Abstract:
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.
