With the increasing demand for higher energy lithium-ion batteries (LIBs), it is imperative to develop high-capacity electrode materials [1–4]. Due to the unique electrochemical Li-alloying reactions, Li-alloys offer high theoretical capacity, especially lithiumrich phase alloys, which exceeds the theoretical capacity of graphite anodes [5–7]. Phase-transition, which significantly influences lithium alloy reactions, determines high voltage hysteresis,low Coulombic efficiency (CE), and short cycling life [8,9].

With pursuing high energy density batteries,traditional graphite anode could be unable to meet current needs[1-4].The high-capacity anodes have attracted increasing attention,such as lithium anodes and alloy-type anodes[5-8].Silicon anode,as a high-capacity alloy-type anode(3579 mAh/g),has attracted great attention[9].However,due to its unique electrochemical mechanism,significant changes in volume and morphology during charge/discharge process could lead to the decrease in cycling stability[9,10].Therefore,it is still challenging for silicon anode in tackling volume expansion and unstable interfaces.
