Inkqubo yangoku yodaka yile:
(1) Izithako:
1. Ukulungiswa kwesisombululo:
a) Umlinganiselo wokuxuba kunye nobunzima bePVDF (okanye iCMC) kunye neNMP yesinyibilikisi (okanye amanzi adiyoni);
b) Ixesha lokuvuselela, ukuphindaphinda kunye namaxesha esisombululo (kunye nobushushu bomhlaba wesisombululo);
c) Emva kokuba isisombululo silungisiwe, khangela isisombululo: i-viscosity (uvavanyo), i-degree of solubility (ukuhlolwa okubonakalayo) kunye nexesha leshelufu;
d) I-electrode engalunganga: Isisombululo se-SBR + CMC, ixesha lokuvuselela kunye nokuphindaphinda.
2. Into esebenzayo:
a) Beka iliso ukuba ngaba umlinganiselo wokuxuba kunye nobungakanani buchanekile ngexesha lokulinganisa kunye nokuxuba;
b) Ukugaya ibhola: ixesha lokusila lee-electrode ezilungileyo kunye nezingalunganga;umlinganiselo weentsimbi ze-agate kumxube kwi-barrel yebhola yebhola;umlinganiselo weebhola ezinkulu kwiibhola ezincinci kwibhola ye-agate;
c) Ukubhaka: ukubeka ubushushu bokubhaka kunye nexesha;uvavanyo lobushushu emva kokupholisa emva kokubhaka.
d) Ukuxuba kunye nokuxutywa kwezinto ezisebenzayo kunye nesisombululo: indlela yokuvuselela, ixesha lokuvuselela kunye nokuphindaphinda.
e) Isihluzo: dlula i-100 mesh (okanye i-150 mesh) i-molecular sieve.
f) Uvavanyo nokuhlolwa:
Yenza olu vavanyo lulandelayo kwi-slurry kunye nomxube: umxholo oqinileyo, i-viscosity, i-coneness yomxube, ubuninzi bompompo, ubuninzi be-slurry.
Ukongeza kwimveliso ecacileyo yenkqubo yendabuko, kuyimfuneko kwakhona ukuqonda imigaqo esisiseko ye-lithium ibhetri yokunamathisela.
Ithiyori yeColloid
Impembelelo ephambili yokubangela ukuxutywa kwamasuntswana e-colloidal yi-van der Waals force phakathi kwamasuntswana.Ukwandisa ukuzinza kwee-colloidal particles, kukho iindlela ezimbini.Enye kukwandisa i-electrostatic repulsion phakathi kwamasuntswana e-colloidal, kwaye enye kukudala isithuba phakathi komgubo.Ukuthintela i-agglomeration ye powders kwezi ndlela zimbini.
Inkqubo ye-colloidal elula iqulunqwe yinqanaba elichithwayo kunye ne-dispersed medium, apho umlinganiselo wesigaba esichithwayo sisuka kwi-10-9 ukuya kwi-10-6m.Izinto ezikwi-colloid kufuneka zibe neqondo elithile lokukwazi ukusasazeka ukuze zibekho kwinkqubo.Ngokutsho kwee-solvents ezahlukeneyo kunye nezigaba ezihlakaziweyo, ezininzi iifom ze-colloidal ezahlukeneyo zinokuveliswa.Ngokomzekelo, inkungu yi-aerosol apho amathontsi asasazwa kwi-gas, kwaye intlama yamazinyo yi-sol apho amasuntswana e-polymer aqinileyo ahlakazwa kulwelo.
Ukusetyenziswa kwe-colloids kuninzi ebomini, kwaye iimpawu ezibonakalayo ze-colloids kufuneka zihluke ngokuxhomekeke kwisigaba sokusabalalisa kunye ne-dispersion medium.Ukuqwalasela i-colloid ukusuka kwindawo yokujonga i-microscopic, iinqununu ze-colloidal azikho kwimeko eqhubekayo, kodwa zihamba ngokungaqhelekanga kwi-medium, into esiyibiza ngokuba yi-Brownian motion (i-Brownian motion).Ngaphezulu kwe-absolute zero, amasuntswana e-colloidal aya kuqhuba intshukumo yeBrownian ngenxa yentshukumo yobushushu.Oku kukutshintsha kweecolloids ezincinci.Iingqungquthela ze-Colloidal zingqubuzana ngenxa yokunyakaza kwe-Brownian, okuyithuba lokudibanisa, ngelixa i-colloidal particles ikwimeko engazinzanga ye-thermodynamically, ngoko ke amandla okusebenzisana phakathi kwamaqhekeza yenye yezinto eziphambili zokusabalalisa.
