1. Isticmaal batari lithium ah oo ammaan ah oo hadda lithium electrolyte ah oo isticmaalaya carbonate sida dareere ah, halkaas oo kaarboonka tooska ah uu hagaajin karo kharashka iyo soo saarista awoodda batteriga, laakiin bartooda fiilada ayaa hooseeya, heerkulka hoose Wuu iftiimin doonaa, dareeraha fluoro caadi ahaan wuxuu leeyahay dhibic sare ama filaash la&39;aan, markaa dareeraha fluoro waxaa loo isticmaalaa in lagu xakameeyo gubashada electrolyte. Qallalka fluoride ee hadda la bartay waxaa ka mid ah fluoroate iyo fluoroethyl ether.

Electrolyte retardant ololku waa koronto shaqaynaysa taas oo shaqada dib-u-dhigista ololka ee elektrolytka noocan oo kale ah inta badan lagu helo iyada oo lagu daro wax lagu daro ololka ee elektrolytka caadiga ah. Electrolyt-ka ololka ayaa hadda xalinaya tallaabooyinka ugu dhaqaale iyo waxtarka badan ee badbaadada baytariga lithium, gaar ahaan ku xiran warshadaha. Isticmaalka electrolytes adag, halkii laga isticmaali lahaa electrolytes dareeraha organic, si wax ku ool ah u hagaajiyaan badbaadada baytariyada lithium.

Electrolytes adag waxaa ka mid ah electrolytes adag polymer iyo inorganic adag electrolytes. Electrolyt-ka polymer-ka, gaar ahaan nooca jel-ka-polymer-ka, ayaa si weyn loogu sameeyay baytariga lithium-ka ganacsiga, laakiin nooca jel-polymer-ka-ku-oolka ah ayaa dhab ahaantii ah electrolyte-ka polymer-ka-qalalan iyo dareeraha dareeraha ah ee dareeraha ah. Natiijo ahaan, aad bay u xaddidan tahay hagaajinta badbaadada batteriga.

Sababtoo ah elektrolytka polymerization-ka qalalan, maadaama aysan ahayn sida jel-nooca polymer electrolyte, waxay leedahay badbaado wanaagsan marka la eego daadinta, cadaadiska uumiga iyo gubasho. Waqtigan xaadirka ah, isku-darka korantada hadda ma buuxinayso shuruudaha codsiga ee baytariyada lithium-ka polymer, waxaana la filayaa in cilmi-baaris dheeraad ah loo isticmaalo baytariyada kaydinta lithium-ka polymer. Electrolyte-ka polymer-ka ee laxidhiidha, elektrolytka adag ee aan organic-ga ahayn ayaa leh badbaado kasii wanaagsan, wax isbedbeddela leh, gubasho la&39;aan, wax dhib ah oo ka sii daadanaya ma jirto.

Dheeraad ah, xoogga farsamada ee elektrolytka adag inorganic waa sarreeyaa, heerkulka kulaylka u adkaysta ayaa si weyn uga sarreeya kan dareeraha dareeraha ah iyo polymer organic, oo balaariyay heerkulka hawlgalka ee batteriga; walxaha aan organic waxaa lagu sameeyaa filim, taas oo ay u badan tahay in la gaaro miniaturization batari lithium ah, iyo nooca batari uu leeyahay nolosha kaydinta Ultra-dheer si weyn u ballaarin kara goobta codsiga ee baytariyada lithium jira. 2. Hagaajinta dhibaatada badbaadada heerkulbeegga walxaha korantada waxaa si toos ah u sababa korantada aan badbaado lahayn, laakiin laga bilaabo sababta asalka ah, sababtoo ah batteriga laftiisa ma aha mid sarreeya, dhacdada kuleylka ka baxsan xakamaynta ayaa keentay.

Marka lagu daro xasilloonida kuleylka ee elektrolytka, xasiloonida kulaylka ee electrolyte sidoo kale waa mid ka mid ah sababaha ugu muhiimsan, sidaas darteed xasiloonida kulaylka ee qalabka korantada ayaa sidoo kale ah qayb muhiim ah oo ka mid ah hagaajinta badbaadada batteriga, laakiin korantada halkan lagu xusay Dejinta kuleylka alaabta waxaa ka mid ah ma aha oo kaliya xasilloonida kulaylka ee qalabka elektaroonigga ah. Caadi ahaan, xasiloonida kulaylka ee walxaha korantada taban waxaa lagu go&39;aamiyaa dhaqdhaqaaqa qaab dhismeedka maaddada iyo ku dallaca elektiroonigga taban. Marka la eego walxaha kaarboonka, walxaha kaarboonka wareegsan, sida dhexdhexaadiyaha kaarboonka dhexdhexaadka ah (MCMB), oo leh saami hoose, lacag sare iyo madal dheecaan ah, markaa xaaladeeda dallacadu way yar tahay, xasiloonida kulaylkuna waa la barbardhigay.

Wanaagsan, ammaan sare. Li4Ti5O12 ee qaab-dhismeedka laf-dhabarta ayaa ka wanaagsan xasilloonida qaab-dhismeedka garaafka la-saaray, iyo khidmadda iyo madal-soo-saarka ayaa aad uga sarreeya, markaa xasilloonida kulaylku way ka fiican tahay ammaankuna wuu sarreeyaa. Sidaa darteed, MCMB ama Li4Ti5o12 waxaa sida caadiga ah loo isticmaalaa batari korantada lithium-ion ee shuruudaha badbaadada si loogu beddelo garaafka caadiga ah sida korantada taban.

Marka lagu daro maaddada lafteeda, xasiloonida kulaylka ee walxaha korantada taban ayaa aad uga walaacsan xasiloonida kulaylka ee xuubka elektrolytka adag (SEI) ee dhexdhexaadiyaha korantada xun ee dhexdhexaadiyaha elektaroonigga ah, kaas oo inta badan loo isticmaalo qalab isku mid ah, gaar ahaan graphite. Ka fakar in ay tahay tillaabada ugu horreysa ee dhacdada luminta kulaylka. Waxaa jira laba siyaabood oo muhiim ah oo lagu hagaajinayo xasiloonida kulaylka ee filimka SEI: mid waa dahaarka dusha sare ee walxaha korantada xun, sida daboolka dhuxusha amorphous ama lakabka birta ee dusha sare ee garaafka; Midda kale waa in lagu daro waxyaabaha lagu daro filim samaynta ee elektrolytka, ee batteriga Inta lagu jiro habka firfircoonida, waxay sameeyaan filim SEI oo leh xasiloonida walxaha korantada, taas oo faa&39;iido u leh helitaanka xasilloonida kulaylka wanaagsan.
