Explore new business models. 2, Parts and companies include: State Grid, Beijing Crafts, Beijing Pleide and Beiqi, my country Tower, Shenzhen BYD, Guoxuan High ", Wuxi Greenmei and SF Company, Zhongtianhong lithium; involving the field contained: energy storage field, Base station preparation, urban logistics car, sanitation, sightseeing and other vehicle applications.

The National Grid has built a 100KWH ladder in Beijing, the use of a lithium-ferrous ion battery energy storage system demonstration, and the 1MWH ladder is used to use the phosphate ion battery energy storage system demonstration. At the same time, the decommissioning battery sorting assessment technology platform has been established, and the technical specifications of the battery or reliable battery management system have been developed. Beijing constructed core developed the ladder using the optical storage system, and is building a powerful battery pack based on big data (group) evaluation system.

Beijing Pleide and Beiqi and other cooperation have implemented energy storage power station projects, container storage projects, etc., accumulated ladder use of about 75MWH. my country Tower Company conducts a ladder by about 120,000 base stations in 31 provinces and cities across the country.

The use of the ladder is approximately 1.5GWH. The current operation is good, fully verified the safety and technical economic feasibility of the ladder.

At the same time, my country's Tower Company led the leading through a group of ladder utilization key technologies such as battery-made group and capacity comprehensive assessment. Shenzhen BYD, Guoxuan High-class company uses the retired power storage battery, producing a tradder using battery products in the field of preparation. Wuxi Greenmei and SF Company explored the use of batteries for urban logistics vehicles, Zhongtianhong, etc.

3, the Ministry of Industry and Information Technology realizes the traceability information supervision of the ladder using the company;. 4, the ladder is in the starting stage, the problem is that the key technology of battery remaining life and consistency assessment, etc., the bottleneck needs to be broken, management mechanism and business model should further explore.

Second, the dynamic lithium battery regeneration is initially applied to the scale 1, announce the implementation of the "New Energy Automobile Waste Battery Battery Comprehensive Utilization Industry Standard Conditions" and the Management Interim Measures, and actively cultivate the industrial backbone company, support the company to develop renewable use technology and technology. 2, Parts and companies include: Hubei Greenmei, Hunan Bangpu, Zhejiang Huayou Cobalt Industry, Guangdong Guanghua, Beijing Saidmy, Jiangxi Hapeng; related companies conducted process development, production line construction, etc. according to its own technology.

Hubei Greenmei Company built a waste-lossless unmoving line of waste-like power storage, developed "liquid phase synthesis and high temperature synthesis" process, produced spherical cobalt powder can be used directly in battery positive material production. Hunan Bangpu has developed a dynamic battery module and monomer automation dismantling equipment, and the development of "orientation cycle and reverse product positioning" process can produce lithium nickel-cobalt-manganese acid and battery-grade tetrashydoxide. Zhejiang Huayou cobalt industry construction waste lithium-ion battery resource recycling recycling circulation utilization production line, with battery pack (group) dismantling treatment, monomer crushing grading, wet purification and other processing processes.

Guangdong Guanghua Company has built a regenerative utilization production line, and has developed a "multi-stage series of complexed extraction purification", "bipolar membrane electrodialysis" and other technologies, using environmentally friendly treatment technology to achieve multiple viable metal elements recycling. Beijing Saidmi company has developed an electrolyte and diaphragm dismantling recovery process, and the shell, electrolyte, diaphragm, positive waste powder, negative powder, and other materials can be dismantled, and then the material repair process is positive and negative. Extreme material.

Jiangxi Hao Peng has put into operations with lithium-ion battery recycling projects, with perfect waste battery harmless treatment equipment and processes, using advanced environmental technology and equipment to resource treatment for waste batteries. 3, waste power storage battery regeneration use technology with wet metallurgy and physical restoration method, wet metallurgical nickel, cobalt, manganese and other metal elements can reach 98%. 4, in general, renewable utilization technology is relatively mature, but key technologies and equipment such as high-efficiency extraction, etc.

Poor problem. Third, my country's Tower Demonstration Achievements have been significantly 1. As a state-owned large communication infrastructure integrated service company, it has 1.

9 million base stations. It has a big demand for the backup power supply. By promoting the recovery of retired power storage, the tradder utilization is guaranteed At the same time, the centralized utilization and control of retired power storage batteries have achieved remarkable results.

2, stop the purchase of lead-acid batteries, vigorously promote the use of lithium-ion battery. Tower Company accelerates the ladder of the base station, using demonstration promotion, 2018 has stopped purchasing lead-acid batteries, unified procurement ladder. As of the end of 2018, approximately 1.

5GWH of approximately 1.5GWh in 31 provinces and cities across the country, replacing approximately 45,000 tons of lead-acid batteries. Tie Tower and my country FAW, SAIC Group and other 11 automobile production companies cooperation planning to build recycling channels, and take the lead in Shanghai, Hubei, Guangdong, etc.

Centralized recycling and harmless disposal of batteries. At the same time, cooperation with my country Post, Commercial Bank, Guo Net Electric Vehicle and other companies and other companies use battery applications in the computer room alternate power supply, power grid peaks, new energy power generation and electricity dynamic expansion, etc., and is building in Hexi, Hedong, Gansu Province 15MWH photovoltaic elevator secondary use of projects, 10MWH wind power generation ladder utilization test project, improve the comprehensive efficiency of the ladder.

According to Tower Company Planning, in 2019, it will continue to expand the ladder using the battery to use the battery. It is expected to use the battery about 5GWH, replace the lead-acid battery about 150,000 tons, and it is expected that the energy storage battery exceeds 50,000 tons. In the 17 provinces and cities construction, 150 recycling service outlets, and develop a number of application models, breakthroughs of residual evaluation, rapid testing, etc.

3, the iron tower company has a problem of vigorously promoting the driving battery ladder, and there are still some problems. It is important to have fewer retired batteries. The industrial chain downstream company competes for limited retired battery resources, and the ladder is not high.

At the same time, the industry also has bottlenecks in terms of technical aspects such as residual evaluation, and information such as historical data used in power storage batteries is used to evaluate the performance of retired power storage battery to ensure the safety and reliable use of battery products.
