Cov hlwb qhuav, xws li alkaline AA lossis AAA roj teeb, cia siab rau graphite raws li ib qho tseem ceeb ntawm lawv cov electrodes. Hauv cov kev cog lus no, cov duab hluav taws xob, graphite pabcuam ua cathode (zoo kawg ultrasonic, ua rau muaj kev cia siab ultrasonic}}} lub zog cia.
Graphite cov haum rau cov hlwb qhuav stems los ntawm nws cov khoom ntiag tug. Ua ntej, nws cov hluav taws xob siab ua kom nruj ceev hluav taws xob hluav taws xob ntws ntawm cov Cathode thiab anode (feem ntau zinc), feem ntau zinc), ua kom nruj zog. Thib ob, graphite yog cov inert nyob rau hauv alkaline electrolyte (potassium hydroxide), tiv thaiv cov kev tsis txaus siab uas tsis muaj roj teeb. Qhov thib peb, nws tus nqi qis thiab muaj ntau ua nws cov kev xaiv ua rau huab hwm coj ntau lawm.
Hauv cov qe qhuav alkaline, lub graphite cathode feem ntau yog coated mus rau cov hlau tuaj yeem, tsim cov qauv cylindrical. Thaum lub sijhawm tso tawm, zinc (anode) oxidizes, tso cov hluav taws xob uas taug kev los ntawm cov cathoe graphe. Manganese dioxide (mnoose) hauv catale reacts nrog cov hluav taws xob thiab cov protons los ntawm electrolyte, tsim hluav taws xob lub zog. Graphite cov qauv txheej txheem txhim kho mnoo ₂ adsorption, nce cov tshuaj tiv thaiv kev ua haujlwm thiab ncua txee lub neej.
Piv rau lwm cov ntaub ntawv canhode (piv txwv li, hlau oxides), graphite cov conductivity thiab nyob ruaj khov outperform. Piv txwv li, graphite - raws li lawv lub peev xwm tom qab 5}}}} oxide kev xaiv degrade sai dua. Qhov kev ntseeg tau no ua rau graphite cov khoom siv ntawm kev xaiv rau cov hlwb qhuav, muaj kev tiv thaiv txhua yam los ntawm cov teeb meem chaw taws teeb tswj thoob ntiaj teb.
Cim npe nrov: Graphite yog siv rau cov electrode hauv cell qhuav, Tuam Tshoj graphite yog siv rau cov electrode chaw tsim tshuaj paus, lwm tus neeg, Hoobkas
