▍Kutheni i-MCM?
● Ukuthathelwa ingqalelo kokufaneleka: I-MCM yilabhoratri yekhontrakthi evunyiweyo ye-CQC kunye nelebhu evunyiweyo yiCESI. Ingxelo yovavanyo ekhutshiweyo ingasetyenziswa ngokuthe ngqo kwi-CQC okanye isatifikethi se-CESI;
● Inkxaso yobuchwephesha: I-MCM inezixhobo zokuvavanya i-GB31241 eyaneleyo kwaye ixhotyiswe ngamagcisa aqeqeshiweyo angaphezu kwe-10 ukwenza uphando olunzulu ngovavanyo lweteknoloji, isiqinisekiso, uphicotho-zincwadi lwefektri kunye nezinye iinkqubo, ezinokubonelela ngeenkonzo ezichaneke ngakumbi nezilungiselelwe isiqinisekiso se-GB 31241 kwihlabathi jikelele. abathengi.
Kwimizi-mveliso yeemoto zamandla amatsha, iibhetri ze-lithium ze-ternary kunye neebhetri ze-lithium iron phosphate bezisoloko zijolisa kwingxoxo. Zombini zineengenelo kunye nezingeloncedo zazo. Ibhetri ye-lithium ye-ternary inobuninzi bamandla aphezulu, ukusebenza kakuhle kweqondo lokushisa eliphantsi, kunye noluhlu oluphezulu lokuhamba ngenqanawa, kodwa ixabiso liyabiza kwaye alizinzile. I-LFP itshiphu, izinzile, kwaye inomsebenzi olungileyo wobushushu obuphezulu. Izinto ezingeloncedo kukungaqhubi kakuhle kobushushu obuphantsi kunye nokuxinana kwamandla aphantsi. Kwinkqubo yophuhliso lweebhetri ezimbini, ngenxa yemigaqo-nkqubo eyahlukeneyo kunye neemfuno zophuhliso, iindidi ezimbini zidlala ngokuchaseneyo kunye naphantsi. Kodwa kungakhathaliseki ukuba ezi ntlobo zimbini zikhula njani, ukusebenza kokhuseleko yinto ephambili.
Iibhetri ze-lithium-ion zenziwa ikakhulu ngezinto ezingezizo ze-electrode, i-electrolyte kunye nezinto ezintle ze-electrode. Umsebenzi weekhemikhali we-graphite ye-electrode engalunganga isondele kwi-lithium yensimbi kwimeko ehlawulisiweyo. Ifilimu ye-SEI ebusweni iyancipha kwiqondo lokushisa eliphezulu, kwaye i-lithium ion efakwe kwi-graphite isabela nge-electro lyte kunye ne-binder polyvinylidene fluoride ukukhulula ubushushu obuninzi. Izisombululo ze-Alkyl carbonate eziphilayo zisetyenziswa ngokuqhelekileyo njenge-electrolytes, ezinokutsha. Izinto ze-electrode ezintle zidla ngokuba yi-oxide yensimbi yenguqu, enepropathi eyomeleleyo ye-oxi dizing kwimo ehlawuliswayo, kwaye ichithwa ngokulula ukukhulula i-oksijini kwiqondo lokushisa eliphezulu. I-oksijeni ekhutshiweyo ifumana i-oxidation reaction kunye ne-electrolyte, kwaye emva koko ikhupha inani elikhulu lobushushu.Ngoko ke, ukusuka kwindawo yokujonga izinto, iibhetri ze-lithium-ion zinomngcipheko onamandla, ngakumbi kwimeko yokusetyenziswa kakubi, imiba yokhuseleko ingaphezulu. abadumileyo. Ukuze ukulinganisa kunye nokuthelekisa ukusebenza kweebhetri ezimbini ze-lithium-ion ezahlukeneyo phantsi kweemeko eziphezulu zokushisa, senze olu vavanyo lulandelayo lokufudumeza.
