Retired lithium batteries will soon replace lead-acid batteries

Retired lithium batteries will soon replace lead-acid batteries. In front of lithium batteries, how many lead-acid batteries are not defeated? In addition to the traditional digital 3C, the hot new energy vehicles in recent years have been occupied by lithium batteries. Retired lithium batteries have seized the market for lead-acid batteries. According to a report from Battery China.com, my country Tower Co., Ltd. (hereinafter referred to as my country Tower) stopped purchasing lead-acid batteries in 2018 and purchased lithium batteries for base station backup power in a unified manner. As one of the key units of the new energy vehicle power lithium-ion battery recycling pilot, my country's iron tower will be a good demonstration of large-scale cascade utilization of retired power lithium batteries. According to public information, my country Mansion is a large state-owned communications infrastructure integrated service company. It currently has more than 1.9 million communication base stations, and there is a great demand for backup power. In the past, the company purchased about 100,000 tons of lead-acid batteries each year. However, lead-acid batteries have also been criticized for their short service life, low energy density, and lead pollution. Compared with lead-acid batteries, lithium batteries have the advantages of high energy density and long service life. Since 2015, my country's Tower has started a project to replace lead-acid batteries with retired lithium batteries. After years of testing, it has been proved that the safety, technical economy, and economy of decommissioning lithium batteries on base stations are feasible. On this basis, my country's towers have accelerated the demonstration and promotion of base station cascade utilization in recent years. As of the end of 2018, 120,000 base stations in 31 provinces and cities across the country used a total of about 150 million kilowatt-hours of lithium batteries, replacing about 45,000 tons of lead-acid batteries. According to my country's tower plan, the scale of cascade utilization of decommissioned lithium batteries will continue to expand in 2019. It is estimated that the battery cascade utilization rate is about 5GWh, and the replacement of lead-acid batteries is about 150,000 tons, which can absorb more than 50,000 tons of retired power lithium batteries. What is the concept of 50,000 tons of decommissioned lithium batteries? According to industry experts, comprehensive calculations from the company’s warranty period, battery cycle time, and vehicle operating conditions, it is expected that the cumulative scrap volume of power lithium batteries in 2020 will be about 200,000 tons. In other words, the absorption capacity of our country's towers for retired lithium batteries this year will have an impact on the retired power lithium battery market. In fact, in the process of promotion, the cascade utilization of power lithium batteries and the important problems encountered, the number of retired power lithium batteries in my country's tower is very small, and the decommissioned battery resources that compete with the company's downstream industrial chain are limited, resulting in high purchase prices. Lithium battery. In addition, the residual value and performance evaluation technology of retired power lithium batteries need to be improved urgently to ensure the safety and reliability of cascaded battery products. In fact, in the past year, the phased use of retired lithium batteries has attracted widespread attention. Many people believe that it has a broad future direction in the field of energy storage, and the energy storage market is the best successor to retired power lithium batteries. It is reported that in addition to large-scale retirements using lithium batteries in communication base stations, China's towers and postal services, China's commercial banks, its electric vehicles and other companies have cooperated in researching pilots to use battery backup power in the computer room, grid peak troughs, and new energy.
