I-Nano cellulose endaweni yokugcina amandla- isihlukanisi sebhethri ye-lithium

1. Ukusebenza okuzinzile

Umsebenzi oyinhloko wezinto zefilimu ezisekelwe ku-nano cellulose ukuhlukanisa ama-electrode amahle nangalungile, angavumela kuphela ukudluliswa okusheshayo kwama-ion phakathi kwama-electrode aqondile namabi.Ingenye yezingxenye ezibalulekile zangaphakathi zemishini yokugcina amandla.Ukusebenza kwe-diaphragm kunomthelela omkhulu ekuphikisweni kwangaphakathi, amandla okukhipha, impilo yomjikelezo wedivayisi yokugcina kanye nokuphepha kwebhethri.Uma ukuzinza okushisayo, izakhiwo ezimpofu zemishini, ukwakheka kwe-pore ephansi nezinye izinkinga kuzodala isifunda esifushane sebhethri noma kuvimbele ukudluliswa kwe-ion nezinye izidingo, ukusetshenziswa kwe-nano cellulose nano cellulose esekelwe isihlukanisi izinto kungaxazulula kahle le nkinga.

2. Izakhiwo ze-Electrochemical

Uma kuqhathaniswa ne-cellulose fiber, isakhiwo se-nano kanye nendawo ethile ye-nano cellulose kuhle kakhulu.Izinto ze-electrode zingaba nesakhiwo esihle kakhulu se-nano kanye nezakhiwo ezinhle kakhulu ze-electrochemical nge-high-temperature carbonization, i-in-situ chemical polymerization, i-electrochemical deposition nezinye izindlela.

3. Ukuphepha nokuhlehliswa

Izinto ezisetshenziswa yi-nanocellulose esekelwe kwi-carbon fiber Izinto ze-Carbon fibre zinokuhlehla phezulu nokuphepha.Eminyakeni yamuva nje, ama-carbon nanofibers, ikakhulukazi alungiselelwe kusuka kushukela, ama-polymers kanye ne-cellulose, adonse ukunaka kwabantu ngenxa yendawo yawo enkulu kanye nesakhiwo senethiwekhi esinezinhlangothi eziningi, okubenza babe nezici ezihlehliswayo nezingcono kakhulu zokuhamba ngebhayisikili lapho besetshenziswa ezintweni zokugcina amandla ze-electrode.

4. Usayizi omuhle

Phakathi kwama-nanomaterials asekelwe ku-cellulose anezinhlangothi ezimbili, ama-nanomaterials anezinhlangothi ezimbili abhekisela kuma-nanomaterials anosayizi we-nanometer (imvamisa engu-≤ 10 nm) ku-dimension eyodwa kuphela kanye nosayizi we-macroscopic kwezinye izilinganiso ezimbili.Ngenxa yezakhiwo zabo ezinhle kakhulu zemishini, indawo enkulu ethize engaphezulu, kanye nokuhanjiswa okuphezulu, zisetshenziswa kakhulu endaweni yokugcina amandla, izinzwa, amadivaysi e-elekthronikhi aguquguqukayo, njalonjalo.Kodwa-ke, ngenxa yenani elincane lamaqembu angaphezulu kanye nomsebenzi ophansi wamakhemikhali, kukhona ama-clumps nokuhlakazeka okungalingani esixazululweni.Ngaphambi kokusetshenziswa, kuyadingeka ukwengeza ama-surfactants noma ukwenza ukwelashwa kwe-chemical oxidation reaction ukuze wenze indawo yayo ibe namaqembu ahlukahlukene aqukethe umoya-mpilo ukuze kuthuthukiswe umsebenzi wayo ongaphezulu.

5. Kuyasebenziseka

Ngocwaningo lwe-nano cellulose esekelwe ezingxenyeni eziningi ze-component, kutholakala ukuthi ukuthuthukisa ukusebenza kwe-electrochemical ye-nano cellulose esekelwe izinto ze-electrode kungenza kube nokwenzeka ukwakha isakhiwo se-nano electrode esicwengekile nesisebenzayo.Izinhlanganisela ze-nano cellulose ezisekelwe ezintweni eziningi zingalungiswa nge-carbonization, i-chemical in-situ polymerization, i-electrochemical deposition, ukusabela kwe-hydrothermal kanye nokuzihlanganisa.
