▍Yintoni iSatifikethi se-CB?

I-IECEE CB yinkqubo yokuqala yokwenyani yamazwe ngamazwe yokwamkelwa ngokufanayo kweengxelo zovavanyo lokhuseleko lwezixhobo zombane.I-NCB (i-National Certification Body) ifikelela kwisivumelwano samazwe amaninzi, esenza ukuba abavelisi bafumane isatifikethi sesizwe kwamanye amazwe angamalungu phantsi kwe-CB scheme ngesiseko sokudlulisela esinye sezatifikethi ze-NCB.

Isatifikethi se-CB luxwebhu lwesikimu se-CB esisesikweni esikhutshwe yi-NCB egunyazisiweyo, ekwazisa enye i-NCB ukuba iisampuli zemveliso ezivavanyiweyo ziyahambelana neemfuno ezisemgangathweni.

Njengohlobo lwengxelo esemgangathweni, ingxelo ye-CB idwelisa iimfuno ezifanelekileyo ukusuka kwinqaku le-IEC elisemgangathweni ngento.Ingxelo ye-CB ayinikezi kuphela iziphumo zazo zonke iimvavanyo ezifunekayo, ukulinganisa, ukuqinisekiswa, ukuhlolwa kunye nokuhlola ngokucacileyo kunye nokungacacisi, kodwa kubandakanywa neefoto, umzobo wesiphaluka, imifanekiso kunye nenkcazo yemveliso.Ngokomgaqo weskim se-CB, ingxelo yeCB ayizukusebenza de iveze nesatifikethi seCB kunye.

▍Kutheni sifuna iSiqinisekiso se-CB?

1. Ngqolyukuqondazed or imvumeedngeilunguamazwe

Ngesatifikethi se-CB kunye nengxelo yovavanyo lwe-CB, iimveliso zakho zinokuthunyelwa kumazwe athile ngokuthe ngqo.

1. Guqulela kwamanye amazwe izatifikethi

Isatifikethi se-CB sinokuguqulwa ngokuthe ngqo kwisatifikethi samazwe angamalungu ayo, ngokubonelela ngesatifikethi se-CB, ingxelo yovavanyo kunye nengxelo yokuvavanya umahluko (xa kufanelekile) ngaphandle kokuphinda uvavanyo, olunokunciphisa ixesha eliphambili lokuqinisekiswa.

1. Qinisekisa uKhuseleko lweMveliso

Uvavanyo lwesiqinisekiso se-CB luqwalasela ukusetyenziswa okufanelekileyo kwemveliso kunye nokhuseleko olubonakalayo xa lusetyenziswa kakubi.Imveliso eqinisekisiweyo ingqina ukuba iyanelisa iimfuno zokhuseleko.

▍Kutheni i-MCM?

● Isiqinisekiso:I-MCM yeyokuqala egunyazisiweyo ye-CBTL ye-IEC 62133 isiqinisekiso esisemgangathweni yiTUV RH kwilizwe laseTshayina.

● Isatifikethi kunye namandla okuvavanya:I-MCM iphakathi kwepatch yokuqala yovavanyo kunye nesiqinisekiso somntu wesithathu kumgangatho we-IEC62133, kwaye igqibe ngaphezu kwe-7000 yokuvavanya ibhetri ye-IEC62133 kunye neengxelo ze-CB kubathengi behlabathi.

● Inkxaso yobugcisa:I-MCM ineenjineli ezingaphezu kwe-15 zobuchwephesha ezikhethekileyo kuvavanyo ngokomgangatho we-IEC 62133.I-MCM ibonelela abathengi ngolwazi olubanzi, oluchanekileyo, oluvaliweyo lwenkxaso yobugcisa kunye neenkonzo zolwazi oluphambili.

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 ifezekise i-lithium ye-cycling esebenzayo ye-lithium, i-electrolyte ye-organic okanye i-inorganic solid solid 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 ikakhulu inkqubela yophando yee-electrolyte eziqinileyo ngezinto ezahlukeneyo.
Ii-electrolyte eziqinileyo ezingaphiliyo zisetyenzisiwe kurhwebo lwezixhobo zokugcina amandla e-electrochemical, ezifana nezinye iibhetri ezihlaziyiweyo ezinobushushu obuphezulu i-Na-S, i-Na-NiCl2 iibhetri kunye neebhetri eziphambili ze-Li-I2.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 yazisa ibhetri ephezulu 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.
