What is a sodium-ion battery?

A sodium-ion battery (also known as a saltwater battery) is a unique electrochemical energy storage system, based on saltwater electrolyte. Fundamentally, a saltwater battery comprises salt and a freshwater reservoir. During its operation, the salt- and freshwater are segregated, prompting the migration of sodium-ions from one side to the other. This ion flow generates an electric current, suitable for powering various devices. A saltwater battery offers low-maintenance, eco-friendliness, and versatility for diverse applications. It boasts a lifespan of up to 20 years.
