en.Wedoany.com Reported - US-based Soteria Battery Innovation Group has secured a license from Rutgers University for a novel current collector technology designed to enhance the safety and durability of lithium-ion batteries.
The technology addresses a key issue in battery systems: as batteries age and repeatedly expand and contract during use, electrodes can crack and separate from the current collector.
Developed by Rutgers researcher Glen Amatucci, this innovation will be incorporated into Soteria's Battery Safety IP Exchange for broader industry licensing. As battery manufacturers pursue higher energy densities, maintaining electrode stability is increasingly critical for performance and safety.
When lithium-ion batteries undergo repeated charge-discharge cycles, electrodes expand and contract, leading to cracking and weakened contact with traditional metal foil current collectors. Over time, this increases resistance, generates excess heat, and accelerates battery degradation. To address this challenge, Amatucci's team developed a patented mesh current collector design. The technology replaces conventional solid metal foils with a lightweight porous polymer structure coated with a thin conductive metal layer, creating a more flexible architecture that better accommodates electrode expansion and contraction during repeated charging cycles.
The design is based on a three-dimensional architecture aimed at improving flexibility while reducing weight and enabling more uniform current distribution. It also helps improve electrolyte transport and limits resistance buildup and heat generation as the battery ages, addressing key factors behind performance loss and safety risks. Soteria is incorporating the technology into its Battery Safety IP Exchange, where manufacturers will access it through a collaborative licensing model.
According to Soteria Battery CEO Brian Morin, the current collector remains an often-overlooked component in battery design, yet it significantly impacts safety and performance. He stated that improving this component can yield important gains in durability, efficiency, and overall reliability. In a statement, Morin noted that Rutgers' technology tackles the challenge from a different angle, representing a novel approach the company is eager to bring into the Battery Safety IP Exchange. By integrating complementary technologies, manufacturers gain greater flexibility in designing safer batteries.
The company added that the Battery Safety IP Exchange was created to streamline access to safety-enhancing battery technologies through a shared, collaborative licensing framework. The platform aggregates complementary intellectual property from universities, national laboratories, startups, and established industry players, aiming to lower adoption barriers and accelerate commercialization. By bringing these technologies together in a single ecosystem, the platform seeks to help accelerate the deployment of practical battery safety solutions across the lithium-ion battery industry.
