Lithium iron phosphate battery is a battery based on lithium iron phosphate. The chemical properties of lithium iron phosphate are very stable. In practical applications, fever and explosion will not occur due to expired charging or high temperature. Lead -acid batteries can only use 500 times, while lithium iron phosphate batteries can be used more than 2000 times, which is much better than lead -acid batteries.

　　Data show that the battery has a 7 -year service life. Lithium iron phosphate ion battery has a wide working temperature, and its maximum electric heating can reach 350 ~ 500 degrees Celsius. Compared with conventional lead -acid batteries, its storage capacity is much larger, and its weight is relatively lighter, which can maintain a relatively stable attenuation speed throughout the life cycle. But if it is in the south, it is even better.

　　The theoretical life of lithium iron phosphate is also more than 2000 times. The charging once a day can last more than 5 years. Under normal circumstances, charging once every three days can be used for about eight years. However, because of the low temperature characteristics of lithium iron phosphate, its service life in the south is longer than other places.

　　Second, aluminum shell

　　Aluminum shell is a battery shell made of aluminum alloy, which is mainly used for lithium ion batteries, and the reason why lithium batteries choose aluminum shells is because of its weight and safety. There are two types of aluminum shells. The aluminum shell is mainly composed of MN, CU, MG, SI, FE, etc. These alloy play a great role in the aluminum shells of lithium ion batteries. For example, copper and magnesium can increase Hardness and manganese can increase corrosion resistance and silicon can enhance the heat resistance of magnesium aluminum alloy, and iron can increase the high temperature strength of aluminum.

　　The aluminum shell alloy structure has obvious safety, and its safety available material thickness and expansion coefficients are expressed. The same volume of iron oxygen is lighter than iron, which is why the aluminum shell can become thinner.
