Glatfelter and DreamWeaver International partner to develop and manufacture lithium-ion battery separators

12 March 2013

DreamWeaver International and P.H. Glatfelter Company formed a partnership to develop and manufacture next-generation high performance and affordable separators targeted for energy storage devices such as lithium-ion batteries and ultracapacitors.

DreamWeaver battery separators combine microfibers and nanofibers in a porous substrate. DreamWeaver Silver is a general-purpose product with excellent power capability and DreamWeaver Gold has very high temperature stability (up to 300 °C) without significant thermal shrinkage. Glatfelter is a world leader and global supplier of fiber-based engineered materials for consumer and industrial applications.

The partnership will focus on developing and manufacturing the current generation of DreamWeaver products and jointly developing future generations.

DreamWeaver will be able to leverage Glatfelter’s inclined wire capabilities and expertise in making advanced fiber-based engineered materials. Glatfelter continues to optimize the use of its eight inclined-wire machines to produce a diverse range of products, including non-woven energy storage materials for the capacitor and lead-acid battery markets. These new fiber-based materials possess superior porosity and excellent web uniformity in low basis weight and thickness.
