NOVELTY - A silicon liquid storage battery consists of a shell, an upper cover, a baffle, an electrode plate, and an electrolyte. The shell and upper cover are connected with the baffle fixed in the shell. The inner shell space is divided into two or more spaces. The electrode plate and electrolyte are located in the space. The electrode plate is fixed in the space through a saddle. Each space is provided with a pair of positive and negative electrode plates. The electrolyte comprises an electrolytic solution and a repairing liquid in a volume ratio of 98.5:1.5.    USE - Silicon liquid storage battery.    ADVANTAGE - The silicon liquid storage battery has small volume, is lightweight and easy to be maintained, and has excellent charging efficiency and prolonged service life. The electrolyte has high activity at low temperature. The battery can be manufactured by an environmentally-friendly method, which is safe with respect to human.    DETAILED DESCRIPTION - A silicon liquid storage battery consists of a shell, an upper cover, a baffle, an electrode plate, and an electrolyte. The shell and upper cover are connected with the baffle fixed in the shell. The inner shell space is divided into two or more spaces. The electrode plate and electrolyte are located in the space. The electrode plate is fixed in the space through a saddle. Each space is provided with a pair of positive electrode plate and negative electrode plate. The space in the positive pole plate and negative pole plate in parallel is connected to a space of other positive electrode plate and negative electrode plate by a connecting column connected in series. An electrode plate is put into the electrolyte. The electrolyte comprises an electrolytic solution and a repairing liquid in a volume ratio of 98.5:1.5. The electrolytic solution comprises (in wt.%) silica (30-39.9), sodium silicate (12-19, preferably 17.5), sodium sulfate (12-19, preferably 15.5), sodium carbonate (10-11, preferably 10.5), amino polysiloxane (0.004-0.012, preferably 0.08), polyvinyl chloride (0.015-0.03, preferably 0.02), and water (remainder). The repair solution is prepared using (in parts weight) concentrated sulfuric acid (90-100, preferably 95), magnesium sulfate (0.4-0.6, preferably 0.5), zinc sulfate (0.9-1.1, preferably 1), tartaric acid (1.6-1.8, preferably 1.7), EDTA (0.4-0.6, preferably 0.5), aluminum sulfate (0.25-0.35, preferably 0.3), sodium carbonate (1.5-2.5, preferably 2), potassium sulfate (0.9-1.1, preferably 1), phosphoric acid (6-7, preferably 6.5), glycerol (3-4, preferably 3.5), and purified water (remainder). The electrode plate is made of plastic or carbon fiber material, and consists of a high-temperature-resistant fixing plate and an active material layer on the plate surface. The active material layer is formed by plating on the surface to a fixed thickness of 0.1-1.5 mm. The negative active material layer of the plate is lead dioxide plating layer, and the positive active material layer is electroplated layer.
