WIPO Patent Application WO/2018/236166
Kind Code:
A1
Abstract:
The present invention relates to a lithium secondary battery which is prepared as an anode-free battery and has lithium metal formed on an anode current collector by means of charging. The lithium secondary battery has lithium metal formed while blocked from the atmosphere. Therefore, a surface oxide film (native layer), which is formed on an existing anode, is not substantially produced and thus degrade in battery efficiency and lifetime characteristics due to same can be prevented.
