Abstract
A rechargeable battery having a compact size and improved strength comprises a case, a battery cell, a circuit board and a covering member. The case has an internal space and an open end. The battery cell is made of a pliable material and is installed within the case, wherein a surface of the battery cell is electrically connected to the circuit board at the open end of the case. The covering member hermetically seals the open end of the case. Accordingly, the battery has a compact size, improved strength and may be manufactured easily.
Claims24
A rechargeable battery comprising:
- a case having an internal space and an open end;
- a battery cell installed within the case, the battery cell made of pliable material and having a surface electrically connected to a circuit board at the open end of the case;
- and
- a covering member for hermetically sealing the open end of the case, the covering member enveloping said surface of the battery cell electrically connected to the circuit board,
- wherein the covering member is injection molded to the open end of the case including an inner surface of the case, such than an air gap is formed between an inner surface of the covering member and the battery cell with a predetermined distance,
- and wherein the circuit board is installed at an interval from the case and protrudes outside the case such that the circuit board does not block the open end of the case during the injection molding process.
