Abstract
The present invention relates to Li-ion cells area, particularly relates to lithium source material and preparation method thereof and use in Li-ion cells. Wherein the lithium source material which is represented by a formula LiFeMOR, wherein M represents one or more of transition metal elements, R represents halogen element, 0≤x≤0.9, 0<z≤0.2, 3.5<y≤[5(1−x)+6x]. The lithium source material of the present invention which is lithium deficient relative to its stoichiometric lithium formulation, is a lithium source additive material to the cathode material for Li-ion cells, and exhibits high capacity and high stability.
