Salt Water Electricity Batteries

“How can we make batteries that use salt-water as a catalyst?”

 

Traditional lithium-based batteries are too corrosive to operate in salt-water. However, a start-up built out of MIT may have made a new type of battery that this won’t be a problem for. Using alloyed aluminum, a primarily nickel-based alloyed cathode alloy, and an alkaline electrolyte that’s positioned between the electrodes that can split ocean water at the cathode into hydroxide anions and hydrogen gas. These hydroxide anions interact with the aluminum anode, creating aluminum hydroxide and releasing electrons. These Salt Water Electricity Batteries have a very promising design that can revolutionize the submarine industry.
