| titleOfInvention | Preparation method of electrolyte for lithium ion power battery |
| abstract | The invention discloses a preparation method of electrolyte for a lithium ion power battery, and particularly relates to a preparation method of non-aqueous electrolyte for the lithium ion power battery. The method comprises the steps of firstly adding more than two non-aqueous solvents into an electrolyte preparation kettle, controlling the temperature and the pressure of materials, starting stirring, and adding electrolyte lithium salt LiPF according to the proportion requirement 6 Dissolving and mixing; then adding a small amount of other lithium salt (Li) into the electrolyte preparation kettle 3 PO 4 、Li 2 HPO 4 ) Heating, stirring, dissolving, and vacuum treating; and finally, filtering the electrolyte into another preparation kettle, adding other functional additives in proportion, mixing and dissolving, and filtering to obtain a qualified product. The method is simple to operate and can inhibit LiPF 6 High-temperature decomposition and improvement of the high-temperature performance of the electrolyte; and the cost of the used raw materials is low, so that the method has high market application and popularization values. |
