GM and OneD Battery Sciences collaborate on joint R&D of silicon anode technology for more efficient EV batteries.
General Motors Co. (NYSE: GM) and OneD Battery Sciences announced the execution of 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 $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…
