With the continuous development of lithium battery industry, more and more products are used in lithium battery products. Compared with lithium ion battery, lithium iron phosphate battery is better. The difference mainly lies in composition source, safety and cost. Therefore, domestic new energy vehicle enterprises mostly used lithium iron phosphate batteries as energy sources in the early stage.
Lithium battery is a kind of lithium battery with lithium iron phosphate battery as the cathode material. The key cathode materials of lithium battery are lithium cobalt acid battery, lithium manganese acid battery, lithium nickel acid, ternary material, lithium iron phosphate battery and so on.
Compared with Ni-H and NI-CD rechargeable batteries, lithium iron phosphate batteries have great advantages.
Lithium battery is made of lithium metal material or lithium aluminum alloy as battery cathode material in non-hydraulic power solution. The physical properties of lithium metal materials are very bright, so there are strict regulations on their production, processing, storage, application and ecological environment protection.
When the overcharge resistance of lithium iron phosphate battery reaches 100%, it is not prone to explosion accident; When the lithium battery reaches a certain standard value, it will produce vapor body for precipitation.
Lithium battery is a single typical working voltage of lithium iron phosphate battery. There will be no explosion without fire during the puncture, and there will be no explosion of lithium batteries.
Lithium iron phosphate battery is resistant to overcharge and overdischarge, which can repair over 80% of the characteristics in a short period of time. Overexposure of lithium batteries can cause irreversible damage.
Lithium iron phosphate batteries can charge and discharge at a large current, exceeding 10C~20C, while lithium batteries only charge and discharge at 3~4C.
However, 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-discharge characteristics, it has a key application in pure electric vehicles, aviation models and other levels. And the large volume of lithium battery, the key to civilian industry.
Lithium iron phosphate battery (LiFePO4) as battery cathode material, using copper as rechargeable battery raw material, not only reduce the cost, but also improve the safety factor. The P-O bond in the crystallization of lithium iron phosphate battery is very smooth and not easy to dissolve. Even under high temperature or overcharge standard, it will not cause hot or structural collapse, so it can be trusted.
