A method of molten state lithium source surface tension is reduced so as to improve anode material for lithium-ion batteries high temperature solid-phase sintering process, the present invention relates to a kind of methods improving anode material for lithium-ion batteries high temperature solid-phase sintering process, belong to lithium ion battery material and its manufacturing process technology field.The problems such as being unevenly distributed the purpose of the present invention is to solve the lithium source because of molten state during anode material for lithium-ion batteries high temperature solid-phase sintering and infiltrate the problem that not exclusively caused reaction is unbalanced and reaction is insufficient, and then improving the high rate performance, cyclical stability and thermal stability of charge and discharge cycles process in which materials.The process that the present invention improves carries out according to the following steps：One, lithium source pre-processes；Two, lithium source is mixed with persursor material；Three, lithium source and persursor material fully infiltrate；Four, high temperature sintering.Material prepared by the present invention is used for anode material for lithium-ion batteries.
