Abstract
Disclosed is an anode for a lithium metal battery. The anode includes a copper current collector and an SEI layer formed on a surface of the copper current collector, the SEI layer comprising Li2S2/Li2SX, LiXN, LiCl, and Li+ (X≥3). Accordingly, a uniform and stable SEI layer can be formed on a copper current collector, thereby suppressing lithium dendrite formation.
Claims10
An anode for a lithium metal battery, comprising:
- a copper current collector;
- and
- an SEI layer formed on a surface of the copper current collector, the SEI layer comprising Li2S2/Li2SX LiXN, LiCl, and Li+1(X≥3).
A method for manufacturing an anode for a lithium metal battery, the method comprising the steps of:
- preparing a copper current collector;
- and
- growing an SEI precursor comprising a copper-thiourea complex by surface-treating the copper current collector.
