積重したシート状電極体を渦巻状に巻回して作ったスパ
イラル状の発電要素を用い、またこの発電要素を構成す
るスパイラル電極から取り出したリード板を電池缶ある
いは端子板などに電気的に接続する構造が採られる。<Conventional technology> Batteries such as spiral-shaped lithium batteries and nickel-cadmium storage batteries use spiral-shaped power generation elements made by spirally winding sheet-shaped electrode bodies in which a positive electrode and a negative electrode are stacked with a separator interposed in between. In addition, a structure is adopted in which a lead plate taken out from the spiral electrode constituting the power generation element is electrically connected to a battery can or a terminal plate.
これらの電池に用いる電極、例えばスパイラル形リチウ
ム電池に用いられる正極において、この正極に上記電流
取出し用のリード板を接続する場合、従来は次のような
手順が用いられている。When connecting the lead plate for taking out the current to the electrode used in these batteries, such as the positive electrode used in a spiral type lithium battery, the following procedure has conventionally been used.
即ち、エクスパンデッドメタル等の全面に孔を形成した
多孔性金属薄板で作った集電体の両面に正極合剤を塗着
し、また乾燥して、集電体に合剤を保持させた帯状体を
作る。次いでこの帯状体をローラなどで圧して正極合剤
を圧縮した後、電池型式に応じた所定寸法に裁断する。That is, a positive electrode mixture was applied to both sides of a current collector made of a porous thin metal plate with holes formed on the entire surface of expanded metal, etc., and then dried to retain the mixture on the current collector. Make a strip. Next, this strip is pressed with a roller or the like to compress the positive electrode mixture, and then cut into a predetermined size depending on the battery type.
その後、第３図（Ａ）の通り、帯状体の所定部位におい
て、上端から下端までの間の集電体表裏面の正極合剤１
７を一定幅でかき取るなどして除去し、集電体１８の表
面を露出させる。その後、第３図（Ｂ）の通り、この露
出面に電流取出し用のリード板１９を位置させ、また一
対の溶接電極をそれぞれ表裏から押し当て、リード板１
９を正極集電体１８に溶接する。Thereafter, as shown in FIG. 3(A), at a predetermined portion of the strip, the positive electrode mixture 1 is applied to the front and back surfaces of the current collector between the upper end and the lower end.
7 is removed by scraping off a certain width to expose the surface of the current collector 18. Thereafter, as shown in FIG. 3(B), a lead plate 19 for taking out the current is placed on this exposed surface, and a pair of welding electrodes are pressed against each other from the front and back sides of the lead plate 19.
9 is welded to the positive electrode current collector 18.
更に、このままでは発電要素巻回時ないし巻回後におい
てリード板１９の露出部などがセパレータを突き破って
負極とショートする危険性があるため、通常はリード板
及び集電体露出部分並びにその周辺部分を覆うように耐
電解液性の絶縁テープ２０（保護テープ）を表裏面から
貼り付け、最後に真空乾燥して水分を完全に除去する。Furthermore, if this continues, there is a risk that the exposed parts of the lead plate 19 will break through the separator and short-circuit with the negative electrode during or after winding the power generation element, so normally the exposed parts of the lead plate, current collector, and their surrounding areas are An electrolyte-resistant insulating tape 20 (protective tape) is applied from the front and back sides so as to cover it, and finally, the moisture is completely removed by vacuum drying.
〈発明が解決しようとする課題〉

の分放電容量上の損失となる。保護テープを貼着する構
造とした場合はこのテープを貼着した部分にある合剤も
反応に関与せず、この度合いがより大きい。<Problems to be Solved by the Invention> However, in the conventional manufacturing method described above, the mixture is scraped off in a constant width from the upper end to the lower end of the electrode, so this scraped part of the electrode is not susceptible to discharge. There is no contribution, and this results in a corresponding loss in discharge capacity. In the case of a structure in which a protective tape is attached, the mixture in the area where the tape is attached also does not participate in the reaction, and the degree of this reaction is greater.
