General Motors (GM) and OneD Battery Sciences, a California-based battery development company, have entered a joint research and development agreement to increase energy density and reduce production costs in future GM EV batteries. The joint R&D will focus on the potential use of OneD’s “SINANODE” silicon nanotechnology in GM’s Ultium battery cells. The advanced technology adds more silicon onto the anode battery cells by fusing silicon nanowires directly to the graphite anode, resulting in significant increases in energy density. The battery development company already has over 240 granted patents on its technology, and plans to licence SINANODE products to industrial partners to scale manufacturing faster and at lower cost.

GM plans to increase production capacity of its Ultium EV platform in North America to one million units per year by 2025, and has begun production at its first Ultium cell plant earlier this year with two further facilities under construction and a fourth site in the planning stages. GM Ventures also participated in OneD’s Series C funding round, which closed at USD25 million…
