　　Advantages and Disadvantages of 18650 battery 3.7v 3500mah Phosphate Batteries

　　18650 battery 3.7v 3500mah phosphate battery

　　18650 battery 3.7v 3500mah phosphate battery: refers to a lithium-ion battery using 18650 battery 3.7v 3500mah phosphate as the positive electrode material of the battery. Its characteristics are that it does not contain precious metals such as cobalt, the raw materials are cheap, and the earth's resources of phosphorus and iron are rich in composition, so there is no difficulty in supplying materials. It has moderate working conditions, large capacity per unit weight (170mah/g), high discharge power rating, fast charging, long life, and high reliability in high-temperature and hot natural environments.

　　Advantage:

　　Compared with lithium cobaltate and lithium manganese oxide batteries, 18650 battery 3.7v 3500mah phosphate batteries have the following five advantages: high safety factor, long service life, no heavy metals exceeding standards, non-ferrous metals (low raw material cost), fast charging, and wide operating temperature range .

　　defect:

　　18650 battery 3.7v 3500mah phosphate batteries have shortcomings such as low vibration density and low compaction relative density, resulting in low specific energy of lithium batteries; high raw material manufacturing and rechargeable battery manufacturing costs, low rechargeable battery productivity, and poor product consistency; patent issues.

　　2. Ternary lithium battery

　　Ternary polymer lithium-ion battery: Lithium-ion battery uses nickel cobalt (nicomn) O2 ternary battery. According to Ouyang Minggao of Tsinghua University, the ternary raw material, usually mentioned in this study, is a three-dimensional and high-purity graphite, commonly known as a three-dimensional power lithium battery. In specific product research and development, there are also three-dimensional, negative lithium titanate, generally called lithium titanate, which has safer properties and a long service life, and is not called a ternary material.

　　Which is the best battery between lithium phosphate battery and lithium ion battery? Comparison of advantages and disadvantages

　　Advantage:

　　Ternary lithium-ion batteries have higher energy than ordinary lithium cobalt oxide batteries. At present, with the continuous improvement of sealing formulas and sound structures, the nominal voltage of rechargeable batteries has reached and the volume has reached or exceeded the level of lithium cobalt oxide batteries.

　　defect:

　　Due to the unstable high-temperature structure of ni-co-al, ni-co-al has a poor high-temperature safety factor and the pH value is too high to cause abdominal distension, thus posing risks.

　　Summary: In comparison, ternary polymer lithium batteries do have better characteristics than lithium-ion batteries, but the development trend of new energy technology at this stage has been hindered, but overall, it is more powerful.
