Self‐Adapting Electrochemical Grinding Strategy for Stable ...
· MgH 2 is utilized as the grinding aid to electrochemically grind micronsized Si particles. During ECG process, the lithiation processes of MgH 2 and Si occur at different potentials and both result in appreciable volume expansion, leading to a strong internal stress inside the electrode. With this strong internal stress, the lithiation products of MgH 2,, Mg and LiH, would migrate into ...
