▍ISikimu soBhaliso esiSinyanzelo (CRS)
UMphathiswa wezobuChwepheshe kunye nobuChwepheshe boLwazi ukhululiweI-Electronics & Information Technology Goods-iMfuneko kuMyalelo woBhaliso oluSinyanzelo I-Yaziswa ngo-7thNgoSeptemba, 2012, kwaye yaqala ukusebenza nge-3rdOctober, 2013. I-Electronics & Information Technology Products Requirement kuBhaliso oluSinyanzelo, into edla ngokubizwa ngokuba sisiqinisekiso se-BIS, ngokwenene ibizwa ngokuba yi-CRS yokubhalisa/isiqinisekiso. Zonke iimveliso zombane ezikwikhathalogu yemveliso yobhaliso esisinyanzelo engeniswe eIndiya okanye ethengiswa kwimarike yaseIndiya kufuneka ibhaliswe kwiBureau yeMigangatho yaseIndiya (BIS). NgoNovemba ka-2014, iintlobo ezili-15 zeemveliso ezibhalisiweyo ezinyanzelekileyo zongezwa. Iindidi ezintsha zibandakanya: iifowuni eziphathwayo, iibhetri, iibhanki zamandla, izixhobo zombane, izibane ze-LED kunye neetheminali zokuthengisa, njl.
▍ Umgangatho woVavanyo lwebhetri yeBIS
Iseli ye-nickel / ibhetri: IS 16046 (Icandelo 1): 2018/ IEC62133-1: 2017
Iseli yelithium / ibhetri: IS 16046 (Icandelo 2): 2018/ IEC62133-2: 2017
Iseli yemali/ibhetri ifakiwe kwiCRS.
▍Kutheni i-MCM?
● Besijonge kwisiqinisekiso sase-India ngaphezu kweminyaka emi-5 kwaye sincede umxhasi ukuba afumane ileta yokuqala yehlabathi ye-BIS yebhetri. Kwaye sinamava asebenzayo kunye noqokelelo oluluqilima lwezixhobo kwicandelo lezatifiketi ze-BIS.
● Amagosa aphezulu angaphambili eBureau of Indian Standards (BIS) aqeshwe njengabacebisi bezatifikethi, ukuqinisekisa ukusebenza kakuhle kwemeko kunye nokususwa komngcipheko wokucinywa kwenombolo yobhaliso.
● Sixhotyiswe ngezakhono eziqinileyo zokusombulula iingxaki kwisiqinisekiso, sidibanisa izixhobo zemveli eIndiya. I-MCM igcina unxibelelwano oluhle kunye nabasemagunyeni be-BIS ukubonelela abathengi ngeyona nto iphambili, eyona nkcazelo yobugcisa kunye neyona inegunya lesatifikethi kunye nenkonzo.
● Sikhonza iinkampani ezikhokelayo kumashishini ahlukeneyo kwaye sizuze igama elihle kwintsimi, esenza sithembeke kakhulu kwaye sixhaswe ngabaxhasi.
Kwimizi-mveliso yeemoto zamandla amatsha, iibhetri ze-lithium ze-ternary kunye neebhetri ze-lithium iron phosphate bezisoloko zijolisa kwingxoxo. Zombini zineengenelo kunye nezingeloncedo zazo. Ibhetri ye-lithium ye-ternary inobuninzi bamandla aphezulu, ukusebenza kakuhle kweqondo lokushisa eliphantsi, kunye noluhlu oluphezulu lokuhamba ngenqanawa, kodwa ixabiso liyabiza kwaye alizinzile. I-LFP itshiphu, izinzile, kwaye inomsebenzi olungileyo wobushushu obuphezulu. Izinto ezingeloncedo kukungaqhubi kakuhle kobushushu obuphantsi kunye nokuxinana kwamandla aphantsi.
Kwinkqubo yophuhliso lweebhetri ezimbini, ngenxa yemigaqo-nkqubo eyahlukeneyo kunye neemfuno zophuhliso, iindidi ezimbini zidlala ngokuchaseneyo phezulu nangaphantsi. Kodwa kungakhathaliseki ukuba ezi ntlobo zimbini zikhula njani, ukhuseleko
ukusebenza yeyona nto iphambili. Iibhetri ze-lithium-ion zenziwa ikakhulu ngezinto ezingalunganga ze-electrode, i-electrolyte kunye nezinto ezintle ze-electrode. Umsebenzi weekhemikhali we-graphite ye-electrode engalunganga isondele kwi-lithium yensimbi kwimeko ehlawulisiweyo. Ifilimu ye-SEI ebusweni iyancipha kwiqondo lokushisa eliphezulu, kwaye i-lithium ion efakwe kwi-graphite isabela nge-electro lyte kunye ne-binder polyvinylidene fluoride ukukhulula ubushushu obuninzi. Alkyl carbonate izisombululo eziphilayo ziqhele ukusetyenziswa njenge
electrolytes, ezinokutsha. Izinto ze-electrode ezintle zidla ngokuba yi-oxide yensimbi yenguqu, enepropathi eyomeleleyo ye-oxi dizing kwimo ehlawuliswayo, kwaye ichithwa ngokulula ukukhulula i-oksijini kwiqondo lokushisa eliphezulu. Ioksijini ekhutshiweyo ifumana i-oxidation reaction kunye ne-electrolyte, kwaye emva koko ikhuphe ubushushu obuninzi.
Ngoko ke, ukusuka kwindawo yokujonga izinto eziphathekayo, iibhetri ze-lithium-ion zinomngcipheko onamandla, ngakumbi kwimeko yokusetyenziswa kakubi, imiba yokhuseleko ibonakala ngakumbi. Ukuze ukulinganisa kunye nokuthelekisa ukusebenza kweebhetri ezimbini ze-lithium-ion ezahlukeneyo phantsi kweemeko eziphezulu zokushisa, senze olu vavanyo lulandelayo lokufudumeza.
