Amazinga angu-5 agunyazwe kakhulu okuphepha kwebhethri (amazinga asezingeni lomhlaba)

Ibhethri ye-lithium-ionizinhlelo ziyizinhlelo eziyinkimbinkimbi ze-electrochemical kanye nemishini, futhi ukuphepha kwephakethe lebhethri kubalulekile ezimotweni zikagesi. "Izimfuneko Zokuphepha Kwezimoto zikagesi" zaseChina, ezisho ngokusobala ukuthi isistimu yebhethri iyadingeka ukuthi ingabangi umlilo noma iqhume phakathi nemizuzu engu-5 ngemva kokushisa okushisayo kwe-monomer yebhethri, okushiya isikhathi sokuphunyuka esiphephile kubagibeli.

(1) Ukuphepha okushisayo kwamabhethri kagesi

Amazinga okushisa aphansi angaholela ekusebenzeni kabi kwebhethri kanye nokulimala okungenzeka, kodwa ngokuvamile awabeki ubungozi bezokuphepha. Kodwa-ke, ukushaja ngokweqile (i-voltage ephezulu kakhulu) kungaholela ekuboleni kwe-cathode kanye ne-electrolyte oxidation. Ukuchichima ngokweqile (i-voltage ephansi kakhulu) kungaholela ekuboleni kwesixhumi esibonakalayo se-electrolyte esiqinile (SEI) ku-anode futhi kungase kuholele ekukhishweni kwe-oxidation ye-foil yethusi, kuqhubeke kulimaze ibhethri.

(2) I-IEC 62133 ejwayelekile

I-IEC 62133 (Izinga lokuhlola ukuphepha lamabhethri namaseli e-lithium-ion), imfuneko yokuphepha yokuhlola amabhethri esibili namaseli aqukethe i-alkaline noma ama-electrolyte angenayo i-asidi. Isetshenziselwa ukuhlola amabhethri asetshenziswa kuma-elekthronikhi aphathwayo nezinye izinhlelo zokusebenza, ukubhekana nezingozi zamakhemikhali nezikagesi kanye nezinkinga zemishini ezifana nokudlidliza nokushaqeka okungasongela abathengi nendawo.

(3)UN/DOT 38.3

I-UN/DOT 38.3 (T1 - T8 test kanye ne-UN ST/SG/AC.10/11/Rev. 5), emboza wonke amaphakethe ebhethri, amaseli ensimbi e-lithium namabhethri okuhlola ukuphepha kwezokuthutha. Izinga lokuhlola liqukethe izivivinyo eziyisishiyagalombili (T1 - T8) ezigxile ezingozini ezithile zokuthutha.

(4) I-IEC 62619

I-IEC 62619 (Izinga Lokuphepha Lamabhethri eSecondary Lithium namaphakethe Ebhethri), izinga licacisa izidingo zokuphepha zamabhethri akugesi nezinye izinhlelo zokusebenza zezimboni. Izidingo zokuhlola zisebenza kuzo zombili izinhlelo zokusebenza ezimile nezinamandla. Izinhlelo zokusebenza ezimile zifaka ezokuxhumana, amandla kagesi angaphazamiseki (i-UPS), amasistimu okugcina amandla kagesi, ukushintsha kwezinsiza, amandla aphuthumayo nezinye izinhlelo ezifanayo. Izinhlelo zokusebenza ezinamandla zihlanganisa ama-forklift, amakalishi egalufu, izimoto eziqondiswayo ezizenzakalelayo (ama-AGV), imizila yezitimela, nemikhumbi (ngaphandle kwezimoto ezihamba emgwaqeni).

(5)UL 2580x

I-UL 2580x (UL Safety Standard for Electric Vehicle Batteries), ehlanganisa ukuhlola okumbalwa.

Isekhethi Yamanje Efushane Yebhethri Ephakeme: Lokhu kuhlola kwenziwa ngesampula eshajwe ngokugcwele. Isampula ifinyezwa kusetshenziswa ukuphikiswa kwesekethe okuphelele okungu-≤ 20 mΩ. I-Spark ignition ithola ukuba khona kokugxiliswa kwegesi okuvuthayo kusampula futhi azikho izimpawu zokuqhuma noma umlilo.

I-Battery Crush: Qalisa ngesampula eshajwe ngokugcwele futhi ulingise imiphumela yokuphahlazeka kwemoto kubuqotho be-EESA. Njengokuhlolwa kwesekethe emfushane, ukuthungela kwenhlansi kuthola ukuba khona kokugxilisana okuvuthayo kwegesi kusampula futhi akukho nkomba yokuqhuma noma umlilo. Awekho amagesi anobuthi akhishwayo.

Ukuminyanisa Iseli Yebhethri (Kuqondile): Qalisa kusampula eshajwe ngokugcwele. Amandla asetshenziswa ekuhlolweni kokuminyanisa kufanele akhawulelwe izikhathi eziyi-1000 zesisindo seseli. Ukutholwa kokushisa kwenhlansi kuyafana nalokho okusetshenziswa ekuhlolweni kokuminyanisa.

(6) Izidingo zokuphepha zezimoto zikagesi (GB 18384-2020)

Izidingo Zokuphepha Ezimotweni zikagesi" izinga likazwelonke le-People's Republic of China elasetshenziswa ngoJanuwari 1, 2021, elibeka izidingo zokuphepha nezindlela zokuhlola zezimoto zikagesi.

Isikhathi sokuthumela: Jan-30-2023
