#CMT# #/CMT# The combination has a metallic conductive electrode (1), an electrolyte and a semiconductor (3) arranged in non-transmissive manner such that different types of ions at the electrode are electrochemically reduced by electron absorption from the semiconductor during charging or oxidized by electron transfer to the semiconductor or metals are electrochemically oxidized. Voltage difference between the electrolyte and the semiconductor corresponds to voltage difference externally applied during charging such that electrochemical processes are carried out vice versa during discharging. #CMT# : #/CMT# The semiconductor is designed as n-type semiconductor and a p-type semiconductor. #CMT#USE : #/CMT# Combination of a battery e.g. reversible battery such as lithium-ion battery, and capacitor i.e. film capacitor, for reversibly storing electrical power with high energy density for a fossil fuel-powered vehicle. Can also be used for a wind-power plant. #CMT#ADVANTAGE : #/CMT# The battery and the capacitor are combinedly arranged, so that the need of separating layers for selective mass transportation can be avoided. The voltage difference between the electrolyte and the semiconductor corresponds to the voltage difference externally applied during charging such that the electrochemical processes are carried out vice versa during discharging, thus storing around 25 kilowatt-hours of electrical energy. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating reduction of different types of ions from ionic compounds by electron supply at an electrode during charging. 1 : Metallic conductive electrode 2 : Volume of ions 3 : Semiconductor 3a : Depletion region 4 : Arrester #CMT#INORGANIC CHEMISTRY : #/CMT# The n-type semiconductor consists of n-doped polycrystalline silicon, magnesium silicide, magnesium stannide, tin sulfide, antimony sulfide and bismuth sulphide. The p-type semiconductor consists of p-doped polycrystalline silicon, zinc antimonide, magnesium antimonide, magnesium bismuthide and copper sulfide. #CMT#ORGANIC CHEMISTRY : #/CMT# The electrochemically stable nonprotic organic solvent is selected from ether such as monoethylene glycol dimethyl ether, diethylene glycol dimethyl ether and polyethylene glycol ether, amide such as formamide and N-dimethylacetamide, organic carbonate such as propylene carbonate and ethylene carbonate, phosphoric ester such as tricresyl phosphate, mono ethylene glycol monomethyl triphosphate and diethylene glycol monomethyl triphosphate. |
