The utility model is realized by adopting following technical scheme:

Manufacture and design a kind of multipole ear plate-type battery, comprise cell groove, positive bus, negative bus-bar, grid, especially described storage battery comprises the cell groove more than, and the lug more than two is arranged on each grid in every cell groove.

Positive bus more than two is arranged in the described cell groove.

Negative bus-bar more than two is arranged in the described cell groove.

Described storage battery has the middle cover more than two, and described middle cover is arranged on the both sides of storage battery

Described storage battery has the anodal leading-out terminal more than two.

Compared with prior art, lug quantity and corresponding the improved battery structure of the utility model by increasing every pole plate makes storage battery of the present utility model when big electric current, high power discharge, and battery performance can improve more than 30%; Can thoroughly solve because the concentrated electrode plate grid corrosion fracture problem that causes the lug root of electric current; Simultaneously because the improvement of CURRENT DISTRIBUTION can improve the utilance of lead plaster greatly; Because the improvement of CURRENT DISTRIBUTION can improve initial charge efficient again, shorten the initial charge time, particularly adopt the green plate battery effect that is internalized into obvious especially.

Embodiment

Below in conjunction with accompanying drawing and two embodiment the utility model is further described in detail.

With reference to Fig. 3 A, Fig. 3 B～Fig. 8, manufacture and design a kind of multipole ear plate-type battery, comprise cell groove 2, positive bus 21, negative bus-bar 22, grid 10, described storage battery comprises the cell groove 2 more than two, and the lug 11 more than two is arranged on each grid 10 in every cell groove 2.

Positive bus 21 more than two is arranged in the described cell groove 2.

Negative bus-bar 22 more than two is arranged in the described cell groove 2.

Described storage battery has the middle cover 51 more than two.

Described storage battery has the anodal leading-out terminal 25 more than two.

Described storage battery has the negative pole leading-out terminal 26 more than two.

Among the embodiment one shown in Fig. 3 A, Fig. 3 B, lug 11 more than two is set at the top of grid 10, positive bus 21 and negative bus-bar 22 in every cell groove 2 all have more than two, and the anodal leading-out terminal 25 and the negative pole leading-out terminal 26 of storage battery also all have more than two.

Among the embodiment two shown in Figure 4, lug 11 more than two is set at the top of grid 10, be made into positive plate, negative plate has only a lug, positive bus 21 in every cell groove 2 has more than two, negative bus-bar 22 is one, and the anodal leading-out terminal 25 of storage battery has more than two, and negative pole leading-out terminal 26 can be one.
