Provided is anode material and battery. The anode material includes silicon, and at least a portion of the silicon is present in the form of crystalline silicon. Based on a mass content of the silicon in the anode material being 100%, a mass content of the crystalline silicon is A %, and an average silicon grain size of the crystalline silicon is B nm. The anode material satisfies the following features: 0.3≤A/B≤60 and 6≤A+B≤75. According to the anode material and the battery provided in the present disclosure, the anode material can achieve an ideal balance among cycling performance, capacity utilization, and rate performance.
