New aqueous lithium-ion battery improves safety without sacrificing performance

As the lithium-ion batteries that power most phones, laptops, and electric vehicles become increasingly fast-charging and high-performing, they also grow increasingly expensive and flammable. Engineers have now demonstrated how they could — by using aqueous electrolytes instead of the typical organic electrolytes — assemble a substantially safer, cost-efficient battery that still performs well.
