What are the advantages of the retired lithium-ion power lithium battery echelon utilization?

At present, there is limited room for improvement in performance and cost of lithium iron phosphate lithium-ion power lithium batteries, so lithium iron phosphate lithium-ion power lithium batteries will be more suitable and ahead of the tiered utilization of ternary materials lithium-ion power lithium batteries in the energy storage industry. Comprehensively considering the use conditions of energy storage equipment, the power lithium battery after retirement can continue to be used as an energy storage battery for at least five years. It can give full play to the remaining value of retired power lithium batteries, maximize the circular economy, and reduce the construction cost of energy storage systems. The characteristics of retired power lithium batteries are as follows: 1) Due to the differences in the individual use habits of new energy vehicle users and the differences in the regional use environment (temperature, etc.), the attenuation of power lithium batteries in each pallet is different, even if it is the same from the same manufacturer. Batch of power lithium batteries. 2) The power lithium battery not only has a service life, but also has a calendar life. The service life of the retired power lithium battery will not be too long, and many power lithium batteries even die without a disease and fail instantly. 3) The traceability of decommissioned power lithium battery parameters is generally poor, and it is difficult to accurately evaluate the reuse life (number of charge and discharge). 4) The price is cheap or even zero. 5) Because it is a retired power lithium battery, there is generally no warranty or a short warranty period (usually no more than two years). The technological advancement and performance improvement of power lithium batteries are conducive to the echelon utilization of power lithium batteries, and the related standardization of power lithium batteries for electric vehicles also contributes to the echelon utilization. At present, the entire industry standards and technical system need to be improved, and domestic PACK and BMS technologies can be more closely integrated with power lithium batteries. Vehicle manufacturers have increasingly higher requirements for BMS technology and power lithium battery management technology. It is an objective demand for the market to improve and upgrade the technical level. The closer the company is to integrate the retired power lithium battery echelon utilization company with car companies, the more it can adapt to market needs. Retired lithium-ion power lithium batteries have the following advantages relative to traditional lead-acid power lithium batteries: 1) The self-discharge rate of lithium-ion power lithium batteries used in cascades is low, and the number of cycles is large. It can still have an actual life of 6 years, with more than 400 deep cycles, which is a significant increase compared to the 5-year service life of traditional lead-acid batteries, which is about 100 deep cycles. 2) High temperature resistance, lithium-ion power lithium battery can meet the use environment of -5～45℃. At present, the upper temperature limit of lead-acid power lithium battery commonly used in communication base stations is only 30℃. 3) Good discharge characteristics, large current discharge. 4) The self-discharge efficiency is low, which can reduce the power loss of long-term floating charge of the power lithium battery. 5) Small footprint, light weight and low transportation cost. The weight and volume of lithium-ion power lithium batteries are 1/2 to 2/3 of the same capacity lead-acid power lithium batteries.
