[Asia Economy Reporter Choi Dae-yeol] Lee Jon-ha, Head of Battery Development Center at SK Innovation, stated, "It is possible to prevent thermal propagation (TP) even in high-density nickel products," adding, "We expect to supply battery packs to automakers by 2023."

Lee made these remarks while introducing the company's technology as a speaker at the Battery Conference, a side event of the InterBattery secondary battery exhibition. He explained that the company currently supplies battery cells or modules to automakers, and is now testing a battery pack with a uniquely designed internal structure that prevents fire from spreading to the entire pack even if a fire occurs inside a cell due to external impact. During the testing phase, thermal propagation was suppressed for about 15 minutes.

SK Innovation has emphasized that there have been no electric vehicle fire incidents involving their batteries. According to the company, the number of battery cells supplied to date is approximately 270 million, which corresponds to about 2.5 million electric vehicles.

Lee said, "Our pouch-type batteries are designed and developed based on safety from the cell, module, to pack system levels," adding, "Even when using high-density nickel cathode materials, safety is maintained while increasing driving range and enabling fast charging."
