Battery with embedded circuits

The present invention relates to a battery with embedded circuits, including a battery unit, a control circuit layer, and packaging material. The battery unit is manufactured by a printed circuit board process. The control circuit layer is stacked with the battery unit to form a laminated structure, having at least: a circuit layer using the battery unit as a power source, and an electric contact layer electrically connected to the circuit layer. The electric contact layer has a plurality of electric contact points exposed outside the packaging material. The packaging material is for accommodating and sealing the battery unit and the control circuit layer.
