Introduction to the structure and repair method of iron lithium ion battery
Iron-lithium ion battery structure: The structure of iron-lithium ion battery relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ drags and intercalates between the two electrodes to cause discharge. The cathode material is generally used Lithium manganese oxide, lithium cobalt oxide, lithium nickel cobalt manganese oxide (ternary material), lithium iron phosphate, etc., are basically breakthrough materials with better chemical properties, so they have excellent discharge performance, coupled with later leakage protection, and prevent Overcharge and overdischarge, etc., make lithium-ion batteries more advantageous. At present, the energy density of relatively hot lithium-ion batteries is about 100-150Wh/kg, and the general battery charge can reach 1C. This data is obviously much higher than that of lead-acid batteries. In addition, the use of lithium-ion batteries will not pollute the human body and the environment. Lithium iron battery repair method (1) Regrouping: After the entire set of lithium iron phosphate batteries is damaged, we often perform charge and discharge tests on the lithium ion battery pack of electric vehicles. During the inspection, it is often found that there are 50 batteries in a set of batteries. % Of the batteries are not damaged. The reason is that in the series-connected battery pack, individual batteries lag behind, resulting in a decline in the function of the entire battery pack, so that the function of the entire battery pack is reduced. (2) Replenishing water: Replenishing the lithium-ion battery used for about 4 months can prolong the service life of the battery by an average of more than 3 months. It should be noted that after each replenishment of water, the battery is in an overcharged state to turn the battery from a quasi-lean liquid to a lean-liquid state, and this overcharge is beneficial to increase the battery capacity. (3) Eliminate sulfide: use iron phosphate lithium ion battery repair equipment to eliminate sulfide on the battery.
