Preparation of room temperature liquid metal negative electrode for lithium ion battery in one step stirring

Abstract As a new type of self-healing material, room-temperature liquid metal (RLM) composed of Ga, In , Sn is a promising anode in lithium-ion batteries (LIBs). However it is difficult to prepare an electrode slurry with pure RLM directly. Here, a simple high-speed stirring method successfully prepared the RLM electrode slurry . The RLM in the slurry evenly distributed in the form of liquid particles, and no aggregation occurred. The stable discharge specific capacity of RLM is 350 mAh g-1. Electrochemical tests show that RLM electrodes have excellent cycle stability and reversible capacity retention rate at different current densities.
