Self-sacrificial organic lithium salt enhanced initial Coulombic efficiency for safer and greener lithium-ion batteries.

A 3,4-dihydroxybenzoic acid dilithium salt is prepared and proposed as an cathode additive to offset the loss of lithium. As Li+ is extracted from the salt, the organic part is taken up into the electrolyte simultaneously leaving no remaining material, leading to a safer and greener lithium-ion battery.
