Abstract
The utility model provides a rectangular lithium/thionyl chloride battery, wherein the battery electrode is designed into a slice with winding structure. The utility model is able to adjust the internal structure, so that the lithium battery has the advantages of larger load performance in particular to the output capacity under minus 40 degrees centigrade.
Description
Technical field
The utility model relates to a kind of square lithium/thinly chloride battery.
Background technology
Existing square lithium/thinly chloride battery, be to be that negative pole, thionyl chloride are positive active material and electrolyte with the lithium metal, with carbon is the lithium battery of reaction carriers, as shown in Figure 1, constitute shell mechanism by housing 1 and top cover lid group 2, wherein top cover lid group 2 comprises glass insulator 3, sealing nail 4 and anode collection post 5.At inside battery, constituted by negative pole lithium sheet 6, anodal carbon bag 7 and the barrier film 8 that wraps up anodal carbon bag 7.In existing quadrate lithium battery internal structure, shown in Figure 2 as the schematic diagram after Fig. 1 and the amplification, anodal carbon bag 7 is cube shaped, and anode collection post 5 inserts the carbon bags and contacts afflux with the carbon bag.This current collection mode is because little with carbon bag contact area, and the current density that can provide is limited.(5～15mA) pulse power supplies or when powering continuously for example can not satisfy it stablizes output current in temperature range-40 ℃～125 ℃ requirement fully at the big electric current of needs.
Summary of the invention
Goal of the invention of the present utility model provides a kind of square lithium/thinly chloride battery that big pulse current output can be provided under broad temperature range-40 ℃～125 ℃.
The utility model is achieved by following technical proposals: a kind of square lithium/thinly chloride lithium battery, and this lithium battery anode, in the part of inside battery, its part-structure is coiled sheet type pole piece.
On the basis of technique scheme, the negative pole of this lithium battery, in the part of inside battery, its part-structure also can be the coiled sheet type pole piece that matches with corresponding anode pole piece.
Adopt technique scheme, can obtain following good effect: by adopting the sheet type pole piece in the technical program, wire netting current collection mode (for example nickel screen, stainless (steel) wire etc.) increases catchment area, improves the large current load ability of battery.Or according to actual electricity consumption needs, bigger load capacity can be by increasing the positive and negative electrode contact area, and both positive and negative polarity all adopts the sheet type pole piece, the takeup type structure.The enforcement of this scheme can improve the load capacity of lithium battery, particularly can improve the output capacity of lithium battery under low temperature-40 ℃.
The technical program is applicable to quadrate lithium battery.The length and width side size range of quadrate lithium battery is at 1.0～200.0mm, and altitude range is at 1.0～300.0mm.
