A battery cell structure, a system including the structure, and a method of fabricating the structure. The structure includes: a cell housing; a cathode in the cell housing, the cathode including a cathode material; a cathode current collector adjacent the cathode in the cell housing; an anode in the cell housing, the anode including an anode material; an anode current collector adjacent the anode in the cell housing; a separator in the cell housing between the cathode and the anode. The cathode material comprises a recycled material including a contaminant, and the battery cell structure further includes a solid-state electrolyte disposed in the cell housing to at least partially prevent the contaminant from growing.
