    摘要： A drawable adhesive tape and a drawable adhesive tape product. The drawable adhesive tape includes: a base framework extending along length direction of the drawable adhesive tape and having a plurality of adhesive-accommodating regions which extend along both thickness direction of the drawable adhesive tape toward interior of the base framework and length direction of the drawable adhesive tape and which are arranged at intervals along width direction of the drawable adhesive tape, and an adhesive layer filled in the adhesive-accommodating regions. The drawable adhesive tape product includes a release paper and the drawable adhesive tape, in which, a surface of the drawable adhesive tape where the adhesive-accommodating regions are located is covered by an oily surface of the release paper. The drawable adhesive tape and drawable adhesive tape product have improved tensile strength and improved adhesion strength.

    摘要： A battery including a negative electrode active material layer, a positive electrode active material layer and a separator. In a first direction, the positive electrode active material layer includes a first portion and a second portion connected to the first portion. The second portion includes a first end, and the first portion includes a first surface. The first surface is connected to the second portion through a first connection, the first end is away from the first connection and is an end of the positive electrode active material layer, and a thickness of the second portion in a second direction perpendicular to the first direction decreases from the first connection to the first end in the first direction.

    摘要： A battery for powering a wearable device comprises a first cell, a second cell interconnected with the first cell, and a connection electrically coupled between the first cell and the second cell. The connection extends from the first cell to the second cell along a first direction. A length of the connection along the first direction is greater than a distance between the first cell and the second cell. In some embodiments, the connection comprises a folded structure configured to accommodate a dimensional change of the battery when bending the wearable device.
