We report a strategic development of asymmetric (supercapacitive–pseudocapacitive) and hybrid (supercapacitive/pseudocapacitive–battery) energy device architectures as generation–II electrochemical energy systems. We derived performance-potential estimation regarding the specific power, specific energy, and fast charge–discharge cyclic capability. Among the conceived group, pseudocapacitor–battery hybrid device is constructed with...

The development of state-of-the-art gas sensors based on metal oxide semiconductors (MOS) to monitor hazardous and greenhouse gas (e.g., methane, CH4, and carbon dioxide, CO2) has been significantly advanced. Moreover, the morphological and topographical structures of MOSs have significantly influenced the gas sensors by means of surface catalytic activities. This work examines the impact of morphological and topological networked...

Deployment of two-dimensional layered materials beyond graphene, i.e., MXene (Ti3C2Tx, T=-OH, F, O) are rigorously explored for generation-II electrochemical energy storage systems. We report strategic development of asymmetric supercapacitors (ASCs) comprising MXene as negative and laser-induced porous graphene (LIPG) as positive electrode (i.e., MXene//LIPG) to improve electrochemical energy storage in lateral (coplanar) and...
