Samsung SDI achieves breakthrough in lithium metal batteries and may launch commercial solutions in the future

Glonghui, February 23｜Korean battery manufacturer Samsung SDI announced that the company has made a breakthrough in extending the lifespan and improving the safety of lithium metal batteries, which may pave the way for the commercialization of its next-generation products. Samsung SDI stated that, in collaboration with Columbia University, the company has jointly developed a fluorine-based gel polymer electrolyte that can effectively suppress the formation of dendrites—a key factor that has long impaired the performance of lithium metal batteries. Among existing battery technologies, lithium metal batteries have the highest energy density, more than 1.6 times that of traditional NCA lithium-ion batteries. However, due to their short charge-discharge lifespan (usually only dozens of cycles), their commercialization process has been hindered.
