    Abstract: An apparatus and method for determining electrode information of a battery including a positive electrode and a negative electrode, and a battery pack including the apparatus. The apparatus includes a sensing unit configured to measure a voltage and a current of the battery, and a processor. The processor generates a V-dQ/dV curve based on the voltage and the current of the battery. The V-dQ/dV curve indicates a relationship between V (the voltage of the battery) and dQ/dV (a ratio of an amount of change dQ of the remaining capacity to an amount of change dV of the voltage of the battery). The processor detects a plurality of feature points from the V-dQ/dV curve. The processor determines information associated with each of the first electrode and the second electrode as the electrode information based on the plurality of feature points.
