Saddexda baahiyood ee waaweyn ee batteriga kaydinta tamarta, badbaadada ayaa ah tan ugu muhiimsan
Kaydinta tamarta korantada waxaa loo tixgeliyaa inay tahay qaabka ugu muhiimsan ee kaydinta tamarta ee nidaamka tamarta mustaqbalka, batteriga iyo PCS waa qiimaha ugu sarreeya iyo caqabadaha silsiladda warshadaha, baahida asaasiga ah waxay ku jirtaa badbaado sare, nolol dheer iyo qiimo jaban. Waxaa ka mid ah, badbaadada ayaa fure u ah. Qaar ka mid ah khubarada warshadaha ayaa sheegay, hadda warshadda tamarta kaydinta tamarta korantada ayaa si degdeg ah u horumarinaysa, laakiin arrinta badbaadadu waa cidhiidhiga horumarinta baaxadda weyn, warshadda tamarta kaydinta tamarta ee Beijing iyo mashruuca kaydinta tamarta ee Tesla Australia ee qaraxa sidoo kale loogu talagalay warshadaha kaydinta tamarta ayaa ka dhawaajiyay.
Si taas loo gaaro, Fikradaha Hagaha ee Dardargelinta Horumarinta Kaydinta Tamarta Cusub waxay soo bandhigaysaa aasaaska heerarka tignoolajiyada badbaadada iyo nidaamka maaraynta, xoojinta maaraynta badbaadada dabka, si adag u hoggaansama khadka hoose ee badbaadada sida mabda'a aasaasiga ah; badbaadada sare, qiimo jaban, kalsoonida sare, nolosha dheer iyo dhinacyada kale ee horumarka dheer; xoojinta badbaadada cilmi-baarista tignoolajiyada kaydinta tamarta korantada iyo wixii la mid ah. Komishanka Qaranka ee Horumarinta iyo Dib-u-habaynta, Guddiga Tamarta Qaranka si uu u abaabulo diyaarinta "Tallaabooyinka Ku-meel-gaadhka ah ee Maareynta Badbaadada ee Saldhigyada Kaydka Tamarta Korantada (Qabyada)", ayaa sidoo kale 24-kii Agoosto bulshada u diray wadatashi dadweyne, si loo xoojiyo maamulka. badbaadada kaydinta tamarta.
Badbaadada sare, nolol dheer, qiimaha baytariyada nikkel-biraha
Xogta Ururka Warshadaha Battery ee Shiinaha ayaa muujinaya in nikkel-birta hydride korantada amniga sare, nolosha wareegga dheer, electrode ay togan oo ka sameysan qaybaha nikkel, walxaha firfircoon ee korantada taban waxaa taageera daawaha kaydinta hydrogen, waxay iska leedahay walxo xasiloon, korantada biyaha ayaa wanaagsan Guryaha ololka, ma qarxi doonaan mana gubi doonaan shilalka, cufnaanta tamarta monomer ee baytarigu ilaa 140wh/kg; wareegga nolosha ee ilaa 3,000, dallacaadda gacmeed iyo bixinta wareegga gobolka ilaa 10,000 jeer ama ka badan; waxaa loo isticmaali karaa in ka badan 10,000 jeer; waxaa la isticmaali karaa in ka badan 10,000 jeer. In ka badan 10,000 jeer; waxay ilaalin kartaa heerka sare ee dallacaadda iyo ku shubista gudaha -40°C ~ 60°C deegaanka. Gawaarida Toyota HEV ee caalamiga ah ayaa gaadhay in ka badan 18 milyan, waxaana si balaadhan loogu qalabaysan yahay baytariyada nikkel-metal hydride, ma jiraan hal kiis oo shilalka gubanaya batteriga, badbaadada sare ee baytariga ayaa si buuxda loo xaqiijiyay.
Waxaa intaa dheer, ku dallaca batteriga iyo soo dayntu waa beddelka tamarta kiimikada iyo tamarta korontada, heerkulku wuxuu saameyn weyn ku leeyahay falcelinta kiimikada. Saldhigyada tamarta kaydinta tamarta inta badan waa bannaanka, badi noocyada baytariyada waxaa saameeya deegaanka iyo heerkulka, xaddidaya goobta xarumaha tamarta iyo daciifinta doorka kaydinta tamarta. baytariyada hydride nickel-birta ee heerkulka aadka u hooseeya iyo heerkulka sare lacag aad u fiican iyo hufnaanta dheecaanka, si ay goobta xarunta tamarta kaydinta badan dabacsanaan, ku haboon, waxqabadka guud ka wanaagsan, kaas oo noqday ka qaybgalka tartanka ee waddooyinka kala duwan ee batteriga " dhibcood lagu daray".
Dhab ahaantii, baytariyada nikkel-metal hydride ee codsiga kaydinta tamarta ee suuqa ayaa ahaa horudhac. 2020, nikkel-birta birta hydride tamarta kaydinta tamarta shirkadda Nilar by Baanka Maalgelinta Yurub 47 milyan oo Yuuro maalgashi. Waxaa la fahamsan yahay in Nilar ay diiradda saarayso isdhexgalka koronto la cusboonaysiin karo iyo kaydinta, awoodda heeganka ah iyo codsiyada ku dallaca baabuurta korontada, maalgashigu waa in kor loogu qaado shirkadda lagu dhex dari doono batteriga guryaha, ganacsiga iyo warshadaha iyo grid-cabirka ama nidaamyada suuqa kaabayaasha. . Sida laga soo xigtay Frontiers in Polymer Science, kooxda Professor Yi Cui ee Jaamacadda Stanford waxay soo saareen baytari nikkel-metal hydride (Ni-MH) oo loogu talagalay codsiyada tamarta dib loo cusboonaysiin karo iyo kuwa kaydinta, oo leh faa'iidooyinka nolosha adeegga aadka u dheer, ma jirto khatar Dabka ama kuleylka kuleylka, looma baahna dayactir joogto ah, dabeecad heerkul hoose oo wanaagsan, iyo qiimo jaban. Kooxda Cui waxa ay dhisi doonaan unug tijaabo ah oo awood kaydin ah oo dhan 2 megawatts sanadka 2021, waxa ayna qorshaynayaan in ay awoodooda ku balaadhiyaan 20 jeer lacagtaas marka la gaadho 2022
