Embodiment
In the present invention, welding has following three faces at the terminal of keeping off on the battery container of substrate 1: join and parallel A face with this battery container plane; With the A face continuously and not at conplane B face towards the cell thickness direction; And with the B face continuously and not on same plane and towards with the above-mentioned A face C face that is same parallel direction.
Here, so-called same parallel direction is meant that A face and C face exist with respect to two spaces that face distinguished that contain the B face on the same space direction.The A face does not need parallel with the C face especially.
The shape of this terminal need not special qualification, and for example, comprising the whole section of A-B-C is the shape of approximate コ shape.At this moment, whether the length of A face on the section and C face is identical unimportant.In addition, the vertical height of preferred B face is than the height height of this battery protuberance, and then preferably than the height height of battery, still, if too high, the whole height of the sub-battery of band edge will uprise.Under situations such as balance on the consideration size and heat seal strength, the vertical height of B face is preferably welding about the section poor+cell thickness ± 200 μ m near the terminal on the battery container of substrate.
In the present invention, welding is near the terminal on the battery container of substrate 2, preferred welding the face on the battery container and and the face of substrate ground connection between have at least a section poor.Section difference so-called and terminal is meant the ground plane and the vertical range of welding between the face on the battery container of terminal 2.
The section extent is not done special qualification, it is better to be located at 200～500 μ m, it be the reasons are as follows: the section difference was than 200 μ m hours, the distance of C face of keeping off the battery container of substrate and the terminal of welding on this battery container is short, so after having carried out the backflow weld job, in case the C face of the battery container of substrate and the terminal of welding on this battery container of keeping off can be owing to directly contact short circuit or the wlding by the fusion possibility that causes short circuit uprise.
In addition, if when 500 μ m are above, because the increase of the height dimension of the sub-battery of band edge, so inadvisable.If this terminal section of not having is poor, welding can not enter substrate and near the gap between the battery container of substrate, consequently the sub-battery of band edge area occupied on substrate strengthens at the C face on the battery container of another basal disc kept off.
In the present invention, the position of terminal 1 and terminal 2 relation is unimportant.In order to prevent the short circuit between the terminal, it is desirable that terminal 1 and terminal 2 are 180 degree angle ground configurations, and still according to the spatial form of substrate, terminal 1 and terminal 2 for example also can be an angle of 90 degrees configuration.In this case, can seal the コ font peristome of terminal 1, adopt so-called approximate square shape.
Terminal material used in the present invention, if the general metal material that uses just needn't limit especially, but preferred various stainless steel materials, nickel material, dilval, the copper etc. of using.The thickness of terminal does not limit especially, but under the situation of the thickness of 50～300 common μ m, it is preferred setting the welding condition easily.In addition, at least on the face of terminal and substrate ground connection,, carried out the coating of wlding etc. in order to keep the sufficient adhesion strength of the sub-battery of substrate and band edge.
In the present invention, welding has on the B face under the situation of peristome at least at the terminal of keeping off on the battery container of substrate 1, and the sub-battery of band edge is compared with the situation of carrying out mounted on surface on substrate, and area occupied just can be dwindled.The vertical height Lb of this peristome, with respect to the battery container height H of the bigger side of diameter in anodal housing and the negative battery housing, it is just passable to satisfy Lb＞H at least, but preferably with respect to cell height Hc, preferred Lb＞Hc.In this case, can be below the radius R of battery cell from the peristome of B face to the distance R b at battery center, the sub-battery of band edge shared area on substrate just can reduce thus.
In addition, peristome also can be and A face and/or the consecutive peristome of C face.In this case, and then the opposing party end of the non-B face side of A face and/or C face can not sealed separately yet.When the opposing party end of the non-B face side of C face is not sealed,,, can not make intensity decreases and the welding that can reflux owing to 3 ground connection though the area that joins with substrate reduces.
Generating element of the present invention does not take energy to the outside so long as can store electrochemical energy, just be not particularly limited, once, the kind of secondary is unimportant, if but the organic electrolysis battery that preferred electrolyte is made up of non-proton property solvent is handled in the welding of considering to reflux.
For example, have anodal with manganese dioxide and negative pole with the lithium primary battery of lithium metal, anodal with manganese oxide and negative pole uses porous carbon material as active carbon or the organic class electric capacity of coalescence benzene (polyacene) organic semi-conductor, other niobium oxide-lithium alloy class, manganese oxide-lithium titanate class or the like with 3V level battery, the positive and negative level of the manganese lithium alloy class of lithium-aluminium alloy or Si oxide or manganese Si oxide class etc.
Generating element shape of the present invention does not limit especially, for example can be to make the positive pole and the relative shape of negative electrode of sheet by soaking the spacer that has contained electrolyte, and in this case, it is more not contact another electrode surface of spacer and situation that shell joint touches.
This generating element also can unroll by banded positive pole and the negative electrode that spacer will be formed on the collector body of paper tinsel or net etc. in addition, the most peripheral of band electrode part and anodal housing and/or negative electrode casing inner body surface directly contact and airtight like this, and be easy in the operation.
Be used for anodal housing of the present invention and negative pole housing, then needn't be particularly limited if be used for the metal material of general battery, but good various stainless steel materials such as preferred corrosion resistance and anti-pitting.
In addition, in order to make these anodal housings and the not short circuit of negative pole housing, generating element and external environment are cut off, in order to keep confidentiality and fluid tightness, generally be to carry out pressurization such as joint filling by sealing gasket.
As the material that is used for seal Backing material, can be for example polyether-ether-ketone, polyphenylene sulfide, fluororesin etc., also can use to improving forming property and add the material that glass fibre is shaped as required.
