The invention discloses a lithium-rich manganese-based anode material and a method for manufacturing the same. The method includes steps of (a), providing mixed solution containing lithium compounds, nickel compounds and manganese compounds, optional titanium compounds, optional iron compounds, optional cobalt compounds or an optional combination of the titanium compounds, the ion compounds and the cobalt compounds; (b), adding complexing agents, catalysts and surfactants into the mixed solution to form pre-coagulated substances; and (c), calcining the pre-coagulated substances to obtain the lithium-rich manganese-based anode material Li[LixNiaMnbM1-a-b-x]O2 or a combination of lithium-rich manganese-based anode materials. The complexing agents, the catalysts and the surfactants are used for forming the pre-coagulated substances, the complexing agents contain resorcinol and formaldehyde, in the molecular formula of the lithium-rich manganese-based anode material, the M represents Ti, Fe, Co or a combination of the Ti, the Fe and the Co, the x is larger than 0 and is smaller than or equal to 0.4, the a is larger than 0 and is smaller than or equal to 0.5, the b is larger than or equal to 0.33 and smaller than or equal to 0.6, and a result of 1-a-b-x is larger than or equal to 0. The lithium-rich manganese-based anode material is of a multi-channel porous structure, is small in grain size, uniform in grain distribution, advanced in porosity and stable in electrochemical performance.
