  As a new type of self-healing material, room-temperature liquid metal (LM)
composed of Ga, In and Sn is a promising anode in lithium-ion batteries (LIBs).
It is difficult to directly prepare an electrode slurry with pure LM. Here, the
LM electrode slurry was successfully prepared by simple high-speed stirring
method. The LM in the slurry was evenly distributed in the form of liquid
particles (average size 100 {\mu}m) and no aggregation occurred. The initial
discharge specific capacity of LM is 1148 mAh g-1, and the stable discharge
specific capacity is 350 mAh g-1. Cyclic voltammetry measurements show that
three pairs of obvious reduction peaks and oxidation occur in LM anodes at 0.37
V,0.67 V,1.02 V and 0.72 V,0.79 V,0.97 V. In the process of lithium insertion,
the LM undergoes a liquid-solid phase transition, and when it is delithiated,
it will be converted into a liquid phase. The SEI film consumed active lithium
and electrolyte during the long cycle, resulting in loss of reversible
capacity.
