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.”
