Ethyl methyl carbonateHe matū waro te matū nei, ko te tātai matū ko C5H8O3, e mōhiotia ana ko te EMC. He wai kore tae, mārama, he pūngāwerewere hoki, he iti te paitini me te pūngāwerewere. He mea whakamahi noa te EMC hei rauemi mata i roto i ngā mara pēnei i ngā whakarewa, ngā paninga, ngā kirihou, ngā kapia, ngā mea kakara, me ngā rongoā. Ka taea hoki te whakamahi hei whakarite i ētahi atu matū waro, pēnei i te polycarbonate. I roto i te hanga ahumahi, ko te hanga EMC he tikanga whakamahi i te tauhohenga whakawhiti ester, te tauhohenga esterification waro rānei.

Ko te mara tono o muri o te EMC ko te electrolyte pākahiko lithium-ion, ko tētahi o ngā rauemi matua e whā o ngā pākahiko lithium-ion, ā, e kiia nei ko te "toto" o ngā pākahiko.
E rua ngā wāhanga o te EMC i runga i te parakore: te methyl ethyl carbonate o te taumata ahumahi (99.9%) me te EMC o te taumata pākahiko (99.99% neke atu rānei). Ko te EMC o te taumata ahumahi te mea e whakamahia nuitia ana i roto i te hanga matū ahumahi me ngā whakarewa; ko te tukanga EMC o te taumata pākahiko e hiahia ana ki ngā whakaritenga teitei ake, ā, e whakamahia nuitia ana hei whakarewa mō ngā electrolytes pākahiko lithium-ion. Nā te iti o te aukati steric me te kore taurite o te hanganga, ka taea e ia te āwhina ki te whakanui ake i te wairewatanga o ngā katote lithium, te whakapai ake i te kiato capacitance me te utu o te pākahiko, ā, kua noho ko tētahi o ngā whakarewa matua e rima mō ngā electrolytes pākahiko lithium-ion.
Ko te mara tono o te EMC i raro iho ko te electrolyte pākahiko lithium-ion, ko tētahi o ngā rauemi matua e whā o ngā pākahiko lithium-ion, ā, e kiia ana ko te "toto" o ngā pākahiko. I ngā tau tata nei, me te tere o te whanaketanga o te umanga waka hiko hou, kua uru te umanga electrolyte pākahiko lithium-ion o Haina ki tētahi wā tere o te whanaketanga. Kua tino piki ake te tere o te rohe o ngā electrolyte, ā, kua tutuki te whakakapinga kawemai, e akiaki ana i te tere o te tipu o te tono mō te EMC i te mākete o Haina. E ai ki te "2023-2027 China EMC Industry Market Deep Research and Development Prospects Forecast Report" i tukuna e te Xinsijie Industry Research Center, i te tau 2021, ko te tono mō te EMC i Haina he 139500 tana, he pikinga tau-ki-te-tau o te 94.7%.
Te mākete mōEMCkua whakaatu i tētahi ia tipu pumau i ngā tau kua taha ake nei. Ko te take nui o tēnei ko te whakamahinga whānui o te EMC i roto i ngā momo mahi ahumahi, pērā i ngā whakarewa, ngā paninga, ngā kirihou, ngā kapia, ngā mea kakara, me ngā rongoā. Hei tāpiri, me te whanaketanga o te ōhanga o te ao me te whakapainga o ngā paerewa oranga o te tangata, kei te piki haere hoki te hiahia mō te EMC.
I tēnei wā, ko ngā rohe kaihoko matua o te mākete EMC ko te rohe o Āhia me te Moana-nui-a-Kiwa, o Ūropi, me Amerika Te Raki. Ko te rohe o Āhia me te Moana-nui-a-Kiwa te rohe kaihoko matua o te mākete methyl ethyl carbonate, ko Haina, ko Hapani, me Kōrea ki te Tonga ngā kaihanga me ngā kaihoko matua o te EMC. Kei te tipu haere hoki te mākete mō te EMC i Ūropi me Amerika Te Raki, ko Tiamana, te United Kingdom, te United States, me Kānata ngā kaihoko matua o te EMC.
I ngā rā kei te heke mai, ka pāngia te tipu o te mākete EMC e te whanaketanga ōhanga me te ahumahi o te ao. I te pikinga ake o ngā mākete hou me te ahunga whakamua tonu o te hangarau, ka piki tonu te hiahia mō te EMC i te mākete. Hei tāpiri, ka noho ko te tiaki taiao me te whanaketanga tauwhiro hei au nui i roto i te mākete EMC, e whakatairanga ana i te whakaputa me te whakamahi i te EMC kia pai ake te taiao me te tauwhiro.
