Abstract:

Large-scale energy storage applications require high safety measurements for lithium-ion batteries. Thus, the safety detection technology of lithium-ion batteries for energy storage should be fully explored to improve the safety performance of batteries. As the first national standard for energy storage batteries in China, GB/T 36276—2018 “Lithium ion battery for electrical energy storage" estimates whether the specified safety test provisions are scientific and reasonable and whether the test methods are feasible and need to be verified. First, based on the safety accident promotion factors of lithium batteries, this study decomposes the necessary fire factors via the fire accident tree principle. Then the Boolean algebraic algorithm is used to simulate and scientifically propose the safety detection items of energy storage batteries. The results are compared and analyzed with the national standard GB/T 36276—2018, which verifies the scientific rationality of the current national standard terms. Finally, based on the test platform, 14 safety testing experiments are performed on lithium-ion batteries for energy storage in different systems, such as lithium ternary, lithium titanate, lithium iron phosphate, and lithium manganate, to verify the proposed test items. The operability and feasibility of the safety test clauses in the national standard GB/T 36276—2018 have been verified for the first time at home and abroad, providing basis and data support for revising the new version of the national standard GB/T 36276.
