1. Yi amfani da amintaccen baturi na lithium electrolyte a halin yanzu lithium baturi electrolyte ta yin amfani da carbonate a matsayin kaushi, inda carbonate linear zai iya inganta caji da fitarwa damar baturi, amma su flash batu ne low, a ƙananan zafin jiki Zai yi haske, kuma fluoro sauran ƙarfi yawanci yana da mafi girma filasha batu ko babu filasha, don haka fluoro sauran ƙarfi da ake amfani da su kashe konewar electrolyte. Abubuwan kaushi na fluoride da aka yi nazari a halin yanzu sun haɗa da fluoroate da fluoroethyl ether.

Flame retardant electrolyte shine lantarki mai aiki wanda yawancin wutar lantarki na irin waɗannan electrolytes ana samun su ta hanyar ƙara ƙarar wuta a cikin lantarki na al&39;ada. Wutar lantarki mai hana wuta a halin yanzu tana warware mafi girman matakan tattalin arziki da inganci don amincin baturin lithium, musamman dangane da masana&39;antar. Yin amfani da daskararrun electrolytes, maimakon Organic ruwa electrolytes, yadda ya kamata inganta amincin batura lithium.

M electrolytes sun hada da polymer m electrolytes da inorganic m electrolytes. Polymer electrolyte, musamman nau&39;in nau&39;in polymer electrolyte, an yi shi sosai a cikin baturin lithium na kasuwanci, amma nau&39;in gel-nau&39;in polymer electrolyte shine ainihin busasshen polymer electrolyte da ruwa mai daidaitawa. Sakamakon haka, yana da iyaka sosai a cikin haɓaka amincin baturi.

Saboda electrolyte na bushe-bushe polymerization, tun da yake ba kamar gel-type polymer electrolyte, yana da mafi aminci dangane da yayyo, tururi matsa lamba da kuma konewa. A halin yanzu, jimlar electrolyte na yanzu bai cika buƙatun aikace-aikacen baturin lithium na polymer ba, kuma ana sa ran za a yi amfani da ƙarin bincike a ko&39;ina a cikin batura na lithium na polymer. polymer electrolyte da ke da alaƙa da lokaci, inorganic m electrolyte yana da ingantaccen aminci, babu jujjuyawa, babu konewa, ƙari babu matsalar ɗigo.

Bugu da ari, da inji ƙarfi na inorganic m electrolyte ne high, zafi-resistant zafin jiki ne muhimmanci mafi girma fiye da na ruwa electrolyte da wani Organic polymer, kara girman aiki zafin jiki kewayon baturi; Ana yin kayan da ba a haɗa su ba zuwa fim, wanda zai fi dacewa don cimma ƙarancin batirin lithium, kuma irin wannan baturi yana da rayuwar adanawa ta Ultra-long na iya faɗaɗa filin aikace-aikacen batirin lithium da ke akwai. 2. Inganta matsalar tsaro na thermosability na kayan lantarki yana haifar da kai tsaye ta hanyar rashin lafiyan electrolyte, amma daga tushen dalilin, saboda baturin da kansa ba shi da girma, abin da ya faru na thermal daga sarrafawa ya haifar.

Bugu da ƙari, kwanciyar hankali na thermal na electrolyte, kwanciyar hankali na thermal na electrolyte shi ma yana daya daga cikin muhimman dalilai, ta yadda yanayin zafi na kayan lantarki ya zama muhimmin bangare na inganta lafiyar baturi, amma wutar lantarki da aka ambata a nan. Yawancin lokaci, kwanciyar hankali na thermal na abu mara kyau yana ƙayyade ta aikin tsarin kayan aiki da kuma caji mara kyau na lantarki. Game da kayan carbon, kayan carbon mai siffa, kamar matsakaicin microspheres na carbon (MCMB), tare da ƙaramin rabo, caji mafi girma da dandamali na fitarwa, don haka yanayin cajin sa ya yi ƙarami, kuma kwanciyar hankali na thermal yana da ɗan kwatanta.

Kyakkyawan, babban tsaro. Li4Ti5O12 na tsarin spinel yana da kyau fiye da tsarin kwanciyar hankali na laminated graphite, kuma cajin da dandamali ya fi girma, don haka kwanciyar hankali na thermal ya fi kyau kuma aminci ya fi girma. Saboda haka, MCMB ko Li4Ti5o12 yawanci ana amfani dashi a cikin baturin lithium-ion na buƙatun aminci don maye gurbin graphite na yau da kullun azaman na&39;urar lantarki mara kyau.

Bugu da ƙari, da kayan da kanta, da thermal kwanciyar hankali na korau electrode abu ya fi damuwa game da thermal kwanciyar hankali na m electrolyte membrane (SEI) na korau electrolyte dubawa na electrolyte dubawa, wanda sau da yawa amfani da wannan abu, musamman graphite. Yi tunanin cewa shine mataki na farko a cikin abin da ya faru na asarar zafi. Akwai hanyoyi guda biyu masu mahimmanci don inganta kwanciyar hankali na thermal na fim din SEI: daya shine rufin farfajiya na kayan lantarki mara kyau, kamar suturar gawayi mai amorphous ko karfe Layer a saman graphite; da sauran shi ne don ƙara fim forming Additives a cikin electrolyte, a cikin baturi A lokacin kunnawa tsari, sun samar da wani SEI fim da samun kwanciyar hankali na lantarki abu, wanda shi ne m ga samun mafi kyau thermal kwanciyar hankali.
