How does a sodium-ion saltwater battery work?

The sodium-ion battery works on a very simple principle: a plastic crate is filled in two compartments. A sodium-ion battery contains a salt and a freshwater reservoir. On contact, an electric current is created. When the battery charges, the fresh and salt water are separated again. The battery also contains manganese oxide and carbon-titanium phosphate.


A sodium-ion battery is low-maintenance, environmentally friendly and lends itself well to domestic use. The saltwater battery has a service life of up to 20 years.
