Abstract
A long-life high-performance valve-controlled sealed lead-acid accumulator is composed of positive and negative plates, casing, electrolyte, superfine glass fibre partition and safety valve. The positive plate is the great pasted formula polar plate of also can be for thickness for rectangle (or oval) tubular polar plate, and the negative plate is the less pasted formula polar plate of thickness, and negative plate quantity is the twice of positive plate in the battery utmost point crowd. There are two negative plates between the adjacent positive plate, also have fine glass fiber baffle between two negative plates. The utility model has the advantages of small internal resistance, strong charging acceptance, large discharging current, long cycle life, no need of maintenance and the like. The device can be widely applied to the fields of various electric vehicles, solar energy, wind energy power stations, electric forklifts, post and telecommunications communication and the like.
Description
Technical field
The utility model relates to a kind of cathode absorption type valve-control sealed lead acid battery, is subordinate to the sealed lead acid storage battery field.
Background technology
Cathode absorption type valve-control sealed lead acid battery in the past, positive plate, negative plate, when ultra-fine glass dividing plate etc. is combined into battery electrode group, negative plate only manys a slice than positive plate in the utmost point group, positive plate and negative plate are staggered during combination, negative plate places positive plate then outward, be equipped with the ultra-fine glass dividing plate of one deck between the positive/negative plate, during discharge ultra-fine glass dividing plate with sulfuric acid (electrolyte) flow to electrode so that chemical reaction to take place output current, the oxygen that anode during charging (positive plate) produces can constantly see through ultra-fine glass dividing plate and carry out the transition to negative electrode (negative plate) surface, again be reduced into water by plumbous absorption of biscuit, battery avoid charging dehydration and acid mist overflowed, cause pollution environment for use.Yet, because the specification requirement of cathode absorption type valve-regulated lead-acid battery itself and the restriction of existing manufacturing technology level, the specific energy of battery only is confined to a certain scope, and this just requires utmost point group should keep certain electrode thickness and overall dimensions, guarantees enough active materials and electrolyte.During discharge, make battery can emit enough electric weight at the appointed time.Need to penetrate the distance of dividing plate longer and the oxygen that when charging anode (positive plate) produces is owing to carry out the transition to negative pole, and part oxygen sees through dividing plate and arrives negative terminal surface and absorbed and be reduced into water again by biscuit is plumbous, directly enters air chamber on the contrary and is discharged from.The oxygen combined efficiency is low, and dehydration is fast, and the useful life of battery is shorter.Owing to distance between the positive/negative plate is bigger, internal resistance is bigger in addition, and battery electrical property is also bad.Existing way is to reduce the monolithic capacity (rectangle or ellipse tube type positive plate also become the grid type plate of thinner thickness) of pole plate, increases quantity of polar plate, reduce die opening, but the production quantitative change is big, and production efficiency reduces.Particularly positive plate is because the grid attenuation, and grid intensity diminishes, and the gripping area of active material is reduced, and active material easily comes off, and it is not enough or cause internal short-circuit easily to form battery capacity, causes the useful life of battery shorter.
Summary of the invention
The purpose of this utility model provides a kind of long-life, high-performance valve-control sealed lead acid battery.
The technical solution of the utility model is: long-life, high-performance valve-control sealed lead acid battery are made up of positive plate, negative plate, ultra-fine glass dividing plate, shell, electrolyte and safety valve etc., and negative plate quantity is the twice of positive plate in the utmost point group who is made of positive and negative pole plate and dividing plate.Positive plate is that rectangle (or oval) tubular plate also can be the bigger grid type plate of thickness, and negative plate is the grid type plate of thinner thickness.
Be provided with two negative plates between every adjacent two positive plates in the above-mentioned utmost point group, utmost point group outermost layer also is a negative plate.Ultra-fine glass dividing plate is also arranged between two negative plates, promptly all be equipped with ultra-fine glass dividing plate between all pole plates.
Adopt above technical scheme, make between adjacent two positive plates of common valve-control sealed lead acid battery and only contain a slice negative plate, the grouping plan of two-layer dividing plate, become between adjacent two positive plates and contain two negative plates, the grouping plan of three layer of dividing plate, guaranteeing positive plate thickness, under the overall dimensions situation of negative plate gross thickness and battery electrode group (die opening of positive plate does not become), just make, distance between the negative plate reduces greatly, shortened oxygen and carried out the transition to the distance that negative plate need penetrate dividing plate from positive plate, improved the oxygen combined efficiency, reduced dehydration, greatly reduced the internal resistance of battery, and positive plate is owing to be tubular plate (or the bigger grid type plate of thickness), the active material difficult drop-off, have to recycle performance preferably,, prolonged battery useful life so improved the overall performance electrical performance of battery.
Description of drawings
Accompanying drawing is the utility model structural representation, and section is showed the situation of arranging of battery electrode group.
Embodiment
As figure, the utility model is by housing, electrolyte, safety valve and utmost point group constitute, negative plate quantity is the twice of positive plate in the utmost point group, two negative plates 4 and 6 are arranged between the adjacent positive plate 3,7, utmost point group's outermost layer is a negative plate 1, has between the positive and negative pole plate between 2, two negative plates of ultra-fine glass dividing plate ultra-fine glass dividing plate 5 is also arranged.
Claims (3)
1, a kind of long-life, high-performance valve-control sealed lead acid battery of being made up of positive plate, negative plate, ultra-fine glass dividing plate, battery container, electrolyte and safety valve etc., the negative plate quantity in the utmost point group who it is characterized in that being made of positive and negative pole plate and dividing plate is the twice of positive plate quantity.
2, long-life according to claim 1, high-performance valve-control sealed lead acid battery is characterized in that being provided with two negative plates between every adjacent two positive plates in the utmost point group, and utmost point group outermost layer also is a negative plate.
3, long-life according to claim 2, high-performance valve-control sealed lead acid battery is characterized in that ultra-fine glass dividing plate is also arranged between two negative plates.
