| titleOfInvention | The silica-based composite negative pole material of a kind of lithium ion battery |
| abstract | The present invention relates to the silica-based composite negative pole material of a kind of lithium ion battery, its be in porous silica carbon skeleton dispersed size lower than the material of 0.3 μ m. The present invention also provides the preparation method of this composite negative pole material, comprise: material is dispersed in liquid organosiloxane monomer, to the precursor solution that adds successively acid solution, curing agent and the amorphous carbon source of alcohol-water in above-mentioned dispersion liquid, insulation is solidified mixed solution. Predecessor after solidifying, in protective atmosphere, obtains bulk silicon based composites through high-temperature calcination. Bulk silicon based composites obtains the silica-based lithium ion battery negative material of various different-grain diameters through ball mill crushing. Firmly and be evenly distributed in porous silica carbon skeleton, this structure can effectively be born the bulk effect of bringing because of doff lithium for material in this silica-based composite negative pole material, has charging and discharging capacity and can be in harmonious proportion the high feature of electrochemistry cyclical stability. |
