South Korea’s Samsung SDI has become the first Lithium-ion battery manufacturer to meet the safety standard for fire prevention test developed by a US certification firm, the batterymaker said on Nov. 3.

According to the company, Samsung SDI last month fulfilled the rack-level safety standard of UL 9540A’s fire prevention test for Energy Storage System. The evaluation system was developed by the US-based safety certification company UL.

 



Samsung SDI stressed it had gained UL recognitinon for its ability to prevent large-scale fire accidents in the ESS by applying its proprietary designs. They were applied in the batteries’ cells, modules, and racks to prevent their thermal runaway propagation.

“It is a result of our effort to put safety first that we were able to satisfy the UL9540A test for the first time in the industry. We are committed to developing the best in class, market-leading ESS safety technology,” said Vice president Seo Kyung-hoon of Samsung SDI Marketing Team.

Developed in April last year, the UL9540A is a test method designed to prevent ESS fires in the event of failure mode by thermal runaway. It is designed to measure the characteristics of thermal runaway and the amount of gas produced during the process, the company said.

The primary test of the UL9540A comprises a battery rack-level test and an optional battery system-level test. The racks that fulfill the rack-level test standards can be installed without installing an additional separate fire prevention system, said Samsung SDI.
