Silicon Forging Ahead for Higher-Performance Battery Anodes

Silicon-infused anodes, already widely considered one of the most promising candidate technologies for the next significant performance-improvement phase of electric-vehicle (EV) Lithium-ion (Li-ion) batteries, enjoyed a significant boost in September 2022, when GM and OneD Battery Sciences revealed a joint research and development agreement to study the potential to use OneD’s silicon nanotechnology in GM’s Ultium battery cells. General Motors and Volta Energy Technologies also invested in a $25-million Series C funding for OneD, a move interpreted by some as a vote of confidence that silicon-anode technology is poised to make a comparatively imminent impact on EV battery development.
