Sida loo hagaajiyo badbaadada baytariyada lithium

Faa'iidada baabuurta tamarta cusub waa in ay ka badan yihiin kaarboon-yar oo deegaan ahaan ka wanaagsan baabuurta shidaalka ku shaqeeya. Waxay isticmaashaa shidaalka baabuurta aan caadiga ahayn sida isha tamarta, sida baytariyada lithium, shidaalka hydrogen, iwm. Codsiga baytari lithium-ion sidoo kale waa mid aad u ballaaran, ka sokow baabuurta tamarta cusub, telefoonada gacanta, laptops, PC tablets, korontada gacanta, baaskiilada korontada , Qalabka korontada, iwm.

Si kastaba ha ahaatee, badbaadada baytariyada lithium-ion waa in aan la dhayalsan. Shilal dhowr ah ayaa muujinaya in marka dadku ay si khaldan u dallacaan, ama heerkulka jawigu aad u sarreeyo, ay aad u sahlan tahay in ay kiciyaan baytariyada lithium-ion gubasho kedis ah, qarax, taas oo noqotay meesha ugu xanuunka badan ee horumarinta baytariyada lithium-ion.

In kasta oo sifooyinka baytariga lithium laftiisa ay go'aamiyaan qaddarkiisa "holci kara iyo kuwa qarxa", laakiin gabi ahaanba ma aha wax aan macquul ahayn in la yareeyo khatarta iyo badbaadada. Horumarka joogtada ah ee tignoolajiyada batteriga, labadaba shirkadaha taleefanka gacanta iyo shirkadaha cusub ee baabuurta tamarta, iyada oo loo marayo nidaamka maaraynta batteriga macquulka ah iyo nidaamka maaraynta kulaylka, batteriga wuxuu awoodi doonaa inuu hubiyo badbaadada, mana qarxi doono ama ifafaale gubasho lama filaan ah.

1.Hagaajinta badbaadada elektrolytka

Waxaa jira falcelis sare oo udhaxeeya elektrolytka iyo electrodes-ka togan iyo kuwa taban, gaar ahaan heerkul sare. Si loo hagaajiyo badbaadada baytariyada, hagaajinta badbaadada elektrolytka waa mid ka mid ah hababka waxtarka leh. Marka lagu daro waxyaabaha lagu daro, isticmaalka cusbada lithium-ka cusub iyo isticmaalka dareerayaasha cusub, khataraha badbaadada elektrolytka ayaa si wax ku ool ah loo xalin karaa.

Sida laga soo xigtay hawlaha kala duwan ee daroogooyinka, waxaa loo qaybin karaa qaybaha soo socda: daroogooyinka ilaalinta badbaadada, wax-ku-dhafka filimada-samaynta, daroogooyinka ilaalinta cathode, wax-qabadyada xasilinta milixda lithium, daroogooyinka dhiirrigelinta roobabka lithium-ka, wax-soo-saarka dareeraha-ka-hortagga-ka-hortagga, wax-qabadyada qoyaanka oo la xoojiyay. iwm.

2. Hagaajinta badbaadada qalabka korantada

Fosfooraska birta ee Lithium iyo isku-dhafka ternary waxaa loo tixgeliyaa inay yihiin qiime jaban, "nabadgelyo aad u wanaagsan" agab cathode oo awood u leh in si caan ah loogu isticmaalo warshadaha gawaarida korontada. Maaddada cathode, habka caadiga ah ee lagu hagaajinayo badbaadadiisa waa wax ka beddelka daahan, sida oksijiinta birta ee dusha sare ee walxaha cathode, waxay ka hortagi kartaa xiriirka tooska ah ee u dhexeeya walxaha cathode iyo electrolyte, waxay joojinayaan isbeddelka walxaha cathode isbeddelka, hagaajinta qaabdhismeedkeeda. xasilloonida, yarayso khalkhalka cations ee shabagga, si loo yareeyo wax soo saarka kulaylka falcelinta dhinaca.

Qalabka elektaroonigga ah ee taban, maadaama ay dusha sare inta badan tahay qayb ka mid ah baytariyada lithium-ion ee ugu nugul burburka thermochemical iyo exotherm, hagaajinta xasilloonida kuleylka ee filimka SEI waa hab muhiim ah oo lagu hagaajinayo badbaadada qalabka elektaroonigga ah. Xasiloonida kulaylka ee alaabta anode waxaa lagu wanaajin karaa oksaydhka daciifka ah, dhigista birta iyo oksaydhka birta, polymer ama daboolka kaarboonka.

3. Hagaajinta nashqada ilaalinta badbaadada batteriga

Marka lagu daro hagaajinta badbaadada alaabta batteriga, tallaabooyin badan oo ilaalinta badbaadada ee loo isticmaalo baytariyada lithium-ion ganacsi, sida dejinta batteriga badbaadada, fiyuusyada kulaylka leh, isku xirka qaybaha leh heerkulbeegyo togan oo taxane ah, iyadoo la adeegsanayo diaphragms kuleyl leh, raraya ilaalin gaar ah. wareegyada, iyo hababka maaraynta baytariyada u go'an, ayaa sidoo kale macnaheedu yahay in kor loogu qaado badbaadada.
