Development of a fire and explosion risk prevention mechanism for waste lithium battery storage and processing operations.

Absrtact
In view of the possible blaze or explosion risks of abandoned lithium batteries during the recycling, storage, and treatment stages, this project collected and reviewed information on lithium battery manufacturing, fire protection systems, etc. Understanding present abandoned lithium battery management regulations, and discussed at the meeting of experts and scholars, analyzed the possible blaze and explosion risks after a large number of abandoned lithium batteries possibly entering the recycling system in the future, and provide the direction of the management measures to the authorized competent unit, in order to deal with the large amount of abandoned lithium batteries after the use of energy storage systems and electric vehicles. This project collected relevant literature information to discuss the physical and chemical characteristics and possible risks of lithium-ion batteries, compiled and explained the structure and composition of lithium-ion batteries and the hazard characteristics, and also collected 3 disaster examples and studied the data of the lithium-ion batteries blast case. Secondly, widely collected other country’s abandoned lithium-ion battery management information and other related materials for compilation, including: Fire Industry Association, FIA British, National Fire Protection Association, NFPA USA, Institute of Occupational Safety and Health IOSH British, California Environmental Protection Agency CalEPA USA, Det Norske Veritas & Germanischer Lloyd, DNV GL Norway, International Airline Transport Association IATA, United Nations Recommendations on the Transport of Dangerous Goods TDG, European Union Recycling Industry Federation EuRIC and so on. In the test of lithium battery blaze disaster prevention measures, 3 field tests were carried out. According to the test results, different types of lithium batteries showed different situations when they are on blast, and the results are also divergent when using alternative fire extinguish agents, the residues of blast test study show the contents of heavy metals within these 3 residue samples were all lower than the hazardous industrial waste identification standard TCLP, and the wastewater have higher fluoride for the discharge waste water standard. In terms of recycling, storage, and treatment standard management of abandoned lithium battery, this project collects opinions from all social circles through the symposium on the management of abandoned lithium battery recycling, storage, and treatment, and combines other countries relevant information to propose suggestions for revision of facility standards, and further proposes the safety of abandoned lithium battery recycling and storage. Guidance manual, which provides references for all sectors of society to provide relevant specification content in the manual.
