Batteries based on water are one step closer to being commercially viable, thanks to a new design that drastically extends their lifespan. The first application could be in powering e-scooters, say researchers.

Lithium-ion batteries, which are currently used in everything from smartphones to electric cars, offer many benefits such as a high energy density, but can also explode or catch fire when they fail because they use dangerous organic solvents as an electrolyte in combination with a lithium anode.
