Detailed description of the invention
The embodiment of the positive grid of novel high-performance tubular cells of the present invention is illustrated below in conjunction with Fig. 1 to Fig. 3.
The present invention is a kind of positive grid of novel high-performance tubular cells, as shown in Figure 1 to Figure 3, by lug 1,
Collector 2, comb seat 3, grid skeleton 4, flank 5, totally 5 part composition.Middle side part on collector 2
Vertically it is provided with lug 1, on the downside of described collector 2, is provided with several rows of base 3, institute along collector 2 length direction
Stating comb seat 3 connection and have the column grid skeleton 4 vertical with collector 2 length direction, grid skeleton 4 is along perpendicular
To being provided with several the most prominent flanks 5, the described flank 5 distribution density on grid skeleton 4 is the end of by
Portion gradually becomes thin to top.
As shown in Figure 4 and Figure 5, described flank 5 is vertical in being interspersed up and down along grid skeleton 4.At this
In embodiment, a pair, upside flank 5 and a pair, downside flank 5 are distributed in decussation.
Additionally, described flank 5 is in the widest two flat-sided flat structures.The thickness of described flank 5 is by plate
Grid skeleton 4 Inside To Outside is the most thinning.The height of described flank 5 by grid skeleton 4 Inside To Outside by
Step step-down.
When the positive grid of tubular cells uses powder filling or fills the production of grain technique, flank external diameter ≈ comb seat internal diameter-
(0.1～0.5mm).The positive grid of tubular cells uses when squeezing cream or grouting process production, and flank external diameter ≈ squeezes cream pipe
External diameter-(0.1～0.5mm).
The cross-sectional area of described grid skeleton 4 is gradually increased to top by bottom.Make plate active material anti-
The electric current that should generate effectively is collected conduction by the bottom of grid skeleton 4 to top.
Described collector 2 is linearly gradually increased to the sectional area in lug direction from length direction both sides, thickness side
Linearly it is gradually reduced to lug direction to from bottom.The electric current making plate active material reaction generate passes through side
The wing 5, grid skeleton 4 and comb seat 3 more effectively collect conduction to lug 1 direction, both ensure that electric current
Effectively transmission, alleviates grid weight simultaneously, reduces material cost.
The effect arranging flank 5 in the present invention is mainly reflected in:
1. according to the diametric requirements of flank 5, grid skeleton 4 is made to essentially coincide with the center of circle centrage of comb seat,
Tubular plate active substance is made to be uniformly distributed along between grid skeleton 4 and comb, and beneficially at the bottom of tubular plate
The encapsulation in portion.
2. flank 5 is in flat structure, improves bond strength and increasing between grid skeleton 4 and active substance
Add tubular plate and become the area of stream reaction.
3. flank 5 on grid skeleton 4 under close on the structural arrangement dredged, increase activity bottom tubular plate
The response area of material, makes the reaction of each position active substance on grid skeleton 4 more uniform, improves tubular type
Plate active material utilization rate.
4. flank 5 on grid skeleton 4 vertical interlaced distribution, and under close on take thin structural arrangement, make
Tubular plate active substance is gradually increased to bottom by top with the adhesion of grid skeleton 4, effectively prevent
Tubular plate active substance settlement issues during service life, prevents due to active substance sedimentation
The pole plate blank pipe phenomenon caused, improves the service life cycle of tubular cells.
5. due to the arrangement architecture of flank 5 with grid skeleton 4, the CURRENT DISTRIBUTION on grid skeleton 4 is optimized,
Significantly more efficient being pooled on grid skeleton 4 of electric current making plate active material reaction produce is conducted, from
And improve the big electric current of tubular cells, high-rate discharge ability.
To sum up, by the enforcement of the present invention, tubular cells grid weight and the premise of dimensions are not being changed
Under, reach the purpose of tubular cells positive grid optimization design, it is ensured that the response area of plate active material and
Reaction uniformity, improve grid skeleton 4 electric conductivity, ensure that tubular cells service life during
Big electric current, the requirement of high-multiplying power discharge, to enhance grid skeleton 4 and flank 5 strong with the combination of active substance
Spend thus avoid the occurrence of tubular plate blank pipe phenomenon, improve the service life of battery.
