More Information
Summary:A sodium ion battery. The battery includes a cathode that includes sodium, an electrolyte that include sodium, and an electrochemically active anode material. The electrochemically active anode material includes an electrochemically active phase and an electrochemically inactive phase. The electrochemically active phase and the electrochemically inactive phase share at least one common phase boundary. The electrochemically active phase does not comprise oxygen, sulfur, or a halogen. The electrochemically active phase is essentially free of crystalline grains that are greater than 40 nm.
