1. Ukuqinisekisa ukuhambelana kwengubo, kufuneka ihlawulwe kwinguqu kwi-viscosity ye-slurry, utshintsho ekuphakameni kwe-hopper, utshintsho kwisantya sokutya; 2, umaleko obhityileyo we-slurry kwifoyile ye-aluminium kwi-oven eyomileyo, susa i-NMP Solvent (indawo yokubilisa ye-NMP 202 ¡ã C, i-flash point 95 ¡ã C). Ukomisa kucotha kakhulu, umphezulu we-coating yi-fluidity, ubukhulu abuzinzile, ukomiswa kukhawuleza kakhulu, umphezulu wenza umaleko wefilimu ye-PVDF, kwaye i-solvent ye-NMP yangaphakathi i-volatilizes inokubangela ukuba umaleko womphezulu ushwabene, ukuze kuqinisekiswe ukuphuphuma komyinge we-NMP, ngokuqhelekileyo kusetyenziswa ukomisa okucandiweyo, Ukushisa okuphezulu kwinqanaba eliphakathi.

I-electrode efanelekileyo ngokuqhelekileyo yi-100-130 ¡ã C, ukuba i-aqueous system isetyenzisiweyo, ukushisa kokumisa ngokuqhelekileyo ku-75-90 ¡ã C; kunye nenkqubo yokomisa i-NMP i-volatilizes, ukubunjwa kwe-coating paste ihlala iguquka, ngoko ke inani le-NMP ye-solvent ye-slurry, ukunyuka kweqondo lokushisa Imo kunye nexesha lokufudumeza linefuthe kule nto; Into esebenzayo iya kuhluthwa, ngaloo ndlela ibangele isiphaluka esifutshane kwibhetri. Ukongezelela, ukushisa kokumisa kunye nexesha lokumisa akubangelwa ngokufanelekileyo yi-aluminium foil oxidation kunye ne-polarity polarity; I-4, ukugquma kunye nokumisa kufuneka kube yinto yokuqala yokuhlola ezintathu - ubukhulu, umgangatho, ubungakanani buhlangabezana neemfuno, kunye nokuvavanya i-pulp ehambelanayo ngexesha Isantya, ixesha lokubhaka, i-gap, njl. Inkcazo yeentambo ezimnyama zemicu yokugquma: Ubumnyama bubangelwa ukugquma, isahlulo somphezulu we-polar surface ayilingani, umehluko wombala uyenzeka, kwaye ukubonakala kumnyama.

Umahluko kubunzima bunokuba (1) ngenxa yencakuba yento yangaphandle okanye umphezulu wemela eludaka (unesithuba), ubangele isenzeko sokuba ubukhulu bomphezulu wepali bungalingani; (2) emva koxinzelelo lwe-roller okanye uxinzelelo lwe-roller Umkhondo we-linear. Ngenxa yeengqungquthela ezingavulwanga ngenxa yemela, okanye ikhadi elincinci elomileyo le-slurry libangelwa kwi-kn.
