An anode for a galvanic cell is constructed from an anode material containing a main component, which releases lithium ions during a discharge process of the galvanic cell, and at least one additive. The at least one additive has an electrochemical potential which is higher with respect to elemental lithium than an electrochemical potential of the main component with respect to elemental lithium. The at least one additive has a charging capacity and a discharging capacity, and the charging capacity does not deviate from the discharging capacity by more than 10%.

An electrode for an energy accumulator comprises a substrate, an active anode layer having an active anode material, the active anode material being at least partially a lithium, a lithium alloy and/or a lithium intercalation material, at least one lithium-ion-conducting layer having a material composition which gradually changes over a layer thickness and has at least one lithium-ion-conducting component. A method for forming an electrode for an energy accumulator, and a lithium-ion battery comprising an electrode are also disclosed.
