New halogen conversion-intercalation chemistry enables high-energy density aqueous Li-ion battery

Green Car Congress

volts versus Li/Li +. Combining this cathode with a passivated graphite anode, the team created a 4V-class aqueous Li-ion full cell with an energy density of 460 Wh kg -1 of total composite electrode and about 100% Coulombic efficiency. After considering the electrolyte mass, the full-cell energy density still reaches 304 Wh kg ?1.
