Here, low-cost raw materials are used for the preparation of a graphite/silicon@carbon composite negative electrode material, which synergizes ball milling, molten salts electrolysis and carbon coating. Silica is in situ electrochemically reduced to silicon on the flaky graphite serving as the conducting substrate during the electrolysis process.
In the first embedded/lithium process of Si/Cu 3 Si negative electrode, with the negative shift of potential, the reduction peak of embedded lithium appears near 0.04 V. This peak represents the lithium embedded process of the active material crystalline silicon, forming an amorphous lithium-silicon alloy (α-Li x Si y).
