on either sea water or an optimised salt electrolyte
Cathode - cheap, safe and robust air electrodes
At the moment there are no commercially available aluminium air batteries. The companies that are working to commercialise aluminium air batteries use:
Anode - high purity and expensive to produce aluminium
Electrolyte – corrosive alkaline, usually sodium or potassium hydroxide
Cathode – silver nano particle or other exotic material that are expensive to produce.
Sidra’s use of sustainable materials and its mission statement to create a true commercially viable products has resulted in an Air Battery that is ready to meet the needs of it consumers.
The technology consists of a complete cell design. A cell has five components:
1. Anode
2. Cathode
3, Electrolyte
4. Separator
5. Current Collector
Anode: metal material in our case aluminium – uses recycled low purity aluminium
Cathode: proprietary air cathode made using special material.
Electrolyte: uses sea water or an optimised salt electrolyte to increase performance of the cell.
Separator: used for the correct function and transfer of ions in the cell
Current Collector: robust material connecting the active materials to output terminals.
Sidra Air Cell – in each component of the cell we have innovated
