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. In research published recently in Energy Storage Materials, a team of engineers at Rensselaer Polytechnic Institute 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.
