A battery module includes a unit module stack, in which unit modules, each of which includes one or more battery cells and a cell cartridge configured to receive the battery cells therein, are horizontally or vertically stacked on the basis of the ground; a pair of insulation sheets located at outermost sides of the unit module stack; and a pair of end plates located outside the pair of insulation sheets, wherein each of the pair of end plates is provided with a first protuberance protruding in a direction in which the unit module stack is located, and each of the pair of insulation sheets is provided with a first receiving portion configured to receive the first protuberance of a corresponding one of the end plates, the first receiving portion having an identical shape to the first protuberance, and a battery pack including the same.

Provided is a wearable patch that can reliably interrupt the power supply from the cell after use and can be disposed of as it is. Moreover, provided is a sheet-type cell that can reliably interrupt the power supply after use and can be disposed of safely. The wearable patch is worn on the body and includes a functional element, a drive circuit unit that operates the functional element, and a cell as a power source. A cutting facilitating member is formed to allow a predetermined portion of the wearable patch to be cut with a force of 200 N or less so that the power supply from the cell to the drive circuit unit is interrupted.

Embodiments described herein relate generally to electrochemical cells having semi-solid electrodes that are coated on only one side of a current collector. In some embodiments, an electrochemical cell includes a semi-solid positive electrode coated on only one side of a positive current collector and a semi-solid negative electrode coated on only one side of a negative current collector. A separator is disposed between the semi-solid positive electrode and the semi-solid negative electrode. At least one of the semi-solid positive electrode and the semi-solid negative electrode can have a thickness of at least about 250 μm.
