| titleOfInvention | A kind of storage and activation method of lithium iron phosphate battery |
| abstract | The invention provides a storage and activation method of a lithium iron phosphate battery, wherein the positive active material of the lithium iron phosphate battery comprises lithium iron phosphate or modified lithium iron phosphate accounting for more than 85% of the total mass of the active material; the battery The electrolyte includes dimethyl sulfoxide and butyl methanesulfonate as additives; the first predetermined voltage is lower than the second predetermined voltage, and the first predetermined voltage is 3.35-3.44V; the second predetermined voltage The voltage is 3.40‑3.45V; the battery is stored for a period of time, the battery is pulse charged to the second predetermined voltage, then discharged with constant current to the discharge cut-off voltage, then charged with constant current to the second predetermined voltage, and charged with the second predetermined voltage and constant voltage, Until the current is lower than the cut-off current, and then constant current charge to the charge cut-off voltage. The lithium iron phosphate battery subjected to the present method can be stored for a long time and can substantially maintain the capacity before storage after storage. |
