| titleOfInvention | Iron phosphate lithium battery |
| abstract | In order to overcome the problem of lithium dendrites and iron ion dissolution being present in existing high-compaction lithium iron phosphate batteries, provided in the present invention is a lithium iron phosphate battery, comprising a positive electrode, a negative electrode, and a non-aqueous electrolyte, wherein the positive electrode comprises a positive electrode material layer, with the positive electrode material layer having a compaction density of 2.3 to 2.8 g/cc and comprising a positive electrode active material, which contains LiFePO4; and the non-aqueous electrolyte comprises a solvent, an electrolyte salt, vinylene carbonate, and a compound as represented by structural formula 1: A-D-B-E-C structural formula 1 with the addition amount of the compound as represented by structural formula 1 being 0.01% to 5% on the basis of the total mass of the non-aqueous electrolyte being 100%. The lithium iron phosphate battery provided by the present invention involves the use of the combination of vinylene carbonate and the compound as represented by structural formula 1. The combination can inhibit the generation of lithium dendrites at a negative electrode interface and the dissolution of Fe at the positive electrode, and ultimately improves the performance of a high-compaction-density lithium iron phosphate battery in terms of high-temperature, safety, etc. |
