Txheej txheem cej luam ntawm txoj kev loj hlob ntawmLithium roj teeb electrolyte,
Lithium roj teeb electrolyte,

▍Vietnam MIC Certification

Circular 42/2016/TT-BTTTT tau teev tseg tias cov roj teeb uas tau teeb tsa hauv lub xov tooj ntawm tes, ntsiav tshuaj thiab phau ntawv sau tsis raug tso cai xa tawm mus rau Nyab Laj tshwj tsis yog lawv raug DoC daim ntawv pov thawj txij thaum Lub Kaum Hli 1, 2016. DoC kuj tseem yuav tsum tau muab thaum thov Kev Pom Zoo Hom rau cov khoom kawg (cov xov tooj ntawm tes, ntsiav tshuaj thiab phau ntawv sau).

MIC tau tshaj tawm tsab xov xwm tshiab 04/2018/TT-BTTTT nyob rau lub Tsib Hlis, 2018 uas tau teev tseg tias tsis muaj IEC 62133: 2012 tshaj tawm tsab ntawv tshaj tawm los ntawm cov chaw kuaj xyuas txawv teb chaws raug lees txais thaum Lub Xya Hli 1, 2018. Kev sim hauv zos yog qhov tsim nyog thaum thov rau ADoC daim ntawv pov thawj.

▍ Test Standard

QCVN101: 2016 / BTT (saib rau IEC 62133: 2012)

▍ PQIR

Tsoom Fwv Teb Chaws Nyab Laj tau tshaj tawm tsab cai tshiab No.

Raws li txoj cai lij choj no, Ministry of Information thiab Communication (MIC) ntawm Nyab Laj tau tshaj tawm cov ntaub ntawv raug cai 2305 / BTTTT-CVT thaum Lub Xya Hli 1, 2018, qhia tias cov khoom hauv qab nws tswj (xws li roj teeb) yuav tsum tau thov rau PQIR thaum raug xa tawm. mus rau Nyab Laj. SDoC yuav tsum raug xa mus ua kom tiav cov txheej txheem kev lis kev cai. Hnub kawg ntawm kev nkag mus rau hauv cov cai no yog lub Yim Hli 10, 2018. PQIR muaj feem xyuam rau ib qho kev ntshuam mus rau Nyab Laj, uas yog, txhua zaus tus neeg xa khoom tuaj txawv teb chaws, nws yuav tsum thov rau PQIR (batch tshuaj xyuas) + SDoC.

Txawm li cas los xij, rau cov neeg lag luam uas tau ceev nrooj xa cov khoom tsis muaj SDOC, VNTA yuav tshawb xyuas PQIR ib ntus thiab pab txhawb kev lis kev cai. Tab sis cov neeg xa khoom yuav tsum xa SDoC rau VNTA kom ua tiav tag nrho cov txheej txheem kev lis kev cai tsis pub dhau 15 hnub ua haujlwm tom qab kev lis kev cai. (VNTA yuav tsis muab ADOC yav dhau los uas tsuas yog siv tau rau Nyab Laj Hauv Zos Cov Chaw Tsim Khoom)

▍ Vim li cas MCM?

● Qhia tawm cov ntaub ntawv tshiab

● Co-founder ntawm Quacert roj teeb kuaj kuaj

MCM yog li dhau los ua tus neeg sawv cev ntawm lub chaw sim no hauv Mainland Tuam Tshoj, Hong Kong, Macau thiab Taiwan.

● Ib-stop Agency Service

MCM, ib qho chaw ua haujlwm zoo tshaj plaws rau ib qho chaw, muab kev sim, ntawv pov thawj thiab kev pabcuam tus neeg sawv cev rau cov neeg siv khoom.

Nyob rau hauv 1800, tus Italian physicist A. Volta tau tsim lub voltaic pawg, uas tau qhib qhov pib ntawm lub tswv yim roj teeb thiab piav rau thawj lub sij hawm qhov tseem ceeb ntawm electrolyte nyob rau hauv electrochemical zog cia li. Cov electrolyte tuaj yeem pom tau tias yog ib qho hluav taws xob insulating thiab ion-conducting txheej nyob rau hauv daim ntawv ntawm cov kua los yog khoom, ntxig rau ntawm qhov tsis zoo thiab zoo electrodes. Tam sim no, cov khoom siv hluav taws xob zoo tshaj plaws yog tsim los ntawm kev ua kom cov roj lithium ntsev (xws li LiPF6) hauv cov kuab tshuaj organic carbonate uas tsis muaj dej (xws li EC thiab DMC). Raws li cov qauv ntawm tes thiab tsim qauv, cov electrolyte feem ntau suav rau 8% mus rau 15% ntawm qhov hnyav ntawm tes. Dab tsi ntxiv, nws qhov flammability thiab pom kev ua haujlwm kub ntawm -10 ° C txog 60 ° C zoo heev cuam tshuam kev txhim kho ntxiv ntawm roj teeb lub zog ceev thiab kev nyab xeeb. Yog li ntawd, cov txheej txheem tshiab electrolyte raug suav tias yog qhov tseem ceeb rau kev txhim kho cov roj teeb tshiab tiam tom ntej. Cov kws tshawb fawb kuj tseem ua haujlwm los tsim cov tshuab electrolyte sib txawv. Piv txwv li, kev siv cov kuab tshuaj fluorinated uas muaj peev xwm ua tau zoo lithium hlau cycling, organic lossis inorganic khoom electrolytes uas muaj txiaj ntsig zoo rau kev lag luam tsheb thiab "cov roj teeb hauv lub xeev" (SSB). Lub ntsiab yog vim li cas yog hais tias cov khoom electrolyte hloov cov thawj cov kua electrolyte thiab diaphragm, kev nyab xeeb, ib lub zog ceev thiab lub neej ntawm lub roj teeb yuav ua tau zoo dua. Tom ntej no, peb tsuas yog sau cov kev tshawb fawb ntawm cov khoom electrolytes nrog cov khoom sib txawv.Inorganic khoom electrolytes tau siv nyob rau hauv kev lag luam electrochemical zog cia li, xws li ib co high-temperature rechargeable roj teeb Na-S, Na-NiCl2 roj teeb thiab thawj Li-I2 roj teeb. . Rov qab rau xyoo 2019, Hitachi Zosen (Nyiv) tau nthuav tawm tag nrho cov khoom siv-lub xeev lub hnab roj teeb ntawm 140 mAh los siv rau hauv qhov chaw thiab sim ntawm International Chaw Nres Tsheb (ISS). Lub roj teeb no yog tsim los ntawm sulfide electrolyte thiab lwm yam roj teeb uas tsis tau qhia tawm, tuaj yeem ua haujlwm ntawm -40 ° C thiab 100 ° C. Hauv 2021 lub tuam txhab tab tom qhia lub peev xwm ntau dua cov roj teeb ntawm 1,000 mAh. Hitachi Zosen pom qhov kev xav tau ntawm cov roj teeb khoom siv rau qhov chaw hnyav xws li qhov chaw thiab cov cuab yeej siv ua haujlwm hauv ib puag ncig ib puag ncig. Lub tuam txhab npaj yuav muab ob npaug rau lub roj teeb muaj peev xwm los ntawm 2025. Tab sis txog tam sim no, tsis muaj cov khoom lag luam tawm hauv lub xeev cov roj teeb uas tuaj yeem siv rau hauv tsheb fais fab.
