一体成型の充電式電池およびその製造方法

Japanese Patent JP6967618

B2

The present invention discloses an integrally-formed rechargeable battery and a production method thereof. The integrally-formed rechargeable battery includes an integrally-formed metal sleeve, which serves as a negative electrode conductor of the lithium battery. The integrally-formed metal sleeve is a cylindrical case, an end surface of one side of the integrally-formed metal sleeve is of a closed structure, and an end surface of the other side of the integrally-formed metal sleeve is an annular portion with a hole in the middle. A cell assembly is installed within the integrally-formed metal sleeve. The cell assembly includes a cell, a circuit board, an exposed charging interface and a positive electrode conductor. The positive electrode conductor is exposed from the hole in the middle of the annular portion. According to the integrally-formed rechargeable battery and the production method thereof of the present invention, by providing the integrally-formed metal sleeve with end surfaces at two ends, the cell assembly is surrounded therein, in this way, the integrally-formed rechargeable battery has a smooth appearance, and enables the overall structure of the lithium battery to be reliable. The cell assembly will not loosen, and two ends of the metal sleeve have no burrs. Accordingly, no damage to an outer film of the battery or no scratch to a user will be caused.
