摘要： Disclosed is an electronic device. The electronic device includes a battery, a charging part configured to be connectable to an external charging device to charge the battery, a memory, and a processor operatively connected to the charging part and the memory. The processor may determine whether the charging part is connected to the external charging device, determine whether the electronic device moves and/or electronic device usage time information of a user, and reduce a voltage at which the battery enters supplementary charging to a second voltage lower than a first voltage which corresponds to a value stored in the memory, based on whether the electronic device moves and/or the electronic device usage time information. In addition, it is possible to implement various other embodiments understood through the disclosure.

摘要： A battery according to various embodiments of the present disclosure may comprise: a negative-electrode substrate formed to have a first length in a first direction and to have a second length larger than the first length in a second direction, comprising the first coating portion being coated with a negative-electrode active material, and a first uncoated portion arranged adjacent to the first coating portion; a positive-electrode substrate formed to have a third length in the first direction and to have a fourth length larger than the third length in the second direction, comprising the second coating portion being arranged to face the negative-electrode substrate and coated with a positive-electrode active material, and a second uncoated portion arranged adjacent to the second coating portion; and a separator arranged between the negative-electrode substrate and the positive-electrode substrate. The first coating portion of the negative-electrode substrate and the second coating portion of the positive-electrode substrate may comprise multiple notches recessed from the outside to the inside thereof along the second direction and arranged at a designated interval so as to form a structure in which at least a part of a roll-shaped corner portion is cut, the corner portion being obtained by winding the negative-electrode substrate, the positive-electrode substrate, and the separator together.
