Ethyl methyl carbonateke motsoako oa lintho tse phelang o nang le foromo ea lik'hemik'hale ea C5H8O3, e tsejoang hape e le EMC. Ke mokelikeli o se nang 'mala, o bonaletsang, le o feto-fetohang o nang le chefo e tlase le ho feto-fetoha ha maemo. EMC e sebelisoa hangata e le thepa e tala masimong a kang li-solvents, li-coating, polasetiki, li-resin, linoko le meriana. E ka boela ea sebelisoa ho lokisa metsoako e meng ea lintho tse phelang, joalo ka polycarbonate. Tlhahisong ea indasteri, tlhahiso ea EMC hangata e amohela karabelo ea phapanyetsano ea ester kapa karabelo ea esterification ea carbonation.

Tšimo ea ts'ebeliso ea EMC e tlase haholo-holo ke electrolyte ea betri ea lithium-ion, e leng e 'ngoe ea thepa e mene e meholo ea libeteri tsa lithium-ion' me e bitsoa "mali" a libeteri.

EMC e arotsoe ka mekhahlelo e 'meli ho latela bohloeki: methyl ethyl carbonate ea sehlopha sa indasteri (99.9%) le EMC ea sehlopha sa betri (99.99% kapa ho feta). EMC ea sehlopha sa indasteri e sebelisoa haholo-holo tlhahisong ea lintho tse phelang tsa indasteri le li-solvents; Ts'ebetso ea EMC ea sehlopha sa betri e hloka litlhoko tse phahameng 'me e sebelisoa haholo-holo e le solvent bakeng sa li-electrolyte tsa betri ea lithium-ion. Ka lebaka la tšitiso ea eona e nyane ea steric le asymmetry sebopehong, e ka thusa ho eketsa ho qhibiliha ha li-ion tsa lithium, ho ntlafatsa bongata ba capacitance le tjhaja ea betri, 'me e fetohile e 'ngoe ea li-solvents tse hlano tse ka sehloohong bakeng sa li-electrolyte tsa betri ea lithium-ion.

Tšimo ea ts'ebeliso ea EMC e tlase haholo-holo ke electrolyte ea betri ea lithium-ion, e leng e 'ngoe ea lisebelisoa tse' nè tse kholo tsa libeteri tsa lithium-ion 'me e bitsoa ka ho hlaka "mali" a libeteri. Lilemong tsa morao tjena, ka nts'etsopele e potlakileng ea indasteri e ncha ea likoloi tsa motlakase, indasteri ea electrolyte ea libeteri ea lithium-ion ea Chaena e kene nakong ea nts'etsopele e potlakileng. Sekhahla sa libaka tsa li-electrolyte se eketsehile haholo, 'me phetoho ea kantle ho naha e fihletsoe, e leng se susumetsang kholo e potlakileng ea tlhoko ea EMC' marakeng oa Chaena. Ho ea ka "Tlaleho ea Ponelopele ea Patlisiso e Tebileng ea 'Maraka oa Indasteri ea China EMC ea 2023-2027" e lokollotsoeng ke Setsi sa Lipatlisiso sa Indasteri ea Xinsijie, ka 2021, tlhoko ea EMC Chaena e ne e le lithane tse 139500, keketseho ea selemo le selemo ea 94.7%.

'Maraka oaEMCe bontšitse mokhoa o tsitsitseng oa kholo lilemong tse 'maloa tse fetileng. Sena se bakoa haholo-holo ke tšebeliso e pharaletseng ea EMC lits'ebetsong tse fapaneng tsa indasteri, joalo ka li-solvents, li-coating, polasetiki, li-resin, linoko le meriana. Ho phaella moo, ka nts'etsopele ea moruo oa lefats'e le ntlafatso ea maemo a bophelo a batho, tlhoko ea EMC le eona e ntse e eketseha butle-butle.

Hona jwale, dibaka tse ka sehloohong tsa bareki ba mmaraka wa EMC di kenyeletsa sebaka sa Asia Pacific, Europe le Amerika Leboya. Sebaka sa Asia Pacific ke sebaka se ka sehloohong sa bareki ba mmaraka wa methyl ethyl carbonate, mme China, Japane le Korea Borwa ke bahlahisi le bareki ba ka sehloohong ba EMC. Mmaraka wa EMC Europe le Amerika Leboya le wona o ntse o hola butle-butle, mme Jeremane, United Kingdom, United States le Canada ke bareki ba ka sehloohong ba EMC.

Nakong e tlang, kgolo ya mmaraka wa EMC e tla susumetswa ke ntshetsopele ya moruo le diindasteri lefatsheng ka bophara. Ka ho phahama ha mebaraka e ntseng e hola le kgatelopele e tswelang pele ya theknoloji, tlhokeho ya EMC mmarakeng e tla tswela pele ho hola. Ho feta moo, tshireletso ya tikoloho le ntshetsopele e tswelang pele le tsona e tla ba mekgwa ya bohlokwa mmarakeng wa EMC, e leng se kgothaletsang tlhahiso le tshebediso ya EMC hore e be mosa tikolohong le e tswelang pele.
