Will retired lithium-ion batteries replace lead-acid batteries?

Retired lithium-ion batteries will soon replace lead-acid batteries. In front of lithium-ion 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-ion batteries. , The now-retired lithium-ion 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-ion batteries for base station backup power in a unified manner. As one of the key units of the new energy vehicle power lithium battery recycling pilot, my country's tower will be a good demonstration of large-scale cascade utilization of retired power lithium-ion 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-ion 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 decommissioned lithium-ion batteries. After years of testing, it has been proved that the safety, technical economy, and economy of decommissioning lithium-ion 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-ion 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-ion batteries in 2019 will continue to expand. 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 decommissioned power lithium-ion batteries. What is the concept of 50,000 tons of retired lithium-ion batteries? According to industry experts' comprehensive calculations from the company’s warranty period, battery cycle time, vehicle operating conditions, etc., it is expected that the cumulative scrap volume of power lithium-ion batteries in 2020 will be about 200,000 tons. In other words, the absorption capacity of our country's towers for retired lithium-ion batteries this year will have an impact on the retired power lithium-ion battery market. In fact, in the process of promotion, the cascade utilization of power lithium-ion batteries has encountered important problems. The number of retired power lithium-ion 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 purchase prices. Highly retired lithium-ion battery. In addition, the residual value and performance evaluation technology of decommissioned power lithium-ion 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-ion batteries has attracted widespread attention. Many people believe that it has broad market prospects in the field of energy storage, and the energy storage market is the best successor to retired power lithium-ion batteries. It is reported that in addition to large-scale retirements in the use of lithium-ion 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, and the power grid cuts the peak valley. Energy generation and power dynamic expansion, etc., in Hexi area of u200bu200bGansu Province, buildings use 15 MW photovoltaic pilot projects, such as wind power pilot use 10MWH pilot project statement: Some pictures and content of articles published on this site are from the Internet, if any Infringement, please contact to delete the previous article: What is the important difference between batteries and lithium-ion batteries?
