Qhov Tseem Ceeb Qhov Sib Txawv - Cov Cells Tseem Ceeb thiab Thib Ob
Roj teeb yog siv thaum xav tau lub zog hluav taws xob. Lawv sib sau thiab muab cov nqi hluav taws xob ua hluav taws xob thaum nws xav tau. Cov roj teeb muaj xws li cov thawj lossis cov hlwb thib ob. Qhov sib txawv tseem ceeb ntawm cov hlwb thawj thiab theem nrab yog qhov rov siv tau dua. Cov hlwb thib ob tuaj yeem rov qab siv dua thiab rov siv dua thaum lub hlwb thawj zaug tsuas yog siv tau ib zaug xwb. Lub hom phiaj thiab kev thauj khoom txuas nrog lub roj teeb nyob ntawm seb hom cell sab hauv. Tej zaum yuav muaj ib lossis ntau lub hlwb ntawm ib hom hauv ib lub roj teeb; yog li ntawd txiav txim siab qhov voltage, los yog nyob rau hauv lwm yam lus, lub electromotive quab yuam (EMF) ntawm lub roj teeb. Txhua lub cell muaj 3 qhov loj; xws li Anode, Cathode, thiab Electrolyte.
Primary Cells yog dab tsi?
Cov hlwb tseem ceeb siv tau ib zaug thiab muab pov tseg. Lawv tsis tuaj yeem raug them rov qab thiab rov siv dua. Daim ntawv lo ntawm lub xov tooj tseem ceeb ib txwm hais tias nws yuav tsum tsis txhob rov them dua vim tias nws muaj kev phom sij rau kev sim rov qab thiab tej zaum yuav tawg, yog tias ua li ntawd. Qhuav cell thiab Mercury cell yog cov piv txwv rau cov hlwb tseem ceeb. Cov xovtooj tseem ceeb yog qhov tseem ceeb ntawm cov tshuaj lom neeg thiab tsim hluav taws xob los ntawm cov tshuaj tiv thaiv tsis tuaj yeem. Thaum cov tshuaj tiv thaiv ua tiav, nws tsis tuaj yeem rov tsim dua. Rau ib qho tam sim ntawd, lub cell qhuav yog muaj cov Carbon Cathode nyob ib puag ncig los ntawm NH 4Cl hauv lub thawv Zink. NH4Cl thiab ZnCl2 ua cov electrolyte thaum lub thawv Zinc ua raws li Anode. Ib qho me me ntawm MnO2 kuj sib xyaw nrog cov electrolyte. Cov txheej txheem tshuaj ntawm cov cell qhuav tuaj yeem sau tau raws li hauv qab no;
Zn-->Zn2++2 electron (Anode reaction)
NH4+ + MnO2 + electron -->MnO(OH) + NH3 (Cathode reaction)
Cov hlwb tseem ceeb feem ntau pom thiab siv hauv cov khoom ua si hluav taws xob feem ntau, moos, lub dab teg saib thiab cov chaw taws teeb tswj hauv tsev.
Dab tsi yog Secondary Cells?
Secondary cell kuj yog tshuaj cell tab sis, tuaj yeem rov qab siv dua. Cov tshuaj tiv thaiv uas tsim hluav taws xob yog thim rov qab, thiab lub xov tooj ntawm tes tuaj yeem siv tau los ua ib qho tshiab tom qab cov txheej txheem rov ua dua. Lub xovtooj tuaj yeem rov qab siv tau tab sis lub neej luv luv. Lead-acid thiab LiFe cell yog ib co piv txwv ntawm cov hlwb thib ob. Nyob rau hauv ib tug Lead-acid cell, Lead ua raws li lub anode thiab ib daim phiaj ntawm cov hlau lead packed nrog lead dioxide ua raws li cathode. Sulfuric acid yog sau los ua cov electrolyte. Cov tshuaj tiv thaiv kab mob hauv cov Lead-Acid cell yog muab hauv qab no. Lawv yog cov txheej txheem thim rov qab.
Pb+So42- --->PbSO4 + 2 electron (Cov tshuaj tiv thaiv anode)
PbO2 + 4H+ + SO42- + 2 electron --> PbSO4 + 2H2O (Cathode reaction)
Cov tsheb niaj hnub hybrid yog siv los ntawm roj av thiab hluav taws xob. Lub roj teeb them thaum lub tsheb txav, thiab tom qab ntawd cov khoom siv hluav taws xob khaws cia siv tau los khiav. Tag nrho cov roj teeb pob hauv cov tsheb no yog ua los ntawm cov hlwb thib ob. Lwm qhov kev siv rau cov roj teeb thib ob yog rau kev pib, teeb pom kev zoo, thiab ignition hauv tsheb. Tsis tas li ntawd, lawv tau siv hauv cov khoom siv hluav taws xob tsis cuam tshuam (UPSs), kev sib txuas lus, thiab cov cuab yeej nqa tau yooj yim.
Dab tsi yog qhov txawv ntawm Lub Tsev Kawm Ntawv Qib Siab thiab Qib Ob?
Tus Nqi Zoo:
Siv thawj lub hlwb yog nqi zoo piv rau cov hlwb thib ob, pib.
Tab sis siv cov hlwb thib ob yuav yog kev nqis peev mus ntev vim tias thawj lub hlwb yuav tsum tau hloov los ntawm lwm cov txheej txheem tom qab qee lub sijhawm.
Tus nqi tso tawm tus kheej:
Cov hlwb tseem ceeb tau qis dua tus kheej tso tawm yog li lawv tsim nyog rau cov khoom siv ua haujlwm standby uas xav tau cov dej me me txuas ntxiv mus ntev. Nws yog ib qho tseem ceeb rau sawv cev ntawm cov cuab yeej kev nyab xeeb xws li cov pa luam yeeb / Hluav Taws Xob, tswb tswb thiab moos.
Cov kab mob thib ob muaj qhov tso tawm tus kheej ntau dua.
Nqi thiab Siv:
Cov hlwb tseem pheej yig thiab siv tau yooj yim.
Cov qes thib ob yog kim thiab nyuaj dua hauv kev siv.
