Isishwankathelo sophuhliso lweLithium ibhetri electrolyte,
Lithium ibhetri electrolyte,

▍Isiqinisekiso se-MIC saseVietnam

ISetyhula 42/2016/TT-BTTTT ichaze ukuba iibhetri ezifakwe kwiifowuni eziphathwayo, iitafile kunye neencwadana zokubhalela azivumelekanga ukuba zithunyelwe eVietnam ngaphandle kokuba ziphantsi kwe-DoC certifctaion ukususela ngo-Oct.1,2016. I-DoC iya kuphinda ifuneke ukuba ibonelele xa ifaka isicelo sokuVunywa koHlobo lweemveliso zokuphela konyaka (iimfonomfono eziphathwayo, iitafile kunye neencwadana).

I-MIC ikhuphe iSetyhula entsha ye-04/2018/TT-BTTT ngoMeyi, i-2018 echaza ukuba akukho ngxelo ye-IEC 62133:2012 ekhutshwe yilabhoratri evunyiweyo yaphesheya yamkelwa ngoJulayi 1, 2018. Uvavanyo lwendawo luyimfuneko ngelixa ufaka isicelo sesatifikethi se-ADoC.

▍PQIR

Urhulumente waseVietnam ukhuphe umyalelo omtsha onguNombolo 74/2018 / ND-CP ngoMeyi 15, 2018 ukuba uchaze ukuba iintlobo ezimbini zeemveliso ezingeniswe eVietnam zixhomekeke kwi-PQIR (Ukubhaliswa kokuHlolwa koMgangatho weMveliso) xa zithunyelwa eVietnam.

Ngokusekelwe kulo mthetho, i-Ofisi yoLwazi kunye noNxibelelwano (MIC) yaseVietnam ikhuphe uxwebhu olusemthethweni lwe-2305/BTTTT-CVT ngoJulayi 1, 2018, oluchaza ukuba iimveliso eziphantsi kolawulo lwayo (kubandakanywa neebhetri) kufuneka zifakwe kwi-PQIR xa zithunyelwa ngaphandle. ukuya eVietnam. I-SDoC iya kungeniswa ukuze igqibezele inkqubo yokukhutshwa kwempahla ekhoyo. Umhla osemthethweni wokungena ekusebenzeni kwalo mmiselo ngo-Agasti 10, 2018. I-PQIR isetyenziswa ekungeniseni enye eVietnam, oko kukuthi, rhoqo xa umthengisi engenisa iimpahla, uya kufaka isicelo se-PQIR (ukuhlolwa kwebhetshi) + SDoC.

Nangona kunjalo, kubarhwebi abangxamisekileyo ukuba bangenise iimpahla ngaphandle kwe-SDOC, i-VNTA iya kuqinisekisa okwethutyana i-PQIR kwaye iququzelele ukukhutshwa kwempahla. Kodwa abathumeli bangaphandle kufuneka bangenise i-SDoC kwi-VNTA ukuze igqibezele inkqubo yokukhutshwa kwempahla ngaphandle kwempahla ngaphakathi kwe-15 leentsuku zokusebenza emva kokukhutshwa kwempahla ephumayo. (I-VNTA ayisayi kuphinda ikhuphe i-ADOC yangaphambili esebenza kuphela kwi-Vietnam Local Manufacturers)

▍Kutheni i-MCM?

● Umxhasi woLwazi lwamva nje

● Umseki wegumbi lovavanyo lwebhetri yeQuacert

I-MCM ngoko iba yeyona arhente ikuphela kwayo yale lebhu e-Mainland China, eHong Kong, eMacau naseTaiwan.

● Inkonzo ye-Arhente yokuma enye

I-MCM, i-arhente efanelekileyo yokumisa enye, ibonelela ngovavanyo, isatifikethi kunye nenkonzo ye-arhente kubathengi.

Kwi-1800, i-physicist yaseNtaliyane u-A. Volta wakha imfumba ye-voltaic, eyavula ukuqala kweebhetri eziphathekayo kwaye yachaza okokuqala ukubaluleka kwe-electrolyte kwizixhobo zokugcina amandla e-electrochemical. I-electrolyte inokubonwa njenge-electronic insulating kunye ne-ion-conducting layer ngendlela yolwelo okanye eqinile, efakwe phakathi kwee-electrodes ezimbi kunye ezintle. Okwangoku, eyona electrolyte iphucukileyo yenziwa ngokunyibilikisa ityuwa yelithium eqinileyo (umz. LiPF6) kwisinyibilikisi esingenamanzi se-organic carbonate (umz. EC kunye neDMC). Ngokwefomu yeseli ngokubanzi kunye noyilo, i-electrolyte ithatha i-8% ukuya kwi-15% yobunzima beeseli. Ngaphezu koko, ukutsha kwayo kunye nomgangatho wobushushu osebenzayo obuphakathi kwe-10°C ukuya kuma-60°C ithintela kakhulu ukuphuculwa okungaphaya kwamandla ebhetri nokhuseleko. Ngoko ke, ukuqulunqwa kwezinto ezintsha ze-electrolyte zithathwa njengeyona nto iphambili ekuphuhliseni isizukulwana esilandelayo seebhetri ezintsha.Abaphandi basebenza ukuphuhlisa iinkqubo ezahlukeneyo ze-electrolyte. Ngokomzekelo, ukusetyenziswa kwe-solvents ene-fluorinated enokuthi iphumelele i-lithium ye-cycling yensimbi esebenzayo, i-organic ororganic solid electrolytes enenzuzo kwishishini lezithuthi kunye "neebhetri zombuso oqinileyo" (SSB). Esona sizathu sikukuba ukuba i-electrolyte eqinileyo ithatha indawo ye-electrolyte yolwelo yokuqala kunye ne-diaphragm, ukhuseleko, ukuxinana kwamandla kunye nobomi bebhetri bunokuphuculwa kakhulu. Okulandelayo, sishwankathela kakhulu inkqubela yophando yee-electrolytes eziqinileyo ezinezixhobo ezahlukeneyo.I-electrolyte eqinileyo esetyenzisiweyo isetyenzisiwe kurhwebo lwezixhobo zokugcina amandla e-electrochemical, ezifana neebhetri ezihlaziyiweyo ezinobushushu obuphezulu i-Na-S, i-Na-NiCl2 ibhetri kunye ne-primary Li-I2 iibhetri. . Emuva ngo-2019, u-Hitachi Zosen (eJapan) ubonise ibhetri ye-pouch-state-slid-state ye-140 mAh ukuba isetyenziswe emajukujukwini kwaye ivavanywe kwiSikhululo seNdawo samazwe ngamazwe (ISS). Le bhetri yenziwe nge-sulfide electrolyte kunye nezinye iinxalenye zebhetri ezingachazwanga, ezikwaziyo ukusebenza phakathi kwe -40°C kunye ne-100°C. Ngo-2021 inkampani ivelisa umthamo ophezulu webhetri eyomeleleyo ye-1,000 mAh. U-Hitachi Zosen ubona imfuneko yeebhetri eziqinileyo kwiindawo ezinzima ezifana nendawo kunye nezixhobo zoshishino ezisebenza kwindawo eqhelekileyo. Inkampani iceba ukuphinda kabini umthamo webhetri ngo-2025. Kodwa okwangoku, akukho mveliso yebhetri engabonakaliyo yonke into enokuthi isetyenziswe kwizithuthi zombane.
