Taa, site na mmụba nke ụgbọ ala ume ọhụrụ na-ewu ewu, oke na ịchaji ọsọ abụrụla ihe na-echegbu ndị na-azụ ahịa. Dị ka "obi" nke ụgbọ ala ume ọhụrụ, batrị lithium-ion na-ekpebi kpọmkwem oke ụgbọ ahụ na ịrụ ọrụ chaja. N'ime ihe ndị bụ isi nke batrị lithium-ion, electrolyte na-arụ ọrụ dị mkpa.

I. Ụkpụrụ na-arụ ọrụ nke batrị Lithium-ion na mkpa nke Electrolyte

Ụkpụrụ ọrụ nke batrị lithium-ion dị ka "oche na-ama jijiji". Mgbe ị na-akwụ ụgwọ, a na-ahapụ ion lithium site na electrode dị mma, na-agafe na nkesa ahụ, gaa na electrode na-adịghị mma na electrolyte, na n'ikpeazụ na-agbanye na electrode na-adịghị mma. N'oge a, electrode ọjọọ na-echekwa ike. Mgbe ị na-agbapụta, a na-ahapụ ion lithium site na electrode na-adịghị mma, laghachi na electrode dị mma site na electrolyte, ma hapụ ike. Enwere ike ịsị na electrolyte bụ onye na-ebu maka mweghachi nke ion lithium n'etiti electrodes, na ịrụ ọrụ ya na-emetụta kpọmkwem oge nchaji na oge batrị.

II. Kedu ka Electrolytes si emetụta arụmọrụ ngwa ngwa batrị

Electrolyte bụ isi ihe dị na electrolyte ma na-arụ ọrụ dị mkpa na ịrụ ọrụ ngwa ngwa nke batrị. Nke mbụ, ionic conductivity nke electrolyte na-emetụta ngwa ngwa ion lithium na electrolyte ozugbo. Electrolytes nwere nnukwu ionic conductivity nwere ike ime ka ion lithium na-aga ngwa ngwa n'etiti electrodes dị mma na nke na-adịghị mma, si otú ahụ na-ebelata oge nchaji. Dịka ọmụmaatụ, ụfọdụ electrolytes ọhụrụ nwere ngagharị ionic dị elu ma nwee ike ịnye ọwa njem ion dị mma karịa n'oge chaja ngwa ngwa.

Nke abuo, nkwụsi ike nke electrolyte dịkwa oke mkpa maka ịrụ ọrụ ngwa ngwa ngwa ngwa. N'oge ịchaji ngwa ngwa, a ga-emepụta okpomọkụ na voltaji dị elu n'ime batrị. Ọ bụrụ na electrolyte anaghị akwụsi ike, ire ere ma ọ bụ mmeghachi omume akụkụ nwere ike ime, na-emetụta arụmọrụ na ndụ batrị. Ya mere, ịhọrọ electrolyte nwere ezigbo nkwụsi ike dị mkpa maka ịnweta chaja ngwa ngwa.

III. Ihe ndị na-emetụta arụmọrụ nchaji ngwa ngwa nke Electrolyte

Ụdị ihe mgbaze
Ka ọ dị ugbu a, ihe mgbaze electrolyte ndị a na-ejikarị gụnyere carbonates na carboxylates nwere yinye na usoro cyclic. Ebe mgbaze na viscosity nke ihe mgbaze ndị a ga-emetụta ọsọ mgbasa nke ion lithium. Na-ebelata ebe mgbaze na viscosity nke ihe mgbaze na ụlọ okpomọkụ, na-esiwanye ike ionic conductivity na elu nke mgbasa ozi onwe nke ion lithium, si otú ahụ na-eme ka ngwa ngwa odori arụmọrụ nke batrị.
Dịka ọmụmaatụ, ụfọdụ ihe mgbaze ndị nwere obere mgbaze na obere viscosity nwere ike inye ọwa mbugharị dị nro maka ion lithium, dị ka okporo ụzọ sara mbara ma dị larịị n'ime obodo, na-ekwe ka ụgbọ ala (lithium ions) mee njem ngwa ngwa.
Ịta n'ime electrolyte
Ịba ụba nke electrolyte nwere ike ịbawanye ọnụọgụ nke ion lithium nke onwe ya nke ukwuu. Nke a dị ka ịba ụba obosara nke ọwa ahụ, na-ekwe ka ion lithium gafere ngwa ngwa, si otú ahụ na-emeziwanye arụmọrụ ngwa ngwa nke batrị lithium-ion.
Were ya na mkpokọta electrolyte dị elu dị ka okporo ụzọ sara mbara nke nwere ike ịnabata ion lithium ka ọ gafere ngwa ngwa.
Nọmba mbugharị ion
Electrolytes nwere nnukwu ọnụọgụ ion migration nwere ike iguzogide ọnụego nchaji dị elu n'okpuru otu ọnọdụ nchaji. Nke a dị ka njikwa okporo ụzọ na-arụ ọrụ nke ọma karị iji hụ na ụgbọ ala na-agafe ngwa ngwa n'oge awa ọsọ.
Electrolytes nwere ọnụ ọgụgụ mbugharị ion dị elu nwere ike iduzi mbugharị nke ion lithium nke ọma ma melite arụmọrụ nchaji.
Ihe mgbaze na conductivity
The lithium ion conductivity na electrolytes nwere dị iche iche ihe mgbaze formulations dịkwa iche iche, na ọ nwere dị iche iche mmetụta na ngwa ngwa odori arụmọrụ nke batrị.
Site n'ịkwalite usoro ihe mgbaze, enwere ike ịchọta nchikota kachasị mma maka mbugharị lithium ion iji melite conductivity ma nweta ọsọ ọsọ chaja.
Nkwụsi ike okirikiri ogologo oge
Ụfọdụ usoro electrolyte nwere ike imeziwanye nkwụsi ike okirikiri na ike ịwepu nke batrị ahụ, ma n'otu oge ahụ na-ebelata ihe ngosi lithium plating na electrode na-adịghị mma nke batrị ahụ, na-emewanyewanye arụmọrụ ngwa ngwa.
Dị nnọọ ka inye batrị ahụ arụ ọrụ kwụsiri ike, hụ na ion lithium nwere ike ịkwaga nke ọma mgbe niile n'oge eji ogologo oge.

IV. Otu esi emeziwanye arụmọrụ elektrọnik

Iji meziwanye conductivity nke electrolyte, enwere ike ịmalite akụkụ ndị a:

Welie nhọrọ electrolyte: Họrọ electrolytes nwere nnukwu ionic conductivity, dị ka ụfọdụ nnu lithium ọhụrụ ma ọ bụ sistemu electrolyte agwakọta. Ndị a electrolytes nwere ike inyekwu ion n'efu ma kwalite ikike mbufe ion.
Gbanwee ihe mgbaze: Site n'ịkwalite ụdị na oke nke ihe mgbaze, belata viscosity nke electrolyte ma bulie ọsọ mgbasa ion. Dịka ọmụmaatụ, iji ihe mgbaze dị ala ma ọ bụ usoro ihe mgbaze agwakọta nwere ike imeziwanye conductivity nke electrolyte.
Ngwa nke mgbakwunye: Ịtinye ihe mgbakwunye kwesịrị ekwesị nke ihe mgbakwunye nwere ike imeziwanye conductivity nke electrolyte. Ihe mgbakwunye ndị a nwere ike ịbawanye ọnụ ọgụgụ ion migration ma melite arụmọrụ interface n'etiti electrode na electrolyte, si otú ahụ na-eme ka arụmọrụ ngwa ngwa nke batrị dịkwuo mma.
Njikwa okpomọkụ: N'ime ebe ụfọdụ, ịba ụba batrị na-arụ ọrụ nwere ike ibelata viscosity nke electrolyte ma mee ka ionic conductivity. Otú ọ dị, oke okpomọkụ nwere ike imetụta nkwụsi ike na ndụ batrị, ya mere ọ dị mkpa ijikwa ya n'ime oke okpomọkụ kwesịrị ekwesị.

V. Mpụtara nke nrụpụta arụmọrụ Electrolyte

Site na imeziwanye ụdị ihe mgbaze, ịhazigharị mkpokọta electrolyte, ịba ụba ọnụọgụ ion migration, na ịkwalite nhazi ihe mgbaze, enwere ike ịbawanye ọsọ nke lithium ion na electrolyte nke ọma, si otú a na-ebelata oge ịchaji. Nke a ọ bụghị naanị na-eme ka ahụmịhe onye ọrụ nke ndị na-azụ ahịa dịkwuo mma, na-enye ohere dị mma na ịchaji ahụmịhe maka njem dị anya nke ụgbọ ala eletrik, kamakwa na-akwalite mmepe nke ụlọ ọrụ ụgbọ ala ọhụrụ.

N'ọdịnihu, na-aga n'ihu na nkà na ụzụ na-aga n'ihu, a kwenyere na a ga-emeziwanye arụmọrụ nke electrolyte, na-eweta ike dị ike karị na ụzọ eji eme ihe na-adaba adaba na ụgbọ ala ike ọhụrụ. Ka anyị na-atụ anya ọganihu ọhụrụ na ngwa ngwa ngwa ngwa ngwa ngwa nke ụgbọ ala ike ọhụrụ ma na-enye aka na ọdịnihu nke njem ndụ ndụ ndụ.
