Gargajiya Leclanche’ Battery

A cikin karkashin Leclanche’ battery mai yadda a sattuka da ke faruwa a kan yanki na da abubuwan gargajiya masu haka.

1. Kwakwa mai kyau a zafi ne a kan zinc, ya yi aiki a matsayin anode kuma ya jagoranci duka abubuwan matsalolin da kuma electrolyte na battery.
   Zinc da ake amfani da shi a cikin battery idan ya fi shi da ingantaccen tsari 99.99%. Amma, zinc da ake amfani da shi don bincike kwakwa a zinc-carbon battery tana da cadmium 0.03 zuwa 0.06% da lead 0.02 zuwa 0.04%. Lead ya ba zinc da kyau ga tsarin, kuma tana da muhimmanci wajen rarraba gida, saboda haka, cadmium tana ba zinc da kyau ga resistance.
   Zinc da ake amfani da shi a zinc carbon battery tana da kyau ga kusa da nisa kamar cobalt, copper, nickel, iron saboda waɗannan abubuwa suna da rawar addinin zuwa zinc a cikin electrolyte. Iron tana da zaƙo ga zinc. Antimony, arsenic, magnesium tana da ƙaramin zinc.

2. Abubuwan cathode tana da manganese dioxide. Manganese dioxide tana haɗa da acetylene black da ammonium chloride electrolyte, tana ƙasa a cikin makina mai ƙasa don bayar da tsarin bobbin.
   Bobbin tana yi aiki a matsayin electrode mafi yawan battery. Powdered manganese oxide (MnO2) da powdered carbon black tana haɗa da ruwa, ammonium chloride (NH2Cl) ko/da zinc chloride (ZnCl2). A nan, MnO2 tana da muhimmanci wajen cathode, amma tana da tsari mai girma, saboda haka, carbon black powder tana ƙara tsarin cathode. Saboda carbon dust tana da kyau ga juyin ruwa, tana da muhimmanci wajen ƙara electrolyte a cikin bobbin. Tushen MnO2 da carbon tana iya ƙare da 3:1 zuwa 11:1 ta tsarin battery. Wannan tushen tana iya ƙare da 1:1 idan battery tana gina don flash of cameras saboda a nan ayyukan current tana da muhimmanci da maɗadin.

   
   

   Akawo kamar-kamar da ake amfani da su a dry zinc-carbon battery.

   A baya ake amfani da graphite a matsayin conductive media na cathode bobbin, amma a yanzu ana amfani da carbon black saboda tana da alamar tushen electrolyte mai ruwa da tana ba da kyau ga tsarin cathode mix. Cells da ke da carbon acetylene black a cikin cathode mix su tana da kyau ga inseminated services, amma cells da ke da graphite a cikin cathode mix su tana da kyau ga high and continuous current operation.

1. Natural Manganese Dioxide (NMD) tana samun a natural ore. Waɗannan ores tana da 70 zuwa 85% manganese dioxide. Tana da alpha da beta phase crystal structure.

2. Chemically Synthesized Manganese Dioxide (CMD) tana da 90 zuwa 95% pure manganese dioxide. Tana da delta phase crystal structure.

3. Electrolytic Manganese Dioxide (EMD). EMD tana da mahimmanci wajen performance, amma tana da ƙarfin kayan battery, kuma ake amfani da shi a heavy duty industrial applications. Tana da gamma phase crystal structure.

3. Carbon rod tana saka a cikin cathode bobbin, a matsayin current collector. Yakin carbon rod tana yi aiki a matsayin terminal mafi yawa na cell.
   

   
   

   Ana ƙasa carbon rod a cikin compressed carbon. Tana da ƙarfi mai tsari. Carbon tana da kyau ga porous. Ana yi wax da oil treatment don carbon tana ƙara porous, saboda haka tana ƙara electrolyte mai ruwa, amma tana ƙara gases. Ana yi hakan don hydrogen da carbon dioxide gases da aka faru a cikin battery za su fito a matsayin carbon rod. Gases tana da hanyar porous path don fito saboda upper portion of the bobbin tana ƙasa a asphalt. Ya ni carbon rod a zinc carbon battery tana yi aiki a matsayin venting passage.

4. Anode da cathode tana ƙasa da thin layer of cereal paste wet with ammonium chloride and zinc chloride electrolyte or starch or polymer coated absorbent Kraft paper. Thin separator tana ƙara internal resistance.
   A commonly used Leclanche’ cell tana da electrolyte mai ruwa ammonium chloride da zinc chloride. Amma, a zinc chloride cell tana da electrolyte mai ruwa zinc chloride. Idan small quantity of ammonium chloride tana iya ƙara zinc chloride, don ƙara performance.

5. A fadami cathode bobbin tana da supporting washer (nonconductive).

6. Asphalt seal tana ƙasa a fadami washer, kuma a fadami asphalt seal tana da wax seal.
   Sealing arrangements tana ƙara evaporation of electrolyte and water a service da storage life na battery.

7. A fadami sealing arrangement tana da washer don ƙara sealing material.

8. Washer tana ƙasa one piece metal cover, fitted on top of the carbon rod.

9. Idan assembly tana ƙasa da metallic, paper ko plastic jacket don bayar da tsarin. Labels da ratings tana rubuta a outer cover na cell.

10. Fadami cell tana ƙasa da steel cover don ƙara protection.
