摘要:
A non-aqueous electrolyte secondary battery (100) includes: an electrode body (150) including a positive electrode plate (155), a negative electrode plate (156), and a separator (157); and a non-aqueous electrolyte contained inside the electrode body (150). The non-aqueous electrolyte secondary battery (100) further includes a reservoir member (170) defining a reservoir space (S1, S2) located adjacent to an end face (150j, 150k) of the electrode body (150), the reservoir space being used to hold the non-aqueous electrolyte forced out of the electrode body (150) through the end face (150j, 150k) of the electrode body (150).
摘要:
In an electrode body for use in non-aqueous electrolyte secondary battery, a first end of a separator is located more interiorly than one positive electrode end of a positive electrode plate in a width direction, located more exteriorly than one end of a coated positive electrode portion of the positive electrode plate, and located more exteriorly than one end of a coated negative electrode portion of a negative electrode plate. The first end of the separator is thicker than an intermediate portion. A second end of the separator is located more interiorly than an other negative electrode end of the negative electrode plate in the width direction, located more exteriorly than the other end of the coated positive electrode portion of the positive electrode plate, and located more exteriorly than an other end of the coated negative electrode portion of the negative electrode plate. The second end of the separator is thicker than the intermediate portion.

A lithium ion secondary battery includes a flat wound electrode body including a positive electrode sheet and a negative electrode sheet that are wound while interposing therebetween separators into a flat shape, and a battery case. In the flat wound electrode body, a central portion has a more constricted shape than end portions by pressing toward a winding axis in a short-side direction and each end portion includes an end-portion positive electrode sheet, an end-portion negative electrode sheet, and end-portion separators, and a core member arranged more inward than them. With tensile forces generated by pressing of the central portion in a central-portion positive electrode sheet, central-portion negative electrode sheet, and central-portion separators, the end-portion positive electrode sheet, end-portion negative electrode sheet, and end-portion separators are in pressure contact with each other and press the outer surfaces of the core member.

There is provided a particle detector that can increase a detection sensitivity to fluorescence emitted from biogenic particles. A particle detector for detecting biogenic particles includes a substrate having a principal surface and configured to collect the biogenic particles on the principal surface, a light emitting element configured to irradiate particles collected on the principal surface with excitation light, and a light receiving element configured to receive fluorescence emitted from the particles when the particles are irradiated with the excitation light from the light emitting element. An optical axis of the Fresnel lens and a ray direction of the excitation light intersect with each other. The principal surface is a mirror surface.

An imaging device comprises: a lens housing on which lens groups are mounted and which has a first opening opened along an optical axis direction of the lens groups; and a drive housing on which a drive source for moving the lens groups in the optical axis direction is mounted and which has a drive-use opening to be communicated with the first opening of the lens housing. The lens housing and the drive housing are combined together so as to be separable from each other in a state that the first opening and the drive-use opening are communicated with each other.
