With the continuous development of lithium industry, more and more products are used in lithium battery products. Lithium iron phosphate battery is better than lithium ion battery. The difference is mainly the source of composition, safety and cost. Therefore, the domestic new energy vehicle enterprises, early mostly use lithium iron phosphate battery as the energy source.
Lithium battery is a kind of lithium battery with lithium iron phosphate battery as cathode material. The key cathode materials of lithium battery are lithium cobalt acid battery, lithium manganese acid battery, lithium nickel acid, ternary materials, lithium iron phosphate battery and so on.
Lithium iron phosphate battery of secondary battery, the key development prospect at the present stage is lithium battery, which has great advantages compared with NI-H and NI-CD rechargeable batteries.
Lithium battery is made of lithium metal material or lithium aluminum alloy as battery cathode material in non-hydroelectric power solution. The physical properties of lithium metal materials are very cheerful, so there are strict regulations on its production, processing, storage, application and ecological environmental protection.
When the rechargeable battery of lithium iron phosphate battery overcharges to 100%, it is not prone to explosion; When lithium battery achieves a certain standard value, vapor will be produced for precipitation.
Lithium battery is the typical operating voltage of a single lithium iron phosphate battery. There is no fire or explosion during puncture, nor will lithium batteries explode.
Lithium iron phosphate battery is resistant to overcharge and overdischarge, and can repair over 80% of the characteristics in a short period of time. Overdischarge of lithium batteries can cause irreversible damage.
Lithium iron phosphate battery can be charged and discharged at a large current, beyond 10C~20C can be charged and discharged, while lithium battery only charge and discharge 3~4C.
But the specific energy of lithium iron phosphate batteries is not as high as that of lithium batteries. The operating voltage difference is smaller. Because of its large charge and discharge characteristics, it has key applications in pure electric vehicles, aviation models and other levels. The lithium battery with large volume is the key to the civil industry.
Lithium iron phosphate battery (LiFePO4) is used as the cathode material of battery, and copper element is used as the raw material of rechargeable battery, which not only reduces the cost, but also improves the safety factor. The P-O bond in the crystal of lithium iron phosphate battery is very stable, not easily dissolved, and will not cause hot or structural collapse even under high temperature or overcharging standards, which can be trusted.
