In Situ Construction of Binder-Free Stable Battery-Type Copper Cobaltite and Copper Oxide Composite Electrodes for All-Solid-State Asymmetric Supercapacitors: Cation Concentration and Morphology-Dependent Electrochemical Performance

“…are the emerging electrode materials for pseudocapacitors, and these types of materials have higher specific capacitances and energy densities than EDLCs. The electrochemical behavior of pseudocapacitive materials is shown by the near or deviated rectangular CV curves and almost linear or triangular GCD curves. , Others are battery-type SCs, where redox reactions occur in bulk materials by phase transformations and electrochemical reactions. , The current response is proportional to the square root of the scan rate in these materials . CuCo 2 O 4 and MnCo 2 O 4 are examples of battery-type supercapacitor materials (BTMs).…”

Temperature‐dependent synthesis of Mn 3 O 4 nanostructures by microwave irradiation method for high‐performance supercapacitors

“…The Nyquist plots show the real axis at a high‐frequency area, and a considerably weakened semicircle at the higher to mid, frequency area, and a linear part in the low‐frequency region 37‐38 . The RΩ indicated the bulk resistance,due to electrode and electrolyte, 22,39 and the charge transfer resistance (Rct) is represented by a semicircle at high frequency are, due to redox reaction between electrode and electrolyte interface. The linear part of the Nyquist plot corresponds to the Warburg diffusion ( Z w ) 40 .…”

The advent of membrane-less zinc-anode aqueous batteries with lithium battery-like voltage

“…5A), which is 41 V higher than that of their liquid counterparts. [28][29][30][31] We then manufactured a prototype version of the new high voltage membrane-less Zn|MnO 2 , shown in Fig. 5B.…”
