Babban darajar CMC

Carboxymethyl cellulose na baturi (CMC) wani nau'in CMC ne na musamman wanda ake amfani dashi azaman mai ɗaure da mai kauri a masana'antar batirin lithium-ion (LIBs). LIBs batir ne masu caji da aka saba amfani da su a cikin na'urorin lantarki masu ɗaukar nauyi, motocin lantarki, da tsarin ajiyar makamashi saboda yawan kuzarinsu da tsawon rayuwarsu. CMC-jin baturi yana taka muhimmiyar rawa a cikin tsarin ƙirƙira na'urar lantarki na LIBs, musamman a cikin samar da na'urorin lantarki don duka cathode da anode.

Ayyuka da Kaddarorin CMC na Batir:

1. Mai ɗaure: CMC-jin baturi yana aiki azaman ɗaure wanda ke taimakawa riƙe kayan aikin lantarki (kamar lithium cobalt oxide don cathodes da graphite don anodes) tare kuma manne su zuwa madaidaicin mai tarawa na yanzu (yawanci foil na aluminum don cathodes da foil jan ƙarfe don anodes). ). Wannan yana tabbatar da ingancin wutar lantarki mai kyau da kwanciyar hankali na injin lantarki.
2. Wakilin Kauri: CMC-jin baturi kuma yana aiki azaman wakili mai kauri a cikin ƙirar slurry na lantarki. Yana taimakawa sarrafa danko da kaddarorin rheological na slurry, yana ba da izinin sutura iri ɗaya da saka kayan lantarki akan mai tarawa na yanzu. Wannan yana tabbatar da daidaiton kauri da yawa, waɗanda ke da mahimmanci don samun ingantaccen aikin baturi.
3. Ionic Conductivity: CMC-jin baturi na iya zama na musamman gyaggyarawa ko ƙira don haɓaka haɓakar ion ɗin sa a cikin batirin lantarki. Wannan zai iya haɓaka aikin aikin sinadarai na lantarki gaba ɗaya da ingancin batirin lithium-ion.
4. Ƙarfafawa na Electrochemical: CMC-aji baturi an ƙera shi don kiyaye amincin tsarin sa da kwanciyar hankali na lantarki a tsawon rayuwar baturin, ko da a ƙarƙashin yanayin aiki mai tsanani kamar yanayin zafi da hawan keke. Wannan yana tabbatar da dogaro na dogon lokaci da amincin baturin.

Tsarin sarrafawa:

CMC-jin baturi yawanci ana samarwa ta hanyar gyare-gyaren sinadarai na cellulose, polysaccharide na halitta wanda aka samu daga filayen shuka. An gabatar da ƙungiyoyin carboxymethyl (-CH2COOH) akan kashin bayan cellulose ta hanyar jerin halayen sinadarai, wanda ya haifar da samuwar carboxymethyl cellulose. Matsayin maye gurbin carboxymethyl da nauyin kwayoyin halitta na CMC ana iya keɓance su don biyan takamaiman buƙatun aikace-aikacen baturi na lithium-ion.

Aikace-aikace:

CMC-jin baturi da farko ana amfani da shi wajen ƙirƙira na'urorin lantarki don batir lithium-ion, gami da daidaitawar silinda da jaka. An haɗa shi a cikin tsarin slurry na lantarki tare da sauran abubuwan da aka gyara kamar kayan lantarki masu aiki, abubuwan haɓakawa, da kaushi. Ana lulluɓe slurry ɗin lantarki akan abin da ake tarawa na yanzu, a bushe, a haɗa shi cikin tantanin baturi na ƙarshe.

Amfani:

1. Inganta Ayyukan Electrode: Matsayin baturi CMC yana taimakawa haɓaka aikin lantarki na lantarki, kwanciyar hankali na keke, da ƙarfin ƙimar batirin lithium-ion ta hanyar tabbatar da rufin lantarki iri ɗaya da mannewa mai ƙarfi tsakanin kayan aiki da masu tarawa na yanzu.
2. Ingantattun Tsaro da Amincewa: Yin amfani da babban darajar baturi CMC tare da kaddarorin da aka kera suna ba da gudummawa ga aminci, amintacce, da tsawon rayuwar batir lithium-ion, rage haɗarin delamination na lantarki, gajeriyar kewayawa, da abubuwan da suka faru na thermal runaway.
3. Ƙirar da aka keɓance: Za a iya keɓance ƙirar CMC-jin baturi don biyan takamaiman buƙatu da maƙasudin aiki na nau'ikan sinadarai na baturi, aikace-aikace, da tsarin masana'antu.

A taƙaice, carboxymethyl cellulose mai darajar baturi (CMC) wani abu ne na musamman wanda ke taka muhimmiyar rawa wajen samar da manyan batura na lithium-ion. Kayayyakinsa na musamman a matsayin mai ɗaure da kauri yana ba da gudummawa ga kwanciyar hankali, inganci, da amincin lantarki na batir lithium-ion, yana ba da damar haɓaka fasahar makamashi mai tsabta da motsin lantarki.
