Ukuhlolwa kokushisisa okweqile kwe-Ternary li-cell kanye ne-LFP cell,
futhi inokusebenza okuhle kwezinga lokushisa eliphezulu. Ububi ukusebenza kabi kwezinga lokushisa eliphansi kanye nokuminyana kwamandla aphansi. Enqubweni yokuthuthukiswa kwamabhethri amabili, kanye nebanga eliphezulu lokuhamba ngomkhumbi, futhi ibola kalula ukuze ikhulule umoya-mpilo ezingeni lokushisa eliphezulu. I-oxygen ekhishiwe ibhekana nokusabela kwe-oxidation nge-electrolyte, futhi ama-ion e-lithium ashumekwe ku-graphite asabela nge-electrolyte kanye ne-binder polyvinylidene fluoride ukuze akhulule ukushisa okukhulu. I-Alkyl carbonate organic solutions ivame ukusetshenziswa njengogesi, bese ekhulula inani elikhulu lokushisa. Ngakho-ke, kodwa intengo iyabiza futhi ayizinzile. I-LFP ishibhile, ngenxa yezinqubomgomo nezidingo zentuthuko ezahlukene, i-electrolyte kanye nezinto ezibonakalayo ze-electrode. Umsebenzi wamakhemikhali we-graphite yezinto ze-electrode negative useduze nalowo we-metallic lithium esimweni esikhokhisiwe. Ifilimu ye-SEI ebusweni de, ikakhulukazi endabeni yokuhlukunyezwa, ngokombono wezinto zokwakha, ukusebenza okuhle kwezinga lokushisa eliphansi, Embonini entsha yezimoto zamandla, amabhethri e-lithium-ion anengozi eqinile, izindaba zokuphepha zigqame kakhulu. Ukuze ulingise futhi uqhathanise ukusebenza kwamabhethri e-lithium-ion amabili ahlukene ngaphansi kwezimo zokushisa eziphezulu, ezinzile, Amabhethri e-lithium e-ternary kanye namabhethri e-lithium iron phosphate bekulokhu kugxilwe kwengxoxo. Kokubili kunezinzuzo kanye nokubi. Ibhethri ye-lithium ye-ternary ine-densi yamandla aphezulu, ukusebenza kokuphepha kuyisici esibalulekile. Amabhethri e-lithium-ion ikakhulukazi akhiwe ngezinto ezingezinhle ze-electrode, izinhlobo ezimbili zidlala ngokumelene phezulu naphansi. Kodwa kungakhathaliseki ukuthi lezi zinhlobo ezimbili zikhula kanjani, senze ukuhlolwa kokushisa okunezinyathelo ezilandelayo., ezingavutha. I-electrode material eqondile ngokuvamile i-transition metal oxide, enendawo eqinile ye-oxi dizing esimweni esikhokhisiwe,

▍Siyini isitifiketi se-TISI?

I-TISI ifushane nge-Thai Industrial Standards Institute, exhumene noMnyango Wezimboni waseThailand. I-TISI inomthwalo wemfanelo wokwenza amazinga asekhaya kanye nokubamba iqhaza ekwakhiweni kwamazinga omhlaba kanye nokwengamela imikhiqizo kanye nenqubo yokuhlola efanelekayo ukuze kuqinisekiswe ukuthotshelwa okujwayelekile nokuqashelwa. I-TISI yinhlangano egunyazwe uhulumeni elawulayo yesitifiketi esiyimpoqo e-Thailand. Futhi inomthwalo wemfanelo wokwakhiwa nokuphathwa kwamazinga, ukugunyazwa kwelebhu, ukuqeqeshwa kwabasebenzi nokubhaliswa kwemikhiqizo. Kuyaphawulwa ukuthi awukho umgwamanda wokunikeza izitifiketi oyimpoqo ongekho ngaphansi kukahulumeni e-Thailand.

Kunesitifiketi sokuzithandela nesiyimpoqo eThailand. Amalogo e-TISI (bona uMdwebo 1 no-2) avunyelwe ukusetshenziswa lapho imikhiqizo ihlangabezana nezindinganiso. Emikhiqizweni engakamiswa, i-TISI iphinde isebenzise ukubhaliswa komkhiqizo njengendlela yesikhashana yokuqinisekisa.

▍ Ububanzi Bokugunyazwa Okuphoqelekile

Isitifiketi esiyimpoqo sihlanganisa izigaba eziyi-107, izinkambu eziyi-10, okuhlanganisa: izinto zikagesi, izesekeli, okokwelashwa, izinto zokwakha, izimpahla zabathengi, izimoto, amapayipi e-PVC, iziqukathi zegesi ye-LPG kanye nemikhiqizo yezolimo. Imikhiqizo engaphezulu kwalo mkhakha iwela ngaphakathi kwesikhala sokuzithandela sokuthola izitifiketi. Ibhethri iwumkhiqizo wesitifiketi oyimpoqo esitifiketini se-TISI.

Izinga elisetshenzisiwe:I-TIS 2217-2548 (2005)

Amabhethri asetshenzisiwe:Amaseli esibili namabhethri (aqukethe i-alkaline noma amanye ama-electrolyte angewona ama-asidi - izimfuneko zokuphepha zamaseli esibili avaliwe, namabhethri enziwe ngawo, ukuze asetshenziswe ezinhlelweni eziphathwayo)

Igunya lokukhishwa kwelayisensi:I-Thai Industrial Standards Institute

▍Kungani i-MCM?

● I-MCM ibambisana nezinhlangano zokuhlolwa kwemboni, ilabhorethri kanye ne-TISI ngokuqondile, ekwazi ukunikeza isisombululo esingcono kakhulu sokunikeza izitifiketi kumakhasimende.

● I-MCM inesipiliyoni seminyaka engu-10 esichichimayo embonini yebhethri, ekwazi ukuhlinzeka ngosekelo lobuchwepheshe oluchwepheshile.

● I-MCM inikeza isevisi yenqwaba yesitobhi esisodwa ukuze isize amakhasimende angene ezimakethe eziningi (hhayi kuphela i-Thailand efakiwe) ngempumelelo ngenqubo elula.

Embonini entsha yezimoto zamandla, Amabhethri e-lithium e-ternary kanye namabhethri e-lithium iron phosphate bekulokhu kugxilwe kwengxoxo. Kokubili kunezinzuzo kanye nokubi. Ibhethri ye-lithium ye-ternary ine-densi yamandla aphezuluwena,ukusebenza okuhle kwezinga lokushisa eliphansi, kanye nebanga eliphezulu lokuhamba ngomkhumbi, kodwa intengo iyabiza futhi ayizinzile. I-LFP ishibhile, ezinzile, futhi inokusebenza okuhle kwezinga lokushisa eliphezulu. Ububi ukusebenza kabi kwezinga lokushisa eliphansi kanye nokuminyana kwamandla aphansi.
Enqubweni yokuthuthukiswa kwamabhethri amabili,ngenxa yezinqubomgomo nezidingo zentuthuko ezahlukene, izinhlobo ezimbili zidlala ngokumelene phezulu naphansi. Kodwa kungakhathaliseki ukuthi lezi zinhlobo ezimbili zikhula kanjani, ukusebenza kokuphepha kuyisici esibalulekile. Amabhethri e-lithium-ion ikakhulukazi akhiwe ngezinto ezingezinhle ze-electrode, i-electrolyte kanye nezinto ezibonakalayo ze-electrode. Umsebenzi wamakhemikhali we-graphite yezinto ze-electrode negative useduze nalowo we-metallic lithium esimweni esikhokhisiwe. Ifilimu ye-SEI ebusweni deihlanganisa emazingeni okushisa aphezulu, futhi ama-ion e-lithium ashumekwe ku-graphite asabela nge-electrolyte kanye ne-binder polyvinylidene fluoride ukuze akhulule ukushisa okukhulu. Izixazululo ze-Alkyl carbonate eziphilayo zivame ukusetshenziswa njenge
ama-electrolyte,ezingavutha. I-electrode material eqondile ngokuvamile i-transition metal oxide, enendawo eqinile ye-oxi dizing esimweni esikhokhisiwe, futhi ibola kalula ukuze ikhulule umoya-mpilo ezingeni lokushisa eliphezulu. I-oxygen ekhishiwe ibhekana nokusabela kwe-oxidation nge-electrolyte, bese ikhulula inani elikhulu lokushisa.
Ngakho-ke,ngokombono wezinto zokwakha, amabhethri e-lithium-ion anengozi eqinile, ikakhulukazi endabeni yokuhlukunyezwa, izindaba zokuphepha zigqame kakhulu. Ukuze ulingise futhi uqhathanise ukusebenza kwamabhethri e-lithium-ion amabili ahlukene ngaphansi kwezimo zokushisa eziphezulu, senze ukuhlolwa kokushisa okunezinyathelo ezilandelayo.
