The present application discloses a battery to alleviate the impact on the main body of the battery and for improving the safety performance of the battery. The battery comprises a package case and a circuit board, wherein the package case forms a first surface and a buffer member is arranged between the circuit board and the first surface. In the present application, the buffer member between the circuit board and the first surface may alleviate the force received on the first surface, thereby alleviating the impact on the electrode assembly of the battery, avoiding the damage of the positive and negative electrode plates and the short circuit caused by the contact between the positive and negative electrodes, and improving the safety of battery.

Battery

The present disclosure relates to a cell, a battery and an electronic device. The cell includes a first electrode sheet and a second electrode sheet. The first electrode sheet includes a first current collector. The second electrode sheet includes a second current collector. The second current collector includes a starting section and a first bending segment connected to the starting section. A current collector opposite to the starting section and the first bending segment is configured as the second current collector. Thus, the cell is not internally provided with an opposite region between the first current collector and the second current collector, which may enhance the energy density of the cell and improve the safety of the cell.

Cell, battery and electronic device

The present application provides a battery and an electronic device thereof. The battery comprises: a electrode assembly having at least one separator protrusion; a package bag for accommodating the electrode assembly; and a buffer layer arranged between the electrode assembly and the package bag; wherein the buffer layer is further arranged on the at least one separator protrusion. The purpose of the present application is to provide a battery and an electronic device thereof which are capable of improving the drop resistance performance of the battery and improving the safety performance of its use.
