Uvavanyo lokufudumeza olunyathelweyo lwe-Ternary li-cell kunye neseli ye-LFP,
kwaye inomsebenzi olungileyo wobushushu obuphezulu. Izinto ezingeloncedo kukungaqhubi kakuhle kobushushu obuphantsi kunye nokuxinana kwamandla aphantsi. Kwinkqubo yophuhliso lweebhetri ezimbini, kunye noluhlu oluphezulu lokuhamba ngenqanawa, kwaye ibola ngokulula ukuze ikhulule ioksijini kwiqondo lobushushu eliphezulu. Ioksijini ekhutshiweyo ifumana i-oxidation reaction kunye ne-electrolyte, kunye ne-lithium ion efakwe kwi-graphite isabela nge-electrolyte kunye ne-binder polyvinylidene fluoride ukukhulula ubushushu obuninzi. Izisombululo ze-Alkyl carbonate eziphilayo zisetyenziswa ngokuqhelekileyo njengombane, kwaye emva koko ikhuphe inani elikhulu lobushushu. Ngoko ke, kodwa ixabiso liyabiza kwaye alizinzanga. I-LFP itshiphu, ngenxa yemigaqo-nkqubo eyahlukeneyo kunye neemfuno zophuhliso, i-electrolyte kunye nezinto ezintle ze-electrode. Umsebenzi weekhemikhali we-graphite ye-electrode engalunganga isondele kwi-lithium yensimbi kwimeko ehlawulisiweyo. Ifilimu ye-SEI kumphezulu de, ngakumbi kwimeko yokuxhatshazwa, ukusuka kwindawo yokujonga izinto, ukusebenza kakuhle kobushushu obuphantsi, Kwishishini elitsha leemoto zamandla, iibhetri ze-lithium-ion zinomngcipheko onamandla, imiba yokhuseleko ibonakala ngakumbi. Ukuze ulinganise kwaye uthelekise ukusebenza kweebhetri ezimbini ze-lithium-ion ezahlukeneyo phantsi kweemeko eziphezulu zokushisa, ezinzile, iibhetri ze-lithium ze-lithium kunye neebhetri ze-lithium iron phosphate bezisoloko zigxininise kwingxoxo. Zombini zineengenelo kunye nezingeloncedo zazo. Ibhetri ye-lithium ye-ternary ine-densi yamandla aphezulu, ukusebenza kokhuseleko yeyona nto iphambili. Iibhetri ze-lithium-ion zenziwa ikakhulu ngezinto ezimbi ze-electrode, iindidi ezimbini zidlala ngokuchaseneyo phezulu naphantsi. Kodwa kungakhathaliseki ukuba ezi ntlobo zimbini zikhula njani, senze olu vavanyo lulandelayo lokufudumeza., ezinokutsha. Izinto eziphathekayo ze-electrode zidla ngokuba yi-oxide yensimbi yenguqu, enepropathi eyomeleleyo ye-oxi dizing kwimo ehlawuliswayo,

▍Yintoni isiqinisekiso se-TISI?

I-TISI imfutshane ye-Thai Industrial Standards Institute, enxulumana neSebe leShishini laseThailand. I-TISI inoxanduva lokuqulunqa imigangatho yasekhaya kunye nokuthatha inxaxheba ekuqulunqweni kwemigangatho yamazwe ngamazwe kunye nokubeka iliso kwiimveliso kunye nenkqubo yovavanyo olufanelekileyo ukuqinisekisa ukuthotyelwa komgangatho kunye nokuqatshelwa. I-TISI ngumbutho ogunyazisiweyo ngurhulumente olawula isiqinisekiso esisisinyanzelo eThailand. Ikwanoxanduva lokuqulunqa nokulawula imigangatho, ukuvunywa kwelebhu, uqeqesho lwabasebenzi kunye nokubhaliswa kwemveliso. Kuqatshelwe ukuba akukho ziko lezatifikethi ezisisinyanzelo ezingekho phantsi kukarhulumente eThailand.

Kukho isiqinisekiso sokuzithandela nesinyanzelekileyo eThailand. Iimpawu ze-TISI (jonga iMifanekiso 1 kunye ne-2) zivumelekile ukuba zisetyenziswe xa iimveliso zihlangabezana nemigangatho. Kwiimveliso ezingekalungiswa, i-TISI iphinda isebenzise ukubhaliswa kwemveliso njengendlela yesikhashana yokuqinisekisa.

▍UMda weSiqinisekiso esiSinyanzelo

Isiqinisekiso esinyanzelekileyo sibandakanya iindidi ze-107, iindawo ezili-10, ezibandakanya: izixhobo zombane, izixhobo, izixhobo zonyango, izinto zokwakha, iimpahla zabathengi, izithuthi, imibhobho ye-PVC, izitya zegesi ze-LPG kunye neemveliso zezolimo. Iimveliso ezingaphaya kwalo mda ziwela ngaphakathi komda wezatifikethi ngokuzithandela. Ibhetri yimveliso enyanzelekileyo yokuqinisekiswa kwisatifikethi se-TISI.

Umgangatho osetyenziswayo:TIS 2217-2548 (2005)

Iibhetri ezifakiweyo:Iiseli eziziiSekondari kunye neebhetri (eziqulethe ialkaline okanye ezinye i-electrolyte ezingekho-asidi-iimfuno zokhuseleko kwiiseli eziphathwayo ezitywiniweyo, kunye neebhetri ezenziwe kuzo, ukuze zisetyenziswe kwizicelo eziphathekayo)

Igunya lokukhutshwa kwelayisensi:Iziko leMigangatho yoShishino lwaseThai

▍Kutheni i-MCM?

● I-MCM isebenzisana nemibutho yophicotho-zincwadi lwasefektri, ilabhoratri kunye ne-TISI ngokuthe ngqo, ekwaziyo ukubonelela ngesisombululo sesatifikethi esingcono kubaxhasi.

● I-MCM ineminyaka eyi-10 yamava amaninzi kushishino lwebhetri, ekwaziyo ukubonelela ngenkxaso yobuchwephesha.

● I-MCM inikezela ngenkonzo ye-stop-stop bundle ukunceda abathengi bangene kwiimarike ezininzi (kungekhona kuphela iThailand equkiweyo) ngempumelelo ngenkqubo elula.

Kwishishini elitsha leemoto zamandla, iibhetri ze-lithium ze-lithium kunye neebhetri ze-lithium iron phosphate bezisoloko zigxininise kwingxoxo. Zombini zineengenelo kunye nezingeloncedo zazo. Ibhetri ye-lithium ye-ternary ine-densi yamandla aphezuluwena,ukusebenza kakuhle kobushushu obuphantsi, kunye noluhlu oluphezulu lokuhamba ngenqanawa, kodwa ixabiso liyabiza kwaye alizinzanga. I-LFP itshiphu, ezinzile, 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 phezulu naphantsi. Kodwa kungakhathaliseki ukuba ezi ntlobo zimbini zikhula njani, ukusebenza kokhuseleko yeyona nto iphambili. Iibhetri ze-lithium-ion zenziwa ikakhulu ngezinto ezimbi 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 kumphezulu deiqulunqa kumaqondo okushisa aphezulu, kwaye i-ion ze-lithium efakwe kwi-graphite isabela nge-electro lyte kunye ne-binder polyvinylidene fluoride ukukhulula ubushushu obuninzi. Alkyl carbonate izisombululo eziphilayo ziqhele ukusetyenziswa njenge
i-electrolytes,ezinokutsha. Izinto eziphathekayo ze-electrode zidla ngokuba yi-oxide yensimbi yenguqu, enepropathi eyomeleleyo ye-oxi dizing kwimo ehlawuliswayo, kwaye ibola ngokulula ukuze ikhulule ioksijini kwiqondo lobushushu eliphezulu. Ioksijini ekhutshiweyo ifumana i-oxidation reaction kunye ne-electrolyte, kwaye emva koko ikhuphe inani elikhulu lobushushu.
Ngoko ke,ukusuka kwindawo yokujonga izinto, iibhetri ze-lithium-ion zinomngcipheko onamandla, ngakumbi kwimeko yokuxhatshazwa, imiba yokhuseleko ibonakala ngakumbi. Ukuze ulinganise kwaye uthelekise ukusebenza kweebhetri ezimbini ze-lithium-ion ezahlukeneyo phantsi kweemeko eziphezulu zokushisa, senze olu vavanyo lulandelayo lokufudumeza.
