Ethyl methyl karubonatini ikinyabutabire cy’umwimerere gifite formula ya chimique C5H8O3, izwi kandi nka EMC. Ni ikinyabutabire kitagira ibara, gisobanutse, kandi gihindagurika cyane kandi gifite uburozi buke kandi kidahinduka. EMC ikunze gukoreshwa nk'ibikoresho fatizo mu bintu nk'ibinyabutabire, irangi, pulasitiki, resins, ibirungo, n'imiti. Ishobora kandi gukoreshwa mu gutegura ibindi bintu by’umwimerere, nka polycarbonate. Mu nganda, ikorwa rya EMC rikunze gukoresha uburyo bwo guhinduranya ester cyangwa uburyo bwo gupima kabone.

Izina ry'igicuruzwa: Ethyl methyl karubonate

CAS:623-53-0

Ifishi y'ibinyabutabire: C4H8O3

EINECS：433-480-9

Igice cyo hasi cya EMC gikoreshwa ahanini ni electrolyte ya bateri ya lithiamu-ion, ikaba ari imwe mu bintu bine by'ingenzi bigize bateri ya lithiamu-ion kandi izwi cyane nka "amaraso" ya bateri.

EMC igabanyijemo ibyiciro bibiri bishingiye ku buziranenge: methyl ethyl carbonate yo mu rwego rw'inganda (99.9%) na EMC yo mu rwego rwa bateri (99.99% cyangwa hejuru). EMC yo mu rwego rw'inganda ikoreshwa cyane cyane mu guhuza no gusya ibintu mu nganda; Uburyo bwa EMC yo mu rwego rwa bateri busaba ibisabwa byinshi kandi bukoreshwa cyane cyane nk'umusemburo wa electrolyte za bateri ya lithiamu-ion. Bitewe n'imbogamizi ntoya za steric hamwe n'imiterere idahuye, ishobora gufasha mu kongera ubushobozi bwo gushonga bwa lithiamu, kunoza ubushobozi bw'amashanyarazi n'umushari wa bateri, kandi yabaye imwe mu misemburo itanu y'ingenzi ya electrolyte za bateri ya lithiamu-ion.

Igice cyo hasi cya EMC gikoreshwa ahanini ni electrolyte ya lithium-ion, ikaba ari imwe mu bikoresho bine by’ingenzi bya bateri za lithium-ion kandi yitwa "amaraso" ya bateri. Mu myaka ya vuba aha, hamwe n’iterambere ryihuse ry’inganda nshya zikora ibinyabiziga bitanga ingufu, inganda za electrolyte za lithium-ion zo mu Bushinwa zinjiye mu gihe cy’iterambere ryihuse. Igipimo cy’aho electrolyte zishyirwa mu bikorwa cyariyongereye cyane, kandi gusimbuza ibicuruzwa biva mu mahanga byaragezweho, bituma isoko ry’Ubushinwa rizamuka cyane. Dukurikije "Raporo y’ubushakashatsi bwimbitse ku isoko ry’inganda za EMC mu Bushinwa ya 2023-2027" yashyizwe ahagaragara n’ikigo cy’ubushakashatsi ku nganda cya Xinsijie, mu 2021, icyifuzo cya EMC mu Bushinwa cyari toni 139500, ubwiyongere bw’umwaka ku mwaka bwa 94.7%.

Isoko ryaEMCbyagaragaje iterambere rirambye mu myaka mike ishize. Ibi biterwa ahanini n'ikoreshwa rya EMC mu nganda zitandukanye, nko mu bintu bishongesha, mu gusiga irangi, mu pulasitiki, mu birungo, mu birungo no mu miti. Byongeye kandi, hamwe n'iterambere ry'ubukungu bw'isi no mu iterambere ry'imibereho y'abaturage, icyifuzo cya EMC nacyo kirimo kwiyongera buhoro buhoro.

Kugeza ubu, uturere tw’abaguzi b’ingenzi ku isoko rya EMC turimo akarere ka Aziya Pasifika, Uburayi, na Amerika ya Ruguru. Akarere ka Aziya Pasifika ni ko gafite isoko rya methyl ethyl carbonate, aho Ubushinwa, Ubuyapani, na Koreya y'Epfo ari byo bitanga umusaruro n'abaguzi ba EMC. Isoko rya EMC mu Burayi na Amerika ya Ruguru naryo ririmo gukura buhoro buhoro, aho Ubudage, Ubwongereza, Leta Zunze Ubumwe za Amerika na Kanada ari byo bikoresha EMC.

Mu gihe kizaza, iterambere ry'isoko rya EMC rizaterwa n'iterambere ry'ubukungu n'inganda ku isi. Uko amasoko ari kuzamuka ndetse n'iterambere ry'ikoranabuhanga rikomeje, icyifuzo cya EMC ku isoko kizakomeza kwiyongera. Byongeye kandi, kurengera ibidukikije n'iterambere rirambye nabyo bizaba intambwe ikomeye ku isoko rya EMC, bigateza imbere umusaruro n'ikoreshwa rya EMC kugira ngo ibe nziza ku bidukikije kandi ikomeze kubaho.
