Examples of industry-wide standards include the ISO/IEC standards, which provide guidelines on the manufacturing processes, testing methods, and quality assurance for battery production. Additionally, the EPA introduced the Battery Manufacturing Effluent Guidelines and Standards (40 CFR Part 461) in 1984 and changed the regulation in 1986.
During the manufacturing process, if cells get above 35 to 50 percent SOC, they must be treated as a fire hazard due to the energy density in a large number of stored cells. A manufacturing defect in a cell above 35 percent SOC, for instance, can create thermal runaway that will spread to nearby cells initiating a chain reaction.
