A team of researchers from University of Maryland and the U.S. Army Research Lab invent a new and advanced cathode. It undergoes a chemical transformation that results in changeable solid salt coating in a water based battery.
Researchers believe that improvising the prototype of water in salt batteries will help successfully develop high energy batteries.
Cathode Chemistry in Water in Salt Battery
Chongyin Yang, an assistant researcher at University of Maryland states, by combining high safety aqueous system with high energy aqueous system, the new cathode chemistry operates in ‘water in salt ‘electrolytes. Earlier the researchers invented a cathode which was high in energy but did not have conversion metal.
The researchers deploy changeable halogens in graphite structure because they have super concentrated electrolyte. The water-based salt solution with graphite anode can build and form a shielding layer inside the battery. This makes the battery impressively durable with high energy.
This can generate high energy density that can surpass non-water-based lithium ion batteries. The new battery yields 25% higher energy than the conventional lithium ion battery. The new cathode can hold twice the amount of energy storage that is 240 miliamps in comparison to ordinary cathode in cell phones and laptops.
Currently, scientists are testing the battery which is small as a shirt button. Further, research is underway to make this battery a practical solution. The aim is to start manufacturing such batteries. This, in real-time scenarios can ensure safety and toxicity in important areas. Thus, non-flammable batteries can be a boon to vessels, spaceships, and aircraft industries.
