Gusaba CMC Binder muri bateri

Nkibintu nyamukuru bihuza ibikoresho bibi byamazi, ibicuruzwa bya CMC bikoreshwa cyane nabakora bateri yo murugo ndetse no mumahanga. Umubare mwiza wa binder urashobora kubona ubushobozi bunini bwa bateri, ubuzima burebure kandi ugereranije nimbere imbere.

Binder ni kimwe mu bikoresho byingenzi bikora muri lithium-ion ion batteri. Ninkomoko nyamukuru yimiterere ya electrode yose kandi ifite ingaruka zikomeye kumikorere ya electrode na electrochemical imikorere ya bateri. Binder ubwayo nta bushobozi ifite kandi ifite uruhare runini cyane muri bateri.

Usibye imitungo ifatika ya rubanda, Lithium-bateri ya electrode binder ibikoresho kandi bigomba gushobora kwihanganira kubyimba no kugambana kwa electrolyte, ndetse no guhangana na electrochemique mugihe cyo kwishyuza no gusohoka. Iguma mu ntera ya voltage yakazi, ntabwo rero hariho ibikoresho byinshi bya polymer bishobora gukoreshwa nka electrode bihuza batteri ya lithium-ion.

Hariho ubwoko butatu bwingenzi bwa lithium-ion bunders byakoreshwa cyane muri iki gihe: PVDF), StyVIYLDEDEN (PVDF), Stry Byongeye kandi, aside ya polyacryct (paa), imiyoboro ishingiye ku mazi hamwe na polyacrylonike (isafuriya) na polyacrylate nk'ibice by'ingenzi birimo isoko runaka.

Ibiranga bine bya bateri-urwego CMC

Kubera ibibazo bikennye byamazi yuburyo bwa acide ya acide ya carboxymethyl selile selile, kugirango mpikorere kubishyira mubikorwa neza, CMC ni ibintu bikoreshwa cyane muri bateri.

Nkibintu nyamukuru bihuza ibikoresho bibi byamazi, ibicuruzwa bya CMC bikoreshwa cyane nabakora bateri yo murugo ndetse no mumahanga. Umubare mwiza wa binder urashobora kubona ubushobozi bunini bwa bateri, ubuzima burebure kandi ugereranije nimbere imbere.

Ibiranga ine muri CMC ni:

Ubwa mbere, CMC irashobora gukora ibicuruzwa hydrophilic no gushonga, gushonga rwose mumazi, nta fibre nubuntu.

Icya kabiri, urwego rwo gusimburwa ni imyenda kandi visosity irahamye, ishobora gutanga vicositine ihamye no kumeneka.

Icya gatatu, kubyara ibicuruzwa bisukuye birekura hamwe nicyuma kito.

Icya kane, ibicuruzwa bifite ubusobanuro bwiza na SBR ya latex nibindi bikoresho.

CMC Sodium Carboxymethyl Velilese yakoreshejwe muri bateri yemeje ingaruka zayo, kandi mugihe kimwe zitanga imikorere myiza, hamwe ningaruka zikoreshwa.

Uruhare rwa CMC muri bateri

CMC ni carboxymethyly bakomoka kuri selile, ubusanzwe biterwa no gufata selile karemano hamwe na aside ya monochlorocetique na monochlolorondoaceti na monochlolorondoaceti, nuburemere bwayo bwa molekile bugabanyijemo ibihumbi.

CMC niyera ifu yumuhondo yoroheje, granular cyangwa fibrous ikintu, gifite hygroscopity kandi byoroshye mumazi. Iyo bitagira aho babogamiye cyangwa alkaline, igisubizo ni amazi menshi. Niba yashyutswe hejuru ya 80 ℃ igihe kirekire, vino izagabanuka kandi izahuzwa mumazi. Ihindura brown mugihe ashyushye kugeza 190-205 ° C, na karubone iyo ashyushye kugeza 235-248 ° C.

Kubera ko CMC ifite imirimo yo kwinubira, guhuza, kugumana amazi, guhindagurika no guhagarikwa no gusiganwa, imiti, imiti, imiti, imiti, imiti, ibishushanyo, bizwi cyane kuri "monosodium yinganda glutamate ".

By'umwihariko muri bateri, imikorere ya CMC ni: Gukwirakwiza amatora mato ya electrode ibikoresho bifatika kandi bifata neza; Ingaruka na kurwanya etactimenttion kuri electrode mbi; Gufasha Guhuza; Guhagarika imikorere yo gutunganya bya electrode no gufasha kunoza imikorere ya bateri; Kunoza imbaraga za Peel igice, nibindi

Imikorere ya CMC no guhitamo

Ongeraho CMC mugihe uhindagurika electrode birashobora kongera viscolity yo gutandukana no gukumira ibitonyanga gutura. CMC izatanga sodium ions na anone mu gisubizo cy'amazi, kandi visosi ya kolee izagabanuka no kwiyongera k'ubushyuhe, biroroshye gukuramo ubushuhe kandi biroroshye cyane.

CMC irashobora kugira uruhare rwiza cyane mugutatanya ibishushanyo mbonera bya electrode. Mugihe umubare wa CMC wiyongera, ibicuruzwa byayo byo kuboneza bizakurikiza hejuru yibishushanyo, kandi ibishushanyo mbonera bizavanga kubera imbaraga za electrostatic, kugera kubintu byiza.

Ibibi bigaragara bya CMC nibyo bikaboroga. Niba CMC yose ikoreshwa nka binder, igishushanyo kibi cya electrode izasenyuka mugihe cyo gukanda no gukata igice cya pole, kizatera igihombo gikomeye. Muri icyo gihe, CMC yibasiwe cyane n'ibipimo by'ibikoresho bya electrode na PH agaciro, kandi urupapuro rwa electrode barashobora gucamo mugihe cyo kwishyuza no kurangiza, bigira ingaruka kubwumutekano wa bateri.

Ku ikubitiro, binder ikoreshwa mubintu bibi bya electrode yari pvdf nibindi bikoresho bishingiye kuri peteroli, ariko urebye ibidukikije nibindi bintu, byabaye umwirondoro wa electrode.

Binder itunganijwe itabaho, gerageza guhitamo binder itujuje ibisabwa bifatika nibisabwa bya electrochemic. Hamwe niterambere ryikoranabuhanga rya bateri rya lithium, hamwe nibibazo byibidukikije nibidukikije, guhuza amazi bishingiye kumazi bizasimbuza imipaka ishingiye kuri peteroli.

CMC Ibice bibiri byingenzi

Dukurikije itangazamakuru ritandukanye, umusaruro w'inganda wa CMC urashobora kugabanywamo ibyiciro bibiri: uburyo bushingiye ku mazi n'uburyo bushingiye ku musaruro. Uburyo bukoresha amazi nkuko reaction yitwa uburyo bwo hagati bwamazi, bukoreshwa mugutanga ibikoresho bisanzwe bya alkaline hamwe na CMC yo hasi. Uburyo bwo gukoresha Solvent nkuko reaction isobanura uburyo bwo gukemura, bukwiriye gukora imisaruro ya CMC. Ibi bisubizo byombi bikorwa mu kagaburibyo, bikaba bigize inzira yo guteka kandi ubu ari uburyo nyamukuru bwo gukora CMC.

Uburyo bwo Gucikamo amazi: Uburyo bwo gutanga umusaruro wambere, uburyo ni ugutwara umukozi wa selile ya alkali hamwe namazi ya alkali. Ibyiza byuburyo bwo hagati bwamazi nuko ibisabwa nibikoresho bisa kandi ikiguzi ni gito; Ingaruka ni uko kubera kubura umubare munini wamazi, ubushyuhe butangwa no kwihutisha ubushyuhe kandi bwihutisha umuvuduko wo kubibona, bikavamo imikorere yo guhagarara no gutanga umusaruro mubi.

Uburyo bwo gukemura; Uzwi kandi nkuburyo bwibinyabuzima, bigabanijwemo uburyo bwo guteka nubu buryo butunguranye ukurikije urugero rwa disction dilunt. Ikirangantego cyacyo nuko ibisubizo bya alkalisation no guhinduranya bikorwa muburyo bwa kama nkuko reaction igabanya ubuciriritse (diluennt) ya. Nkibintu bifatika byuburyo bwamazi, uburyo bworoshye kandi bugizwe nibice bibiri byo alkana no guhagarara, ariko imyifatire yimyitwarire yizi ngingo zombi iratandukanye. Ibyiza byuburyo bworoshye nuko igereka inzira ya Alkali, ikanda, guhonyora, no gusaza, kandi bishaje byose nibikorwa byose bikozwe mukarenge; Ingaruka ni uko ubushyuhe bushingiye ku bushyuhe ari abakene, kandi ibyangombwa byo mu kirere ni bikennye. , igiciro cyo hejuru.
