Aquion batteries use a saltwater electrolyte, a carbon titanium phosphate composite anode, and a manganese oxide cathode. Multiple Aspen 48S stacks can be added together to scale system size.
Aquion has been in commercial production since 2014. Aquion promotes the safety and environmental aspects of their batteries and markets them as the only ones in the world to be Cradle to Cradle Certified.
The Battery Test Centre installation consists of 8x Aquion batteries connected to a Victron MultiGrid inverter.
