“…As a result, a generic term 'supercapattery' (= supercapacitor + battery) was proposed to represent these EES hybrid devices that are different from either supercapacitors or rechargeable batteries in terms of fundamental principles and technological prospects. Since the generic term 'supercapattery' was initially proposed in an industrial EES project initiated in 2007, researchers have actively promoted its use, leading to its gradual recognition by the EES community [19][20][21][22][23][24]. Supercapatteries represent various hybrid EES devices that take advantage of both capacitive and non-capacitive Faradaic (or Nernstian) charge storage mechanisms at either the electrode material level or the device level.…”

The development of novel electrochemical energy storage (EES) technologies to enhance the performance of EES devices in terms of energy capacity, power capability and cycling life is urgently needed. To address this need, supercapatteries are being developed as innovative hybrid EES devices that can combine the merits of rechargeable batteries with the merits of supercapacitors into one device. Based on these developments, this review will present various aspects of supercapatteries ranging from charge storage mechanisms to material selection including electrode and electrolyte materials. In addition, strategies to pair different types of electrode materials will be discussed and proposed, including the bipolar stacking of multiple supercapattery cells internally connected in series to enhance the energy density of stacks by reducing the number of bipolar plates. Furthermore, challenges for this stack design will also be discussed together with recent progress on bipolar plates.
