Abstract:
1. A method for coating a moving web with a coating solution containing: one or more nanocrystalline, nanoporous inorganic compounds selected from the group consisting of transition metal oxides, transition metal chalcogenides, and their Li inclusion complexes, wherein the nanocrystalline, nanoporous inorganic compound is TiO 2 , Ti 2 O 3 , Nb 2 O 5 , WO 3 , HfO 2 , TiS 2 , WS 2 , TiSe 2 , Fe 2 O 3 , Fe 3 O 4 , RuO 2 , RuS 2 , MoS 2 , WS 2 IrO 2 , CeO 2 , InO 2 , TaO 2 , ZnO, SnO 2 , BaTiO 3 , SrTiO 3 , indium-tin-oxide, LiMn 2 O 4 , LiNiO 2 , LiCoO 2 , or Li(NiCo)O 2 ; and one or more binders in an amount from 0.5% to 30% by weight of the nanocrystalline, nanoporous inorganic compounds, wherein an auxiliary coating solution is applied together with said coating solution to the web, wherein said auxiliary coating solution contains at least one gelation-promoting ingredient which promotes gelation of the coating solution containing the nanocrystalline, nanoporous inorganic compounds, and wherein the coating solution containing the nanocrystalline, nanoporous inorganic compounds forms the electrically conductive layer of an electrically active film.
