I-Nano cellulose kwindawo yokugcina amandla- isahluli sebhetri ye-lithium

1. Ukusebenza okuzinzileyo

Umsebenzi oyintloko wezinto zefilimu ezisekelwe kwi-nano cellulose kukuhlukanisa i-electrodes efanelekileyo kunye ne-negative, enokuthi ivumele ukuhanjiswa ngokukhawuleza kwee-ion phakathi kwee-electrodes ezintle kunye nezibi.Yenye yezinto ezibalulekileyo zangaphakathi zezixhobo zokugcina amandla.Ukusebenza kwe-diaphragm kunempembelelo enkulu ekuchaseni kwangaphakathi, umthamo wokukhupha, ubomi bomjikelezo wesixhobo sokugcina kunye nokukhuselwa kwebhetri.Ukuba ukuzinza kwe-thermal, iipropati ezihluphekileyo zomatshini, ubume obuphantsi be-pore kunye nezinye iingxaki ziya kubangela i-battery isiphaluka esifutshane okanye ithintele ukuhanjiswa kwe-ion kunye nezinye iimfuno, ukusetyenziswa kwe-nano cellulose nano cellulose esekelwe kwi-separator materials inokusombulula kakuhle le ngxaki.

2. Iimpawu ze-Electrochemical

Xa kuthelekiswa nefiber cellulose, isakhiwo se-nano kunye nommandla othile we-nano cellulose ulungile.Izinto ze-electrode zinokuba nesakhiwo esihle kakhulu se-nano kunye neempawu ezibalaseleyo ze-electrochemical nge-carbonization ephezulu yobushushu, i-in-situ chemical polymerization, i-electrochemical deposition kunye nezinye iindlela.

3. Ukhuseleko kunye nokubuyisela umva

I-Nanocellulose esekelwe kwi-carbon fiber materials Izixhobo ze-carbon fiber zinokuguqulwa okuphezulu kunye nokhuseleko.Kwiminyaka yakutshanje, ii-carbon nanofibers, ezilungiselelwe ikakhulu kwiswekile, iipolymers kunye neselulosi, ziye zatsala umdla wabantu ngenxa yendawo yazo enkulu kunye ne-multi-dimensional network structure, ezenza ukuba ziguquke ngakumbi kwaye zibe ngcono iimpawu zokuhamba ngebhayisikile xa zisetyenziswa kwisixhobo sokugcina amandla izixhobo ze-electrode.

4. Ubungakanani obuhle

Phakathi kwe-cellulose esekelwe kwi-nanomatadium ene-dimensional-dimensional, i-nanomaterials e-dimensional ibhekisela kwi-nanomaterials enobungakanani be-nanometer (ngokuqhelekileyo ≤ 10 nm) kwi-dimension enye kuphela kunye nobukhulu be-macroscopic kwezinye imilinganiselo emibini.Ngenxa yeepropathi zabo ezigqwesileyo zoomatshini, indawo enkulu yendawo ethile, kunye ne-conductivity ephezulu, zisetyenziswa ngokubanzi kugcino lwamandla, izinzwa, izixhobo zombane eziguquguqukayo, njalo njalo.Nangona kunjalo, ngenxa yenani elincinci lamaqela angaphezulu kunye nomsebenzi ophantsi weekhemikhali, kukho i-clumps kunye nokusabalalisa okungalinganiyo kwisisombululo.Ngaphambi kokusetyenziswa, kuyimfuneko ukongeza i-surfactants okanye ukwenza unyango lwe-chemical oxidation reaction ukuze wenze umphezulu wayo ube neentlobo ezahlukeneyo ze-oksijini eziqulethe amaqela okuphucula umsebenzi wawo.

5. Iyaphucuka

Ngophando malunga ne-nano cellulose esekelwe kwii-composites ze-multi-component composite, kufunyenwe ukuba ukuphuculwa kwentsebenzo ye-electrochemical ye-nano cellulose esekelwe kwizinto ze-electrode kunokukwenza ukuba kube lula ukwakha i-nano electrode ephuculweyo kwaye isebenzayo.I-nano cellulose ephuculweyo esekelwe kwi-multi-component composite ingalungiswa nge-carbonization, i-chemical in-situ polymerization, i-electrochemical deposition, i-hydrothermal reaction and self-assembly.
