A battery is provided. The battery includes a battery enclosure that includes opposing top and bottom sides in a height direction, opposing left and right sides in a width direction, and opposing front and rear sides in a length direction. A first engaging portion extends in the length direction. A first lower surface is positioned on a plane between the top side and the bottom side in the height direction. A first rib is provided between a plane of the first engaging portion and the plane of the first lower surface in the height direction. A first upper surface is positioned on a plane between the top side and the bottom side in the height direction. A first wall is provided between the plane of the first lower surface and the plane of the first upper surface in the height direction.

Battery device, electronic apparatus, and battery system

Disclosed is a battery device including a battery enclosure incorporating a battery cell. The battery device further includes an output terminal that outputs power of the battery cell. The battery enclosure includes a first surface, a second surface, a first step surface, a second step surface, a first engaging portion, a second engaging portion, a first groove, and a second groove formed in the second step surface and the second engaging portion, and a recess is provided in at least one of the first step surface and the second step surface.

A battery apparatus including a case, a battery cell, a battery-side terminal, and an engaging piece. The case has a width, a thickness, and a length. The battery cell is housed in an inside of the case. The battery-side terminal is disposed on a side surface at one end of the case in a length direction and electrically connected to the battery cell. The engaging piece is disposed at the one end of the case at which the battery-side terminal is positioned such that the engaging piece extends in a length direction a same distance as the case at the one end portion. The engaging piece is at an edge of the case in a width direction.

Battery device and electronic apparatus

Erroneous insertion of a battery into an imaging device is prevented. In a battery loading and unloading mechanism, a battery is formed with projecting portions at longitudinal both ends of a back surface and along back surface, the back surface being a surface opposite to an insertion surface of the battery, whereby even the battery formed in a flat rectangular parallelepiped and having the almost-square main surface can be prevented from being erroneously inserted into the device. The projecting portion has an inclined surface acutely inclined with respect to the back surface, and when the battery is unloaded from the device, unloading of the battery from the device is accelerated by the inclined surface undergoing contact pressure of the retaining means.

Battery loading and unloading mechanism

Battery

A battery to hold a battery cell can include a first surface, an end surface forming a corner edge with the first surface along an edge of the first surface in a lateral direction, and an output terminal provided at the corner edge formed by the end surface and the first surface. The output terminal can include electrode slits that are opened to both the end surface and the first surface, and the electrode slits include electrodes to output power from the battery cell. First and second grooves can be provided in the first surface that extend away from the corner edge, where the output terminal is provided between the grooves in the lateral direction. Step surfaces can be provided that are stepped with respect to the first surface, and that include chamfered portions.

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

In a battery loading and unloading mechanism, a battery formed in a flat rectangular parallelepiped and having an almost square main surface is loaded and unloaded to and from a device. The battery is formed with projecting portions at longitudinal both ends of a back surface thereof and along the back surface, whereby the battery can be prevented from being erroneously inserted into the device. The projecting portion has an inclined surface acutely inclined with respect to the back surface, and when the battery is unloaded from the device, unloading of the battery from the device is accelerated by the inclined surface undergoing contact pressure of the retaining means. The device is formed with a notched portion which is adapted to expose the other projecting portion of the battery when the battery is loaded, thereby facilitating unloading of the battery.

A battery pack includes a battery housing, a battery cell having a tubular negative electrode having an opening part at one end and a positive electrode fixed to the negative electrode in such a way as to close the opening part, the battery cell being housed in the battery housing, and a protrusion disposed between the battery cell and the inner wall of the battery housing in an area other than an area where the positive electrode and the negative electrode of the battery cell are fixed.
