It is important to keep a fire risk caused by external shocks in the solid-state battery at nearly zero as the all solid battery can be used not only in EVs but also ships, drones and urban air mobility vehicles.“Enhancing the safety of exterior materials is critical in solid-state batteries,” Samsung SDI’s Executive Vice President Go Joo-young said during the first SNE Battery Day held in Seoul, Korea on Wednesday.“Pouch cells are vulnerable to fire” because its exterior material is film, added.Go.
The solid-state battery is considered a promising solution to address the limitations of traditional lithium-ion batteries such as a fire risk and limited range, and many battery manufacturers are rushing to produce them to revolutionize industries ranging from electric vehicles to renewable energy systems.
POUCH CELLS FOR HIGHER ENERGY EFFICIENCYHowever, LG Energy Solution expects pouch-type solid-state batteries to be better at achieving higher energy efficiency than existing liquid electrolyte batteries because it is easier to increase pressure inside the pouch cell to facilitate ion transfers further.
