Lub luag haujlwm ntawm nickel mesh hauv nickel-hlau hydride roj teeb
Nickel-hlau hydride roj teebyog ib tug rechargeable secondary roj teeb. Nws txoj haujlwm ua haujlwm yog khaws cia thiab tso tawm hluav taws xob los ntawm cov tshuaj tiv thaiv ntawm cov hlau nickel (Ni) thiab hydrogen (H). Cov nickel mesh hauv NiMH roj teeb ua si ntau lub luag haujlwm tseem ceeb.
Nickel mesh feem ntau yog sivRaws li cov khoom siv hluav taws xob hauv cov roj teeb nickel-hlau hydride, thiab nws tiv tauj cov electrolyte los ua ib qho chaw rau cov tshuaj tiv thaiv electrochemical. Nws muaj cov khoom siv hluav taws xob zoo heev thiab tuaj yeem hloov cov tshuaj tiv thaiv electrochemical hauv lub roj teeb mus rau hauv cov dej ntws tam sim no, yog li paub txog cov khoom siv hluav taws xob.
Nickel hlau mesh kuj muaj kev ruaj ntseg zoo. Thaum lub sij hawm lub roj teeb them thiab tshem tawm cov txheej txheem, cov nickel xaim mesh tuaj yeem tswj tau qee yam zoo li thiab qhov ruaj khov thiab tiv thaiv cov teeb meem kev nyab xeeb xws li hauv luv luv Circuit Court thiab tawg ntawm lub roj teeb. Nyob rau tib lub sijhawm, nws cov qauv ntxeem tau pab cov electrolyte kom sib npaug sib npaug thiab nkag mus, txhim kho lub roj teeb ua haujlwm tau zoo.
Ntxiv rau, nickel hlau mesh kuj muaj qee yam catalytic nyhuv. Thaum lub sij hawm lub roj teeb them thiab tshem tawm cov txheej txheem, cov catalytically active tshuaj nyob rau saum npoo ntawm cov npib tsib xee mesh tuaj yeem txhawb cov tshuaj tiv thaiv electrochemical thiab txhim kho kev them nyiaj thiab kev tawm dag zog thiab kev pab cuam lub neej ntawm lub roj teeb.
Qhov porosity thiab siab tshwj xeeb ntawm thaj chaw ntawm npib tsib xee mesh kuj muab nws nrog kev ua tau zoo heev raws li cov khoom siv electrode. Qhov no tso cai rau ntau qhov chaw reactive hauv lub roj teeb, ua kom lub zog ceev thiab lub zog ceev ntawm lub roj teeb. Nyob rau tib lub sijhawm, cov qauv no tseem pab kom nkag mus ntawm electrolyte thiab diffusion ntawm cov pa roj, tswj kev ua haujlwm ruaj khov ntawm lub roj teeb.
Los xaus, cov nickel mesh hauv nickel-hlau hydride roj teeb ua lub luag haujlwm tseem ceeb. Raws li cov khoom siv electrode, nws muaj kev ua tau zoo heev, kev ruaj ntseg thiab cov nyhuv catalytic, uas txhawb cov txheej txheem electrochemical hauv cov roj teeb. Cov yam ntxwv no ua rau cov roj teeb uas tsis muaj rwj Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis, kev ua haujlwm thiab daim ntawv thov ntawm nickel-hlau hydride roj teeb yuav raug nthuav dav ntxiv thiab txhim kho.
