Alkegen has begun commercial production of its silicon fiber anode material platform, SiFAB. The company’s new SiFAB production line is an extension of its established large-scale manufacturing facility in New Carlisle, Indiana.

SiFAB features micron-sized silicon fiber with an engineered structure that enables higher energy density through a nanoporous fiber structure that accommodates swelling. SiFAB is a drop-in solution for existing electrode formulations and mixing equipment; it can be mixed into anode slurry with existing battery manufacturing processes.

SiFAB is currently being validated by customers for use in more than 20 different applications, according to Chief Innovation Officer Chad Cannan.

Multi-batch samples of SiFAB are available for qualification now.
