New water-based lithium-ion battery will never explode in your face

Collaborating with the military, University of Maryland researchers made a 4-volt lithium-ion battery that runs on an aqueous-based electrolyte. With no organic solvents in its composition, the battery can’t possibly ignite or explode like the typical non-aqueous lithium-ion variety.

OK, now someone please send Samsung a memo.

“In the past, if you wanted high energy, you would choose a non-aqueous lithium-ion battery, but you would have to compromise on safety. If you preferred safety, you could use an aqueous battery such as nickel/metal hydride, but you would have to settle for lower energy.

“Now, we are showing that you can simultaneously have access to both high energy and high safety.”

Previously, the same team demonstrated an aqueous battery back in 2015. That version could deliver only 3 volts but, also had a very poor cycling ability.
