Provided are a pack main body of a substantially rectangular parallelepiped shape in which a battery cell is embedded, and a terminal portion provided on a front face of the pack main body. The pack main body includes bevelled portions at corner portions formed by a top face and a bottom face and opposite side faces. The terminal portion is provided, in a protruding manner, on the front face at a position biased with respect to centre lines in a width direction and a height direction. The corner portions on one side have a chamfered shape and the corner portions on the other side have a rounded shape.

Battery pack

A secondary battery for an electronic appliance, including a battery cell. The battery cell has a positive electrode, a negative electrode, and an electrolyte in a pack. A positive electrode terminal and a negative electrode terminal are led out from the same side face of the pack. A metallic battery can accommodates the battery cell therein such that the side face from which the positive electrode terminal and the negative electrode terminal are lead out is faced towards the opening side. A lid, made of a synthetic resin, in which terminal parts to be connected to the electrodes of the electronic appliance upon being connected to the positive electrode terminal and the negative electrode terminal are faced outwardly, plugs the opening of the battery can, the battery cell being accommodated in the battery can upon being adhered onto an inner face thereof.

Secondary battery

A secondary battery for an electronic appliance, including a battery cell. The battery cell has a positive electrode, a negative electrode, and an electrolyte in a pack. A positive electrode terminal and a negative electrode terminal are lead out from the same side face of the pack. A metallic battery can accommodates the battery cell therein such that the side face from which the positive electrode terminal and the negative electrode terminal are lead out is faced towards the opening side. A lid, made of a synthetic resin, in which terminal parts to be connected to the electrodes of the electronic appliance upon being connected to the positive electrode terminal and the negative electrode terminal are faced outwardly, plugs the opening of the battery can, the battery cell being accommodated in the battery can upon being adhered onto an inner face thereof.

A secondary battery for electronic appliance to be accommodated in an electronic appliance, thereby feeding an electric power to the electronic appliance, is disclosed, which includes a battery cell in which a positive electrode, a negative electrode and an electrolyte are accommodated in a pack, and a positive electrode terminal and a negative electrode terminal from the positive electrode and the negative electrode, respectively are lead out from the same side face of the pack; a metallic battery can in which one opening from which the battery cell is inserted is formed and which accommodates the battery cell therein such that one side face from which the positive electrode terminal and the negative electrode terminal are lead out is faced towards the opening side; and a lid made of a synthetic resin in which a positive electrode terminal part and a negative electrode terminal part to be connected to the electrodes of the electronic appliance upon being connected to the positive electrode terminal and the negative electrode terminal and being faced outwardly are provided and which plugs the opening of the battery can, the battery cell being accommodated in the battery can while the positive electrode terminal and the negative electrode terminal being curved between the positive electrode terminal and the negative electrode terminal and the lid.

A secondary battery for electronic appliance to be installed in an electronic appliance, thereby feeding an electric power to the electronic appliance, is disclosed, which includes: a battery cell in which a positive electrode, a negative electrode and an electrolyte are accommodated in a pack, and a positive electrode terminal and a negative electrode terminal from the positive electrode and the negative electrode, respectively are lead out from the same side face of the pack; a metallic battery can in which one opening from which the battery cell is inserted is formed and which accommodates the battery cell therein such that the side face from which the positive electrode terminal and the negative electrode terminal are lead out is faced towards the opening side; and a lid made of a synthetic resin in which a positive electrode terminal part and a negative electrode terminal part to be connected to the electrodes of the electronic appliance upon being connected to the positive electrode terminal and the negative electrode terminal and being faced outwardly are provided and which plugs the opening of the battery can.

The present invention provides a battery including a case and a battery cell accommodated in the case. The case is divided in a thicknesswise direction of the battery cell into a first case and a second case. The first and second cases have joint portions formed along peripheries thereof for jointing with each other. The joint portion of one of the first and second cases has a joining thin wall formed to extend along a periphery thereof and project in the thicknesswise direction. The joint portion of the other of the first and second cases has a joining recess formed to extend along a periphery thereof for receiving the joining thin wall inserted therein in a state that the joint portions of the first and second cases joint with each other. The joining thin wall and the joining recess in which the joining thin wall is inserted while the joint portions of the first and second cases joint with each other are joined together by welding. The other case has a projecting wall formed at a location of an outer face thereof positioned on the outer side of the joining recess in such a manner as to extend along the joining recess.
