Korean researchers triple battery lifespan by breaking electrolyte design rules

Lithium-metal batteries can store more energy than lithium-ion cells, but the electrolyte reacts with the anode and capacity fades fast. Researchers at UNIST and KAIST mixed ethylene carbonate and sulfolane, two solvents once deemed unsuitable; the molecules attract each other, loosening their grip on lithium ions. A test cell held 80 percent of its capacity after 150 cycles.
