3.7V 18650 lifepo4 battery

　　The difference between polymer 3.7V 18650 lifepo4 battery and ternary 3.7V 18650 lifepo4 battery

　　The positive electrode material of polymer 3.7V 18650 lifepo4 battery can be divided into lithium cobalt oxide, lithium iron phosphate, ternary material and lithium iron phosphate battery raw material. The negative stage is graphite material, and the principle of battery operation is roughly the same. The main difference between the negative electrode materials of polymer lithium batteries is the difference in electrolyte solutions. Liquid lithium-ion batteries use liquid electrolyte solutions, while polymer lithium-ion batteries use solid polymer electrolyte solutions instead. This type of polymer can be dry. , can also be colloidal, and at present most use polymer gel electrolyte solutions.

　　Ternary polymer 3.7V 18650 lifepo4 battery cathode materials are used in lithium-ion batteries or lithium-ion batteries. Ternary composite anode materials are nickel salts, cobalt salts and manganese salts. The proportion of nickel, cobalt and manganese in lithium-ion rechargeable batteries can be adjusted according to actual needs. Ternary materials are higher than lithium-ion batteries. Among them, lithium phosphate battery is used as the cathode material for battery charging, and the charging cycle is all normal. However, its disadvantages are that there are great differences in electric energy, high temperature and low temperature performance indicators, and battery charging performance. The cost is higher, and the new lithium phosphate battery has shortcomings in use. There is a development trend; lithium phosphate batteries have low power and high manganese batteries have weak reliability and storage performance indicators. Therefore, lithium phosphate is only the cathode material of the world's first generation of power lithium-ion batteries; its comprehensive functions and core competitive costs are increasingly becoming manufacturing The industry's attention and understanding gradually surpassed lithium iron phosphate batteries and lithium iron phosphate ion batteries to become a key technology in the manufacturing industry.

　　Advantages of polymer lithium batteries

　　1. The service life of all normal circulation systems in normal use should exceed 500 times.

　　2. There is no need to clear the remaining power before recharging the battery.

　　3. Good safety factor: The characteristics of the polymer lithium ion structure are different from the plastic shell of the liquid lithium ion core. It has the characteristics of soft packaging. If a safety hazard occurs, the liquid lithium ion core is easy to explode, and the polymer battery core will explode at most.

　　Advantages of ternary lithium batteries

　　1. All normal circulatory systems have higher frequencies and become safer. At present, the cost of ordinary circulation systems is as high as 1,500 times. The safety factor of lithium batteries of ternary materials is constantly improving, and is closer to that of lithium phosphate batteries. In recent years, although the new Ni-Co-Al ternary materials have higher requirements on the natural environment during the production and manufacturing of rechargeable batteries, the reliability and safety of the materials have been improved.

　　2. Ternary lithium-ion battery has high voltage power and high specific power. The working standard voltage platform of ternary materials is higher than that of lithium iron phosphate batteries.
