Definitions
- the present invention relates to a flexible thread battery and a flexible thread battery with a connector.
- Patent Document 1 discloses an internal electrode composed of an internal current collector and a negative electrode material coated on the peripheral surface of the internal current collector, an electrolyte provided outside the internal electrode, and a peripheral surface of the electrolyte. Also disclosed is a thread-shaped battery which is composed of a positive electrode material and an external current collector and a protective coating portion provided on the peripheral surface of the positive electrode material and which can be deformed into various shapes.
- Patent Document 1 does not disclose any specific method for drawing an electric current from a thread type battery to the outside. Further, in the thread-type battery disclosed in Patent Document 1, since the internal current collector is present inside the battery, the position where the current can be drawn is fixed, and the degree of freedom of the extraction position of the external electrode is high. There was a problem of being low. In addition, Patent Document 1 discloses that the battery can be deformed into various shapes, but when a sulfide-based solid electrolyte is used as the electrolyte, the flexibility is insufficient, and the solid electrolyte is deformed during deformation. There was a problem that the battery was destroyed and the battery function stopped.
