Metal oxide-mixed polymer-based hybrid electrochromic supercapacitor: improved efficiency and dual band switching

“…Therefore, employing P3HT and WO 3 in an ECD will enhance the overall performance of the device. To make the ECD supercapacitive, several energy storage materials were explored [27,40]. The inclusion of pseudocapacitive-type supercapacitor materials appears to be a better option for increasing the ECD performance and adding charge storage capability, as pseudocapacitors store charge using a redox mechanism.…”

Utilizing rare earth titanates to improve performance of solid-state electrochromic device

“…Electrochromic devices have attracted massive attention due to their ability to modulate optical properties under the application of external bias [1,2] and its substantial application in smart windows [3,4], sensors [5,6], charge storage indicators [7,8], energy-efficient buildings [9,10], and automobile industry [11], etc. Various electrochromic materials have been discovered over the past few decades, broadly categorized as organic materials [12], inorganic materials [13], organometallics [14], metal-organic frameworks (MOFs) [15], polymers [16], and metal complexes [17].…”

A supercapacitive all-inorganic nano metal–oxide complex: a 180° super-bendable asymmetric energy storage device

“…Supercapacitors with extreme flexibility and bending characteristics having high electrochemical energy storage properties such as high capacitance, long cycle life, and small size are more suitable for applications in supercapacitor industries in the future for multi-functional purposes. 16–20 The major problem with flexible supercapacitor devices is their poor electrochemical performance, leakage of electrolyte, and low specific capacitance under mechanical deformation and different bending angles. 18,21,22 Mostly, flexible supercapacitors are fabricated from carbonaceous materials such as graphene, carbon-based fiber flakes and carbon paper, resulting in EDLC-type device performance having low energy density.…”
