Electrolyte additives for improved lithium-ion battery
Because battery shutdown is undesirable, overcharge protection by means of redox shuttle additives that enable continued operation of LIBs has been investigated widely [6, 7]. This mechanism protects the battery against overcharging because the potential of the positive electrode does not exceed the oxidation potential of the redox shuttle.
