Abstract: A button battery and a manufacturing method thereof are provided. The button battery includes a housing with a positive electrode shell and a negative electrode shell, wherein a plurality of positive electrode plates and a plurality of negative electrode plates are provided in the housing. The positive electrode plates and negative electrode plates are stacked at intervals to form a columnar cell. The positive electrode plates and the negative electrode plates are connected to the positive electrode shell and the negative electrode shell through a current collector respectively.
