A lithium ion secondary battery is provided, including: a positive electrode and a negative electrode into which, and from which, lithium ions can be introduced and be discharged reversibly, and an electrolyte membrane placed therebetween, wherein the electrolyte membrane is obtained using an electrolyte made by blending (A) a polyanion type lithium salt, (B) a boron compound, and (C) an organic solvent.
摘要:
The whole of a conductive material layer is formed on a bonding surface of an outer film having flexibility and barrier properties to prepare a composite body in which the conductive material layer is integrated with the outer film. A current collector is located within an application region, and at least a part of an electrode terminal is located outside the application region. A positive electrode active material precursor layer, an electrolyte precursor layer, and a negative electrode active material precursor layer are added to the composite body with plane positions thereof aligned with that of the current collector. These precursor layers are subjected to a crosslinking process. The application regions are applied, and the outer films are bonded, to seal a cell. The crosslinking process may be omitted.

摘要:
Fumaric acid derivatives and ophthalmic lenses using them are disclosed. More specifically, a fumaric acid derivative having a hydrophilic group and a silicon-containing alkyl group within a molecule, and contact lenses or intraocular lenses using the same are disclosed. The fumaric acid derivatives of the present invention provide, on one hand, superior oxygen permeability by having a silicon-containing alkyl group within the molecular structure, and on the other hand, improved compatibility with other hydrophilic monomers by having a hydrophilic group within the same molecule. When ophthalmic lenses obtained by polymerizing monomer compositions containing the fumaric acid derivative are constructed as, for example, water content lenses, lenses with high oxygen permeability independent from the water content may be obtained, wherein the fumaric acid derivatives is superior in compatibility with the hydrophilic monomer used in combination and allows the combination in various mixing ratios.

The present invention provides an inexpensive solid-state polymer electrolyte membrane to be used in a solid-state polymer electrolyte fuel cell, which can be manufactured by using inexpensive raw materials through a simpler chemical synthesis process, achieves good heat resistance and demonstrates superior proton conductivity at low humidity. A primary constituent of the solid-state electrolyte polymer film to be used in a solid-state polymer electrolyte fuel cell according to the present invention is a hyperbranched polymer having an acidic functional group such as sulfonic acid disposed at the terminal of a side chain thereof. The hyperbranched polymer may be, for instance, poly[(bis(oligo-ethylene glycol) benzoate)].
摘要:
This invention relates to a matrix of a solid electrolyte having a microstructure in which a non-reactive polyalkylene glycol is held on a co-crosslinked product produced by chemically co-crosslinking a hyperbranched polymer with a crosslinkable ethylene oxide multicomponent copolymer, such that a lithium salt is dissolved in the matrix. A negative electrode active material layer is a layer obtained by dispersing a negative electrode active material and a conduction aid in a lithium-ion conducting solid electrolyte. A positive electrode active material layer is a layer obtained by dispersing a positive electrode active material and a conduction aid in a lithium-ion conducting solid electrolyte.
