Ubuchwepheshe obusha bebhethri - ibhethri ye-Sodium-ion,
ibhethri ye-sodium-ion,

▍Iyini i-KC?

Kusukela 25^thAug., 2008，Korea Ministry of Knowledge Economy (MKE) yamemezela ukuthi I-National Standard Committee izophatha uphawu olusha lwesitifiketi oluhlanganisiwe lukazwelonke - oluqanjwe uphawu lwe-KC oluthatha indawo yesitifiketi sase-Korea phakathi nesikhathi esiphakathi kuka-Jul. 2009 no-Dec. 2010. Isitifiketi sokuphepha se-Electrical Appliances isikimu (Isitifiketi se-KC) siwuhlelo lokuqinisekisa ukuphepha oluyisibopho kanye nokuzilawula ngokwalo ngokoMthetho Wokulawula Ukuphepha Kwezisetshenziswa zikagesi, isikimu esiqinisekisa ukuphepha kokukhiqizwa nokudayiswa.

Umehluko phakathi kwesitifiketi esiyisibopho nokuzilawula(ngokuzithandela)isiqinisekiso sokuphepha:

Ukuze kuphathwe ngokuphephile izinto zikagesi, isitifiketi se-KC sihlukaniswe izitifiketi zokuphepha eziphoqelekile nezizilawulayo (ngokuzithandela) njengokuhlukaniswa kwengozi yomkhiqizo. imiphumela eyingozi engathi sína noma isithiyo esinjengomlilo, ukushaqeka kukagesi. Ngenkathi izifundo zesitifiketi sokuphepha esizilawulayo (sokuzithandela) sisetshenziswa ezintweni zikagesi lapho izakhiwo nezindlela zokuzisebenzisa zingeke zibangele imiphumela eyingozi enkulu noma isithiyo esinjengomlilo, ukushaqeka kukagesi. Futhi ingozi nesithiyo kungavinjelwa ngokuhlola izinto zikagesi.

▍Ubani ongafaka isicelo sesitifiketi se-KC:

Bonke abantu abasemthethweni noma abantu ngabanye ekhaya naphesheya abenza umsebenzi wokukhiqiza, ukuhlanganisa, ukucubungula izinto zikagesi.

▍Isu kanye nendlela yesitifiketi sokuphepha:

Faka isicelo sesitifiketi se-KC esinemodeli yomkhiqizo engahlukaniswa ngemodeli eyisisekelo kanye nemodeli yochungechunge.

Ukuze kucaciswe uhlobo lwemodeli kanye nomklamo wezinto zikagesi, igama lomkhiqizo eliyingqayizivele lizonikezwa ngokomsebenzi wawo ohlukile.

▍ Isitifiketi se-KC sebhethri ye-Lithium

1. Izinga lesitifiketi se-KC sebhethri ye-lithium:I-KC62133:2019
2. Ububanzi bomkhiqizo wesitifiketi se-KC sebhethri ye-lithium

A. Amabhethri e-lithium yesibili azosetshenziswa kuhlelo lokusebenza oluphathekayo noma kumadivayisi akhiphekayo

B. Iseli alikho ngaphansi kwesitifiketi se-KC ukuthi liyathengiswa noma lihlanganiswe ngamabhethri.

C. Kumabhethri asetshenziswa kudivayisi yokugcina amandla noma i-UPS (ugesi ongaphazamiseki), namandla awo angaphezu kuka-500Wh angaphezu komthamo.

D. Ibhethri ubukhulu bawo amandla evolumu bungaphansi kuka-400Wh/L iza esikhaleni sesitifiketi kusukela ngo-1.^st, Ephreli 2016.

▍Kungani i-MCM?

● I-MCM igcina ukubambisana okuseduze namalebhu ase-Korea, njenge-KTR (Korea Testing & Research Institute) futhi iyakwazi ukunikeza izixazululo ezingcono kakhulu ngokusebenza kwezindleko eziphakeme kanye nesevisi Yokwengeza Inani kumakhasimende kusukela endaweni yesikhathi sokuhola, inqubo yokuhlola, ukunikezwa isitifiketi. izindleko.

● Isitifiketi se-KC sebhethri ye-lithium eshajwayo singatholwa ngokuthumela isitifiketi se-CB futhi sisiguqulele kusitifiketi se-KC. Njenge-CBTL ngaphansi kwe-TÜV Rheinland, i-MCM inganikeza imibiko nezitifiketi ezingase zisetshenziswe ekuguqulelweni kwesitifiketi se-KC ngokuqondile. Futhi isikhathi sokuhola singafinyezwa uma usebenzisa i-CB ne-KC ngesikhathi esifanayo. Ngaphezu kwalokho, intengo ehlobene izoba yinhle kakhulu.

Amabhethri e-lithium-ion asetshenziswe kabanzi njengamabhethri aphinde ashajwe kusukela ngeminyaka yawo-1990s ngenxa yomthamo wawo ophezulu obuyiselekayo kanye nokuzinza komjikelezo. Ngokukhula okukhulu kwentengo ye-lithium kanye nesidingo esikhulayo se-lithium nezinye izingxenye eziyisisekelo zamabhethri e-lithium-ion, ukushoda okwandayo kwezinto zokusetshenziswa ezikhuphukayo zamabhethri e-lithium kusiphoqa ukuthi sihlole amasistimu e-electrochemical amasha nashibhile asekelwe ezintweni eziningi ezikhona. . Amabhethri e-sodium-ion abiza kancane ayindlela engcono kakhulu. Ibhethri ye-sodium ion cishe yatholakala kanye nebhethri ye-lithium-ion, kodwa ngenxa yobubanzi bayo obukhulu be-ion namandla aphansi, abantu bathambekele kakhulu ekufundeni ugesi we-lithium, kanye nocwaningoibhethri ye-sodium-ionicishe ima. Ngokukhula okusheshayo kwezimoto zikagesi kanye nemboni yokugcina amandla eminyakeni yamuva, iibhethri ye-sodium-ion, eye yahlongozwa ngesikhathi esifanayo nebhethri ye-lithium-ion, isiphinde yadonsa ukunaka kwabantu.
I-lithium, i-sodium ne-potassium zonke izinsimbi ze-alkali kuthebula le-periodic lezinto. Zinezici ezifanayo zomzimba namakhemikhali futhi zingasetshenziswa njengezinto zebhethri yesibili ngokombono. Imithombo ye-sodium inothe kakhulu, isatshalaliswa kabanzi kuqweqwe loMhlaba futhi kulula ukuyikhipha. Njengengxenye ye-lithium, i-sodium iye yanakwa kakhulu emkhakheni webhethri. Abakhiqizi bamabhethri bayaklolodela ukwethula umzila wobuchwepheshe webhethri le-sodium-ion. Imibono Eqondisayo Ekusheshiseni Ukuthuthukiswa Kwesitoreji Esisha Samandla, Uhlelo Lokusungula Ezesayensi Nobuchwepheshe Emkhakheni Wezamandla ngesikhathi seNkathi Yohlelo Lweminyaka eyi-14, kanye Nokuqaliswa Kohlelo Lokuthuthukiswa Kwesitoreji Samandla Esisha phakathi Nenkathi YoHlelo Lweminyaka eyi-14 olukhishwe Ikhomishana Kazwelonke Yokuthuthukiswa Nezinguquko kanye Nokuphathwa Kwezamandla Kazwelonke bakhulume ukuthuthukisa isizukulwane esisha sobuchwepheshe bokugcina amandla obusebenza kahle njengamabhethri e-sodium-ion. I-Ministry of Industry and Information Technology (MIIT) iphinde yakhuthaza amabhethri amasha, njengamabhethri e-sodium-ion, njenge-ballast yokuthuthukisa imboni yamandla entsha. Izindinganiso zemboni zamabhethri e-sodium-ion nazo ziyasebenza. Kulindeleke ukuthi njengoba imboni ikhulisa utshalomali, ubuchwepheshe buvuthwa futhi uchungechunge lwezimboni luyathuthukiswa kancane kancane, ibhethri le-sodium-ion elisebenza ngezindleko eziphakeme kulindeleke ukuthi libe yingxenye yemakethe yebhethri ye-lithium-ion.I-aluminium foil ingasetshenziswa njengomqoqi wamanje we-electrode enhle nengalungile yamabhethri e-sodium-ion. Amabhethri e-lithium-ion anamandla aphansi angalungile futhi kufanele asebenzise i-copper foil engagqwalile. Amabhethri e-sodium-ion, ngakolunye uhlangothi, anamandla aphezulu angalungile, ngakho awahlanganisi ne-sodium. Ucwecwe lwe-aluminium luncane ngesisindo futhi lubiza kune-copper foil.
