UCSD, South 8 team report improved liquefied-gas electrolytes for Li-metal batteries

Green Car Congress

Finding cost-effective ways to replace the graphite anode in commercial lithium-ion batteries is of great interest because it could lead to lighter batteries capable of storing more charge, via a 50% increase in energy density at the cell level. In contrast, most of conventional electrolytes fail to work below minus 20 ?C. 1721646).
