The fiber-based materials solution supplier Ahlstrom-Munksjö Oy, Helsinki/Finland, advances further into the energy storage market by signing a marketing license with Soteria Battery Innovation Group (BIG), Greenville, SC/USA, allowing the company to proceed with the technical ramp-up to manufacture fiber-based separator solutions to the lithium-ion battery industry. The agreement is an important step in the commercialization of Ahlstrom-Munksjö’s solutions to the energy storage market.
Demand for energy storage is expected to grow significantly in the coming years, driven by vehicle electrification, a shift towards renewable energy, an increasing demand in stationary applications and effective electricity supply chain management. Fiber-based materials are widely used in energy storage devices and thanks to its expertise in cellulose, micro-glass and specialty nonwovens, Ahlstrom-Munksjö is developing a complete range of solutions to its customers under the FortiCell product platform.
BIG is an industry consortium dedicated to enabling portable electric power without the risk of fires. The Soteria BIG architecture uses thermally stable separators made from advanced fibers and combining them with current collectors that are engineered to be unstable under the big current densities associated with internal shorts. The architecture will provide the same electrical protection as a fuse on the inside of each battery.
