Txoj Kev Cia Zog

Roj teeb lub zog cia
Cov ntawv siv hluav taws xob siab feem ntau yog siv cov roj ntsha lead-acid, feem ntau yog siv los khaws cov khoom siv hluav taws xob ntau tshaj plaws hauv cov khoom siv hluav taws xob thaum muaj xwm ceev, lub tsheb roj teeb, thiab cov chaw tsim hluav taws xob. Kev siv hluav taws xob tsawg kuj tseem tuaj yeem siv cov roj teeb uas siv tau rov qab, xws li cov roj teeb nickel hydrogen, lithium-ion roj teeb, thiab lwm yam.
Txhua lub roj teeb vanadium ntws yog lub zog loj cia roj teeb uas hloov cov tshuaj siv hluav taws xob rau hluav taws xob los ntawm kev hloov pauv hauv lub xeev valence ntawm vanadium ions, yog li khaws cia thiab tso tawm lub zog tsim los ntawm cua lossis hnub ci zog. Nws yog feem ntau hu ua "power bank" hauv kev lag luam. Kev lag luam roj teeb vanadium siv rau lub ncov shaving ntawm cov nroj tsuag hluav taws xob thiab cua zog cia hauv cov teb chaws tsim kho xws li Tebchaws Meskas thiab Nyij Pooj tau tsim sai heev, thiab cov thev naus laus zis tau pib matured. Piv rau lithium roj teeb, qhov zoo tshaj plaws ntawm txhua lub roj teeb vanadium ntws yog tias lawv tsis hlawv lossis tawg.
Inductor zog cia
Tus inductor nws tus kheej yog lub zog cia khoom, thiab cov khoom siv hluav taws xob khaws cia yog proportional rau square ntawm nws tus kheej inductance thiab tam sim no ntws los ntawm nws: E=L * I * I/2. Txij li thaum inductance muaj qhov tsis kam ntawm chav tsev kub, tsis kam siv lub zog, ntau lub zog cia siv superconductors. Inductive zog cia tseem tsis tau paub tab, tab sis kuj muaj cov piv txwv ntawm daim ntawv thov qhia.
Capacitor zog cia
Lub capacitor kuj yog lub zog cia khoom, uas khaws cov hluav taws xob hluav taws xob ncaj qha ncaj qha rau nws tus kheej lub peev xwm thiab cov square ntawm lub davhlau ya nyob twg voltage: E=C * U * U / 2. Capacitive zog cia yog yooj yim los tswj thiab tsis xav tau superconductors. Lwm qhov tseem ceeb ntawm kev khaws cia lub zog capacitive yog nws lub peev xwm los muab lub zog siab sai, uas yog qhov tsim nyog rau kev siv xws li lasers thiab teeb nyem.
Supercapacitors, tseem hu ua electrochemical capacitors, yog ib hom tshiab ntawm cov khoom siv hluav taws xob uas nyob nruab nrab ntawm cov khoom siv hluav taws xob thiab cov roj teeb uas siv tau. Lawv cov qauv zoo ib yam li cov roj teeb, feem ntau suav nrog dual electrodes, electrolytes, cov khoom siv tam sim no, thiab cov khoom sib cais. Lawv muaj qhov zoo xws li lub zog ceev ceev, lub neej voj voog ntev, kev ua haujlwm kub qis, kev nyab xeeb, kev ntseeg tau, thiab kev phooj ywg ib puag ncig. Txawm li cas los xij, vim qhov tsis tshua muaj hluav taws xob tiv taus hluav taws xob thiab muaj cov xau tam sim no, lub zog cia thiab tuav lub sijhawm raug txwv. Tam sim no, supercapacitors feem ntau yog raws li ob txheej txheej capacitors nrog ntxeem tau cov pa roj carbon electrodes / electrolyte interfaces, los yog quasi capacitors generated los ntawm hlau oxides los yog conductive polymers kom ua tau lub zog cia.
