The Advanced Research Projects Agency - Energy (ARPA-E) has awarded $3 million from its 2015 OPEN funding to a project to develop an all-solid-state sodium battery. The proposed Na battery operates at room temperature, uses a benign and scalable solid-stack design for a long cycle life and expects to achieve a 20% improvement in energy density over state-of-the-art lithium-ion cells. Martin’s new battery will use a solid anode, cathode and electrolyte separator.
