Abstract: Provided is a prelithiation material, comprising a lithium-containing compound and an inorganic non-metallic reductive agent. Further provided is a method for preparing the prelithiation material of the present invention. Further provided is use of the prelithiation material of the present invention in a lithium ion battery. By mixing the prelithiation material provided by the present invention with a positive electrode material or coating the side of a separator near the positive electrode with the same, a battery is assembled, and during first cycle, active lithium can be released so as to compensate active lithium lost from a negative electrode. The prelithiation material provided by the present invention has a good compatibility with currently commercially available positive and negative electrodes, and is very suitable for current secondary lithium ion batteries.
