摘要:
An anode material of a lithium secondary battery. The anode material includes a plurality of silicon particles, each silicon particle comprising a silicon core covered by a coating layer containing at least one metal oxide, preferably TiO2, ZrO2, or a combination thereof. The invention also provides a method of fabricating the anode material using chemical vapor deposition or sol-gel process.
