| titleOfInvention | High-rate lithium iron phosphate lithium ion battery positive plate and preparation method thereof |
| abstract | The invention relates to the technical field of positive electrode materials, in particular to a high-rate lithium iron phosphate lithium ion battery positive electrode plate and a preparation method thereof. According to the invention, carbon fiber powder is coated on two sides of a lithium iron phosphate/carbon fiber layer after being respectively subjected to melamine modification and phosphoric acid modification, and is used as an artificial SEI film to pre-coat the lithium iron phosphate layer, and the lithium iron phosphate layer is self-assembled and fixed in an electrolyte system, so that the composite cathode material with the porous carbon fiber framework loaded with the artificial SEI @ lithium iron phosphate is formed. The carbon fiber powder self-assembled skeleton has certain lithium intercalation capacity, can be used as an inorganic layer in an SEI film, has higher lithium ion conduction capacity, can effectively relieve the overgrowth of the SEI film in a formation process, and reduces the loss of irreversible capacity. According to the invention, the artificial SEI organic phase is pre-coated on the lithium iron phosphate particles, so that the first effect and the rate capability of the anode material can be effectively improved. The process is simple and controllable, and is suitable for large-scale industrial production. |
