  1. Life life

  The number of lithium iron phosphate batteries will start attenuation after about 3500 times, and its service life can be up to ten years, but the number of three -yuan lithium battery charging discharge cycle is only 2000 times, which means that its service life is only 6 years. Essence

  Second, safety performance

  Lithium iron phosphate batteries and ternary lithium batteries will decompose when they reach a certain temperature. The decomposition temperature of the former is higher than the ternary lithium battery (about 200 ° C for the ternary material, and the lithium phosphate battery is about 800 ° C). In contrast, lithium iron phosphate batteries have higher adaptability to temperature.

  However, as manufacturers have been strengthened in the intensity of over -charging protection, over -protection, overcurrent protection, and over temperature protection, they can work in a safe state and reduce hidden safety hazards in a safe state.

  Third, cost

  Since lithium iron phosphate batteries do not contain valuable metal materials, the cost of raw materials can be appropriately compressed. The ternary lithium battery uses the lithium nickel cobalt lithium as the positive electrode material and graphite as the negative electrode material. Among them, the cobalt element has less reserves in my country. A lot more expensive.

  Compared with the traditional iron phosphate, the ternary positive material has a higher ratio capacity, which can greatly increase the energy density of the battery, thereby supporting the needs of end products such as new energy vehicles for "high battery life" capabilities.

  In general, the ternary lithium battery has great advantages in terms of high -rate charging and low temperature resistance.
