Micro-meso porous structured carbon nanofibers with ultra-high surface area and large supercapacitor electrode capacitance

, 2021
Carbon nanofibers from electrospun polymer nanofibers have received considerable attention. However, most of the carbon nanofibers with a surface area above 1000 m2/g were reported to have a supercapacitor electrode capacitance far below 350 F g−1 ...

Materials for energy storage: Review of electrode materials and methods of increasing capacitance for supercapacitors

Journal of Energy Storage, 2018
Supercapacitors (SCs) have shown great promise as a possible solution to the increasing world demand for efficient energy storage. Two types of mechanisms for SCs exist (double-layer and pseudocapacitive), and each type utilizes a wide variety of ...

Effect of the N/P/S and transition-metal co-doping on the quantum capacitance of supercapacitor electrodes based on mono- and multilayer graphene

, 2020
The effect of co-dopants (N, P, and S) and transition metals (TMs = Ti, V, Cr, Mn, Co, Ni) presence in mono- and multilayer graphene on the final material geometry, stability, electrical and magnetic properties, and quantum capacitance was systematically

Steep-slope hysteresis-free negative capacitance MoS2 transistors

Nature Nanotechnology, 2017
The so-called Boltzmann tyranny defines the fundamental thermionic limit of the subthreshold slope of a metal–oxide–semiconductor field-effect transistor (MOSFET) at 60 mV dec−1 at room temperature and therefore precludes lowering of the supply voltage ...
