▍ Chii chinonzi CB Certification?

IECEE CB ndiyo yekutanga yechokwadi yepasirese sisitimu yekuzivikanwa pamwe chete kwemagetsi emagetsi ekuchengetedza bvunzo mishumo.NCB (National Certification Body) inosvika pachibvumirano chenyika dzakawanda, icho chinoita kuti vagadziri vawane chitupa chenyika kubva kune dzimwe nyika nhengo pasi pechirongwa cheCB nechikonzero chekuendesa chimwe chezvitupa zveNCB.

Chitupa cheCB igwaro repamutemo reCB scheme rakapihwa neNCB ine mvumo, inova yekuzivisa imwe NCB kuti masampula echigadzirwa akaedzwa anowirirana nezvinodiwa zvakajairwa.

Serudzi rwemushumo wakamisikidzwa, mushumo weCB unonyora zvakakodzera zvinodiwa kubva kuIEC yakajairika chinhu nechinhu.Chirevo cheCB hachingopi mhedzisiro yezvese zvinodiwa kuyedzwa, kuyerwa, kuonesa, kuongorora uye kuongorora nekujeka uye kusanzwisisika, asi zvakare kusanganisira mafoto, dhizaini redunhu, mapikicha uye tsananguro yechigadzirwa.Zvinoenderana nemutemo weCB scheme, chirevo cheCB hachizoshanda kudzamara chaunza chitupa cheCB pamwechete.

▍ Nei tichida CB Certification?

1. Directlyrecognized or approvedbynhengonyika

Iine CB chitupa uye CB test report, zvigadzirwa zvako zvinogona kutumirwa kune dzimwe nyika zvakananga.

1. Shandura kune dzimwe nyika zvitupa

Chitupa cheCB chinogona kushandurwa zvakananga kuchitupa chenyika dzenhengo dzayo, nekupa chitupa cheCB, mushumo webvunzo uye mutsauko webvunzo mushumo (kana uchishanda) pasina kudzokorora bvunzo, izvo zvinogona kupfupisa nguva yekutungamira yechitupa.

1. Ita shuwa Kuchengetedzeka kweChigadzirwa

Iyo CB certification bvunzo inotarisa kushandiswa zvine musoro kwechigadzirwa uye chengetedzo inofanoona kana ikashandiswa zvisizvo.Chigadzirwa chakasimbiswa chinoratidza kugutsikana kwezvinodiwa zvekuchengetedza.

▍ Neiko MCM?

● Zvikwaniriso:MCM ndiyo yekutanga kupihwa mvumo CBTL yeIEC 62133 yakajairwa kufanirwa neTUV RH mudunhu reChina.

● Certification uye kuyedza kugona:MCM iri pakati pekutanga kuyedza uye certification yechitatu bato yeIEC62133 yakajairwa, uye yapedza zvinopfuura zviuru zvinomwe zvebhatiri IEC62133 kuyedza uye CB mishumo yevatengi vepasirese.

● Rutsigiro rwehunyanzvi:MCM ine anopfuura gumi nemashanu mainjiniya ane hunyanzvi mukuyedza sepaIEC 62133 standard.MCM inopa vatengi ruzivo rwakakwana, rwakakwana, rwakavharwa-loop yerutsigiro rwehunyanzvi uye inotungamira-kumucheto ruzivo masevhisi.

Muna 1800, nyanzvi yefizikisi yeItaly A. Volta yakavaka murwi wevoltaic, iyo yakazarura kutanga kwemabhatiri anoshanda uye yakatsanangura kwekutanga kukosha kwe electrolyte mumagetsi emagetsi ekuchengetedza magetsi.Iyo electrolyte inogona kuonekwa seyemagetsi insulating uye ion-conducting layer muchimiro chemvura kana yakasimba, inoiswa pakati pemagetsi asina kunaka uye akanaka.Parizvino, electrolyte yepamusorosoro inogadzirwa nekunyungudutsa yakasimba lithium munyu (eg LiPF6) mune isiri-aqueous organic carbonate solvent (eg EC uye DMC).Sekureva kwesero rese fomu uye dhizaini, iyo electrolyte inowanzoita 8% kusvika 15% yehuremu hwesero.Pamusoro pezvo, kupisa kwayo uye tembiricha yakakwana yekushanda kubva -10 ° C kusvika 60 ° C inotadzisa zvakanyanya kuvandudzwa kwesimba rebhatiri uye kuchengeteka.Naizvozvo, magadzirirwo matsva emagetsi emagetsi anoonekwa seanogonesa kugadzirwa kwechizvarwa chinotevera chemabhatiri matsva.Vaongorori vari kushandawo kugadzira masisitimu e electrolyte akasiyana.Semuyenzaniso, kushandiswa kwe fluorinated solvents iyo inogona kuita inobudirira lithium metal cycling, organic or inorganic solid electrolytes iyo inobatsira kumotokari yemotokari uye "solid state batteries" (SSB).Chikonzero chikuru ndechekuti kana iyo yakasimba electrolyte ikatsiva yekutanga mvura electrolyte uye diaphragm, chengetedzo, simba rimwechete uye hupenyu hwebhatiri hunogona kuvandudzwa zvakanyanya.Tevere, isu tinonyanya kupfupisa kufambira mberi kwekutsvagisa kwema electrolyte akasimba nezvinhu zvakasiyana.
Inorganic yakasimba maelectrolyte akashandiswa mukutengesa magetsi emagetsi ekuchengetedza magetsi mabhatiri, senge mamwe mabhatiri epamusoro-tembiricha anogona kugadzirwazve Na-S, Na-NiCl2 mabhatiri uye ekutanga Li-I2 mabhatiri.Kudzoka muna 2019, Hitachi Zosen (Japan) yakaratidza bhatiri rehomwe-yakasimba ye140 mAh kuti ishandiswe muchadenga uye kuedzwa paInternational Space Station (ISS).Bhatiri iri rine sulfide electrolyte nezvimwe zvinhu zvebhatiri zvisina kutaurwa, zvinokwanisa kushanda pakati -40°C ne100°C.Muna 2021 kambani iri kuunza bhatiri repamusoro rakasimba re1,000 mAh.Hitachi Zosen anoona kudiwa kwemabhatiri akasimba enzvimbo dzakaomarara senge nzvimbo uye zvigadzirwa zvemaindasitiri zvinoshanda munzvimbo dzakajairwa.Iyo kambani inoronga kuwedzera kaviri bhatiri simba ne 2025. Asi kusvika ikozvino, hapana kunze-kwe-sherufu yose-yakasimba-state bhatiri chigadzirwa chinogona kushandiswa mumagetsi emagetsi.
