November 29, 2023: Ahlstrom-Munksjö has launched a fiber-based pasting material in a move aimed at supporting development of advanced lead batteries.

The Finland-headquartered firm said on November 9 its hybrid pasting material is a combination of natural and synthetic fibers that provide adhesion of the active material on the battery plate surface, after the natural fibre content has dissolved in the battery acid.

Ahlstrom claims this specific property stabilizes the active mass on the grid, allowing higher cycling and longer battery life, as well as easing battery recycling.

Recent advancements in lead batteries are focused on higher performance as well as on lowering the overall environmental footprint of the battery lifecycle.

The company has four manufacturing sites in Europe including an AGM line in Italy and a glass fibre tissue line in the US.

Ahlstrom said the Italian line in Turin  marked a key step into supplying products in support of expansion in the energy storage market.

In 2021, Ahlstrom signed a marketing licence agreement with Soteria Battery Innovation Group toward production of fiber-based separators for lithium ion batteries.
