Embodiment Construction

[0053] Hereinafter, a secondary battery to which the present invention is applied will be described in detail with reference to the accompanying drawings. The secondary battery 1 to which the present invention is applied is, for example, a polymer lithium ion secondary battery, and, as Figure 1A with Figure 1B As shown, it can be used in various electronic devices such as the digital camera 10. Specifically, when the secondary battery 1 is accommodated in such as Figure 1A The secondary battery 1 supplies driving power to the digital camera 10 when the digital camera 10 is shown in the battery housing 12 provided inside the grip portion 11 . The battery accommodating portion 12 is constituted by a substantially planar concave portion corresponding to the shape of the secondary battery 1, and is oriented toward the External. Further, in the battery housing 12 , housing electrodes are formed at the bottom, which are in contact with electrode terminal parts 37 , 38 provide...

Abstract

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 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 and being faced outwardly are provided and which plugs the opening of the battery can, the battery cell being accommodated in the battery can upon being adhered onto an inner face thereof.

Description

[0001] Related Application Cross Reference [0002] The subject matter contained in the present invention is related to Japanese Patent Application JP2005-234937 filed in the Japan Patent Office on Aug. 12, 2005, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a secondary battery having an electrode body, which is housed in a package (pack) as an electric energy generating element, and the electric power generated by the electrode body can be output from the secondary battery through a pair of positive and negative electrode terminals, such as Lithium ion secondary batteries and lithium polymer secondary batteries. Background technique [0004] In recent years, there has been a rapid increase in demand for portable electronic devices including information devices such as notebook personal computers, mobile communication devices such as mobile phones, and video cameras. A sealed small secondary batt...
