Ahlstrom-Munksjö signs licensing deal with Soteria for fibre-based lithium-ion battery separators

by John Shepherd
Ahlstrom-Munksjö said today it has signed a marketing licence agreement with the Soteria Battery Innovation Group (BIG) – boosting the company’s technical ramp-up of manufacturing fibre-based separators for the lithium-ion battery industry.

Finland-headquartered Ahlstrom-Munksjö said the deal was an important step in the commercialisation of its products to benefit the global energy storage market.

Bertrand Rupin, head of energy storage business development, said the "milestone partnership demonstrates our confidence in our ability to supply the lithium-ion battery market with a safe and efficient fibre-based separator”.

Soteria BIG is dedicated to enabling portable electronic power products without the risk of fires. The consortium’s material architecture, which comprises thermally-stable separators made from advanced fibres, "eliminates the spark on the inside of a battery that can cause fires”.

'Enhanced battery safety'

Brian Morin, CEO at Soteria BIG, said: "We are very excited to welcome Ahlstrom-Munksjö as a licensee, and look forward to helping them use their global reach and unique capabilities to bring products to the market, using Dreamweaver separator technology to enhance lithium-ion battery safety.”

Fibre-based materials are widely used in energy storage devices and Ahlstrom-Munksjö is harnessing its expertise in cellulose, microglass and speciality non-woven materials in developing a range of products for its FortiCell portfolio.

The FortiCell range, launched last September, includes a variety of AGM battery separators, pasting papers and glass and non-woven solutions.
