Intsimi yesicelo esisezantsi se-EMC ikakhulu yi-lithium-ion ibhetri ye-electrolyte, enye yezinto ezine eziphambili zeebhetri ze-lithium-ion kwaye zibizwa ngokucacileyo ngokuthi "igazi" leebhetri.

I-EMC yohlulwe yangamacandelo amabini asekelwe kubunyulu: ibakala leshishini le-methyl ethyl carbonate (99.9%) kunye nebakala lebhetri i-EMC (99.99% okanye ngaphezulu).I-EMC ye-Industrial grade isetyenziswa ikakhulu kwi-industrial organic synthesis kunye nezinyibilikisi;Inkqubo ye-EMC yomgangatho webhetri ifuna iimfuno eziphezulu kwaye isetyenziswa ikakhulu njenge-solvent ye-lithium-ion battery electrolytes.Ngenxa yesithintelo esincinci se-steric kunye ne-asymmetry kwisakhiwo, inokunceda ekwandiseni ukunyibilika kwe-lithium ion, ukuphucula ukuxinwa kwe-capacitance kunye nokuhlawuliswa kwebhetri, kwaye ibe yenye yezona zintlanu zokunyibilikisa i-lithium-ion ibhetri ye-electrolyte.

Intsimi yesicelo esezantsi ye-EMC ikakhulu yi-lithium-ion ibhetri ye-electrolyte, enye yezinto ezine eziphambili zeebhetri ze-lithium-ion kwaye zibizwa ngokucacileyo ngokuthi "igazi" leebhetri.Kwiminyaka yakutshanje, kunye nophuhliso olukhawulezayo lweshishini elitsha lezithuthi zamandla, ishishini laseTshayina i-lithium-ion ibhetri ye-electrolyte lingene kwixesha lophuhliso olukhawulezayo.Izinga le-electrolyte yasekhaya linyuke kakhulu, kwaye ukufakwa endaweni yokungenisa kuphunyeziwe, kuqhuba ukukhula okukhawulezayo kwemfuno ye-EMC kwimarike yaseTshayina.Ngokutsho kwe "2023-2027 China EMC Industry Market Deep Research and Development Prospects Reports Report" ekhutshwe yi-Xinsijie Industry Research Centre, ngo-2021, imfuno ye-EMC e-China yayiyi-139500 yeetoni, ukunyuka konyaka-ngonyaka kwe-94.7% .

Imarike yeI-EMCibonise ukukhula okuzinzileyo kule minyaka imbalwa idlulileyo.Oku kungenxa yokusetyenziswa ngokubanzi kwe-EMC kwizicelo ezahlukeneyo zemizi-mveliso, ezifana nezinyibilikisi, iingubo, iiplastiki, iirasi, iziqholo, kunye namayeza.Ukongeza, ngophuhliso loqoqosho lwehlabathi kunye nokuphuculwa kwemigangatho yokuphila kwabantu, imfuno ye-EMC nayo iyanda ngokuthe ngcembe.

Okwangoku, eyona mimandla yabathengi iphambili kwimakethi ye-EMC ibandakanya indawo yaseAsia Pacific, iYurophu, kunye noMntla Melika.Ummandla waseAsia Pacific ngowona mmandla uphambili wabathengi kwimakethi ye-methyl ethyl carbonate, kunye neTshayina, iJapan, kunye noMzantsi Korea abavelisi abaphambili kunye nabathengi be-EMC.Imakethi ye-EMC eYurophu naseMntla Melika nayo ikhula ngokuthe ngcembe, kunye neJamani, i-United Kingdom, i-United States, kunye neCanada ingabathengi abaphambili be-EMC.

Kwixesha elizayo, ukukhula kwemarike ye-EMC kuya kuphenjelelwa luphuhliso loqoqosho lwehlabathi kunye noshishino.Ngokunyuka kweemarike ezivelayo kunye nenkqubela phambili yetekhnoloji eqhubekayo, imfuno ye-EMC kwimarike iya kuqhubeka ikhula.Ukongeza, ukukhuselwa kokusingqongileyo kunye nophuhliso oluzinzileyo luya kuba yimizila ebalulekileyo kwimarike ye-EMC, ukukhuthaza ukuveliswa kunye nokusetyenziswa kwe-EMC ukuba ibe nobungane ngakumbi nokuzinzileyo.
