GM collaborates with OneD Battery Sciences on R&D of EV battery technology

General Motors Co. and OneD Battery Sciences, Palo Alto, Calif., have 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 increases in energy density for longer range and reduced cost.

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.

GM is rapidly scaling its Ultium EV platform to reach 1 million units of annual EV manufacturing capacity in North America by 2025.
