General Motors and OneD Battery Science announced on September 29 the execution of a joint research and development agreement, focusing on the potential application of OneD's silicon nanotechnology in General Motors Ultium battery cells to improve storage capacity. energy density to extend battery life and reduce costs.
GM Ventures and Volta Energy Technologies also participated in OneD's Series C financing, which recently closed a $25 million financing.
The collaboration focuses on OneD's SINANODE platform, which adds more silicon to battery anodes by fusing silicon nanowires into EV-grade graphite. The material can store 10 times more energy than graphite, dramatically increasing the energy density, thus leading to smaller, lighter, and more efficient battery packs.
"GM designed Ultium to be an extremely flexible platform so we can continue to improve our batteries as battery technology advances," said Kent Helfrich, GM's chief technology officer, GM R&D vice president, and GM Ventures president. Our partnership with OneD will focus on continuing efforts in electric vehicle range, performance and cost."
General Motors said it is rapidly expanding the scale of its Ultium electric vehicle platform, with an annual production capacity of 1 million electric vehicles in North America by 2025. GM's first Ultium Cells joint venture battery plant in Ohio began production earlier this year, with two other U.S. plants under construction and a fourth planned.
At the same time, GM opened the new Wallace Battery Cell Innovation Center in Warren, Michigan, building on more than a decade of advanced battery research and development. Completed earlier this year, the center aims to help with the development and production of next-generation Ultium batteries, as well as the search for a production method that can be quickly deployed to battery manufacturing plants.
