I-ethyl methyl carbonateiyinhlanganisela yezinto eziphilayo enefomula yamakhemikhali i-C5H8O3, eyaziwa nangokuthi i-EMC. Iwuketshezi olungenambala, olusobala, noluguquguqukayo olunobuthi obuphansi kanye nokuguquguquka. I-EMC ivame ukusetshenziswa njengezinto zokusetshenziswa emikhakheni efana nezinyibilikisi, izembozo, amapulasitiki, ama-resin, izinongo, kanye nemithi. Ingasetshenziswa futhi ukulungiselela amanye amakhemikhali ezinto eziphilayo, njenge-polycarbonate. Ekukhiqizweni kwezimboni, ukukhiqizwa kwe-EMC kuvame ukusebenzisa ukusabela kokushintshana kwe-ester noma ukusabela kwe-carbonation esterification.

Igama lomkhiqizo: I-Ethyl methyl carbonate

I-CAS：623-53-0

Ifomula yama-molecule：C4H8O3

I-EINECS：433-480-9

Insimu yokusetshenziswa kwe-EMC engezansi ikakhulukazi i-electrolyte yebhethri le-lithium-ion, okungenye yezinto ezine ezibalulekile zamabhethri e-lithium-ion futhi ibizwa ngokucacile ngokuthi “igazi” lamabhethri.

I-EMC ihlukaniswe ngezigaba ezimbili ngokusekelwe ekuhlanzekeni: i-methyl ethyl carbonate yezinga lezimboni (99.9%) kanye ne-EMC yezinga lebhethri (99.99% noma ngaphezulu). I-EMC yezinga lezimboni isetshenziswa kakhulu ekuhlanganisweni kwezinto eziphilayo zezimboni kanye nezinyibilikisi; Inqubo ye-EMC yezinga lebhethri idinga izidingo eziphakeme futhi isetshenziswa kakhulu njengesinyibilikisi sama-electrolyte ebhethri le-lithium-ion. Ngenxa yokuphazamiseka kwayo okuncane kwe-steric kanye nokungalingani kwesakhiwo, ingasiza ekwandiseni ukuncibilika kwama-ion e-lithium, ithuthukise ubuningi be-capacitance kanye nokushaja kwebhethri, futhi isibe ngesinye sezinyibilikisi ezinhlanu eziyinhloko zama-electrolyte ebhethri le-lithium-ion.

Insimu yokusetshenziswa kwe-EMC engezansi ikakhulukazi i-lithium-ion battery electrolyte, okungenye yezinto ezine ezinkulu zamabhethri e-lithium-ion futhi ibizwa ngokusobala ngokuthi “igazi” lamabhethri. Eminyakeni yamuva nje, ngentuthuko esheshayo yemboni yezimoto ezintsha zamandla, imboni ye-lithium-ion battery electrolyte yaseShayina ingene enkathini yentuthuko esheshayo. Izinga lokufakwa kwama-electrolyte endaweni ethile likhuphuke kakhulu, futhi ukufakwa esikhundleni kwamanye amazwe kuye kwafinyelelwa ngokuyisisekelo, okuqhuba ukukhula okusheshayo kwesidingo se-EMC emakethe yaseShayina. Ngokusho kwe-“2023-2027 China EMC Industry Market Deep Research and Development Prospects Report” eyakhishwa yi-Xisijie Industry Research Center, ngo-2021, isidingo se-EMC eShayina sasingamathani angu-139500, ukwanda konyaka nonyaka okungu-94.7%.

Imakethe yeI-EMCibonise ukukhula okuqhubekayo eminyakeni embalwa edlule. Lokhu kungenxa yokusetshenziswa kabanzi kwe-EMC ezisetshenziswa ezimbonini ezahlukahlukene, njengezinyibilikisi, izembozo, amapulasitiki, ama-resin, izinongo, kanye nemithi. Ngaphezu kwalokho, ngokuthuthuka komnotho womhlaba kanye nokuthuthukiswa kwezinga lokuphila labantu, isidingo se-EMC naso siyakhula kancane kancane.

Njengamanje, izindawo eziyinhloko zabathengi emakethe ye-EMC zifaka phakathi isifunda sase-Asia Pacific, iYurophu, kanye neNyakatho Melika. Isifunda sase-Asia Pacific yisifunda esiyinhloko sabathengi emakethe ye-methyl ethyl carbonate, kanti iShayina, iJapan, kanye neNingizimu Korea zingabakhiqizi abakhulu nabathengi be-EMC. Imakethe ye-EMC eYurophu naseNyakatho Melika nayo ikhula kancane kancane, kanti iJalimane, i-United Kingdom, i-United States, kanye neCanada zingabathengi abakhulu be-EMC.

Esikhathini esizayo, ukukhula kwemakethe ye-EMC kuzothonywa yintuthuko yezomnotho neyezimboni emhlabeni jikelele. Ngokukhula kwezimakethe ezisafufusa kanye nentuthuko eqhubekayo kwezobuchwepheshe, isidingo se-EMC emakethe sizoqhubeka nokukhula. Ngaphezu kwalokho, ukuvikelwa kwemvelo kanye nentuthuko eqhubekayo kuzoba yimikhuba ebalulekile emakethe ye-EMC, okukhuthaza ukukhiqizwa nokusetshenziswa kwe-EMC ukuze ibe nobungane nemvelo futhi iqhubeke isikhathi eside.
