Ebe EMC na-arụ ọrụ n'okpuru bụkarị lithium-ion batri electrolyte, nke bụ otu n'ime ihe anọ dị mkpa nke batrị lithium-ion ma a na-akpọ ya "ọbara" nke batrị.

EMC kewara ụzọ abụọ dabere na ịdị ọcha: ọkwa ụlọ ọrụ mmepụta ihe methyl ethyl carbonate (99.9%) na ọkwa batrị EMC (99.99% ma ọ bụ karịa). A na-ejikarị EMC ọkwa ụlọ ọrụ mmepụta ihe na mmepụta ihe ndị sitere na organic; Usoro EMC ọkwa batrị chọrọ ihe achọrọ dị elu ma a na-ejikarị ya eme ihe dị ka ihe mgbaze maka electrolytes batrị lithium-ion. N'ihi obere ihe mgbochi steric ya na enweghị nhazi ya, ọ nwere ike inye aka n'ịbawanye ike ịgbaze nke ion lithium, na-eme ka njupụta capacitance na chajị batrị dịkwuo mma, ọ ghọwokwa otu n'ime ihe mgbaze ise bụ isi maka electrolytes batrị lithium-ion.

Ihe dị mkpa n'iji EMC eme ihe bụ electrolyte batrị lithium-ion, nke bụ otu n'ime ihe anọ dị mkpa nke batrị lithium-ion ma a na-akpọ ya "ọbara" nke batrị.
