Preparation method of anode energy storage material for battery

The invention discloses a preparation method of an anode energy storage material for a battery, which comprises the following steps: proportionally adding glucose and phenolic resin into a reaction kettle at normal temperature, stirring while heating to uniformly mix, and raising the temperature to 220 DEG C; stirring cannot be stopped during the heating period, so that a relatively complete cross-linking reaction occurs, and a product is of a net-shaped structure; raising the temperature from 280 DEG C to 500 DEG C under the stirring condition, stopping heating, transferring the product into a stainless steel container, and cooling; the cooled product enters a high-pressure flour mill and a superfine flour mill to be crushed, and the particle size of the cooled product is 5-11 microns; the crushed product is put into a crucible and then enters a tunnel kiln or a roller kiln to be sintered, after sintering, screening is conducted through a 500-mesh screen, demagnetization is conducted, finally, the obtained p
