“…The energy storage capacity of the supercapattery is calculated from GCD curves. The specific energy ( E ) and specific power ( P ) of the supercapattery are calculated by using the following relations 50 :

E = \frac{normalΔ V \times Q}{3.6 \times 2},

P = \frac{E \times 3600}{{Δ t}_{italicdis}} .

Here, Q represents specific capacity, Δt is the discharge time, and ΔV denotes the operating PW of the device. The supercapattery demonstrates excellent specific energy of 71.2 Wh kg −1 , with corresponding specific power, of 340 W kg −1 at 0.7 A g −1 , and a maximum specific power of 12 686 W kg −1 is attained at 14 A g −1 .…”

Summary The study divulges formation of nickel‐manganese phosphate and polyaniline (NiMn(PO4)2‐PANI)‐based ternary composites at different aspect ratios, synthesized via facile sonochemical method. The composite is utilized for high‐performance energy storage applications. The composite with 30 wt% PANI depicts the best electrochemical performance with maximum specific capacity (Qs) of 847 C g−1 at 0.5 A g−1 in three‐electrode assembly. The supercapattery device is assembled by utilizing NiMn(PO4)2‐PANI and activated carbon. The supercapattery demonstrates outstanding performance by delivering a remarkable specific energy of 71.3 Wh kg−1, and the maximum specific power is 12 686 W kg−1 and capacity retention of 97.6% after 5000 GCD series. Furthermore, the diffusive and capacitive mechanism is evaluated by applying Dunn's model. The b values are calculated to confirm the hybrid nature of the device. The study depicts the potentials of reported ternary composites as self‐supported electrode materials in the development of cost‐effective and efficient energy storage system.

Summary Supercapattery devices are currently gaining remarkable attention since they have the potential to meet the demand for high energy density with no constrain on power density, which is much higher in magnitude than supercapacitors and batteries. Nanomaterials based on metal oxides, phosphates, phosphides and sulfides are well utilized in the development and improvement of hybrid energy storage devices. Challenges facing nowadays by this technology, is to enhance the energy density with no compromise on the power density of the device. Merging the merits of the two technologies (supercapacitor and battery) in a single device will provide high specific power from the capacitive part while the battery counterpart overcomes the high energy concerns. In this review, we have focused our study on the recent progress regarding novel nanomaterials as an electrode material, comprising of high specific capacity and cyclic life, for state‐of‐the‐art supercapattery devices. Furthermore, this study may also enlighten the energy performance of the metal oxides, phosphates, phosphides, sulfides and nitrides as an excellent electrode material for high‐performance energy storage devices.
