French materials giant Saint-Gobain is working with UK/Israeli startup Addionics to develop next generation lithium ion solid state battery technology with novel electrode components.
The partnership is part of the US BIRD Energy programme that aims to boost EV battery performance.
Saint-Gobains’ initial technological breakthrough with its novel solid state battery components enables safer battery operation and low-cost manufacturing, by simplifying the production flow and eliminating intermediate processes. Saint-Gobain’s electrolytes have demonstrated high Li-ion conductivity comparable with the state-of-the-art solid electrolytes and offer additional potential performance, manufacturing and economic benefits.
Addionics smart 3D electrode technology enables enhanced electrical current collection across the volume of thick battery electrodes and improved material usage leading to a boost in battery energy density and cycle life, as already demonstrated in more conventional battery platforms. The technology also helps to solve the interfacial resistance issues commonly observed in solid state battery designs
"We believe our unique solid-state electrolyte technology will offer enhanced safety and performance for next generation batteries with the potential for low cost manufacturing. This collaborative project is consistent with Saint-Gobain’s purpose,” said Dr. Mark Hampden-Smith, VP Business and Technology Strategy, Saint-Gobain Ceramics
“Using our battery technology applications such as EV can deliver better performance,” said Dr Moshiel Biton, CEO of Addionics. “The technology enables to save cost, achieve high performance and generate less waste. We start with cars but go beyond, our technology can support the creation of a better environment and a more sustainable future”.
“We are excited to support this partnership between the Addionics and Saint-Gobain and we look forward to the technological advancements they will make. This project is of great interest to both countries seeking developing and commercializing clean energy technologies that support innovative technologies and improve economic competitiveness.” said Limor Nakar-Vincent, Deputy Executive Director of Business Development & BIRD Energy.
Addionics provides specialized improved rechargeable batteries by redesigning their architecture with smart 3D metal structures, using patent-protected, cost-effective, scalable, metal fabrication manufacturing process methods. The novel smart 3D electrodes support greater loading of active material enabling higher energy density, while minimizing the internal resistance and improving mechanical longevity, thermal stability and other fundamental limitations that affect degradation in standard batteries. The solution is also software-based—they use an AI algorithm to optimize the best structures. The technology enables achieving a significant step-change in the performance of all key battery characteristics simultaneously.
BIRD (Binational Industrial Research and Development) Foundation works to encourage and facilitate cooperation between U.S. and Israeli companies in a wide range of technology sectors and offers funding of up to half for selected projects. The funding is repaid as royalties from sales of products that were commercialized as a result of BIRD support.
- $6m funding for Israeli 3D battery material firm
- $17m for BIRD joint US-Israeli clean energy projects
