摘要： The present disclosure relates to a thick film electrode and a method for manufacturing the same. Since the thick film electrode uses a photocurable monomer as a processing solvent, it requires no separate drying step and may have a sufficiently large thickness without physical cracking. In addition, since the thick film electrode uses a nonwoven web-type substrate having a carbon body applied to the surface of a conductive polymer, it may have higher ion conductivity and areal capacity. Further, a semi solid-state battery including the thick film electrode may have excellent energy density.

摘要： Disclosed is a secondary battery separator including a cellulose coating layer containing cellulose nanofibers and cellulose nanocrystals on a porous support. The secondary battery separator has a light weight, excellent air permeability and excellent puncture strength, and thus can provide a lithium secondary battery with excellent physical properties, including ion conductivity, wettability with an electrolyte and heat stability.

摘要： Disclosed is a secondary battery separator including a cellulose coating layer containing cellulose nanofibers and cellulose microfibers and prepared by using a specific content of dispersant, on a porous support layer. The secondary battery separator has a light weight, improved air permeability and excellent puncture strength, and thus realizes excellent physical properties, such as lithium-ion conductivity, wettability with an electrolyte and heat stability.
