## Innovative Steel Foils for Next-Generation Batteries Solum Advanced Materials has made a significant step in the battery sector by developing ultrathin stainless steel foils designed for all-solid-state batteries. These batteries represent a promising alternative to traditional lithium-ion batteries, potentially offering greater safety, energy density, and lifespan. All-solid-state batteries, unlike their lithium-ion counterparts, use a solid electrolyte instead of a liquid one. This eliminates the risk of leaks and fires, making them inherently safer. Furthermore, the higher theoretical energy density of all-solid-state batteries could lead to electric vehicles with greater range and faster charging times. The development of materials like Solum's foils is crucial for the commercialization of this technology.
