Kedu otu esi edozi batrị lithium ion ultra-obere okpomọkụ nke nwere ike ịrụ ọrụ na-adịkarị na mwepu 60°C?

Na nso nso a, Ding Jianning nke Jiangsu University na ndị ọzọ na-eji lithium iron phosphate ntekwasa mesoporous carbon dị ka a nti electrode ihe na a siri ike carbon ihe onwunwe ọgaranya mesoporous Ọdịdị kwadebere site electrospinning technology dị ka a ọjọọ electrode ihe. Lithium bistrifluoromethanesulfonimide LiTFSi nnu na electrolyte nke DIOX (1,3-dioxane) + EC (ethylene carbonate) + VC (vinylidene carbonate) ihe mgbaze na-agbakọta n'ime batrị lithium-ion. Ihe batrị nke batrị nke ihe mepụtara nwere àgwà nnyefe ion magburu onwe ya na njirimara nkwụsị ngwa ngwa nke ion lithium, yana electrolyte dị ala nke na-arụ ọrụ nke ọma na obere okpomọkụ, na-eme ka batrị ahụ ka na-arụ ọrụ nke ọma na mwepu 60 °. C.

Dị ka nkà na ụzụ na-emepe emepe ngwa ngwa na ụlọ ọrụ batrị, ọha na eze na-anabata batrị lithium-ion maka nnukwu voltaji na-arụ ọrụ, njupụta ike dị elu, ogologo ndụ ogologo ndụ, nkwụsị nke onwe ya dị ala, enweghị mmetụta nchekwa, yana nchebe gburugburu ebe obibi "green". Ụlọ ọrụ ahụ etinyekwala ọtụtụ nyocha. A na-enwekwu nyocha na ion lithium nke nwere ike ime mgbanwe na okpomọkụ dị ala. Otú ọ dị, n'okpuru ọnọdụ okpomọkụ dị ala, viscosity nke electrolyte ga-abawanye nke ọma, ọ ga-agbatịkwa mmegharị nke batrị lithium-ion n'etiti ihe electrode. Na mgbakwunye, electrolyte ga-adị mma na obere okpomọkụ. Okpokoro SEI nke etolite na electrode na-adịghị mma ga-enwe mgbanwe mgbanwe na-agbanwe agbanwe wee ghọọ nke na-adịghị akwụsi ike. Ya mere, ihe electrode dị mma na nke na-adịghị mma na nke dị ugbu a na-enye ebe nhazi SEI kwụsiri ike karị, nkwụsị nnyefe dị mkpụmkpụ, na electrolyte nwere viscosity dị ala na obere okpomọkụ, na-aghọta batrị lithium nke ka nwere ike ịrụ ọrụ na okpomọkụ dị ala. nke na-erughị 60 Celsius C. . Nsogbu teknuzu nke a ga-edozi site na mmepụta ihe bụ imeri njedebe nke ngwa ngwa nke ihe batrị lithium na gburugburu ebe okpomọkụ dị ala na nsogbu nke viscosity dị elu nke electrolytes ndị a na-emekarị na obere okpomọkụ na obere ion na-agagharị agagharị, ma na-enye ụgwọ ọrụ dị elu. na ịgbasa na ultra-obere okpomọkụ Batrị lithium-ion na usoro nkwadebe ya na-eji batrị lithium-ion iji nweta ezigbo ụgwọ na mwepu arụmọrụ na obere okpomọkụ.

Ọgụgụ 1 Ntụle nke electrochemical arụmọrụ nke batrị lithium-ion dị obere okpomọkụ na ụlọ okpomọkụ na obere okpomọkụ.

Mmetụta bara uru nke ihe mepụtara bụ na mgbe a na-eji ihe electrode na-emerụ ahụ mee ihe dị ka mpempe akwụkwọ electrode, ọ dịghị ihe nkedo achọrọ. Ọ gaghị ebelata conductivity, ọ ga-eme ka ọnụ ọgụgụ nke arụmọrụ dịkwuo elu.

Mgbakwunye: ozi patent

Aha patent: Usoro nkwadebe nke ultra-low okpomọkụ batrị lithium-ion nwere ike na-arụ ọrụ na mwepu 60°C
