Abstract

The invention relates to a preparation method for a high-voltage arc heat elimination battery. The preparation method comprises the following steps of: 1, riveting a phosphorized fastening strip and a lower end plate to form a fastening frame; 2, putting an insulation assembly into the fastening frame; 3, classifying galvanic piles into two groups, wherein one group is put on the insulation assembly in the step 2; 4, putting a middle partition plate on the galvanic piles on the insulation assembly in the step 3, putting the other group of galvanic piles on the middle partition plate, and putting another insulation assembly; and 5, arranging an upper end plate and fastening the galvanic piles, and thus the high-voltage arc heat elimination battery is prepared. A metal end plate is phosphorized, so that the strength of the conventional metal plate is retained, and the metal surface is insulated; therefore, a phenomenon of induction voltage of the end plate during discharging is avoided, electric arc produced by electric field intensity between a monomer battery and the end plate is prevented, and the security of the battery is guaranteed; the middle partition plate is additionally arranged in the galvanic piles and connected with the fastening strip, so that the galvanic piles are separated in a vertical direction, and relatively high galvanic piles are classified into two small galvanic piles; and therefore, the moment of the monomer, which is generated under the same mechanical condition, becomes small, and the stability of the galvanic piles is improved.

Description

Eliminate the preparation method of high-voltage arc thermal cell

Technical field

The invention belongs to the thermal cell technical field, especially relate to a kind of preparation method who eliminates the high-voltage arc thermal cell.

Background technology

Present employed thermal cell pile mechanism is the fastening frame of end plate and bracket formation up and down; End plate separates through insulation assembly and cell up and down; This mechanism can guarantee that whole stack has good endurance environment capacity under the prerequisite that guarantees the insulation of output circuit and fastening frame, the thermal cell pile is being born under certain mechanical condition; Still can keep original state, and then guarantee that the entire cell performance is unaffected.Yet this kind structure down can not be suitable fully in extra-high pressure (comprising the high pile that high voltage causes).The thermal cell of extra-high pressure has arc phenomenon to occur at random in discharge process under the condition of quoting original pile mechanism, causes pile short circuit or battery to burst.In addition, because the superelevation pile that causes of extra-high pressure deformation has taken place bearing under the mechanical environment, local cell protrusion finally lost efficacy because of battery power down pressure or short circuit guiding discharge.

Summary of the invention

The objective of the invention is to overcome the weak point of prior art, provide a kind of and avoid having in the discharge process arc phenomenon to occur at random, and cause pile short circuit or battery to burst, cause the preparation method of the elimination high-voltage arc thermal cell of battery failure.

The objective of the invention is to realize through following technical scheme:

Eliminate the preparation method of high-voltage arc thermal cell, comprise following preparation process:

The bracket of widening that 1. will carry out after phosphatization is handled is formed one with bottom plate through rivet, the formation fastening frame;

2. the insulation assembly of thermal cell known technology is put into fastening frame;

3. the pile that cell is constituted is divided into two groups, and one group of pile is placed on the 2. middle insulation assembly;

4. in 3. median septum being placed on one group of pile of insulation assembly, put into another part above the median septum again after, place insulation assembly once more;

5. place upper head plate and fastening pile at last, with bracket punching and fastening, promptly process the making of eliminating the high-voltage arc thermal cell by screw at upper head plate and the corresponding screw of median septum place.

And said upper and lower end plate and bracket are corrosion resistant plate.

Advantage of the present invention and beneficial effect are:

1, used metal end plate is handled through alramenting in the pile of the present invention; The intensity that has promptly kept original metallic plate; Can make the end sheet surface insulation through phosphatization again; And then avoid end plate induced voltage in discharge process, to occur, and stopped between cell and the upper head plate electric arc that produces because of electric field strength, guaranteed the safety of battery.

2, the present invention adds median septum in pile inside, and it is connected with bracket, and pile is separated up and down, and higher pile is divided into two little piles, diminishes thereby make monomer under equal mechanical condition, produce moment, strengthens the stability of pile.

Description of drawings

Fig. 1 looks sketch map for the preparation method master that the present invention eliminates the high-voltage arc thermal cell;

Fig. 2 is the vertical view of Fig. 1.

Label among the figure is respectively: 1. bottom plate; 2. insulation assembly; 3. pile; 4. median septum; 5. bracket; 6. screw; 7. upper head plate.

Embodiment

Below in conjunction with accompanying drawing and through specific embodiment the present invention is made further detailed description, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.

With reference to accompanying drawing 1-Fig. 2:

1. will carry out stainless steel after phosphatization is handled and widen bracket 5 and form one through rivet, constitute fastening frame with stainless steel bottom plate 7;

2. the insulation assembly 2 of thermal cell known technology is put into fastening frame;

3. the pile 3 that cell is constituted is divided into two groups, and one group of pile is placed on the 2. middle insulation assembly;

4. in 3. median septum 4 being placed on one group of pile of insulation assembly, put into another part above the median septum again after, place insulation assembly once more;

5. place stainless steel upper head plate and fastening pile at last, with bracket punching and fastening, promptly process the making of eliminating the high-voltage arc thermal cell by screw at upper head plate and the corresponding screw of median septum place.

Manufacturing process of the present invention:

Operation principle of the present invention is following:

1. handle through improved insulation assembly and phosphatization and avoid end plate induced voltage in discharge process, to occur, stopped the generation condition of electric arc between cell and the upper head plate;

2. through adopting median septum and increasing the intensity that the bracket size has increased pile, avoid the deformation of superelevation pile in mechanical test that causes by extra-high pressure.

Claims

1. preparation method who eliminates the high-voltage arc thermal cell is characterized in that: comprise following preparation process:

2. the preparation method of elimination high-voltage arc thermal cell according to claim 1 is characterized in that: said upper and lower end plate and bracket are corrosion resistant plate.
