This invention discloses a large-area photo-chargeable aqueous zinc-ion battery, its preparation method, and its application. The method includes the following steps: Two pieces of glass with a transparent conductive layer coated on one side are taken. A positive electrode material is placed on the coated layer of one of the glass pieces. A glass fiber separator and a negative electrode material are sequentially covered on top of the positive electrode material. The other glass piece is then placed on top of the negative electrode material with its coated layer facing down. The positions of the two glass pieces are adjusted so that they are stacked alternately. Pressure is applied to the resulting stacked structure, and three sides are sealed with hot melt adhesive. After the hot melt adhesive has cured, electrolyte is injected into the unsealed side, and then this side is sealed again. The negative electrode of a diode is connected to the glass on the positive electrode side of the battery, and the positive electrode of the diode is connected to the glass on the negative electrode side of the battery, thus obtaining a large-area photo-chargeable aqueous zinc-ion battery. The battery of this invention has the advantages of high light utilization, stable charging, and low loss.
