| titleOfInvention | A kind of porous composite negative pole material of lithium ion battery and preparation method thereof |
| abstract | The present invention relates to porous composite negative pole materials of a kind of lithium ion battery and preparation method thereof.The composite negative pole material is a kind of composite material with porous structure, with the transition metal oxide M of porous structure x O y For skeleton, nano-silicon is filled in hole.The preparation method of the composite negative pole material, comprising: disperse transition metal salt and nano-silicon in solvent, stir and be packed into reactor；It is co-precipitated or is spray-dried to obtain transition metal carbonate presoma；The transition metal carbonate presoma is calcined at 400-1000 DEG C, and the composite material with porous structure is prepared.The porous composite negative pole material provides the reserved space of silica-base material expansion, so that integral material volume expansion during embedding de- lithium is smaller, and then improves its cycle performance, and synthesis technology is simple, is suitable for industrialized production. |
