According to foreign media reports, Samsung SDI company of South Korea recently announced that its lithium products have passed ul9540a fixed energy storage system (SS) safety installation test certification, and its test is mainly aimed at the fire hazard caused by thermal runaway. It is understood that UL 9540a, the safety certification agency, issued in 2018 the UL 9540a standard entitled "test method for evaluating the spread of heat runaway fire in battery energy storage system", to find a way for energy storage manufacturers to prove that their products conform to the new regulations, including the introduction of NFPA standards, as well as the current international fire protection regulations (2018) IFC). For example, compliance with ul9540a can make the installation distance of battery energy storage system rack more compact and secure than that of NFPA 855 standard. According to a Samsung SDI survey, meeting the test standards means that battery racks can be installed without the need for a separate fire protection system. The company said it has the ability to prevent a fire in a battery storage system by adopting a proprietary design that prevents the uncontrolled spread of battery heat in terms of the safety of batteries, modules and racks. Since August 2017, there have been 27 ess fire accidents in South Korea, including 17 lithium batteries produced by LG Chemical and 9 lithium batteries produced by Samsung SDI. In order to remedy the compensation and loss caused by the safety risk of energy storage battery, Samsung SDI is trying to "mend the situation without delay". Recently, Samsung SDI demonstrated a new solution to prevent the fire of energy storage system at its Ulsan battery factory, and announced that it would spend 200 billion won (1.208 billion yuan) to improve the safety of its ess. Samsung SDI added blockers to the new battery module. The orange blocker, which contains two special chemicals, is a part of its special fire extinguishing system, which can prevent the fire after the electric core is damaged. In addition, Samsung SDI is also developing software solutions and required devices to monitor and detect the wrong operation of the units in the ESS module. However, Samsung believes that a series of ESS fire accidents have nothing to do with its electric core, so the safety plan developed does not involve the electric core. However, the energy storage batteries of Samsung and LG Chemical belong to ternary batteries. Compared with the commonly used lithium iron phosphate batteries in China, the safety risk is significantly higher. LG Chemical's energy storage cell has been found to have safety defects in the investigation. Samsung SDI's cell survived?
