▍Siyini Isitifiketi Se-CB?

I-IECEE CB iwuhlelo lokuqala lwangempela lwamazwe ngamazwe lokuqashelwa ngokufanayo kwemibiko yokuhlolwa kokuphepha kwezinto zikagesi.I-NCB (National Certification Body) ifinyelela isivumelwano sezizwe eziningi, esivumela abakhiqizi ukuthi bathole isitifiketi sikazwelonke kwamanye amazwe angamalungu ngaphansi kohlelo lwe-CB ngesisekelo sokudlulisa esinye sezitifiketi ze-NCB.

Isitifiketi se-CB siwumbhalo osemthethweni wohlelo lwe-CB okhishwe i-NCB egunyaziwe, okokwazisa enye i-NCB ukuthi amasampula omkhiqizo ohloliwe ahambisana nezidingo ezijwayelekile.

Njengohlobo lombiko omisiwe, umbiko we-CB ubala izidingo ezifanele ezivela entweni ejwayelekile ye-IEC ngento ngayinye.Umbiko we-CB awuhlinzeki nje kuphela ngemiphumela yakho konke ukuhlolwa okudingekile, ukukalwa, ukuqinisekiswa, ukuhlolwa nokuhlola ngokucacile nokungacacisi, kodwa futhi kufaka phakathi izithombe, umdwebo wesifunda, izithombe nencazelo yomkhiqizo.Ngokomthetho wohlelo lwe-CB, umbiko we-CB ngeke usebenze kuze kube yilapho wethula isitifiketi se-CB ndawonye.

▍Kungani sidinga Isitifiketi se-CB?

1. Ngqolyqaphelazed or vumaedngeilunguamazwe

Ngesitifiketi se-CB kanye nombiko wokuhlola we-CB, imikhiqizo yakho ingathunyelwa kwamanye amazwe ngokuqondile.

1. Guqulela kwamanye amazwe izitifiketi

Isitifiketi se-CB singaguqulelwa ngokuqondile kusitifiketi samazwe angamalungu ayo, ngokunikeza isitifiketi se-CB, umbiko wokuhlola kanye nombiko wokuhlola umehluko (uma kusebenza) ngaphandle kokuphinda ukuhlolwa, okunganciphisa isikhathi sokuhola sokuthola isitifiketi.

1. Qinisekisa Ukuphepha Komkhiqizo

Ukuhlolwa kwesitifiketi se-CB kubheka ukusetshenziswa okuphusile komkhiqizo kanye nokuphepha okubonakalayo uma usetshenziswa kabi.Umkhiqizo oqinisekisiwe ufakazela ukugculisa kwezidingo zokuphepha.

▍Kungani i-MCM?

● Ukufaneleka:I-MCM iyi-CBTL yokuqala egunyaziwe ye-IEC 62133 ejwayelekile yi-TUV RH ezweni laseChina.

● Isitifiketi namandla okuhlola:I-MCM iphakathi kwesiqephu sokuqala sokuhlola nesitifiketi senkampani yangaphandle ye-IEC62133 ejwayelekile, futhi isiqede ukuhlola amabhethri e-IEC62133 angaphezu kuka-7000 kanye nemibiko ye-CB kumakhasimende omhlaba.

● Usekelo lobuchwepheshe:I-MCM inonjiniyela bezobuchwepheshe abangaphezu kwe-15 abakhethekile ekuhlolweni njengokujwayelekile kwe-IEC 62133.I-MCM ihlinzeka amakhasimende ngohlobo oluphelele, olunembile, oluvaliwe losekelo lobuchwepheshe kanye nezinsizakalo zolwazi ezihola phambili.

Ngo-1800, isazi sefilosofi sase-Italy u-A. Volta wakha inqwaba ye-voltaic, eyavula ukuqala kwamabhethri asebenzayo futhi yachaza ngokokuqala ngqa ukubaluleka kwe-electrolyte kumadivayisi okugcina amandla e-electrochemical.I-electrolyte ingabonakala njengesendlalelo se-electronic insulating kanye ne-ion-conducting ngendlela ewuketshezi noma eqinile, efakwe phakathi kwama-electrode angalungile kanye nama-positive.Njengamanje, i-electrolyte ethuthuke kakhulu yenziwa ngokuncibilikisa usawoti we-lithium oqinile (isb.Njengokwefomu leseli elijwayelekile kanye nomklamo, i-electrolyte ngokuvamile ithatha u-8% kuya ku-15% wesisindo seseli.Ngaphezu kwalokho, ukuvutha kwayo kanye nezinga lokushisa elilungile lokusebenza lika -10°C kuya ku-60°C kuphazamisa kakhulu ukuthuthukiswa okuqhubekayo kokuminyana kwamandla ebhethri nokuphepha.Ngakho-ke, ukwakheka okusha kwe-electrolyte kuthathwa njengokuvula amandla okubalulekile ekuthuthukisweni kwesizukulwane esilandelayo samabhethri amasha.Abacwaningi futhi basebenzela ukuthuthukisa amasistimu e-electrolyte ahlukene.Isibonelo, ukusetshenziswa kwezinyibilikisi ezine-fluorinated ezingafinyelela ukusebenza kahle kwe-lithium metal cycling, i-organic or inorganic solid electrolyte eyinzuzo embonini yezimoto kanye "namabhethri e-solid state" (SSB).Isizathu esiyinhloko ukuthi uma i-electrolyte eqinile ithatha indawo ye-electrolyte yokuqala yoketshezi kanye ne-diaphragm, ukuphepha, ukuminyana kwamandla kanye nempilo yebhethri kungathuthukiswa kakhulu.Okulandelayo, sifingqa ngokuyinhloko inqubekelaphambili yocwaningo lwama-electrolyte aqinile ngezinto ezahlukahlukene.
Ama-electrolyte aqinile angaphili asetshenziswe kumishini yokugcina amandla kagesi we-electrochemical, njengamabhethri ashisekayo ashisekayo aphezulu i-Na-S, amabhethri e-Na-NiCl2 namabhethri ayinhloko e-Li-I2.Emuva ngo-2019, u-Hitachi Zosen (Japan) wabonisa ibhethri lesikhwama sesikhwama esiqinile esingu-140 mAh elizosetshenziswa emkhathini futhi lihlolwe ku-International Space Station (ISS).Leli bhethri lakhiwe i-sulfide electrolyte nezinye izingxenye zebhethri ezingadalulwanga, ezikwazi ukusebenza phakathi kuka -40°C no-100°C.Ngo-2021 inkampani yethula ibhethri eliqinile elinamandla angu-1,000 mAh.U-Hitachi Zosen ubona isidingo samabhethri aqinile ezindaweni ezinokhahlo njengesikhala nemishini yezimboni esebenza endaweni evamile.Inkampani ihlela ukuphinda kabili umthamo webhethri ngo-2025. Kodwa kuze kube manje, awukho umkhiqizo webhethri wesimo esiqinile ongasetshenziswa ezimotweni zikagesi.
