Description

Oppfinnelsen vedrører en fremgangsmåte ved fremstilling av et batteri bestående av på hverandre stablede flatceller inneholdende en zinkanode, en alkalisk elektrolytt og en katode i form av en brunsten-karbonbrikett, som er i kontakt med en metallterminal, slik sam angitt i krav l's ingress. The invention relates to a method for producing a battery consisting of stacked flat cells containing a zinc anode, an alkaline electrolyte and a cathode in the form of a brownstone carbon briquette, which is in contact with a metal terminal, as stated in the preamble of claim 1.

De kjente 9V-batterier med en høyde på ca. 40 mm består The familiar 9V batteries with a height of approx. 40 mm consists

av et antall forholdsvis lange og smale sylindriske elementer. Disse elementer er forholdsvis vanskelige å fremstille, svarende til at kassasjonsprosenten er forholdsvis høy. Dertil,kommer at en stor del av volumet er uutnyttet og at man forøvrig er bundet med hensyn til dimensjonene. of a number of relatively long and narrow cylindrical elements. These elements are relatively difficult to produce, corresponding to the fact that the rejection rate is relatively high. In addition, a large part of the volume is unused and that you are otherwise restricted with regard to the dimensions.

Man er derfor gått over til å anvende flatceller som er stablet på hverandre - jfr. f.eks. dansk patentansøkning nr. 53i8/78. Derved oppnås en: 22%'s bedre utnyttelse av volumet. Den enkelte celle er. innkapslet i et plastbeger. Et særlig problem er imidlertid å,; skape eri tilfredsstillende kontakt mellom brunsten-karbohbriketter (katodemassen) og den pågjeldende metallterminal. One has therefore switched to using flat cells that are stacked on top of each other - cf. e.g. Danish Patent Application No. 53i8/78. Thereby a: 22% better utilization of the volume is achieved. The individual cell is. encased in a plastic cup. A particular problem is, however, to; create a satisfactory contact between the brownstone carbon briquettes (cathode mass) and the relevant metal terminal.

Ifølge oppfinnelsen er det anvist hvorledes det på en enkel måte vil kunne etableres en 'tilfredsstillende kontakt mellom brunsten-karbonbriketten og metalltermihalen, og dette formål blir ifølge oppfinnelsen oppnåd ved at brunsten-karbonbriketten fastgjøres til den negative metallterminal ved.klemvirkning langs metallterminalens kanter, fortrinnsvis langs to motstående kanter. Derved blir batteriet samtidig egnet for masseproduksjon, idet brunsten-karbonbriketten vil da kunne skytes inn fra siden av den langs to motstående•kanter ombukkete terminalplate. Fremgangsmåten er særpreget ved det som er angitt i krav l's karakteriserende del. Ytterligere trekk fremgår av kravene 2 og 3. According to the invention, it is indicated how a satisfactory contact between the lignite-carbon briquette and the metal thermal tail can be established in a simple way, and this purpose is achieved according to the invention by attaching the lignite-carbon briquette to the negative metal terminal by a clamping action along the edges of the metal terminal, preferably along two opposite edges. This makes the battery suitable for mass production at the same time, as the brownstone carbon briquette will then be able to be inserted from the side of the bent terminal plate along two opposite • edges. The method is characterized by what is stated in claim 1's characterizing part. Further features appear from requirements 2 and 3.

For å lette den sideveis innføring av brunstens-karbonbrikettene kan disse med fordel være avrundet i hjørnene. Foråt brunsten-karbonbrikettene skal kunne utvide seg, er de ved innføringen ca. 0,06-0,08 mm smalere enn metallterminalen. To facilitate the lateral introduction of the brownstone carbon briquettes, these can advantageously be rounded in the corners. Before the brown stone carbon briquettes can expand, they are approx. 0.06-0.08 mm narrower than the metal terminal.

Oppfinnelsen skal nærmere forklares i det følgende under hen-visning til tegningen hvor The invention will be explained in more detail in the following with reference to the drawing where

fig. 1 viser en del av et batteri, idet man ser en gjennom-føring til en metallterminal som er i kontakt med en brunsten-karbonbrikett, og fig. 1 shows part of a battery, seeing a lead-through to a metal terminal which is in contact with a brownstone carbon briquette, and

fig. 2 er selve metallterminalen. fig. 2 is the metal terminal itself.

Det i fig. 1 viste alkaliske batteri består av et antall på hverandre stablede flatceller. Den enkelte celle inneholder en zinkanode, en alkalisk elektrolytt og en katode i form av en brunsten-karbonbrikett 1. Det skal imidlertid tilveiebringes en tilfredsstillende kontakt mellom brunsten-karbonbriketten 1 og metallterminalen 2, idet denne forbindelse er bestemmen-de for kortslutningsstrømmen. Hvis man anvendte en firkantet terminal med ombukninger langs alle fire kanter, ville ombuk-ningene bue utad og forbindelsen bli utilstrekkelig. Ifølge oppfinnelsen er det blitt gjort bruk av et bukket metallstyk-ke - se fig. 2 - med ombukninger langs to motstående kanter, hvilke ombukninger vender ca. 1-3° innad. Derved oppstår en tilstrekkelig god fastklemming av brunsten-karbonbriketten 1. Terminalen 2 skal selvfølgelig være av et tilpasset fjær-ende materiale, så som forniklet jern. Man får derved en kortautningsstrøm på 3-5A. I de tidligere rundceller hadde man slett ikke dette problem, idet den pågjeldende elektro-masse ble innført under trykk og derved tilveiebragte den nødvendige kontakt, idet man utnyttet at det sylindriske legeme var istand til å oppta det pågjeldende trykk uten at det gikk ut over kontakten. That in fig. 1 shown alkaline battery consists of a number of stacked flat cells. The individual cell contains a zinc anode, an alkaline electrolyte and a cathode in the form of a lignite-carbon briquette 1. However, a satisfactory contact must be provided between the lignite-carbon briquette 1 and the metal terminal 2, as this connection is decisive for the short-circuit current. If one used a square terminal with bends along all four edges, the bends would curve outwards and the connection would be insufficient. According to the invention, use has been made of a bent piece of metal - see fig. 2 - with folds along two opposite edges, which folds turn approx. 1-3° inwards. This results in a sufficiently good clamping of the brownstone carbon briquette 1. The terminal 2 must of course be of a suitable spring-end material, such as nickel-plated iron. This results in a short-circuit current of 3-5A. In the earlier round cells, this problem was not at all present, as the electro-mass in question was introduced under pressure and thereby provided the necessary contact, as they took advantage of the fact that the cylindrical body was able to absorb the pressure in question without it going beyond the contact .

Metoden ifølge oppfinnelsen er dessuten egnet til massefrem-stilling, idet terminallegemet er symmetrisk og brunsten-karbonbrikettene vil kunne skytes inn fra siden når de kun er avrundet i hjørnene. The method according to the invention is also suitable for mass production, as the terminal body is symmetrical and the lignite carbon briquettes will be able to be shot in from the side when they are only rounded at the corners.

Terminalen er eventuelt utstyrt med en ytterligere ombukning 4, idet man derved også vil kunne oppnå en viss kontakt ved bunnflaten. Brikettene har en bredde som er ca. 0,06-0,08 mm mindre enn terminalen, idet det derved tas hensyn til at brikettene utvider seg en smule som følge av at det frigjøres spenninger ved elektrolyttilsetning. The terminal is optionally equipped with a further bend 4, as it will also be possible to achieve a certain contact at the bottom surface. The briquettes have a width of approx. 0.06-0.08 mm smaller than the terminal, thereby taking into account that the briquettes expand a little as a result of voltages being released when electrolyte is added.

I en konkret utforming har terminalen en høyde på 2,7 mm, en lengde på 17,5 mm og en bredde på 13,08 mm. Materialtykkel-sen er ca. 0,1-0,3 mm. In a concrete design, the terminal has a height of 2.7 mm, a length of 17.5 mm and a width of 13.08 mm. Material thickness is approx. 0.1-0.3 mm.
