Abstract
A hybrid polymer capacitor includes an anode layer, a cathode layer, a plurality of layers stacked between the anode layer and the cathode layer, and a liquid electrolyte. The plurality of layers includes: (i) a not hydrated metal oxide layer having a thickness of at least 100 nm in a stacking direction, and (ii) a hydrated metal oxide layer arranged on a surface of the not hydrated metal oxide layer. The liquid electrolyte has a conductivity of at least 200 μS/cm at 30° C. and a water content of at least 0.5%. The hydrated metal oxide layer and the not hydrated metal oxide layer are impregnated with the liquid electrolyte.
