By designing a solid electrolyte that is rigid on one side and soft on the other, researchers have fabricated a lithium-metal battery that completely suppresses dendrite formation—a major safety hazard that can cause fires ...
If you add more lithium to the positive electrode of a lithium-ion battery - overstuff it, in a sense - it can store much more charge in the same amount of space, theoretically powering an electric car 30 to 50 percent farther ...
