Detailed Description
The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 3, the olefin double-carbon energy storage shelter of the invention comprises a shelter body 8, and the interior of the shelter body 8 is a main body structure of the energy storage shelter.
The cabin 8 is filled with an olefin dual-carbon electrolyte. As shown in fig. 1, 2 and 4, the cabin 8 includes four poles 4 inside, and the four poles 4 are respectively located at four corners inside the cabin 8, and include two positive poles 4 and two negative poles 4, where the two positive poles 4 are located at the same side, and the two negative poles 4 are located at the same side.
The cabin body 8 is internally divided into an upper layer and a lower layer, and each layer is provided with a rectangular frame formed by alternately connecting a shell plate 3 and a bearing plate 1. The rectangular frame is formed by fixedly connecting two shell plates 3 and two carrier plates 1, wherein the carrier plates 1 are positioned below the shell plates 3. The carrier plate 1 serves to support the housing plate 3 and other structures mounted on the housing plate 3. The pole 4 sequentially penetrates through the positions where the shell plate 3 and the bearing plate 1 are connected in the two layers of rectangular frames and is connected with the bearing plate 1 and the shell plate 3. The pole 4, the shell plate 3 and the bearing plate 1 are inserted and connected to form an internal basic frame of the storage battery.
The shell plate 3 is fixedly connected with a lead connecting strip 6. In the present embodiment, the connection manner of the housing plate 3 and the lead connecting bar 6 is welding. The lead connecting strip 6 comprises a plurality of vertical thin plates which are arranged along the horizontal direction and are evenly spaced, wherein the number of the thin plates of the lead connecting strip 6 on the upper layer is less than that of the lead connecting strip 6 on the lower layer. The upper and lower lead connecting strips 6 are used to connect the positive electrode plates 7 and the negative electrode plates 5, respectively, and the number of the lead connecting strips 6 is different because the number of the positive electrode plates 7 is smaller than that of the negative electrode plates 5. In this embodiment, the thickness of the positive electrode plate 7 is about 3mm, and the thickness of the negative electrode plate 5 is less than 2mm, so that the negative electrode plate 5 is more than the positive electrode plate 7 in order to ensure uniform capacity. Therefore, in the present embodiment, the number of thin plates of the lead bonding bars 6 in the upper layer is one less than the number of lead bonding bars 6 in the lower layer.
The shell plate 3 is provided with a partition plate 2, and the partition plate 2 is connected with the thin plate of the lead connecting strip 6 in a staggered and penetrating manner and is used for separating the positive plate 7 from the negative plate 5. The separator 2 is arranged between the adjacent positive and negative polar plates 5 to prevent the positive and negative polar plates 5 from contacting and generating short circuit. The partition board 2 is divided into an upper layer and a lower layer as the shell board 3, and the two layers of partition boards 2 can be integrally processed. The partition board 2 is made of PVC material.
The positive electrode plates 7 and the negative electrode plates 5 are alternately arranged. The positive plate 7 is installed between two adjacent separators 2 and is in contact with the lead connecting bar 6 on the upper layer. The negative plate 5 is arranged between two adjacent separators 2 and is in contact with the lead connecting strip 6 at the lower layer. The positive electrode plate 7 and the negative electrode plate 5 are not directly connected to each other, but are embedded in each other through the separator 2. The positive plate 7 and the negative plate 5 are respectively connected with the upper layer lead connecting strip 6 and the lower layer lead connecting strip 6 to form the positive pole and the negative pole of the storage battery. The positive pole column 4 and the negative pole column 4 form a terminal of an electrode 9 outside the cabin 8, and are respectively connected with the positive pole and the negative pole inside the cabin 8.
When the olefin double-carbon energy storage shelter is installed and constructed, the method comprises the following steps:
s01, welding the cabin body 8 for leakage test; s02, assembling an internal basic frame; s03, inserting the negative plates 5 into the grooves and connecting the negative plates in parallel; s04, inserting the positive plate 7 into the groove and connecting in parallel; s05, inserting the separator 2 into the pole group for fixing; s06, welding the lead connecting strips 6 in series; s07, injecting an olefin dual-carbon electrolyte; s08, starting charging of the battery; s09, welding the battery in a reverse charging mode; s10, normally charging the battery in the positive direction; s11, the cabin 8 is covered for use.
According to the olefin double-carbon energy storage shelter, an olefin double-bond material is used as an electrolyte, after the olefin double-bond material is added into a battery pole group, olefin micromolecules are connected with each other through an addition reaction and multiple polymerization reactions under the action of a catalyst, a honeycomb physical space of a high polymer material is gradually formed in a lead-acid battery, active substances are filled in the honeycomb physical space, and active substance particles are relatively isolated and fixed by the honeycomb physical space. The negative plate 5 is isolated due to the honeycomb space, and the reaction condition that small molecules are combined with each other to form large-particle lead sulfate is limited, so that the negative electrode vulcanization phenomenon is reduced. The positive plate 7 is because the honeycomb space is fixed, and the honeycomb is the polymer organic matter, and is stable in acidity and hyperoxia environment, effectively ensures the physical stability of anodal active material porous nature, simultaneously because the exogenic action of honeycomb, two combinations effectively solve the positive plate 7 because the defect of porous inefficacy and argillization. Due to the basic conditions of stability, high distribution density and the like of the bonding surface of the olefin polymer honeycomb physical space and the active substance, a large number of contact surfaces form favorable channels of electrolyte sulfuric acid, the chemical polarization internal resistance of the battery is obviously reduced, and the useless work heat generated by the battery is greatly reduced. The electrolyte can increase the conductive area, reduce the current density, reduce the interface resistance, improve the conductivity of a battery pole group, improve the charge acceptance of the battery in the charging process, improve the rate of converting charging electric energy into chemical energy by 30 percent, save more than 30 percent of comprehensive electricity, reduce more than 40 percent of useless heat energy generated by consuming electric energy due to high internal resistance of the battery, and prolong the service life of the battery by more than 40 percent.
For example, after the electrolyte is diluted by adopting an olefin dual-carbon additive in a ratio of 1:7.1, the electrode plate is slotted for 30 hours, and if the current is not changed, the time is shortened to 21 hours; if the time is not changed, the current is reduced to 0.7 times.
If the dry charge battery with the same structure and without electrolyte is adopted, the common electrolyte is adopted, the 100 percent DOD cycle life is 250 times, the olefin dual-carbon additive is adopted to dilute the electrolyte at a ratio of 1:7.1, and the 100 percent DOD cycle life is 350 times.
The manufactured battery has the advantages that the battery does not generate heat, the electric quantity of heat loss is reduced, the battery is fully charged by 80% in 2 hours, and the battery can be fully charged in 4 hours; and the normal charging of the common sulfuric acid electrolyte battery requires more than 8 hours to be fully charged.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
