Abstract:
The present disclosure relates to an anode material, a method for preparing the same, and a lithium ion battery, which belong to the technical field of energy storage materials. The anode material includes a LixMySiO4 material, a carbon material and nano-silicon. The LixMySiO4 material and the carbon material has a network structure, independently forming a first skeleton and a second skeleton in the anode material respectively. The first skeleton and the second skeleton are entangled with each other, and the nano-silicon is distributed in the matrix or/and on the surface of LixMySiO4 material. In the LixMySiO4 material, the values of x and y satisfy charge balance, and M includes a metal element capable of reducing silicon oxides, the metal element excludes Li. The anode material has better electrical conductivity, more stable structure, lower volume expansion, higher electrical conductivity, higher first efficiency and excellent rate performance.
