1. A composition of matter comprising:
a LMOF electrode made of Lithium Manganese Oxyfluoride (LMOF), with 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 electrode so that LMOF is between 55 percent and 85 percent by mass of a composition of the LMOF electrode and the SPE is between 7.5 percent and 20 percent by mass of the composition of the LMOF electrode,
the SPE saturates the separator so that the SPE resides both on the separator top side and the separator bottom side 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.
