Chizvarwa chitsva chesimba rekugadzirisa: 18650-70C sodium-ion bhatiri inodarika yechinyakare LiFePO4 bhatiri mukuita
Pamusangano weInternational Sustainable Energy Conference wakaitwa nhasi, bhatiri resodium-ion inonzi 18650-70C yakakwezva kutarisisa kwakapararira kubva kune vatori vechikamu. Iyo bhatiri inodarika iripo lithium iron phosphate (LiFePO4) bhatiri tekinoroji mune akawanda makiyi ekuita paramita uye inoonekwa seyambiro huru mumunda wesimba rinodzokororwa.
Kuita kwemabhatiri e-sodium-ion kunonyanya kukosha pasi pemamiriro ekushisa kwakanyanya. Tembiricha yaro yekubuda inogona kusvika minus 40 degrees Celsius, iyo inonyatsokodzera kunzvimbo dzinotonhora kupfuura minus 30 degrees Celsius yeLiFePO4 mabhatiri. Chinotonyanya kushamisa ndechekuti chiyero chekuchaja (3C) yebhatiri resodium-ion iyi yakapetwa katatu pane yebhatiri reLiFePO4 (1C), uye chiyero chekubuda (35C) chinopeta makumi matatu neshanu pane chekupedzisira (1C). Pasi peyakanyanya-mutoro pulse discharge mamiriro, iyo yakanyanya pulse discharge rate (70C) ingangoita 70 nguva yeLiFePO4 bhatiri (1C), inoratidza hukuru hwekuita.
Pamusoro pezvo, mabhatiri e-sodium-ion anogona kuburitswa zvizere ku0V pasina kukuvadza hupenyu hwebhatiri, izvo zvine kukosha kukuru kwekuwedzera hupenyu hwebhatiri. Mukutaura kwezvinhu zvakachengetwa, mabhatiri e-sodium-ion anoshandisa zvakawanda uye zvisingabvumirwi zviwanikwa, izvo zvinoreva kuti pasi rose, mabhatiri e-sodium-ion achave akachipa zvakanyanya maererano nekupa uye mutengo kupfuura mabhatiri eLiFePO4, ane zvishoma zviwanikwa zvelithium. Advantage.
Mukuona kwekuvandudzwa kwehutano hwekuchengetedza, bhatiri iyi inonzi "yakachengeteka", uye kunyange zvazvo mabhatiri eLiFePO4 ave achionekwa zvakanyanya semhando yakachengeteka yebhatiri, kana ichienzaniswa nemabhatiri matsva e-sodium-ion, iyo yekupedzisira iri pachena yakachengeteka.
Uku budiriro yetekinoroji inopa mhinduro nyowani dzemagetsi kumotokari dzemagetsi, nharembozha, uye yakakura-yakakura masisitimu ekuchengetedza simba, uye inotarisirwa kukonzera shanduko huru mumusika wepasi rose wekuchengetera simba.
Sezvo shanduko yesimba iri kuramba ichidzika, mabhindauko ehunyanzvi hwemabhatiri matsva akavhura musuwo weramangwana rakanaka, rakasvibira, uye rakasimba.
