1. Ho etsa bonnete ba ho lumellana ha ho roala, ho lokela ho lefshoa ho fetoha ha viscosity ea slurry, phetoho ea bophahamo ba hopper, liphetoho ka lebelo la ho roala; 2, lesela le tšesaane la slurry holim&39;a foil ea aluminium ka ontong e omeletseng, tlosa NMP Solvent (NMP e belang ntlha 202 ¡ã C, ntlha ea flash 95 ¡ã C). Ho omisa ho lieha haholo, bokaholimo ba ho roala bo na le metsi, botenya ha bo tsitsa, ho omisa ho potlakile haholo, bokaholimo bo etsa lera la filimi ea PVDF, &39;me karolo e ka hare ea NMP solvent volatilizes e ka etsa hore lera la holim&39;a metsi le sosobane, e le ho etsa bonnete ba hore ho na le mouoane o tloaelehileng oa NMP, hangata o sebelisa ho omisa ka likarolo, Mocheso o phahameng ka ho fetisisa karolong e bohareng.

Electrode e ntle ka kakaretso ke 100-130 ¡ã C, haeba tsamaiso ea metsi e sebelisoa, mocheso oa ho omisa hangata ke 75-90 ¡ã C; le ts&39;ebetso ea ho omisa NMP e fetoha, sebopeho sa pente ea ho roala e lula e fetoha, kahoo palo ea NMP solvent ea slurry, ho phahama ha mocheso Mokhoa le nako ea ho futhumatsa e na le phello ho sena; Ntho e sebetsang e tla ebolloa, kahoo e baka potoloho e khuts&39;oane ka har&39;a betri. Ho phaella moo, mocheso oa ho omisa le nako ea ho omisa ha o bakoe ka mokhoa o nepahetseng ke aluminium foil oxidation le polarity polarity; 4, ho roala le ho omisa e lokela ho ba tlhahlobo ea pele e meraro - botenya, boleng, boholo bo finyella litlhoko, &39;me u leke makhasi a tsamaisanang ka nako Lebelo, nako ea ho baka, lekhalo, joalo-joalo. Tlhaloso ea likhoele tse lefifi tsa likhoele tsa ho roala: Lefifi le bakoa ke ho roala, karolo e ka holimo ea sebaka sa polar ha e lekane, phapang ea mebala e hlaha, &39;me ponahalo e lefifi.

Phapang ka botenya e ka &39;na ea e-ba (1) ka lebaka la lehare la lintho tse tsoang linaheng tse ling kapa holim&39;a thipa ka slurry (e na le lekhalo), e leng se bakang ketsahalo ea hore botenya ba holim&39;a palo ha bo lekane; (2) ka mor&39;a khatello ea rolara kapa khatello ea roller Linear traces. Ka lebaka la likaroloana tse sa buleheng ka lebaka la thipa, kapa karete e nyenyane e omeletseng ea slurry e bakoa ke kn.
