Nevertheless, the inevitable volume expansion of Ga\u2010LM during lithiation cannot be accommodated by rigid encapsulation, causing electrical isolation and rapid capacity decay. This study exploits the in\u2011situ phase separation of eutectic gallium indium (EGaIn) alloy, enabled by electrospinning\u2011derived carbon encapsulation, to generate a 3D carbon nanofiber (CNF) network comprising yolk\u2010shell Ga\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>3<\/jats:sub>\n                    @CNF structures and uniformly dispersed In nanoparticles.

As confirmed by finite element analysis (FEA) and density functional theory (DFT) calculations, the yolk\u2010shell structure accommodates volume change and relieves interfacial stress, while the In nanoparticles mitigate ohmic polarization and provide atomic\u2010scale Li adsorption sites. Benefiting from these merits, the phase\u2010separated electrode achieves outstanding cycling stability, with a capacity decay of merely 0.014% per cycle over 2000 cycles at 3\u00a0A\u00a0g\n                    <jats:sup>\u22121<\/jats:sup>\n                    , and a superior rate capability of 579.3\u00a0mAh\u00a0g\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 3\u00a0A\u00a0g\n                    <jats:sup>\u22121<\/jats:sup>\n                    .
