Abstract
The utility model relates to a and standard 1 # 、2 # 、5 # The lead-acid accumulator for general use includes several basic parts of plastic casing, positive and negative electrodes, electrolyte and other parts, and its structure includes positive electrode core, positive electrode active material, isolating sleeve, liquid absorbing film, isolating film, negative electrode active material, negative electrode plate, liquid absorbing film, isolating film and casing successively from the inner layer to the outer layer. The battery can be charged and discharged for many times (more than 30 times), and is low in price. Compared with the zinc-manganese battery with the same model, the zinc-manganese battery has the advantages of large short-circuit current, high discharge voltage and the like, and can replace the zinc-manganese battery widely used at present.
Description
The utility model belongs to the electrochemistry field is a cylindrical lead-acid storage battery.
Standard 1 used in general ＃ 、2 ＃ 、5 ＃ The zinc-manganese dry cell is composed of cylindrical shell (as negative electrode), central carbon rod (as positive electrode), sulfuric acid (as electrolyte) and other basic parts. The battery is used up and then is used up, and can not be charged for use for many times; the storage time is long at ordinary times, and the electrolyte is easy to overflow and corrode the device. The general lead-acid accumulator consists of several groups of electrode plates and corresponding electrolyte layers, and the shape is square, although it can be charged for several times, it can not be matched with standard 1 ＃ 、2 ＃ 、5 ＃ The battery is universal. Nickel cadmium batteries can be recharged many times, but are expensive.
The utility model aims to provide a charging and discharging device which can be charged and discharged for a plurality of times,and can be compared with Standard 1 ＃ 、2 ＃ 、5 ＃ The battery is universal, simple in structure and low in cost.
The utility model relates to a cylindrical lead-acid storage battery, the structure is shown as the attached drawing. It includes several basic parts of cylindrical plastic shell, cover plate, positive and negative electrodes and electrolyte. The structure of the composite material sequentially comprises from an inner layer to an outer layer: the battery comprises a positive electrode core 1, a positive electrode active material 2, an isolation sleeve 3, a liquid absorption film 4, a transparent isolation film 5, a negative electrode active material 6, a negative electrode plate 7 in the negative electrode active material layer, a liquid absorption film 8, a transparent isolation film 9 and a battery shell 10, wherein electrolyte 11 is absorbed in the liquid absorption films 4 and 8, a cover 12 is used for sealing the battery, 13 is a positive electrode column, and 14 is packaging paper.
The positive electrode core 1 of the battery adopts a lead bar, the negative electrode plate 7 adopts a lead plate, the positive and negative active substances adopt lead powder, the electrolyte 11 adopts sulfuric acid, the isolation sleeve 3 adopts glass fiber or polyester fabric, the liquid absorption films 4 and 8 adopt glass cotton, the transparent isolation films 5 and 9 adopt polyester materials, and the battery shell 10 adopts modified polystyrene plastic.
In order to facilitate the discharge of the reaction gas in the battery, the cover plate 12 near the positive electrode core is provided with a vent hole 15. The vent hole is provided with a bulge 16 at one end of the inner side of the battery cover plate, the height of the bulge is 0.4-1 cm, and the effect of the vent hole is that liquid is prevented from flowing out of the vent hole when the battery is inverted.
The battery is characterized by multiple charging and discharging, generally more than 30 charging and discharging times, and low price which is only 3 times of that of the zinc-manganese battery with the same model. In addition, compared with zinc-manganese batteries, the short-circuit current of the zinc-manganese battery is 3-5A, and the discharge voltage of the zinc-manganese battery is 1.5V-0.75V, which is taken as an example of a No. 1 battery. The short-circuit current of the battery is 10-15A, and the discharge voltage is 2V-1.7V. The battery can replace the zinc-manganese battery widely used at present.
The utility model discloses press 1 ＃ 、2 ＃ 、5 ＃ The standard size of the battery designs the internal dimensions of each part of the battery.
Example (b): a No. 1 battery is manufactured, the external dimension is phi 33 multiplied by 63mm, the positive electrode core phi is 3mm, the thickness of the positive electrode active material layer is 5mm, the wall thickness of the isolation sleeve is 0.1mm, the thicknesses of the liquid absorption films 4 and 8 are respectively 2mm, the thickness of the negative electrode active material layer is 3mm, the thickness of the negative electrode plate is 0.2mm, and sulfuric acid is used as electrolyte. The manufacturing process is the same as that of a common lead-acid battery. The cover is sealed with epoxy resin.
The attached drawing is an axial and radial half-section of the battery
