Test mwero: GB31241-2014:Lithium ion maseru nemabhatiri anoshandiswa mumidziyo yemagetsi inotakurika - Chekuchengetedza zvinodiwa
Gwaro retifiketi: CQC11-464112-2015:Sekondari Bhatiri uye Bhatiri Pack Chengetedzo Yekuchengetedzeka Mitemo ye Inotakurika Electronic Devices
Background uye Zuva rekushandiswa
1. GB31241-2014 yakabudiswa musi wa5 Zvitath, 2014;
2. GB31241-2014 yakaitwa nemutemo musi wa1 Nyamavhuvhust, 2015.
3. Musi wa15 Gumiguru, 2015, Certification and Accreditation Administration yakapa chigadziriso chehunyanzvi pakuwedzera kuyedzwa mwero GB31241 yechikamu chakakosha che "bhatiri" redhiyo uye vhidhiyo michina, ruzivo rwemichina uye telecom terminal michina. Sarudzo iyi inoti mabhatiri e-lithium anoshandiswa muzvigadzirwa zviri pamusoro anofanirwa kuongororwa zvisina tsarukano maererano neGB31241-2014, kana kuwana chitupa chakasiyana.
Cherechedza: GB 31241-2014 chiyero chenyika chinomanikidzirwa. Zvese zvigadzirwa zve lithium bhatiri zvinotengeswa muChina zvinoenderana neGB31241 yakajairwa. Iyi chiyero ichashandiswa muzvirongwa zvitsva zvesampling zvenyika, purovhinzi uye yenzvimbo yekuongorora zvisina tsarukano.

▍ Neiko MCM?
● Kuzivikanwa kwekodzero: MCM irabhoritari yeCQC yakagamuchirwa uye yeCESI yakagamuchirwa laboratori. Chirevo chebvunzo chakapihwa chinogona kushandiswa zvakananga kuCQC kana CESI chitupa;
● Rutsigiro rwehunyanzvi: MCM ine GB31241 yakakwana yemidziyo yekuongorora uye yakashongedzerwa nevanopfuura gumi vane hunyanzvi matekinoroji kuti vaite tsvakiridzo yakadzama pahunyanzvi hwekuyedza, chitupa, kuongorora fekitori uye mamwe maitiro, ayo anogona kupa akanyatso uye akagadziridzwa GB 31241 certification masevhisi epasi rose. vatengi.
Muindasitiri yemotokari yemagetsi, ternary lithium mabhatiri uye lithium iron phosphate mabhatiri agara ari akatarisana nenhaurirano. Zvose zvine zvazvakanakira nezvazvakaipira. Iyo ternary lithium bhatiri ine yakakwira simba density, yakanaka yakaderera-tembiricha kuita, uye yakakwirira cruising range, asi mutengo unodhura uye hauna kugadzikana. LFP yakachipa, yakagadzikana, uye ine yakanaka yepamusoro-tembiricha kuita. Izvo zvisingabatsiri ndezvakashata zvishoma-tembiricha kuita uye kushomeka kwesimba. Mukugadzirisa mabhatiri maviri, nekuda kwemitemo yakasiyana uye zvido zvekusimudzira, mhando mbiri dzinotamba dzichirwisana kumusoro uye pasi. Asi zvisinei nekuti marudzi maviri aya anokura sei, kuchengetedza kuita ndicho chinhu chakakosha.
Lithium-ion mabhatiri anonyanya kuumbwa neagative electrode material, electrolyte uye positive electrode material. Chiitiko chemakemikari cheiyo negative electrode material graphite iri padyo neiyo yesimbi lithium mune inochaja state. Iyo firimu yeSEI iri pamusoro inoora pakupisa kwakanyanya, uye lithium ions yakaiswa mugraphite inobata ne electro lyte uye binder polyvinylidene fluoride kuti isunungure kupisa kwakawanda. Alkyl carbonate organic solutions inowanzoshandiswa se electrolytes, iyo inogona kupisa. Iyo yakanaka electrode zvinhu kazhinji ishanduko yesimbi oxide, ine yakasimba oxi dizing pfuma munzvimbo yakachajiwa, uye inoora nyore kuburitsa okisijeni pakupisa kwakanyanya. Iyo okisijeni yakasunungurwa inosangana neoxidation reaction ne electrolyte, uye inobva yabudisa huwandu hwekupisa.Saka, kubva pakuona kwezvinhu, lithiamu-ion mabhatiri ane ngozi yakasimba, kunyanya panyaya yekushungurudzwa, nyaya dzekuchengetedza dzinowedzera. prominent. Kuti titevedzere uye tienzanise kushanda kwemabhatiri maviri e-lithium-ion akasiyana pasi pemamiriro ekushisa, takaita inotevera nhanho yekupisa bvunzo.
