1. Ukuqinisekisa ukuhambisana kokugqoka, kufanele kukhokhwe ekushintsheni kwe-viscosity ye-slurry, ushintsho ekuphakameni kwe-hopper, izinguquko kwijubane lokugqoka; 2, ungqimba oluncane lwe-slurry kucwecwe lwe-aluminium kuhhavini lomile, susa i-NMP Solvent (iphoyinti elibilisayo le-NMP 202 ¡ã C, iphoyinti elikhanyayo 95 ¡ã C). Ukomisa kuhamba kancane, ingaphezulu le-coating liyi-fluidity, ukushuba akuzinzile, ukomisa kuyashesha kakhulu, indawo engaphezulu yakha ungqimba lwefilimu ye-PVDF, futhi i-solvent ye-NMP yangaphakathi iyashintshashintsha ingabangela ungqimba olungaphezulu ukuba lushwabene, ukuze kuqinisekiswe ukuhwamuka okujwayelekile kwe-NMP, ngokuvamile sebenzisa ukomisa okuhlukene, Izinga lokushisa eliphakeme kakhulu esigabeni esiphakathi.

I-electrode enhle imvamisa ingu-100-130 ¡ã C, uma kusetshenziswa uhlelo lwamanzi, izinga lokushisa lokumisa livamise ukuba ngu-75-90 ¡ã C; futhi inqubo yokomisa i-NMP iyashintshashintsha, ukwakheka kwe-coating paste kushintsha njalo, ngakho-ke inani le-NMP solvent ye-slurry, ukuphakama kwezinga lokushisa Imodi nesikhathi sokushisa sinomthelela kulokhu; Into esebenzayo izoxebuka, ngaleyo ndlela kubangele ukujikeleza okufushane ebhethrini. Ukwengeza, izinga lokushisa lokumisa nesikhathi sokumisa akubangelwa ngokufanelekile i-aluminium foil oxidation kanye ne-polarity polarity; I-4, ukugqoka nokomisa kufanele kube ukuhlolwa kokuqala okuthathu - ukujiya, ikhwalithi, usayizi uhlangabezana nezidingo, futhi uhlole i-pulp ehambisanayo ngesikhathi Isivinini, isikhathi sokubhaka, igebe, njll. Incazelo yezintambo ezimnyama zezintambo zokumboza: Ubumnyama bubangelwa ukumbozwa, ingxenye engaphezulu ye-polar surface ayilingani, umehluko wombala uvela, futhi ukubukeka kumnyama.

Umehluko ekujikeni ungaba (1) ngenxa yensingo yento yangaphandle noma ingaphezulu lommese endaweni edakanayo (ibe nesikhala), okubangela into yokuthi ukujiya kwengaphezulu kwendawo yesigxobo akulingani; (2) ngemva kokucindezela kwe-roller noma ingcindezi ye-roller Iminonjana yomugqa. Ngenxa yezinhlayiya ezingavuleki ngenxa yommese, noma ikhadi elincane le-slurry elomile libangelwa ku-kn.
