A research team from the University of Maryland and the US Army Research Laboratory have created a lithium-ion battery that utilises water-salt electrolyte solution that can hit 4 volts without risk of explosion. The new battery, which is based on an existing technology developed by researchers at the National Renewable Energy Laboratory, could be used in electric cars or other applications where high voltage would not pose any safety risks. The researchers used a gel polymer electrolyte coating for the graphite or lithium anodes in its batteries, allowing for slower reactions should damage occur, preventing issues such as fire and explosive reactions.
