Document Type and Number:
Japanese Patent JPWO2022163538
Kind Code:
A1
Abstract:
A lithium secondary battery includes a positive electrode that absorbs lithium ions during discharge and releases the lithium ions during charge, a negative electrode at which a lithium metal deposits during charge and from which the lithium metal dissolves during discharge, and a non-aqueous electrolyte having lithium ion conductivity. The surface of the negative electrode is covered with a protective layer. The protective layer includes a block polymer in which a first polymer segment having a repeating structure of a monomer unit A and a second polymer segment having a repeating structure of a monomer unit B are bound together.
