　　Which is better, lithium iron phosphate battery or lithium titanate battery

　　Which is better, lithium titanate battery or lithium iron phosphate battery pack? As far as power batteries are concerned, ternary lithium batteries, lithium iron phosphate battery packs and lithium titanate batteries are now used in electric vehicles. Lithium iron phosphate battery is more and more active in the electric bus market because of its stable safety function, good high-temperature function, light weight and other advantages. So, which is better, lithium titanate battery or lithium iron phosphate battery pack? This article has compiled some materials for you to read.

　　Comparison of lithium titanate battery and lithium iron phosphate battery pack:

　　Lithium titanate battery:

　　Lithium titanate battery is a kind of lithium ion secondary battery used as cathode material of lithium ion battery - lithium titanate, which can form 2.4V or 1.9V with lithium manganate, ternary material or lithium iron phosphate and other cathode materials. In addition, it can also be used as a positive pole to form a 1.5V lithium secondary battery with metal lithium or lithium alloy negative pole. The common lithium titanate battery is prone to gas expansion, leading to cell bulge, and the electrical function will also be greatly reduced, greatly reducing the theoretical cycle life of the lithium titanate battery.

　　Advantages of lithium titanate battery:

　　1. Good safety and stability

　　The potential of lithium titanate is higher than that of pure lithium metal. It is not easy to produce lithium dendrites, and the discharge voltage is stable. Moreover, the safety function of lithium battery is improved. The test of lithium titanate battery shows that under harsh tests such as acupuncture, kneading and short circuit, it does not smoke, fire or explode, and its safety is much higher than other lithium batteries.

　　2. Excellent fast charging function

　　Compared with the carbon negative electrode data, lithium titanate battery has higher lithium ion diffusion coefficient and can be charged and discharged at a high rate. When the charging time is greatly shortened, the cycle life is less affected, and the thermal stability is also strong. The lithium titanate battery can be filled in about ten minutes.

　　3. Long cycle life

　　The lithium titanate battery can be fully charged and discharged for more than 30000 cycles. After 10 years of use as a power battery, it may be used as an energy storage battery for another 20 years. Users do not need to replace the battery in actual use, and almost do not add later costs.

　　4. Excellent wide temperature resistance

　　The charging and discharging of ordinary electric vehicles will present problems when the temperature is below - 10 ℃. The lithium titanate battery has excellent wide temperature resistance and strong durability. It can be charged and discharged normally from - 50 ℃ to - 60 ℃. No matter in the frozen North or in the hot South, the vehicle will not be affected by the battery "shock", which eliminates the worries of users.
