Seawater Battery Could Replace Lithium-Ion

Dec-10-16 An innovative new battery made from seawater could provide an affordable alternative to lithium-ion batteries.

Developed by a team from Ulsan National Institute of Science and Technology, the sodium oxygen battery features seawater as a catholyte, which is a cathode and electrolyte that are combined. The seawater’s constant flow would provide the sodium ions and water that produce the charge, and a catalyst of porous cobalt manganese oxide nanoparticles were used to create a large surface area and speed the process.

According to the team, the battery provides a discharge of about 2.7 volts, compared to 3.6 for a lithium ion battery.
