Lithium Ion Supercapacitor

Khoom Taw Qhia

Lub supercapacitor tuaj yeem piav qhia hauv cov ntsiab lus yooj yim raws li tus choj ntawm electrolytic capacitor thiab rechargeable roj teeb. Supercapacitors kuj qee zaum hu ua supercars, ultracapacitors, lossis hluav taws xob ob txheej capacitors. Supercapacitors muaj ntau dua capacitance tus nqi piv rau lwm hom capacitor thiab muaj nyob rau hauv tus nqi ntawm ib feem kaum ntawm Farad mus rau ntau txhiab Farads. Ib leeg, lawv muaj qhov txwv qis dua li cov khoom siv hluav taws xob electrolytic, txog 2 V rau 4 V. Vim tias lawv ua haujlwm electrostatically, lawv tuaj yeem raug them thiab tawm txhua lub sijhawm. Kev koom ua ke ntawm supercapacitors rau hauv kev siv hluav taws xob thiab electromechanical yog loj hlob sai vim yog kev txhim kho hauv volumetric efficiency thiab cov nqi. Kev loj hlob ntawm lub tsheb hluav taws xob (EV) kev ua lag luam uas supercapacitors tau siv rau hauv kev siv zog rov ua dua tshiab, lub zog hluav taws xob luv luv, thiab roj teeb hluav taws xob ruaj khov yog qhov tseem ceeb rau kev loj hlob no.

Cov roj teeb muaj kev lag luam cuam tshuam txog kev ua haujlwm ib puag ncig, qhov loj me, thiab kev nyab xeeb, uas ua rau cov nqi nce thiab txo lawv cov txiaj ntsig. Supercapacitors tuaj yeem daws qee qhov teeb meem no, tab sis lawv tsuas yog tsis muaj lub zog xav tau rau ntau daim ntawv thov. Txhawm rau daws cov kev txwv no, koj tuaj yeem tig mus rau lithium-ion supercapacitor, tseem hu ua hybrid supercapacitor. Lub lithium ion supercapacitor yog ib hom hybrid ntawm capacitor cais raws li hom supercapacitor. Nws yog hu ua hybrid vim hais tias cov anode yog tib yam li cov siv nyob rau hauv lithium-ion roj teeb thiab cov cathode yog tib yam li cov siv nyob rau hauv supercapacitors. Cov pa roj carbon activated feem ntau yog siv los ua cathode. Lub anode ntawm lithium-ion supercapacitor muaj cov khoom siv carbon uas feem ntau pre-doped nrog lithium ions. Cov txheej txheem ua ntej doping no txo ​​qis lub peev xwm ntawm cov anode thiab tso cai rau cov zis hluav taws xob kuj zoo piv rau lwm cov supercapacitors.

Yam khoom

• siab capacitance piv rau ib tug capacitor, vim hais tias ntawm cov anode loj, tab sis muaj peev xwm tsawg piv rau Li-ion cell.
• siab zog ceev piv rau ib tug capacitor (14 W⋅h / kg), tab sis tsawg zog ceev piv rau ib tug Li-ion cell
• siab zog ceev
• kev ntseeg siab
• Kev khiav hauj lwm kub ntawm -20 degree mus rau 70 degree
• qis tus kheej tso tawm (<5% voltage drop at 25 °C over three months)

Daim ntawv thov

Lithium ion supercapacitors yog tsim nyog rau cov ntawv thov uas xav tau lub zog siab ceev, siab zog ceev, thiab ua haujlwm zoo heev. Txij li thaum lawv sib xyaw ua ke muaj zog ceev nrog lub zog siab ceev, tsis tas yuav tsum muaj cov khoom siv hluav taws xob ntxiv hauv ntau hom kev siv, ua rau txo cov nqi. Muaj peev xwm siv tau rau lithium-ion capacitors yog, piv txwv li, hauv thaj chaw ntawm cov tshuab hluav taws xob tsim hluav taws xob, lub tshuab hluav taws xob tsis cuam tshuam (UPS), hluav taws xob sag them, hluav taws xob hluav taws xob photovoltaic, lub zog rov ua haujlwm hauv kev lag luam machinery, hluav taws xob thiab hybrid tsheb, thiab tsheb thauj mus los.
