General Motors and OneD Battery Sciences are teaming up on a joint research venture into building more efficient batteries for electric vehicles.

The partnership will focus on using OneD’s silicon nanotechnology in GM’s Ultium battery cells to extend range, improve performance and cut costs. The automaker said Thursday that OneD’s Sinanode platform, which uses silicon instead of graphite for a tenfold increase in energy, can pave the way for smaller, lighter and more efficient battery packs.
