摘要: In a secondary battery including a positive electrode, a negative electrode and a porous film bonded to the surface of at least one of the positive electrode and the negative electrode, the porous film includes ceramic particles and a binder, and the ceramic particles include polycrystalline particles obtained by mechanically crushing a fired material comprising a ceramic that is directly synthesized from a ceramic precursor. The porous film has a porosity of 40 to 80%, for example. The porous film can be formed by a method including the steps of: obtaining a fired material comprising a ceramic from a ceramic precursor; obtaining ceramic particles by mechanically crushing the fired material of the ceramic; obtaining a slurry including the ceramic particles and a binder; and applying the slurry onto the surface of an electrode, followed by drying.

摘要: Members with excellent water- and oil-repelling, and anti-contaminating properties are provided by exposing fillers partially protruding from the surfaces of fiber reinforced plastics or fiber reinforced metals and chemically adsorbing a chlorosilane-based chemical adsorbent to the rough surface of the fiber reinforced plastic or metal substrate. A siloxane-based chemically adsorbed monomolecular film or a polysiloxane chemically adsorbed film is formed on the substrate by chemically adsorbing a chemical adsorbent having numerous chlorosilane groups to the substrate surface. Following that, a chlorosilane-based chemical adsorbent having fluorocarbon groups is chemically adsorbed to the film, thus forming a chemically adsorbed monomolecular or polymer film with water- and oil-repelling properties.

摘要: A secondary battery includes: a positive electrode; a negative electrode; a porous electron-insulating layer adhered to a surface of at least one selected from the group consisting of the positive electrode and the negative electrode; and an electrolyte. The porous electron-insulating layer comprises a particulate filler and a resin binder, and the particulate filler comprises an indefinite-shape particle comprising a plurality of primary particles that are joined to one another. A neck is preferably formed between the primary particles. Since the porous electron-insulating layer has high porosity, it is possible to obtain a secondary battery that exhibits excellent low-temperature characteristics, which are particularly important in actual use, and that is capable of discharging at a large current.
