The invention provides a battery monomer, an energy storage device and an electric vehicle. The single battery comprises a battery cell and a battery cell monitoring device, and the battery cell monitoring device comprises a sensor unit and a power supply unit. The sensor unit is located at the cathode and fixed on the surface of the cathode current collector. The cell supplies power to the sensor unit through the power supply unit. The sensor unit comprises a sensor module and a signal modulator, and the sensor module sends a cell parameter signal to the signal modulator through a signal line. The power supply unit supplies power to the sensor unit through the conductive circuit. And the signal circuit and the wire circuit are etching circuits etched on the surface of the negative electrode current collector. The cell monitoring device is fixed on the surface of the negative current collector, and the signal circuit and the wire circuit are etched on the surface of the negative current collector, so that the problem that the cell capacity is affected due to the fact that the cell monitoring device is too large in size and too complex in structure can be solved.
