As shown in Figure 1, general button cell comprises anode coat, negative current collector, negative pole, barrier film, electrolyte, O-ring seal, positive pole, plus plate current-collecting body, anodal shell; A collector is wherein all arranged between both positive and negative polarity and the shell.
Original button lithium battery technology, the pattern of its positive electrode structure.
Fig. 2: the positive pole that collector is only arranged: anodal embedding stainless (steel) wire or anodal shell are coated with conducting resinl only as the collector effect.
Fig. 2 a: universal positive pole, stainless (steel) wire is as collector on it, and the metalolic network in length and breadth that is pressed in the positive powder has increased catchment area and electric conductivity.
Fig. 2 b: on Fig. 2 a basis, the stainless steel currect collecting net is pressed into ripple glaze to increase catchment area.
Fig. 2 c: do not have collector on the anode, on anodal outer casing inner wall, coat conducting resinl, reach the afflux effect.Word shell plane was prone to form arc when cause was sealed, and caused shell and anodal loose contact.
Fig. 2 d: anodal identical with Fig. 2 c, and on the anode cover inwall, put the sheet metal of burn-oning, and coat conducting resinl, with the deformation defect of compensation image 2c.
Fig. 3: ring is solid anodal: the anode ring of ring-type plays and prevents anodal radial expansion effect, and stainless (steel) wire plays the collector effect.It is a kind of positive pole of simple combination.
