I-Ethyl methyl carbonateiyinhlanganisela yemvelo enefomula yamakhemikhali i-C5H8O3, eyaziwa nangokuthi i-EMC. Iwuketshezi olungenambala, olusobala, futhi oluguquguqukayo olunobuthi obuphansi kanye nokuguquguquka. I-EMC ivame ukusetshenziswa njengempahla eluhlaza emikhakheni efana nezinyibilikisi, okokugqoka, amapulasitiki, ama-resin, izinongo kanye nemithi. Ingasetshenziswa futhi ukulungisa amanye ama-organic compounds, njenge-polycarbonate. Emkhiqizweni wezimboni, ukukhiqizwa kwe-EMC kuvame ukusebenzisa ukusabela kokushintshisana kwe-ester noma ukusabela kwe-carbonation esterification.

Igama lomkhiqizo: Ethyl methyl carbonate

I-CAS:623-53-0

Ifomula yemolekyuli:C4H8O3

I-EINECS: 433-480-9

Inkambu yokusetshenziswa kwe-EMC engezansi komfula i-electrolyte yebhethri ye-lithium-ion, okungenye yezinto ezine ezinkulu zamabhethri e-lithium-ion futhi ibizwa ngokusobala ngokuthi “igazi” lamabhethri.

I-EMC ihlukaniswe yaba izigaba ezimbili ngokusekelwe ekuhlanzekeni: ibanga lezimboni i-methyl ethyl carbonate (99.9%) kanye nebanga lebhethri i-EMC (99.99% noma ngaphezulu). I-EMC yebanga lezimboni isetshenziswa kakhulu ekuhlanganiseni kwezinto eziphilayo nezincibilikisa; Inqubo ye-EMC yezinga lebhethri idinga izidingo eziphakeme futhi isetshenziswa kakhulu njengesixazululi sama-electrolyte ebhethri ye-lithium-ion. Ngenxa yesithiyo sayo esincane se-steric kanye ne-asymmetry esakhiweni, ingasiza ekwandiseni ukunyibilika kwe-lithium ion, ukuthuthukisa ukuminyana kwe-capacitance kanye nokushajwa kwebhethri, futhi isibe esinye sezinyibilikisi ezinhlanu eziyinhloko zama-electrolyte ebhethri ye-lithium-ion.

Inkambu yokusetshenziswa kwe-EMC engezansi komfula i-electrolyte yebhethri ye-lithium-ion, okungenye yezinto ezine ezinkulu zamabhethri e-lithium-ion futhi ibizwa ngokusobala ngokuthi “igazi” lamabhethri. Eminyakeni yamuva nje, ngokuthuthuka okusheshayo kwemboni yezimoto zamandla amasha, imboni yaseChina ye-lithium-ion battery electrolyte ingene esikhathini sokuthuthuka ngokushesha. Izinga lendawo lama-electrolyte lenyuke kakhulu, futhi ukushintshwa kokungenisa ezweni sekuzuziwe, okuqhubekisela phambili ukukhula okusheshayo kwesidingo se-EMC emakethe yaseChina. Ngokuvumelana ne "2023-2027 China EMC Industry Market Deep Research and Development Prospects Forecast Report" ekhishwe yiXinsijie Industry Research Center, ngo-2021, isidingo se-EMC eChina sasingamathani ayi-139500, okuwukunyuka konyaka ngama-94.7% .

Imakethe yeI-EMCikhombise ukukhula okuzinzile eminyakeni embalwa edlule. Lokhu kungenxa yokusetshenziswa okubanzi kwe-EMC ezinhlelweni ezahlukahlukene zezimboni, njengezincibilikisi, okokugqoka, amapulasitiki, ama-resin, izinongo kanye nemithi. Ngaphezu kwalokho, ngokuthuthuka komnotho womhlaba kanye nokuthuthukiswa kwamazinga okuphila abantu, isidingo se-EMC sikhula kancane kancane.

Njengamanje, izifunda zabathengi eziphambili zemakethe ye-EMC zifaka isifunda sase-Asia Pacific, iYurophu kanye neNyakatho Melika. Isifunda sase-Asia Pacific siyindawo enkulu yabathengi bemakethe ye-methyl ethyl carbonate, kanti iChina, iJapan kanye neSouth Korea ingabakhiqizi nabathengi abakhulu be-EMC. Imakethe ye-EMC eYurophu naseNyakatho Melika nayo ikhula kancane kancane, kanti iJalimane, i-United Kingdom, i-United States kanye neCanada kungabathengi abakhulu be-EMC.

Ngokuzayo, ukukhula kwemakethe ye-EMC kuzothonywa ukuthuthukiswa komnotho nezimboni emhlabeni jikelele. Ngokukhula kwezimakethe ezisafufusa kanye nenqubekelaphambili yezobuchwepheshe eqhubekayo, isidingo se-EMC emakethe sizoqhubeka nokukhula. Ukwengeza, ukuvikelwa kwemvelo kanye nentuthuko esimeme nakho kuzoba izitayela ezibalulekile emakethe ye-EMC, kugqugquzelwe ukukhiqizwa kanye nokusetshenziswa kwe-EMC ukuze kuhambisane nemvelo futhi kuqhubeke.
