Mokhoa oa sejoale-joale oa slurry ke:
(1) Lisebelisoa:
1. Tokiso ea tharollo:
a) Karolelano ea motsoako le boima ba PVDF (kapa CMC) le solvent NMP (kapa metsi a ntšitsoeng);
b) Nako e susumetsang, makhetlo a susumetsang le linako tsa tharollo (le mocheso oa holim'a tharollo);
c) Ka mor'a hore tharollo e lokisoe, hlahloba tharollo: viscosity (teko), tekanyo ea solubility (tlhahlobo ea pono) le nako ea sethala;
d) Electrode e mpe: Tharollo ea SBR + CMC, nako e susumetsang le makhetlo a mangata.
2. Lintho tse sebetsang:
a) Lekola hore na karo-karolelano ea ho tsoaka le bongata li nepahetse nakong ea ho bekha le ho kopanya;
b) Ball milling: nako ea ho sila ea li-electrode tse ntle le tse mpe;karo-karolelano ea lifaha tsa agate ho motsoako ka moqomong oa leloala la bolo;karo-karolelano ea libolo tse kholo ho libolo tse nyane ka bolo ea agate;
c) Ho baka: ho beha mocheso oa ho baka le nako;mocheso oa teko ka mor'a ho pholile ka mor'a ho baka.
d) Ho kopanya le ho sisinyeha ha lintho tse sebetsang le tharollo: mokhoa oa ho susumetsa, nako ea ho susumetsa le makhetlo a mangata.
e) Sieve: fetisa 100 letlooeng (kapa 150 mesh) sieve ea molek'hule.
f) Teko le tlhahlobo:
Etsa liteko tse latelang mabapi le slurry le motsoako: litaba tse tiileng, viscosity, fineness ea motsoako, tekano ea pompo, slurry density.
Ntle le tlhahiso e hlakileng ea ts'ebetso ea setso, ho boetse hoa hlokahala ho utloisisa melao-motheo ea lithium betri peista.
Khopolo ea Colloid
