Eutectic gallium-indium liquid metal (EGaIn-LM), with a considerable capacity and unique self-healing properties derived from its intrinsic liquid nature, has gained tremendous attention for lithium-ion batteries (LIBs) anode applications. However, the fluidity of the LM could trigger continuous consumption of the electrolyte, and its liquid-solid transition during the lithiation/de-lithiation process may result in the rupture of the solid electrolyte interface (SEI). Herein, we employed LM as an initiator to in-situ assemble the 3D hydrogel framework for dynamic encapsulating itself, the LM nanoparticles could be homogeneously confined into the hydrogel-derived carbon framework (HDC) after calcination...
