Abstract

The utility model relates to a silica gel lead accumulator which comprises an accumulator tank, a positive plate, a negative plate, a baffle and an accumulator cover with a positive terminal, a negative terminal and a liquid charging pin. The utility model is characterized in that the baffle is in a tower structure with hollow out design. The utility model has the advantages that the internal resistance of the accumulator is reduced, and the charge and discharge accepting ability and the cold starting ability of the plates are fully exerted; plate area is increased, and capacity and specific energy are enhanced; service life is long, the utility model is favorable for environmental protection, charge accepting rate is high, electrolyte stratification can be prevented, electrolyte does not overflow and does not corrode workpieces, and the workpieces can work for a short time in case of breakage.

Description

The colloidal silica lead accumulator

The utility model belongs to a kind of storage battery, particularly a kind of colloidal silica lead accumulator.

At present, domestic colloid storage battery, just colloidal electrolyte is joined in the original lead acid accumulator mostly, because the electrolyte of former lead acid accumulator is dilute sulfuric acid,, also suppressed the performance of colloidal electrolyte characteristic so can not adapt to colloidal electrolyte fully, after joining lead acid accumulator for the colloidal electrolyte of different process, the capacity that has descends, and the cold-starting ability that has descends, and shortens the useful life that has etc.

The purpose of this utility model provides a kind of colloidal silica lead accumulator, and capacity is big, long service life, and performances such as cold-starting are good, and help environmental protection.

The purpose of this utility model is achieved in that it comprises the battery cap of cell jar, positive plate, negative plate, dividing plate and band positive terminal, negative terminal, fluid injection bolt, is characterized in that: dividing plate is with blank tower structure.

The utmost point gate rib of above-mentioned positive plate and negative plate is from the outside radiation shape of interpole ear.

The above-mentioned positive plate and the area of negative plate are 194 square centimeters to 230 square centimeters.

The utility model has the advantages that: adopted dividing plate, thereby reduced the internal resistance of storage battery with blank tower structure; Employing is from the utmost point gate rib of the outside radiation shape of interpole ear, and that gives full play to pole plate discharges and recharges ability to accept and cold-starting ability ,-40 ℃ of energy normal startings; Self discharge is little, and the pole plate area increases, and has improved capacity and specific energy; Long service life, acid mist is few, helps environmental protection, and the charge acceptance height can prevent electrolyte stratification, the not excessive workpiece that do not corrode, but just in case still short-term job of breakage.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is a positive and negative electrode plate structure schematic diagram.

Fig. 3 is that the blank of dividing plate is the rectangular configuration schematic diagram.

Fig. 4 is that the blank of dividing plate is the circle hole shape structural representation.

See Fig. 1-2, concrete structure is as follows: assembling positive plate 5 and negative plate 7 in each groove in the cell jar 8, dividing plate 6 is set between the positive and negative pole plate, and middle lug 9 is arranged on the wherein positive and negative pole plate, the utmost point gate rib 10 in the pole plate is from the outside radiation shape of interpole ear.Dividing plate 6 is the tower structure with blank 11.See Fig. 3, blank 11 be shaped as rectangle; See Fig. 4, blank 11 be shaped as circle hole shape; Blank shape can also be designed to other shape as required.Positive terminal 1, negative terminal 4 and fluid injection post 2 are set on the battery cap 3.
