▍Shahaadada MIC ee Vietnam

Wareegtada 42/2016/TT-BTTTT ayaa qeexaysa in baytariyada ku rakiban talefannada gacanta, tablets-ka iyo buugaagta wax lagu qoro aan loo dhoofin Vietnam haddii aan la marin shahaadada DoC tan iyo Oct.1,2016. DoC sidoo kale waxaa looga baahan doonaa inay bixiso marka la codsanayo Nooca Oggolaanshaha ee alaabta dhamaadka ah (telefoonada gacanta, tablet-yada iyo buugaagta xusuus qorka).

MIC waxay soo saartay Wareegto cusub 04/2018/TT-BTTTT bishii Maajo,2018 taas oo qeexaysa in aan mar dambe IEC 62133:2012 warbixin ay soo saartay shaybaadhka la aqoonsan yahay ee dibadda la aqbalay July 1, 2018. Imtixaanka maxalliga ahi waa lama huraan marka la codsanayo shahaadada ADoC.

Heerka Imtixaanka

QCVN101:2016/BTTTT (tixraac IEC 62133:2012)

▍PQIR

Dowladda Vietnam ayaa soo saartay amar cusub oo lambarkiisu yahay 74/2018 / ND-CP May 15, 2018 si ay u qeexdo in laba nooc oo badeecooyin ah oo la keeno Vietnam ay ku xiran yihiin codsiga PQIR (Diiwaangelinta Tayada Alaabta) marka loo soo dhoofiyo Vietnam.

Iyada oo ku saleysan sharcigan, Wasaaradda Warfaafinta iyo Isgaarsiinta (MIC) ee Vietnam waxay soo saartay dukumeenti rasmi ah 2305/BTTTT-CVT Julaay 1, 2018, taasoo qeexaysa in alaabada ay maamusho (oo ay ku jiraan baytariyada) waa in lagu codsadaa PQIR marka la soo dejinayo galay Vietnam. SdoC waa in la soo gudbiyaa si loo dhamaystiro nidaamka fasaxida kastamka. Taariikhda rasmiga ah ee uu dhaqan gelayo xeerkani waa Agoosto 10, 2018. PQIR waxay khusaysaa hal mar oo loo soo dhoofiyo Vietnam, taas oo ah, mar kasta oo soodejiye alaab soo dejiyo, waa inuu dalbadaa PQIR (baaritaan dufcad) + SdoC.

Si kastaba ha ahaatee, kuwa soo dajiyaasha ah ee degdega u ah inay alaab la'aan SDOC soo dejiyaan, VNTA waxay si ku meel gaar ah u xaqiijin doontaa PQIR waxayna fududayn doontaa fasaxa kastamka. Laakin soo dejiyeyaashu waxay u baahan yihiin inay u soo gudbiyaan SdoC VNTA si ay u dhamaystiraan dhammaan nidaamka banaynta kastamka 15 maalmood oo shaqo gudahooda kadib fasaxa kastamka. (VNTA mar dambe ma soo saari doonto ADOC-gii hore kaas oo kaliya lagu dabaqi karo Warshadaha Maxalliga ah ee Vietnam)

▍Waa maxay sababta MCM?

● Wadaaga xogtii ugu dambaysay

● Aasaasaha shaybaadhka tijaabada batteriga Quacert

MCM sidaas darteed wuxuu noqonayaa wakiilka kaliya ee shaybaadhkan ee Mainland China, Hong Kong, Macau iyo Taiwan.

● Adeegga Wakaalada Hal-Stop

MCM, oo ah wakaalad hal-joojin ah oo ku habboon, waxay siisa imtixaan, shahaado iyo adeeg wakiil macaamiisha.

Sanadkii 1800-kii, Fiisigiste Talyaani ah A. Volta wuxuu dhisay tuubada Voltaic-ka, kaas oo furay bilowga baytariyada wax ku oolka ah wuxuuna ku tilmaamay markii ugu horeysay muhiimada elektrolytka ee aaladaha kaydinta tamarta korantada. Electrolyte-ka waxa loo arki karaa in uu yahay lakabka korantada iyo ion-conducting qaab dareere ah ama adag, oo la geliyo inta u dhaxaysa electrodes-ka taban iyo kuwa togan. Waqtigan xaadirka ah, elektrolytka ugu horumarsan waxaa lagu sameeyaa iyada oo la milmaan milixda lithium adag (tusaale LiPF6) ee dareeraha kaarboonaytiga ee aan biyaha lahayn (tusaale EC iyo DMC). Sida ku cad qaabka guud iyo nashqadeynta unugga, korantada ayaa caadi ahaan xisaabisa 8% ilaa 15% miisaanka unugga. Intaa waxaa dheer, ololkeeda iyo heerkulka ugu wanaagsan ee heerkulka hawlgalka ee -10 ° C ilaa 60 ° C waxay si weyn u carqaladeynayaan horumarinta cufnaanta tamarta iyo badbaadada batteriga. Sidaa darteed, hababka cusub ee elektrolytka ayaa loo tixgeliyaa inay yihiin furaha u sahlaya horumarinta jiilka soo socda ee baytariyada cusub.Cilmi-baarayaashu waxay sidoo kale ka shaqeynayaan horumarinta hababka kala duwan ee elektrolytka. Tusaale ahaan, isticmaalka dareerayaasha fluorinated kuwaas oo gaari kara baaskiil bir lithium hufan, organic ama inorganic adag electrolytes faa'iido u ah warshadaha baabuurta iyo "Batteries adag state" (SSB). Sababta ugu weyn ayaa ah in haddii elektrolytka adag uu beddelo dareeraha asalka ah ee electrolyte iyo diaphragm, badbaadada, cufnaanta tamarta keliya iyo nolosha batteriga ayaa si weyn loo hagaajin karaa. Marka xigta, waxaanu inta badan soo koobaynaa horumarka cilmi-baarista ee electrolytes adag oo leh qalabyo kala duwan. . Dabayaaqadii 2019, Hitachi Zosen (Japan) wuxuu soo bandhigay baytari-kiish dawladeed oo dhan 140 mAh si loogu isticmaalo meel bannaan oo lagu tijaabiyo Saldhigga Hawada Caalamiga ah (ISS). Baytarigu wuxuu ka kooban yahay sulfide electrolyte iyo qaybo kale oo baytari ah oo aan la shaacin, isagoo awood u leh inuu shaqeeyo inta u dhaxaysa -40 ° C iyo 100 ° C. 2021 shirkaddu waxay soo bandhigaysaa batari adag oo awood sare leh oo ah 1,000 mAh. Hitachi Zosen wuxuu arkaa baahida baytariyada adag ee jawiga adag sida meel bannaan iyo qalabka warshadaha ee ka shaqeeya jawi caadi ah. Shirkaddu waxay qorshaynaysaa inay labanlaabto awoodda baytari marka la gaadho 2025. Laakiin ilaa hadda, ma jiro badeeco ka baxsan shelf-ka-dhammaan batari dawladeed oo loo isticmaali karo baabuurta korantada.
