The thermal hazard analysis of Na-ion batteries is mostly focused on the material level. Zhao et al. found that desodiated Na x Fe 1/3 Mn 2/3 O 2 cathode materials released more heat than Li 0.5 CoO 2 (LCO), but the onset temperature of the exothermic reaction exceeded 330 °C, which was higher than that of LCO with 190 °C.
While there is not a specific OSHA standard for lithium-ion batteries, many of the OSHA general industry standards may apply, as well as the General Duty Clause (Section 5(a)(1) of the Occupational Safety and Health Act of 1970). These include, but are not limited to the following standards:
Lithium-ion batteries contain various components that present different chemical hazards to workers, such as lammability, toxicity, corrosivity, and reactivity hazards. These chemicals may enter the workplace as raw materials or recycled materials.
However, as the demand for energy density in BESS rises, large-capacity batteries of 280–320 Ah are widely used, heightens the risk of thermal runaway (TR) [6, 7].
Battery energy storage systems (BESS) represent pivotal technologies facilitating energy transformation, extensively employed across power supply, grid, and user domains, which can realize the decoupling between power generation and electricity consumption in the power system, thereby enhancing the efficiency of renewable energy utilization [2, 3].
