What are the advantages and disadvantages of lithium battery pack and ternary lithium battery?

1. The advantages of lithium battery packs have good high temperature function: the peak heat of lithium iron phosphate battery packs can reach 350℃-500℃, and the operating temperature range is wide -20C-75C. Long service life: Lithium iron phosphate power lithium-ion battery has a cycle life of more than 2000 times, and the standard charge rate of 5 hours can reach 2000 times. large capacity. The storage capacity of lithium iron phosphate battery pack is 2 to 3 times higher than that of carbonic acid battery under the same volume. 2. Disadvantages of lithium battery packs The cost of preparing materials and battery manufacturing is higher, and the yield of the battery is low, which will make the cost of the unit energy storage capacity higher in the end. The low temperature function of the lithium battery pack is poor, and the tap density of the positive electrode material is small. The lithium iron phosphate battery cannot drive the electric vehicle at low temperature (below 0°C), and the density is generally about 0.8 to 1.3. The product consistency is poor. At present, there is no lithium iron phosphate material factory in China that can solve this problem. In this complex response process, it is difficult to ensure the consistency of the response. The conductivity is poor, the diffusion rate of lithium ions is slow, and the actual specific capacity is low when charging and discharging at high times. ■Analysis of the advantages and disadvantages of ternary lithium batteries 1. The advantages of ternary lithium batteries have high voltage channels: the voltage channels of ternary materials are significantly higher than lithium iron phosphate, the high line can reach 4.2 volts, and the discharge channel can reach 3.6 or 3.7 volts. High energy density: the higher the voltage channel, the larger the specific capacity, so the battery with the same volume, weight, or even the same ampere hour, the ternary material lithium battery with higher voltage channel has a longer battery life. 2. The shortcomings of ternary lithium batteries have poor safety functions. It is difficult for ternary batteries with larger capacity to pass safety tests such as acupuncture and overcharge. Poor high temperature resistance, unstable high-temperature structure, resulting in poor high-temperature safety, and excessively high pH easily causes monomer flatulence.
