Soteria Licenses Rutgers Technology to Extend Lithium-Ion Battery Life
Lithium-ion batteries face a silent killer: the mechanical degradation of electrodes during charge cycles. Soteria Battery Innovation Group has moved to mitigate this by licensing a novel reticulated current collector from Rutgers University, aiming to prevent the cracking and delamination that trigger heat buildup and eventual cell failure.
Developed by a team led by Glen Amatucci, the technology replaces standard solid metal foils with a porous polymer architecture coated in thin conductive layers. This three-dimensional design offers improved flexibility and uniform current distribution, allowing the collector to maintain contact with electrodes even as they expand and contract during operation. By reducing internal resistance, the innovation directly addresses the heat generation that limits battery longevity and safety.
Soteria has integrated this patent into its Battery Safety IP Exchange, a collaborative platform that provides manufacturers with access to vetted safety technologies. Brian Morin, CEO of Soteria, noted that the Rutgers approach complements existing metallized polymer developments, offering designers a broader toolkit for next-generation cells. The exchange, managed by the company’s global consortium, seeks to consolidate research from universities and startups to accelerate the adoption of these safety-critical materials across the energy storage industry.
