FIELD: electrodes.
SUBSTANCE: invention in particular relates to a lithium electrode used for lithium-ion secondary batteries. The electrically conductive structure layer has a recess with a hole on one side, and a layer of lithium metal is located at the bottom of the recess. The solid electrolyte layer and the electrolyte storage layer are arranged in series thereon. When the lithium metal is applied, the applied lithium metal is limited by the solid electrolyte layer to push and squeeze the electrolyte storage layer.
EFFECT: effective limitation of the growth of lithium dendrites, increasing the safety of the battery.
