Kuyamba Kwambiri kwa Battery ya NiMH (Nickel-Metal Hydride Battery)
TheNiMh batirendi mtundu wa batri yachiwiri yofanana ndi batire ya NiCd.Ikhoza kuwonjezeredwa ndipo ingagwiritsidwe ntchito nthawi zambiri.Chifukwa chake, batire ya NiMH ndi mtundu wa batri wokonda zachilengedwe komanso magwiridwe antchito abwino poyerekeza ndi batire yachikhalidwe yamchere kapena batire ya NiCd, ndikupangitsa kuti ilandilidwe bwino pamsika.Mwachitsanzo, mabatire a NiMH amagwiritsidwa ntchito kwambiri pamakamera a digito, mafoni am'manja, makamera, ma shaver, ma transceivers, ndi zida zina zamagetsi.
Muyezo wamakampani pamagetsi ovotera a cell ya NiMH ndi 1.2 volts.M'malo mwake, mabatire a NiMH amagawidwa kukhala mabatire apamwamba kwambiri a NiMH ndi mabatire a NiMH otsika kwambiri.Elekitirodi yabwino ya batire ya NiMH ndi Ni(OH)2 (yomwe imatchedwanso nickel-oxide hydroxide), ndipo electrode yoyipa ya batire ya NiMH imapangidwa kuchokera ku alloy-absorbing alloy.
Mbiri ya Battery ya NiMH (Nickel-Metal Hydride Battery)
Lingaliro la batri la NiMh lidakwezedwa koyamba m'ma 1970, ndi kafukufuku wambiri wokhazikika m'zaka za m'ma 1980 ndi kupanga mafakitale koyamba koyambirira kwa 1990s.Mabatire a NiMH poyamba anali m'malo mwa mabatire a NiCad, kupeŵa kugwiritsa ntchito chinthu chapoizoni 'cadmium' ndikuchotsa zoopsa za chilengedwe zomwe zimayambitsidwa ndi zitsulo zolemera m'moyo wathu watsiku ndi tsiku.Mabatire a NiMH adapangidwa koyamba ku Japan, United States, Germany, ndi mayiko ena.
Kumbali inayi, ndi chitukuko cha betri ya Lithium Ion ndi matekinoloje ena atsopano m'dera la mphamvu zobiriwira, batire ya NiMH pang'onopang'ono inataya kulemera m'madera ena chifukwa cha zovuta zake.Mabatire oyambirira a NiMH ankagwiritsidwa ntchito makamaka m'malo mwa mabatire a NiCd m'makompyuta apakompyuta ndi mafoni a m'manja.Kuyambira malonda a mabatire a Li-ion m'zaka za m'ma 1990, mabatire a Li-ion adalowa m'malo mwa mabatire a NiMH, ndipo atenga msika wa zipangizo zamagetsi zonyamula katundu kwa zaka zoposa khumi kuyambira pamenepo.
Komabe, teknoloji ya NiMH siinakhalebe yokhazikika kusiyana ndi ntchito za ogula, kumene Lithium-ion yasintha kwambiri NiMH.Tekinoloje ya NiMH imachitika pamapulogalamu amagalimoto.Ndiukadaulo womwe umakonda popereka magetsi ku ma HEVs ndipo wapeza zaka 10 zogwiritsa ntchito popanda zovuta.Chifukwa chake, imatha kukhala moyo wonse wagalimoto.Kutentha kwa ntchito kwa maselo a NiMH kwawonjezeka kufika pafupifupi 100 ° C (-30 ° C mpaka + 75 ° C), yomwe ndi yokwera kwambiri kuposa kutentha komwe kuli kotheka kwa maselo a Lithium.Izi zimapangitsa ukadaulo wa NiMH kukhala wabwino kugwiritsidwa ntchito pamagalimoto.Zomwe zimagwira mu NiMH ndizotetezeka mwachilengedwe kuposa zomwe zili m'maselo opangidwa ndi Lithium, ndipo mabatire a NiMH sakhala ndi zokumbukira.Mabatire a NiMH safuna makina oyendetsera mabatire (BMS) omwe amafunidwa ndi mabatire a lithiamu, ndipo amatha kupirira kuchuluka kwamphamvu kwamagetsi amagetsi a EV ndikukhala ndi mankhwala omwe ali otetezeka kwambiri kuposa omwe amapezeka m'maselo a Lithium.Posachedwapa, batire ya NiMH idzagwira ntchito yofunika kwambiri m'dera la EV pazabwinozo.
Electrochemistry ya NiMH Battery
Batire ya NiMH imagwira ntchito pa mfundo yotengera kuyamwa, kutulutsa, ndi kunyamula kwa Hydrogen mkati mwa maelekitirodi awiri.
Elekitirodi yabwino:
Ni(OH)2+OH-=NiOOH+H2O+e-
Negative electrode:
M+H2O+e-=MHab+OH-
Zonse zomwe zimachitika:
Ni(OH)2+M=NiOOH+MH
Zochita izi zimatha kusinthidwa mukalipira, ndipo ma equation amayenda kuchokera kumanja kupita kumanzere.
Kugwiritsa ntchito kwa Battery ya NiMH
Mabatire a NiMH amagwiritsidwa ntchito kwambiri pazida zamagetsi, makamera a digito, magalimoto amagetsi, ndi zida zina.Kupatula apo, mabatire a NiMH ali ndi magwiridwe antchito abwino kwambiri otsika komanso ndi oyenera kutulutsa kwakanthawi kochepa, motero amasonkhanitsidwa mu mapaketi a batri a NiMH kuti akwaniritse zofunikira za zida zamagetsi, monga osindikiza, zida zamagetsi, zida zamagetsi, ndi magetsi. zidole, etc.
Makhalidwe ophatikizika a mabatire a NiMH, monga kuchuluka kwamphamvu kwamagetsi, mphamvu yayikulu komanso kusaipitsa, amawapangitsanso kukhala oyenera kugwiritsidwa ntchito ngati mabatire amagetsi, ndipo mafakitale ena a NiMH agwiritsa ntchito mabatire a NiMH a EVs, njinga zamoto zamagetsi ndi njinga zamagetsi. .Izi zawonjezedwanso kwa asitikali, ndikugwiritsa ntchito mphamvu zosunga zolumikizirana, ukadaulo wamlengalenga, maloboti, ndi masitima apamadzi.
Kugwiritsa Ntchito ndi Kukonza Mabatire a NiMH
Mabatire a NiMH ayenera kugwiritsidwa ntchito mosamala pakukonza.
Pewani kulipiritsa ndalama mukamagwiritsa ntchito.M'moyo wozungulira, kugwiritsa ntchito sikuyenera kuchulukitsidwa chifukwa kuchulukitsitsa kumatha kupangitsa kuti ma elekitirodi abwino komanso olakwika atukuke, zomwe zimapangitsa kuti zinthu zogwira ntchito zigwe ndikuwonongeka kwa diaphragm, netiweki ya conductive iwonongeke, komanso batri ohmic. polarization kukhala wamkulu.
Kusungidwa kwa mabatire a NiMH kuyenera kuchitidwa pambuyo pa kulipira kokwanira.Ngati mabatire asungidwa kwa nthawi yayitali popanda ndalama zokwanira, ntchito ya electrode hydrogen storage alloy idzakhala yofooka ndipo moyo wa batri udzafupikitsidwa.
Chifukwa chiyani Sankhani Weijiang ngati Professional NiMH Battery Manufacture?
Ku China, mabatire a NiMH apeza chitukuko chofulumira m'zaka makumi angapo zapitazi.Mu 2006, China idapanga mabatire a 1.3 biliyoni a NiMH, kupitilira Japan monga wopanga wamkulu padziko lonse lapansi.China ili ndi 70% ya nkhokwe zapadziko lapansi zomwe sizipezeka padziko lonse lapansi, zopangira zazikulu zamabatire a NiMH 'anode hydrogen storage alloy.Izi zitha kuthandiza kuchepetsa mtengo wopanga mabatire a NiMH ku China.
Cholinga chathu ndikupereka mphamvu zotetezeka, zodalirika komanso zotsika mtengo za NiMH zokongoletsedwa ndi zomwe mukufuna.Poyang'ana makonda, ma batire athu amtundu wa NiMH amatsimikizira kuti mabatire athu a NiMH amakwaniritsa zosowa zanu, mongamakonda A batire ya NiMH, batire yamtundu wa AA NiMH, batire yamtundu wa AAA NiMH, chizolowezi C NiMH batire, makonda a D NiMH batire, makonda a 9V NiMH batire, batire yamtundu wa F NiMH, custom Sub C NiMH Battery ndimwachizolowezi NiMH batire paketi.Timathandizana nanu kuti timvetse mozama za zosowa zanu ndi zovuta zanu, kenako ndikupanga mayankho aluso ogwirizana ndi zomwe mukufuna.
