Ukusetshenziswa kwe-Sodium Carboxymethyl Cellulose kubhethri lesibili le-Electrolyte elingenamanzi

I-Sodium carboxymethyl cellulose (NaCMC) iyi-polymer encibilikayo emanzini, enesisindo esikhulu samangqamuzana etholakala ku-cellulose. Izakhiwo zayo eziyingqayizivele, njengokugcinwa kwamanzi amaningi, ikhono elihle kakhulu lokwenza ifilimu, nokuzinza okuhle, kuyenza ibe isithako esibalulekile ezinhlobonhlobo zezicelo zezimboni. Eminyakeni yamuva nje, i-NaCMC iqhamuke njengekhandidethi elithembisayo elizosetshenziswa kumabhethri esibili e-electrolyte angenawo amanzi ngenxa yekhono layo lokuthuthukisa ukusebenza kwebhethri nokuphepha. Kulesi sihloko, sizoxoxa ngokusetshenziswa kwe-NaCMC kumabhethri esibili e-electrolyte angenawo amanzi.

Amabhethri esibili e-electrolyte angenamanzi asetshenziswa kakhulu ezintweni zikagesi eziphathwayo, ezimotweni zikagesi, nezinhlelo zokugcina amandla ngenxa yokuminyana kwazo okuphezulu nempilo yomjikelezo omude. Kodwa-ke, ukusetshenziswa kwama-electrolyte angenawo amanzi kubangela ukukhathazeka okuthile kokuphepha, njengokungazinzi kokushisa, ukuvutha nokuvuza. I-NaCMC ikhonjiswe ukuthi ibhekana nalezi zinkinga ngokwenza ngcono ukuphepha nokusebenza kwamabhethri esibili e-electrolyte angenawo amanzi.

1. Ukuzinza kwe-Electrolyte: Ukuzinza kwe-electrolyte kubalulekile ekusebenzeni nasekuphepheni kwebhethri. I-NaCMC ingathuthukisa ukuzinza kwe-electrolyte ngokunciphisa izinga lokuhwamuka kwayo, ivimbele ukuvuza, nokwandisa i-viscosity ye-electrolyte. Ukwengezwa kwe-NaCMC nakho kunganciphisa ukubola kwe-electrolyte futhi kwandise ukuzinza kwayo okushisayo.
2. I-ion conduction: I-NaCMC ingathuthukisa ukuqhutshwa kwe-ion ye-electrolyte ngokwenza inethiwekhi efana nejeli eyenza kube lula ukuthuthwa kwama-ion e-lithium phakathi kwama-electrode. Lokhu kubangela ukusebenza kwebhethri okuthuthukisiwe kanye nempilo yomjikelezo omude.
3. Ukuphepha kwebhethri: I-NaCMC ingathuthukisa ukuphepha kwebhethri ngokuvimbela ukwakheka kwama-dendrite, okuyizakhiwo ezifana nenaliti ezingakhula ukusuka ebusweni be-anode futhi zingene kusihlukanisi, okuholela ekubalekeni kwe-short-circuiting kanye ne-thermal. I-NaCMC ingaphinde ithuthukise ukuzinza kwemishini ye-electrode futhi ivimbele ukuhlukaniswa kwayo kumqoqi wamanje, inciphise ubungozi bezifunda ezimfushane zangaphakathi.
4. Ukuzinza kwe-Electrode: I-NaCMC ingathuthukisa ukuzinza kwe-electrode ngokwenza i-coating efanayo ebusweni bayo, engavimbela ukuchithwa kwezinto ezisebenzayo futhi inciphise ukulahlekelwa kwamandla ngokuhamba kwesikhathi. I-NaCMC ingaphinde ithuthukise ukunamathela kwe-electrode kumqoqi wamanje, okuholela ekuziphatheni okuthuthukisiwe nokunciphisa ukumelana.

Sengiphetha, i-NaCMC iyisengezo esithembisayo esingasetshenziswa kumabhethri esibili e-electrolyte angenawo amanzi ngenxa yekhono layo lokuthuthukisa ukusebenza kwebhethri nokuphepha. Izakhiwo zayo eziyingqayizivele, njengokugcinwa kwamanzi amaningi, ikhono elihle kakhulu lokwenza ifilimu, nokuzinza okuhle, kuyenza ibe yisengezo esiphumelelayo sokuthuthukisa ukuzinza kanye ne-ion conduction ye-electrolyte, ukuvimbela ukwakheka kwama-dendrites, ukuthuthukisa ukuzinza kwemishini ye-electrode, kanye nokunciphisa ukulahleka kwamandla ngokuhamba kwesikhathi. Ukusetshenziswa kwe-NaCMC kungaholela ekuthuthukisweni kwamabhethri esibili e-electrolyte aphephile futhi asebenza kahle kakhulu, angaba nomthelela omkhulu ekuthuthukisweni kwemboni yezimoto zikagesi kanye nomkhakha wokugcina amandla.
