Iyo yazvino yechinyakare slurry process ndeye:
(1) Zvinosanganisa:
1. Kugadzirira kwemhinduro:
a) Kusanganiswa kwechiyero uye kuyerwa kwePVDF (kana CMC) uye NMP inonyungudutsa (kana mvura yakasvibiswa);
b) Nguva yekukurudzira, kumhanyisa frequency uye nguva dzemhinduro (uye tembiricha yepamusoro yemhinduro);
c) Mushure mokunge mhinduro yacho yagadzirwa, tarisa mhinduro: viscosity (test), dhigirii yekunyungudika (kuonekwa kwekuona) uye nguva yesherufu;
d) Negative electrode: SBR + CMC mhinduro, inomutsa nguva uye frequency.
2. Active substance:
a) Tarisa uone kana chiyero chekusanganisa uye huwandu hwakarurama panguva yekuyera nekusanganisa;
b) Kugaya bhora: nguva yekugaya yemagetsi akanaka uye asina kunaka;chiyero cheagate mabheji kune musanganiswa mubhora reguyo;chiyero chemabhora makuru kune madiki mabhora mu agate bhora;
c) Kubika: kugadzika kwekushisa kwekubikira uye nguva;bvunzo tembiricha mushure mekutonhodza mushure mekubika.
d) Kusanganisa uye kubvongodza kwezvinhu zvinoshanda uye mhinduro: nzira yekukurudzira, nguva yekukurudzira uye kuwanda.
e) Sieve: pfuura 100 mesh (kana 150 mesh) molecular sieve.
f) Kuongorora uye kuongorora:
Ita bvunzo dzinotevera pane slurry uye musanganiswa: yakasimba yemukati, viscosity, musanganiswa fineness, tap density, slurry density.
Pamusoro pekugadzirwa kwakajeka kwemaitiro echinyakare, zvinodikanwawo kuti unzwisise misimboti yekutanga yelithium bhatiri paste.
Colloid dzidziso
Mhedzisiro huru yekukonzera kuunganidzwa kwezvimedu zvecolloidal isimba revan der Waals pakati pezvimedu.Kuti uwedzere kugadzikana kwecolloidal particles, kune nzira mbiri.Imwe ndeyekuwedzera electrostatic repulsion pakati pecolloidal particles, uye imwe ndeyekugadzira nzvimbo pakati pehupfu.Kudzivirira kuungana kwehupfu munzira mbiri idzi.
Iyo yakapfava colloidal system inoumbwa nechikamu chakapararira uye yakapararira yepakati, uko chiyero chechikamu chakapararira chinotangira kubva pa10-9 kusvika 10-6m.Zvinhu zviri mucolloid zvinofanirwa kunge zvine imwe nhanho yekuparadzira kugona kuvepo muhurongwa.Zvinoenderana neakasiyana zvinonyungudutsa uye akapararira zvikamu, akawanda akasiyana colloidal mafomu anogona kugadzirwa.Semuenzaniso, mhute iaerosol umo madonhwe anoparadzirwa mugasi, uye mushonga wemazino isol umo yakasimba polymer particles inoparadzirwa mumvura.
Kushandiswa kwemacolloid kunowanda muhupenyu, uye zvimiro zvemacolloids zvinoda kuve zvakasiyana zvichienderana nechikamu chekuparadzira uye svikiro rekuparadzira.Tichicherechedza iyo colloid kubva pane microscopic yekuona, iyo colloidal particles haisi mumamiriro ekugara, asi kufamba zvisina kufanira mukati mepakati, iyo yatinoti Brownian motion (Brownian motion).Pamusoro pemhedziso zero, colloidal particles ichaita Brownian motion nekuda kwekupisa kwekufamba.Aya ndiwo masimba e microscopic colloids.Colloidal particles inodhumhana nekuda kweBrownian motion, inova mukana wekuunganidza, nepo colloidal particles ari mu thermodynamically isina kugadzikana mamiriro, saka kupindirana kwesimba pakati pezvimedu ndechimwe chezvinhu zvakakosha zvekupararira.
