Beschreibung
Zusammenfassung:	A Li-ion battery includes a cathode; an anode having a primary active material, conductive carbon, binder, and reserve material; and a separator between the cathode and anode. The reserve material has a reaction potential between a lithium reaction potential and a primary active material reaction potential. The reserve material is configured to intercalate with lithium at the reaction potential responsive to the primary active material being fully intercalated to inhibit lithium plating on the anode.
