optimal sitting and sizing of shunt capacitor banks at the distribution networks for the purpose of power quality improvement is drawn much attention of electric power utilities in the last decades. determining the optimal number, location and sizing of capacitor using bee colony optimization algorithm (bco) is being presented in this paper. the bco algorithm is a new population based meta-heur...

The emerging wearable electronics integrated into textiles are posing new challenges both in materials and micro-fabrication strategies to produce textile-based energy storage power source micro-devices. In this regard, inkjet printing (IJP) offers unique features for rapid prototyping various thin-film (2D) devices. However, all-inkjet-printed capacitors were very rarely reported the literatur...

It has been shown that none of any energy sources which own high specific energy or high specific power, but not both, can solely fulfil all the demands of hybrid electric vehicle (HEV) in some circumstances. In this paper a simulation model for battery/ultra-capacitor hybrid energy storage system (B/UC HESS) was presented by Matlab/Simulink. Based on the model a low-pass filtering control stra...

The report provides a preliminary assessment of the charge storage prerogatives of an asymmetric electrochemical capacitor employing a carbon-grafted NiO electrode interfaced with 1-ethyl-3-methyl imidazoliumdicyanamide as an ionic liquid electrolyte. This configuration has been demonstrated to be potentially exploited for developing hybrid supercapacitors providing as high energy density as 21...

A capacitor-type cathode, made of a conducting polymer–carbon composite, and battery-type anode exhibit highly promising charge storage performance.

Lithium-Ion Capacitor In article number 2100029, Hui Sun, Qi Li, Zhibin Lei, and co-workers report the successful growth of KNb3O8 nanorods on conductive carbon cloth (CC) towards high-energy long-life lithium-ion capacitor. The short nanorods, enhanced conductivity negligible volume expansion during continuous charging/discharging process make one promising niobium-based anodes future charge s...

During the 1980s, a novel nonvolatile memory product was introduced, referred to as flash electrically erasable programmable read-only memory (EEPROM). The basic operating principle of the nonvolatile memory device is to store charges in the gate oxide of a metal-oxide semiconductor field-effect transistor (MOSFET). If charges can be stored in the oxide of a MOSFET, the threshold voltage of the...

Nanostructured devices have the potential to serve as the basis for next-generation energy systems that make use of densely packed interfaces and thin films. One approach to making such devices is to build multilayer structures of large area inside the open volume of a nanostructured template. Here, we report the use of atomic layer deposition to fabricate arrays of metal-insulator-metal nanoca...
