In a battery including a battery cell formed in a flattened substantially parallelepiped shape and a terminal contacting section electrically connected to the battery cell, at one end in the longitudinal direction of a face of the battery opposing to the face on which the terminal contacting section is provided, a projecting portion which projects in the longitudinal direction of the face is provided. Meanwhile, another projecting portion which projects in the longitudinal direction of the face is provided at the other end. The projecting portions may have projecting lengths different from each other or may have projecting lengths and projecting thicknesses different from each other. A charging apparatus into which the battery is to be installed includes an accommodating section for the battery which in turn includes projection accommodating portions configured to individually accommodate the projecting portions.

Battery, charging apparatus and electronic device

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.

Secondary battery

In a battery () including a battery cell formed in a flattened substantially parallelepiped shape and a terminal contacting section () electrically connected to the battery cell, at one end in the longitudinal direction of a face of the battery opposing to the face on which the terminal contacting section () is provided, a projecting portion () which projects in the longitudinal direction of the face is provided. Meanwhile, another projecting portion () which projects in the longitudinal direction of the face is provided at the other end. The projecting portions () may have projecting lengths different from each other or may have projecting lengths and projecting thicknesses different from each other. A charging apparatus into which the battery () is to be installed includes an accommodating section () for the battery () which in turn includes projection accommodating portions (and) configured to individually accommodate the projecting portions (and). The accommodating section () includes a space for accommodating a battery (D,E) wherein the battery cell has a rectangular principal face and another space for accommodating another battery () wherein the battery cell has a substantially square principal face, and charging terminals serve as charging terminals not only for the battery () but also for the battery (D,E).
