problems, including interfacial stability and contact
issues, severely plague the practical application of Li metal anodes.
Here we report an interfacial regulation strategy that stabilizes
the Li metal-gel electrolyte interface through in situ constructing a stable solid electrolyte interphase (SEI) layer.
By stabilizing the interface of Li metal anodes, the gel electrolyte
enables dendrite-free morphology and high plating/stripping efficiency.
A systematic analysis further confirms that the formed SEI layer is
responsible for homogeneous deposition and stable cycling performance.
Benefiting from the interfacial stability between electrodes and electrolytes,
the lifespan of Li metal batteries is extended.
