Abstract
The utility model discloses a kind of lead accumulator grid, pole plate and lead accumulators.A kind of lead accumulator grid, including frame rib and crisscross lateral rib and vertical rib in frame rib, the transverse direction rib and vertical rib are bent waviness, and the ripple between consecutive web shifts to install.The utility model lead accumulator grid by lateral rib and vertical rib by being bent waviness, and the ripple between consecutive web shifts to install, so that the active material adhesive force of pole plate is stronger, it is not easy to fall off, so as to which the thickness of grid and pole plate is suitably reduced, under equal volume, thin plate multi-disc, the response area that can get bigger, to improve the high power discharge performance of battery.
Description
Technical field
The utility model is related to lead accumulator production technical field, more particularly to a kind of lead accumulator grid, pole plate and
Lead accumulator.
Background technology
Lead-acid accumulator is long because having outstanding cheap, reliable in quality, heavy-current discharge, easy maintenance, service life
The features such as be applied to all trades and professions, Constructing data center scale increasingly increases in recent years, increasingly along with server power
Greatly, the battery capacity mating with it drastically rises, and charging time requirement is shorter and shorter, this is proposed to the performance of lead-acid accumulator
More challenges, high-power battery are mainly used for the standby emergency power supply of data center's uninterruptible power system, but number big absolutely
Data center, commercial power supply ensures that well accumulator deep discharge probability is relatively low, but discharges the high current invariable power of short time
It is required that high, this proposes certain requirement to the invariable power cycle life of high-power battery, is determined for compliance under actual application environment
Invariable power cycle life become formulate high-power battery professional standard a vital task.
High power lead-acid accumulator is " big data " product of the time, under the premise of ensureing certain cycle life, is had
The invariable power discharge capability of the promotion battery cell of effect is reduced investment outlay, it is believed that the gradual perfection of lead-acid accumulator will become number
A nova in being built according to center.
It is electrochemical reaction when battery discharge, the transfer of electronics generates electric current, realizes that battery discharge, electrochemical reaction need
Sulfate ion, the transfer velocity of electronics be far longer than sulfate ion electrolyte diffusion velocity, at positive and negative pole surface
When sulfate ion lacks, positive and negative electrode potential deviates respectively, and cell voltage is caused to decline, and both common battery was put
Voltage declines when electric, and battery discharge current is bigger, when being both in high power discharge, the sulfate ion of battery plus-negative plate plate surface
Shortage is more serious, and the voltage decline of battery is bigger.
Utility model content
The utility model provides a kind of lead accumulator grid, active material when pole plate is made in view of the deficiencies of the prior art
Strong adhesive force, so as to reduce slab lattice thickness, corresponding electrode thickness also reduces, to accomplish under equal volume
Thin plate multi-disc obtains the response area of bigger.
A kind of lead accumulator grid, including frame rib and crisscross lateral rib in frame rib and vertical
Rib, the transverse direction rib and vertical rib are bent waviness, and the ripple between consecutive web shifts to install.
Preferably, the lead accumulator grid is to rush web plate grid.It is good compared with the grid intensity of casting to rush web plate grid, it is not easily broken
It splits, and corrosion resistance improves, thus in the case where ensureing grid intensity, the more refinement that grid rib can be done, grid
Thickness smaller.
The utility model additionally provides pole plate prepared by the lead accumulator grid.The plate active material adhesive force
By force, it prevents from falling off.Under equal volume, pole plate can be done thinner, thin plate multi-disc shape may be used when preparing lead accumulator
Formula, to obtain the response area of bigger.
The utility model additionally provides lead accumulator prepared by the pole plate.
Preferably, the thickness of the lead accumulator, positive and negative pole plate is identical, and how a piece of positive plate is compared with negative plate.Just,
The thickness of negative plate is identical, to manufacturing grid and during pole plate, same mold or equipment can be used, without into
Row adjustment, only the alloying component of grid and active material ingredients are adjusted according to the needs of positive and negative pole plate.Positive plate
It is how a piece of compared with negative plate be it is relatively thin in electrode thickness, and positive and negative pole plate thickness it is identical under the premise of, total thickness keep not
Become, while under conditions of ensureing positive active material abundance, increases inside battery response area.
Preferably, the lead accumulator, including multiple poles group, the positive and negative lug between consecutive roots group is by same confluence
Row is connected directly.Using the direct-connected form for exempting from lead gap bridge, it is possible to reduce internal resistance is lost in discharge process.
The utility model lead accumulator grid by lateral rib and vertical rib by being bent waviness, and consecutive web
Between ripple shift to install so that the active material adhesive force of pole plate is stronger, it is not easy to fall off, so as to by grid
It is suitably reduced with the thickness of pole plate, under equal volume, thin plate multi-disc can get the response area of bigger, to improve battery
High power discharge performance.

Specific implementation mode
As shown in Figures 1 to 3, a kind of lead accumulator grid 1, including frame rib 11 and handed in length and breadth in frame rib 11
Wrong lateral rib 12 and vertical rib 13, lateral rib 12 and vertical rib 13 are bent waviness, and between consecutive web
Ripple shift to install.Lateral rib 12 and vertical rib 13 are bent waviness, and the ripple dislocation between consecutive web
Setting, so that the active material adhesive force of pole plate is stronger, it is not easy to fall off, so as to by the thickness of grid 1 and pole plate
Appropriate to reduce, under equal volume, thin plate multi-disc can get the response area of bigger, to improve the high power discharge of battery
Performance.1 Shanghai of grid is equipped with lug 14.
Lead accumulator grid 1 is to rush web plate grid.It is good, not easy to break and anticorrosive compared with the grid intensity of casting to rush web plate grid
Performance improves, thus in the case where ensureing grid intensity, the more refinement that grid rib can be done, slab lattice thickness smaller.
As shown in Figures 4 and 5, grid 1 is prepared into pole plate, positive plate 2 is identical with the thickness of negative plate 3, to manufacture
