Abstract
Title: A Method of Manufacturing a Battery A b s t r a c t A method of manufacturing a flat cell comprising a zinc anode, an alkaline electrolyte, and a cathode in the form of a briquette of manganese dioxide-carbon being in contact with a metal terminal. According to the invention the briquette of manganese dioxide-carbon is secured to the negative metal terminal through squeezing along two oppos-ing and bent flaps of the metal terminal. In this manner a satisfactory contact between the briquette of manganese di=
oxide-carbon and the metal terminal is provided at the same time as a battery comprising several cells is suited for mass production, said briquette of manganese dioxide-carbon may be introduced from the side of the terminal plate bent along two opposing edges. The terminal plate need only be bent slightly more than 90°.

Description
~ ~ ~5~3~
The inventlon relates to a method of manufacturing a battery comprising flat cells piled on each other and including a zinc anode, an alkaline electrolyte, and a ca-thode in the form of a briquette of manganese dioxide-carbon, said briquette being in contact ~-~ith a metal terminal.
The known 9V ba-tteries of a height of about ~0 mm comprise a plurality of preferably long and narrow cylindrical members. These members are rather difEicult to manufacture, i.a. the scrapping percentage is rather highO In addition, the major portion of the volume is not utilized and the dimensions are subject to limits.
Flat cells have therefore been introduced, which are piled on each other, cf. for instance Danish patent application No. 531~/78, publlshed May 2~, l9i30. In this manner a 28~
higher utilization of the volume is obtained. Each cell is encased in a plastic cup. However, a particular problem exists in producing a satisfactory contact between the briquette of mangane~e dioxide-carbon (the cethcde mass) and the m~tal terminal in question.
According to the invention it is shown how it is possible in a simple manner to produce a satisfactory contact between the briquette of manganese dioxide-carbon and the metal terminal, and this object is according to the invention obtained by the briquette of manganese dioxide~carbon being secured to the negative metal terminal through squeezing along the edges of said metal terminal, preferably along two opposing edges. In this manner the battery is simultaneously suited for mass production since the bri-mg/ ~- - 2 -3~
quette of manganese dioxide-carbon then may be clisplaced from the side of the terminal plate hent along two opposing edges. The terminal plate need only be bent slightly more, preferably 1~3, than 9o along two opposin~ edges.
In order to -Eacilitate the introduction fxom -the side of the briquettes of manganese dioxide-carbon, said bri-quettes are pre~erably rounded a-t the corners.
~ince the briquettes of manganese dioxide-carbon must be able to extend, they are about 0.06-0.08 mm narrower than the metal terminal at their introduction.
The invention will be described below with reference to the accompanying drawing, in which Fig. l illustrates part of a battery, whereby a lead-in to a metal terminal appears, said metal terminal being in contact with a briquette of manganese dioxide-carbon, and Fig. 2 illustrates the metal terminal.
The alkaline battery illustrated in Fig. l comprises a plurality of flat cells piled on each other. Each cell com-prises a zinc anode, an alkaline electrolyte, and a cathodein the form of a briquette l of manganese dioxide-carbon.
The briquette of manganese dioxide-carbon is in contact with a metal terminal 2. A satisfactory contact between the bri-quette l of manganese dioxide-carbon and the metal terminal

The invention will be described below with reference to the accompanying drawing, in which Fig. l illustrates part of a battery, whereby a lead-in to a metal terminal appears, said metal terminal being in contact with a briquette of manganese dioxide-carbon, and Fig. 2 illustrates the metal terminal.
The alkaline battery illustrated in Fig. l comprises a plurality of flat cells piled on each other. Each cell com-prises a zinc anode, an alkaline electrolyte, and a cathodein the form of a briquette l of manganese dioxide-carbon.
The briquette of manganese dioxide-carbon is in contact with a metal terminal 2. A satisfactory contact between the bri-quette l of manganese dioxide-carbon and the metal terminal
2 must~ however, be provided since this con-tact determines the short-circuit current. By a quadrangular terminal with . . .
flaps along all four edges, said flaps would curve outwards and involve an insufficient electric connection. According to the inven-tion a bent me-tal part is used, cf. Fig. 2, comprising flaps along two opposing edges, said flaps fac ing about 1-3 inwards. In this manner a sufficiently good squeezing of the briquette 1 of manganese dioxide-carbon is obtained. The terminal 2 must, of course, be of a suffi-ciently resilient material such as nickel-iron. As a result a short-clrcuit current of 3-5 A is obtained. The previous round cells were not encumbered with this problem since the electrode mass in question was introduced under a pressure providing the necessary contact, and since a cylindrical member is able to receive the pressure in question without damaging the contact.
The method according to the invention is furthermore suited for mass production since the terminal body is sym-metrical and the briquettes of manganese dioxide-carbon may be introduced from the side when they are rounded at the corners.
The terminal is op-tionally provided with an additional flap 4, thereby providing a predetermined contact at the bottom surface. The briquettes are of a width of about 0.06-0.08 mm smaller than the terminal recognizing that the briquettes extend slightly when tensions are released by addition of electrolyte. According to an embodiment the ter-minal is of a heigh-t of 2.7 mm, a length of 17.5 mm, and a width of 13.08 mm. The thickness of the material is about 0.1-0.3 mm.
