An illustration of the Chalmers design for a lithium sulfur battery. The highly porous quality of the graphene aerogel allows for high enough soaking of sulfur to make the catholyte concept worthwhile.
A new composite battery cathode incorporates solid LiBr and LiCl crystals (blue) with graphite (grey). Combining this high-capacity cathode with a pure graphite anode and a water-based electrolyte, researchers have made a safe, high-energy and inexpensive lithium-ion battery.
