Battery and related manufacturing method
View Patent ↗A battery is provided with a support body, a surface of the support body, a plurality of unit cells located inside the support body, and an opening portion communicating between an inside and an outside of the support body. A resonance is allowed in the surface of the support body and the opening portion is provided in the surface of the support body at a region involving a loop position of the resonance.
1. A battery comprising:
a support body comprising opposing top and bottom surfaces and two pairs of opposing lateral surfaces;
a resonance being allowed in the surfaces of the support body with a resonance frequency;
a plurality of laminated unit cells located inside the support body and respectively having electrodes, each of the plurality of unit cells being a thin-type laminated cell which has a smaller thickness thereof in a thickness direction, in which the electrodes are stacked, than thickness in other directions thereof, wherein
said unit cells are located between said opposing top and bottom surfaces and said two pairs of opposing lateral surfaces of said support body; and
an opening portion provided in a plurality of the surfaces of the support body to be set at regions involving a loop position of the resonance in order to shift the resonance frequency to a higher frequency range, while communicating between an inside space in which the plurality of laminated unit cells are located and an outside of the support body, the opening portion being formed in at least one surface of the opposing top and bottom surfaces and the two pairs of opposing lateral surfaces of the support body that is parallel to the thickness direction of each of the plurality of unit cells.
2. The battery according to claim 1 , wherein the top and bottom surfaces of the support body are in contact with the opposing lateral surfaces.
3. The battery according to claim 1 , wherein each pair of the two pairs of opposing lateral surfaces are positioned orthogonal to each other.
4. A battery comprising:
a support body comprising opposing top and bottom surfaces and opposing lateral surfaces;
a resonance being allowed in the surfaces of the support body with a resonance frequency;
a plurality of laminated unit cells located inside the support body and respectively having electrodes, each of the plurality of unit cells being a thin-type laminated cell which has a smaller thickness thereof in a thickness direction, in which the electrodes are stacked, than thickness in other directions thereof, wherein
said top surface includes positive and negative battery terminals, and said unit cells are located between said opposing top and bottom surfaces and said opposing lateral surfaces of said support body; and
an opening portion provided in a plurality of the surfaces of the support body to be set at regions involving a loop position of the resonance in order to shift the resonance frequency to a higher frequency range, while communicating between an inside space in which the plurality of laminated unit cells are located and an outside of the support body, the opening portion being formed in at least one surface of the opposing top and bottom surfaces and the opposing lateral surfaces of the support body that is parallel to the thickness direction of each of the plurality of unit cells.
