Background
The lead-acid battery has the advantages of high safety, cyclic utilization and the like. The plates of lead acid batteries are generally classified into tube-type plates and plate-type plates. The plate-type polar plate is widely applied to lead-acid batteries because of the thin thickness and the lower resistivity. The main disadvantage of the plate-type polar plate is that the lead consumption of the plate grid is more.
Lead and lead alloy are the main materials of the pole plate in the common lead-acid battery. Lead belongs to heavy metal elements and has a density as high as 11.34g/cm3. The invention patent application with the application number of CN201210107216.9 discloses a technical scheme of using a copper mesh as a main material of a lead-acid battery grid current collector, and in order to avoid corrosion of copper by sulfuric acid electrolyte in a lead-acid battery, a layer of lead still needs to be coated on the surface of the copper mesh grid to be used as the grid for the lead-acid battery.
Lead has two main uses in lead-acid batteries, one is lead material which is formed by lead through a series of processes and finally through electrochemical reaction of positive and negative active substances, the main component of the positive active substance is lead dioxide, and the main component of the negative active substance is spongy lead; another class of lead and lead alloys are materials used as current collectors for grids, busbars, terminals, and the like. The main function of the lead is to collect charge and discharge charges of active materials, and the lead is used as a conductor to input or output the charges from the battery, so as to assist the lead-acid battery active materials to complete the charging and discharging processes, and the amount of the lead and the lead alloy does not substantially change the energy output capacity of the battery. Therefore, the specific energy of lead-acid batteries is generally increased by replacing metallic lead with a low-density material or changing the formula of lead paste to increase the utilization rate of active materials.
The invention patent application of application number CN201510208608.8 discloses a method for improving the specific energy of a lead-acid battery by using a composite current collector as a base material to replace a traditional lead plate grid, and in order to avoid the corrosion of the current collector in an acid environment, a conductive adhesive transition layer and a conductive anticorrosive layer are required to be coated on the surface of the base material; the invention patent application with application number CN201610017413.X discloses a lead-acid storage battery with high specific energy and easy formation, and apparent density of positive lead paste is 4.0-4.15g/cm3The density of the negative pole lead paste is reduced to 4.1-4.15g/cm3, the apparent density of the positive pole lead paste and the negative pole lead paste is 5-15% lower than that of the positive pole lead paste and the negative pole lead paste of the common lead-acid battery, and the porosity of the lead paste with low apparent density is higher, so that the utilization rate of active substances of the positive pole and the negative pole is improved, and the specific energy of the battery is improved.
The invention patent application of application number CN201510630972.3 discloses a manufacturing method of a lead-acid battery with high specific energy, which improves the utilization rate of active substances by reducing the quality of a grid, improving the oxidation degree of lead powder, adding conductive carbon fibers and graphene into lead paste and the like. The specific energy of the lead-acid battery is improved by reducing the mass of the inactive substances.
The invention patent application with application number CN201510940669.3 discloses a structure in which a horizontal first rib and a vertical first rib are vertical, and the vertical first rib is extended into a tab; the invention patent application of application number CN200680017715.1 discloses a grid structure in which a vertical first rib and a horizontal first rib of a battery are not perpendicular, and the vertical first rib is deviated to a tab position; the invention patent application of application number CN201310289855.6 discloses a grid with an expanded mesh structure, wherein the grid with the expanded mesh structure does not distinguish a transverse first rib and a vertical first rib, the first ribs which are crossed in a longitudinal and transverse mode respectively form certain angles with the current direction in a tab, and the grid with the expanded mesh structure does not have a vertical frame.
Existing grids typically include first criss-cross ribs, e.g., a horizontal first rib and a vertical first rib, formed from the same metal material.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
According to one embodiment of the present disclosure, a grid for a lead acid battery is provided. As shown in fig. 1-4, the grid includes: a grid-like current collector and a frame. For example, the overall thickness of the grid is 0.5mm to 12 mm. Wherein the thickness is a dimension perpendicular to the major surface of the grid.
The grid-shaped current collector is used for collecting current. The grid-shaped current collector includes second ribs 103a, a plurality of first ribs 101 extending in a predetermined direction, and tabs 102. For example, the extending direction of the plurality of first ribs 101 is parallel to the predetermined direction or substantially parallel to the predetermined direction. The cross-section of the first ribs 101 is circular, semicircular, elliptical, trapezoidal, triangular, rectangular, etc. For example, a plurality of the first ribs 101 extend at the same end and are connected together to form the collective portion 103. The tab 102 is formed at the end of the collecting part 103, and the second ribs 103a are formed at the parts of the collecting part 103 other than the tab.
The same ends of the first ribs 101 are respectively connected with different parts of the second ribs 103 a. For example, the second ribs 103a are parallel to the horizontal direction and the first ribs 101 are parallel to the vertical direction. For example, the entirety of the grid-like current collector has a rectangular shape. The different parts are connected, that is, the first ribs 101 are arranged in sequence along the extending direction of the second ribs 103a, and the intervals between the first ribs 101 are the same.
The tab 102 is connected to the second ribs 103 a. For example, as shown in fig. 1 to 5, the tab 102 is connected to the second ribs 103a, and is connected to the tab 102 through the second ribs 103 a. For example, the tab 102 has a thickness of 0.2mm to 8 mm. The thickness range ensures that the tab has sufficient structural strength and conductivity.
The end, opposite to the tab 102, of the first rib 101 is provided with a cap head 104b protruding out of the first rib, and the sectional area of the cap head 104b is preferably 1.5-5 times that of the first rib 101.
Optionally, the grid-shaped current collector is made of lead or a lead alloy; or, copper wires or aluminum wires are coated in the lead. The material has good conductivity and sulfuric acid corrosion resistance.
The frame includes a plurality of support bars 201 connected together. For example, as shown in fig. 1 and 5, the frame further includes a border frame that surrounds together. The rims include a top rim 202 at an upper portion, a bottom rim 204 at a lower portion, and two side rims 203 between the top rim 202 and the bottom rim 204. The frame is rectangular as a whole. Two ends of the supporting bar 201 are respectively connected with the two side frames 203. The support bar 201 is parallel to the top rim 202 and the bottom rim 204.
As shown in fig. 1 and 5, the first ribs 101 intersect with the supporting bars 201. At least part of the first rib 101 is embedded in the supporting strip 201. The grid-shaped current collector is connected with the frame, the cap head 104b is embedded into the bottom frame 204 of the frame and cooperates with the second ribs 103 to ensure that each first rib 101 is in a straightened state in the frame, so that a grid structure is formed in the middle of the grid. The density of the frame is less than the density of the grid-shaped current collector.
In one example, a bottom rib 104a connecting two adjacent first ribs 101 is provided at an end of the plurality of first ribs 101 opposite to the tab 102. The embedding of the bottom rib 104a in the frame comprises a bottom border 204 connected to the two side borders 203.
For example, the cap head 104b is perpendicular to the first rib 101. The cap head 104b forms a T-shaped structure with the first ribs 101. For example, the cross-sectional area of the cap head 104b is 1.5 to 5 times the cross-sectional area of the first ribs 101, the cross-section of the cap head 104b is a regular structure such as a circle, an ellipse or a diamond, and the height of the cap head 104b is 1.5 to 6 mm.
In one example, as shown in fig. 1, 3 and 5, the tab 102 protrudes outward from the frame in the direction of extension of the first ribs 101. The parts of the current collector other than the tabs 102 are located in the area surrounded by the frame. For example, the portion is located inside the top rim 202, and only the tab 102 protrudes from the top rim 202. This arrangement reduces the risk of a short circuit between the second ribs 103a of adjacent plates.
It is also possible that a plurality of said first ribs 101 are of equal length, as shown in fig. 6. For example, the first ribs 101 are parallel to the sides of the rectangle. The collecting part 103 protrudes outward from the frame in the direction of extension of the first rib 101. For example, the collecting portion 103 protrudes from the top frame 202. In this example, the first ribs 101 have the same length, and the reaction areas of the plurality of electrode plates formed after the electrode active material is applied are the same.
In one example, the frame has a density less than or equal to 5g/cm3. This density is much less than that of lead and lead alloys, effectively degrading the quality of the grid. For example, the frame may be made of plastic, rubber, resin, fiber, ceramic, or glass. The material has the characteristics of low density and acid corrosion resistance. For example, the frame is formed by injection molding of an engineering plastic ABS.
For example, the frame has a thickness of 0.5mm to 12 mm. This thickness range makes the frame structurally strong.
In this example, the first ribs 101 of the grid have the function of collecting current. The supporting bars 201 are crossed and connected with the first ribs 101 to form a lattice structure. The support bar 201 serves as a structural support. The lattice structure is used to attach an electrode active material. For example, the electrode active material is a lead paste. In the manufacturing process, lead paste is coated or pressed on the grid structure. The tab 102 is located at the same end of the plurality of first ribs 101 in the extending direction.
In addition, as the same ends of the first ribs 101 are respectively connected with different parts of the second ribs 103a, the current distribution at each part of the grid is uniform, and the local over-high temperature of the grid caused by the over-high local current can be effectively prevented.
The inventor of the utility model finds that the existing grids are all made of the same metal material, such as lead, lead alloy and the like, and are in a grid structure formed by criss-cross arrangement. However, since the tab 102 is located at one end of the grid, for example, one end of the longitudinal ribs, the longitudinal direction is vertical. In operation, the current in the longitudinal and transverse ribs is not uniform. The current density of the longitudinal ribs is much higher than that of the transverse ribs, wherein the transverse direction is the horizontal direction. While the transverse ribs mainly serve as structural support. The embodiment of the utility model provides an in, change the material that density is little (for example support bar 201) with horizontal rib, still can guarantee good mass flow effect to the grid on the one hand, on the other hand can reduce the whole quality of grid effectively, improves lead acid battery's mass ratio energy.
In one example, the thickness of the first ribs 101 is 20% to 80% of the thickness of the support bar 201. Within this range, the structural strength of the stay 201 is high, and the structural strength of the formed grid is high.
In one example, the thickness of the first ribs 101 is 25% to 100% of the thickness of the second ribs 103 a. In this example, the first ribs 101 serve as structural support, requiring greater structural strength. The sectional area of the second ribs 103a gradually increases towards the tab, and the thickness is larger than that of the first ribs 101, so that the current density of the grid-shaped current collector can be ensured not to be reduced.
In one example, as shown in fig. 7, the first ribs 101 are equal in length. For example, the first ribs 101 are parallel to the side of the rectangular frame, each first rib 101 is relatively independent, each first rib 101 only serves active materials around the first rib 101, the part of each first rib 101 extending out of the frame is a tab 102, each grid has a plurality of tabs 102, after the battery is assembled, the tabs 102 are connected with the tabs of the other polarity connected in series in a one-to-one correspondence manner, so that current transmission is realized, and all tabs on the same single multi-plate can be converged on an end pole together to realize the purpose of convergence, the first rib 101 is provided with a bottom rib 104a at one end opposite to the tabs, and the bottom rib 104a is embedded into the frame bottom frame 204 to fix the relative position between the first rib 101 and the frame.
In one example, as shown in fig. 8-9, a grid is divided into two regions. In this example, the plurality of first ribs 101 is divided into a first portion S1 and a second portion S2 in the extending direction and a conduction part between the first portion S1 and the second portion S2. The extending direction is the direction in which the first ribs 101 extend axially.
A first electrode active material is attached to the first portion S1, and a second electrode active material is attached to the second portion S2. That is, by disposing different electrode active materials at different portions, different regions form different electrodes. For example, the first electrode active material is a positive electrode active material 301; the second electrode active material is a negative electrode active material 302. The conductive part is not adhered with the electrode active material.
The conduction part forms the tab 102, and the first portion S1 and the second portion S2 share the tab 102. The electrode of the first portion S1 and the electrode of the second portion S2 are connected through a common tab 102. The integral structure is equivalent to two tabs 102 of the grid shown in fig. 7 being connected together to form a common tab.
Fig. 9 discloses a bipolar plate structure formed after the grid shown in fig. 8 is coated with a positive active material 301 and a negative active material 302.
When assembled into a lead acid battery, the first portion S1 and the second portion S2 each serve as electrodes for different battery cells. For example, the second portion S2 and the negative electrode active material 302 serve as a negative electrode of one cell, and the first portion S1 and the positive electrode active material 301 serve as a positive electrode of another cell adjacent to the above cell. With this arrangement, two battery cells are connected in series. Due to the common electrode lug 102, a conduction element is not required to be additionally arranged between the two battery units for conducting.
In addition, the common tab 102 is arranged in a manner that the connection between different battery units is firmer, and the overall strength of the lead-acid battery is higher.
