Classification: CPC C  H  Y | IPC C  H

Claim 8:
9. A composition matter of an energy storage device comprising:
a cathode made of Lithium Manganese Oxyfluoride (LMOF), yielding the approximate stoichiometry of Li2MnO2F, the cathode having a surface;
a single layer separator adhering to the surface, the separator being a dielectric that is conductive for Lithium ions but not electrons, the separator having a separator top side and a separator bottom side; and
a solid polymer electrolyte (SPE),
wherein:
the SPE saturates the LMOF so that the LMOF is between 55 percent and 85 percent by mass of the cathode and the SPE is between 7.5 percent and 20 percent by mass of the cathode,
the SPE saturates the separator so that the SPE resides both on the separator top side and the separator bottom side and so that the SPE residing on the separator top side contacts the surface, and
the LMOF exhibits X-Ray Diffraction spectrum peaks between twenty-two and twenty-four 2-theta degrees, between forty-eight and fifty 2-theta degrees, between fifty-four and fifty-six 2-theta degrees, and between fifty-six and fifty-eight 2-theta degrees.
