摘要： A cathode active material includes NaxMO2 having at least a first phase, a second phase different from the first phase, and a third phase that is different from the first and second phases, wherein each phase is independently selected from Pm or On, where m and n are individually an integer, M is a transition metal or a mixture of transition metals, and x is greater than 0 and less than or equal to 1.

摘要： An electrochemical device includes a cathode including elemental selenium, elemental sulfur, or selenium-sulfur containing composite; a negative electrode; a separator; and an electrolyte including a poly(alkyleneoxide) siloxane; and a salt; wherein a concentration of the salt in the electrolyte is sufficient to minimize dissolution of polysulfides/polyselenides formed during cycling of the device.
