Yadda ake shirya batirin lithium ion mai ƙarancin zafin jiki wanda zai iya aiki kullum a debe 60°C?

Kwanan nan, Ding Jianning na Jami'ar Jiangsu da sauransu sun yi amfani da lithium baƙin ƙarfe phosphate mai rufi mesoporous carbon a matsayin tabbatacce electrode abu da kuma wuya carbon abu mai arziki a cikin mesoporous tsarin tattalin electrospinning fasaha a matsayin korau electrode abu. Lithium bistrifluoromethanesulfonimide LiTFSi gishiri da electrolyte na DIOX (1,3-dioxane) + EC (ethylene carbonate) + VC (vinylidene carbonate) kaushi suna harhada a cikin wani lithium-ion baturi. Kayan baturi na baturi na ƙirƙira yana da kyawawan halayen watsa ion da kuma saurin lalacewa na lithium ions, da ƙananan zafin jiki na lantarki wanda ke kula da kyakkyawan aiki a ƙananan zafin jiki, yana tabbatar da cewa baturin zai iya aiki kullum a rage 60 °. C.

A matsayin fasaha mafi saurin haɓakawa a cikin masana'antar batir, jama'a suna maraba da batir lithium-ion don babban ƙarfin aiki, ƙarfin kuzari, tsawon rayuwa, ƙarancin fitar da kai, rashin tasirin ƙwaƙwalwa, da kare muhalli "kore". Har ila yau, masana'antar ta zuba jari mai yawa don bincike. Akwai ƙarin bincike akan ions lithium waɗanda zasu iya dacewa da yanayin zafi mara nauyi. Duk da haka, a ƙarƙashin ƙananan yanayin zafi, danko na electrolyte zai ƙaru sosai, kuma zai tsawaita motsi na baturan lithium-ion tsakanin kayan lantarki. Bugu da ƙari, electrolyte zai zama tabbatacce a ƙananan yanayin zafi. Layin SEI da aka kafa a cikin gurɓataccen lantarki zai fuskanci canjin lokaci kuma ya zama mafi rashin kwanciyar hankali. Saboda haka, tabbatacce da korau kayan lantarki a cikin na yanzu ƙirƙira samar da mafi barga SEI samuwar yanayi, da guntu watsa nisa, da wani electrolyte tare da ƙananan danko a low yanayin zafi, gane da lithium baturi wanda har yanzu iya aiki a wani matsananci-low zazzabi. kasa da 60 ° C. . Matsalar fasaha da za a warware ta hanyar ƙirƙira ita ce ta shawo kan iyakokin aikace-aikace na kayan baturi na lithium a cikin ƙananan yanayin zafi da kuma matsalar babban danko na electrolytes na al'ada a ƙananan zafin jiki da ƙananan motsi na ion, da kuma samar da caji mai girma. da fitarwa a ƙananan zafin jiki Batirin lithium-ion da tsarinsa suna amfani da baturin lithium-ion don samun kyakkyawan caji da aikin fitarwa a ƙananan yanayin zafi.

Hoto 1 Kwatanta aikin electrochemical na ƙananan batura lithium-ion masu zafi a dakin da zafin jiki da ƙananan zafin jiki.

Amfanin abin ƙirƙira shine lokacin da aka yi amfani da kayan lantarki mai cutarwa azaman takardar lantarki, ba a buƙatar ɗaure ba. Ba zai rage yawan aiki ba, kuma zai haɓaka ƙimar aiki.

Abin da aka makala: bayanin lamba

Sunan haƙƙin mallaka: Hanyar shiri na baturi lithium-ion mai ƙarancin zafin jiki wanda yawanci zai iya aiki a rage 60°C
