Codsiga CMC Binder ee baytariyada

Dhinaca tignoolajiyada batteriga, doorashada shay-xidhaha ayaa door muhiim ah ka ciyaara go'aaminta waxqabadka, xasiloonida, iyo cimriga batteriga.Carboxymethyl cellulose (CMC), polymer-ka biyaha-milmi kara oo ka soo jeeda cellulose, ayaa u soo baxday sidii xidhitaan rajo leh sababtoo ah sifooyinkeeda gaarka ah sida xoogga sare ee adhesion, awoodda samaynta filimada wanaagsan, iyo waafaqsanaanta deegaanka.

Baahida sii kordheysa ee baytariyada waxqabadka sare leh ee warshadaha kala duwan, oo ay ku jiraan baabuurta, elektiroonigga, iyo tamarta la cusboonaysiin karo, ayaa kicisay dadaallo cilmi baaris oo ballaaran si loo horumariyo agabka baytariyada cusub iyo teknoolajiyada. Qaybaha muhiimka ah ee batteriga, xidhuhu waxa uu door muhiim ah ka ciyaaraa dhaqaajinta agabka firfircoon ee ururiyaha hadda jira, isaga oo hubinaya lacag-bixin hufan iyo wareegyo dareere ah. Xirayaasha dhaqameed sida fluoride polyvinylidene (PVDF) waxay leeyihiin xaddidaadyo xagga saamaynta deegaanka, sifooyinka farsamada, iyo la jaanqaadida kimistariga soo socda ee baytariyada. Carboxymethyl cellulose (CMC), oo leh sifooyinkeeda gaarka ah, ayaa u soo baxay wax rajo ah oo beddelka ah oo lagu hagaajinayo waxqabadka batteriga iyo waaritaanka.

1.Qaabka Carboxymethyl Cellulose (CMC):
CMC waa soosaar biyo-milmi leh oo ah cellulose, polymer dabiici ah oo ku badan derbiyada unugyada dhirta. Iyada oo loo marayo wax ka beddelka kiimikaad, kooxaha karboxymethyl (-CH2COOH) ayaa lagu soo bandhigaa laf dhabarta cellulose, taasoo keentay in la wanaajiyo milanka iyo hagaajinta sifooyinka shaqada. Qaar ka mid ah sifooyinka muhiimka ah ee CMC ee khuseeya codsigeeda

(1) baytariyada waxaa ka mid ah:

Awoodda adhession ee sare: CMC waxay soo bandhigaysaa sifooyin adag oo xabag ah, taas oo awood u siinaysa inay si wax ku ool ah ugu xidho walxaha firfircoon dusha sare ee ururiyaha hadda, taas oo hagaajinaysa xasilloonida korantada.
Awoodda samaynta filimada ee wanaagsan: CMC waxay samayn kartaa labbis iyo filimaan cufan oo ku yaal dusha sare ee korantada, fududaynta korantada walxaha firfircoon iyo kor u qaadida isdhexgalka electrode-electrolyte.
Waafaqsanaanta deegaanka: Sida polymer-ka noolaha ah iyo kuwa aan sunta ahayn ee laga keenay ilo dib loo cusboonaysiin karo, CMC waxay bixisaa faa'iidooyinka deegaanka marka loo eego xirmooyinka synthetic sida PVDF.

2.Codsiga CMC Binder ee baytariyada:

(1) Farsamaynta Korantada:

CMC waxaa caadi ahaan loo isticmaalaa sidii xire ahaan soo saarista electrodes ee kiimikada baytariyada kala duwan, oo ay ku jiraan baytariyada lithium-ion (LIBs), baytariyada sodium-ion (SIBs), iyo supercapacitors.
Gudaha LIB-yada, CMC waxay hagaajisaa isku-xidhka walxaha firfircoon (tusaale, lithium cobalt oxide, graphite) iyo ururiyaha hadda (tusaale, bireed naxaas ah), taasoo horseedaysa hufnaanta korantada oo la xoojiyey iyo hoos u dhigista muddada baaskiilka.
Sidoo kale, gudaha SIB-yada, korantada-ku-saleysan CMC waxay muujisaa xasilloonida iyo waxqabadka baaskiilka oo soo hagaagay marka la barbar dhigo koronto-dhaliyeyaasha caadiga ah.
Awoodda filim samaynta eeCMCWaxay hubisaa daahan isku midka ah ee walxaha firfircoon ee ururiyaha hadda, yaraynta porosity electrode iyo hagaajinta kinetics gaadiidka ion.

(2) Kobcinta Anshaxa:

Inkasta oo CMC lafteedu aanay ahayn mid dhaqdhaqaajin leh, ku-dariddeeda qaab-dhismeedka korantada waxay kor u qaadi kartaa dhaqdhaqaaqa korantada guud ee korantada.
Xeeladaha ay ka midka yihiin ku-darka waxyaabaha lagu daro (tusaale, kaarboon-madow, graphene) oo ay weheliso CMC ayaa la adeegsaday si loo yareeyo carqaladaynta la xiriirta koronto-ku-saleysan CMC.
Nidaamyada isku-xidhka isku-dhafka ah ee isku-darka CMC iyo polymers-ka-qaadista ama kaarboon nanomaterials waxay muujiyeen natiijooyin rajo leh oo lagu hagaajinayo korantada korantada iyada oo aan la hurin sifooyinka farsamada.

3.Xasilloonida korantada iyo waxqabadka baaskiilka:

CMC waxa uu door muhiim ah ka ciyaaraa ilaalinta xasiloonida korantada iyo ka hortagga kala goynta walxaha firfircoon ama kacsanaanta inta lagu jiro baaskiil wadida.
Dabacsanaanta iyo ku dheggan adag ee ay bixiso CMC waxay gacan ka geysataa hufnaanta farsamada ee electrodes, gaar ahaan marka lagu jiro xaaladaha walaaca firfircoon inta lagu jiro wareegyada lacag-bixinta.
Dabeecadda hydrophilic ee CMC waxay ka caawisaa ku haysashada korantada gudaha qaab dhismeedka korantada, hubinta gaadiidka ion ee joogtada ah iyo yaraynta awoodda baskii baaskiilka daba dheeraatay.

4.Caqabadaha iyo Aragtiyada Mustaqbalka:

Iyadoo codsiga CMC binder ee baytariyadu ay bixiso faa'iidooyin la taaban karo, caqabado badan iyo fursado horumar ah

(1) waxaa jira:

Habdhaqan Wanaagsan: Cilmi-baaris dheeraad ah ayaa loo baahan yahay si kor loogu qaado dhaqdhaqaaqa korantada-ku-saleysan ee CMC, iyada oo loo marayo qaabab cusub oo isku xira ama isku-dhafan isku-dhafan oo lagu daro wax-qabad.
Waafaqsanaanta Che-Tamarta Sare

Mistries: Ka faa'iidaysiga CMC ee kiimikooyinka baytariyada soo baxaya ee leh cufnaanta tamarta sare, sida lithium-sulfur iyo baytariyada lithium-hawo, waxay u baahan tahay in si taxadar leh looga fiirsado xasilloonida iyo waxqabadka korantada.

(2) Isku-dheellitirnaan iyo wax-ku-oolnimo:
Wax-soo-saarka cabbirka-warshadaha ee koronto-ku-salaysan CMC waa inuu noqdaa mid dhaqaale ahaan shaqayn kara, oo lama huraan ah waddooyin isku-dhafan oo kharash-ku-ool ah iyo geeddi-socod wax-soo-saar la miisaami karo.

(3) Waaritaanka Deegaanka:
Iyadoo CMC ay bixiso faa'iidooyinka deegaanka marka loo eego xirmooyinka caadiga ah, dadaallada lagu wanaajinayo waaritaanka dheeraadka ah, sida ka faa'iidaysiga ilo-cellulose dib loo warshadeeyay ama soo saarista elektrolytka biodegradable, waa la dammaanad qaaday.

Carboxymethyl cellulose (CMC)waxay matalaysaa qalab isku xidhan oo waara oo leh karti aad u wayn oo lagu horumarinayo tignoolajiyada batteriga. Isku darka gaarka ah ee xoogga dhejiska, kartida samaynta filimada, iyo waafaqid deegaanka ayaa ka dhigaya doorasho soo jiidasho leh oo kor loogu qaado waxqabadka korantada iyo xasilloonida dhammaan noocyada kiimikada batteriga. Cilmi-baarista joogtada ah iyo dadaallada horumarinta ee loogu talagalay hagaajinta hababka korantada ee CMC-ku-salaysan, hagaajinta dhaqdhaqaaqa, iyo wax ka qabashada caqabadaha scalability waxay waddada u xaari doontaa qaadashada baahsan ee CMC ee baytariyada soo socda, taas oo gacan ka geysaneysa horumarinta tignoolajiyada tamarta nadiifka ah.
