A flexible electronic system includes a flexible electronic substrate having a first and second contact pads opposed to each other, one of the first and second contact pads is electrically coupled to a battery. A protective cover is disposed on the flexible electronic substrate. The flexible electronic system further includes a base support fixedly attached to the flexible electronic substrate, the base support having an adhesive surface opposed to the flexible electronic substrate, and a foil having a first portion removably coupled to at least a portion of the adhesive surface and a second portion, wherein the foil configures to permit a removal of the second portion disposed between the first and second contact pads and wherein the removal of the second portion activates the system.

Disclosed herein is a sheet attachment device for battery packs, specifically a sheet attachment device for attaching a label sheet and a sheathing sheet to a battery pack having a plate-shaped battery cell mounted in a pack case. The sheet attachment device includes first and second loaders, first and second jigs, first and second guide frames, a first sheet attachment jig, a rotator, a pressing roller, a conveyor, and a second sheet attachment jig.

A battery cover including a main body, an opening/closing part provided on the main body, a flexible rib having a locking projection provided on the opening/closing part, an abutting rib provided on the main body, which has a locking recess to be engaged with the locking projection while the opening/closing part is opened to the main body, a contact portion that abuts on the locking projection and deflects the flexible rib when the opening/closing part is opened to the main body, and a flat portion provided on the contact portion, which abuts on the locking projection first when the opening/closing part is opened to the main body and extends in the direction orthogonal to the direction of force input when abutting on the locking projection.

Provided is a battery module enabling accurate cutting of a bus bar without damage to secondary batteries. A battery module disclosed here includes a plurality of secondary batteries, and a bus bar electrically connecting the secondary batteries. Each of the secondary batteries includes a battery case. The battery module is provided with information on a cut position of the bus bar in disassembling the battery module.

A battery pack includes: a battery having a main surface; and a resin layer capable of being integrated with an armor member armoring the battery so that at least a part of the main surface of the battery is exposed and covering the main surface of the battery, wherein the resin layer is formed by curing a reaction curable resin having a viscosity of not less than 80 mPa.Math.second to less than 1000 mPa.Math.second and a thickness of the resin layer on the main surface of the battery ranges from 0.05 mm to smaller than 0.4 mm.

A battery terminal cover (1) is mounted on a battery (2) to be installed in a vehicle and includes a body (10) to be fixed to the battery (2), a movable portion (20) coupled to the body (10) via hinges (50) and rotatably displaceable to a shielding position to cover a screw member bolt (6) mounted on the battery (2) and an open position to be overlapped on the body portion (10), and a tool restricting portion (30) provided on the movable portion (20) and configured to restrict the rotation of a tool (T) by interfering with the tool before the tool rotated about the screw member (6) contacts the vehicle with the movable portion (20) set at the open position.

The disclosed technology relates to a battery utilizing an indicator to orient an unopposed portion of a cathode or anode with respect to a battery can, and a tag to generate an electromagnetic field to mitigate or eliminate an electromagnetic field generated by the unopposed portion of the cathode or anode. The battery includes a wound set of layers including a cathode, an anode, and a separator; a can housing the wound set of layers; a lid disposed atop of the can to enclose the wound set of layers within the can; and a tag coupled to the lid. An unopposed portion of the cathode or anode generates a first electromagnetic field. The tag generates a second electromagnetic field to oppose the first electromagnetic field.
