General Motors &OneD Battery Sciences have executed a joint research development agreement focused on the potential use of OneD’s silicon nanotechnology in GM’s Ultium battery cells to drive significant increases in energy density for longer range and reduced cost. GM Ventures and Volta Energy Technologies also participated in OneD’s Series C funding round, which the company recently closed at USD 25 million.The focus of the collaboration is OneD’s SINANODE platform, which adds more silicon onto the anode battery cells by fusing silicon nanowires into EV-grade graphite. Silicon can store 10 times more energy than graphite. Increasing energy density can open the door to smaller, lighter, more efficient battery packs that could achieve higher driving range at lower cost.The collaboration on silicon anode technology is believed to be the first of its kind between two American companies. GM is rapidly scaling its Ultium EV Platform to reach 1 million units of annual EV manufacturing capacity in North America by 2025. Earlier this year, GM’s first Ultium Cells joint venture battery plant began production in Ohio, with two additional US plants under construction and a fourth also planned.At the same time, GM is building on more than a decade of advanced battery research and development with its new Wallace Battery Cell Innovation Center in Warren, Michigan, which was completed earlier this year to help significantly ramp up development and production of next-generation Ultium batteries, along with production methods that can quickly be deployed at battery cell manufacturing plants.
