Abstract
A cathode for use in an electrochemical device, the cathode including a polymer including a backbone, including a polyalkyleneimine-cobalt complex (PEI-Co complex), wherein polyalkyleneimine is coordinated to cobalt; and an electrode material effective for an oxidation-reduction reaction of oxygen, wherein oxygen is a cathode active material.
Claims16
A cathode for use in an electrochemical device, the cathode comprising:
- a polymer comprising a backbone comprising a polyalkyleneimine-cobalt complex, in which a polyalkyleneimine is coordinated to a cobalt metal;
- and
- an electrode material effective for an oxidation-reduction reaction of oxygen wherein oxygen is a cathode active material.
An electrochemical device for an oxidation-reduction reaction of oxygen, the electrochemical device comprising:
- a member that reversibly adsorbs and desorbs oxygen,
- wherein the member comprises a polymer comprising a backbone comprising a polyalkyleneimine-cobalt complex in which polyalkyleneimine is coordinated to a cobalt metal.
