A Study on the System Configuration for the Flywheel Energy Storage Device to be Applied to the Railway System

Lee J-H., Korea Railroad Research Institute, KR

A system configuration to be applied to the railway system using flywheel energy storage system to store regenerative energy which is produced during the braking period of the train is presented. The proposed FESS (Flywheel [...]

Nanostructured Acetylcholinesterase (ACHE) Memristor/Memcapacitor Mimicks Brachyhypopomus Electric Fish’s Signal-Cloaking Behavior

Chen E.T., Thornton J., Advanced Biomimetic Sensors, Inc., US

The Brachyhypopomus Electric (BHE) fish is known for its signal-cloaking behavior that allows it to avoid predators by shifting its electroreceptive pulses from low frequency to less detectable high-frequency through a phase-delay “head-tail” Electric Organ [...]

MWCNTs/metal oxide nanocomposite as potential material for supercapacitors application in acidic and neutral media

Adekunle A.S., Ozoemena K.I., Agboola B.O., Ebenso E.E., North-West University, ZA

Carbon based supercapacitor electrodes have been attractive due to their high surface area and porous nature. Studies have shown that the carbon nanotube-metal oxide (CNT-MO) nanocomposite modified electrodes exhibited huge capacitive current in some electrolytes. [...]

Synthesis and characterization of (polypyrrole/carbon) nanotubes/metal oxide composites for application as supercapacitors

de Oliveira A.H.P., de Oliveira H.P., de Oliveira A.H.P., de Oliveira H.P., UNIVASF, BR

The development of eco-friendly technologies such as hybrid vehicles requires more efficient high power energy storage materials, viz. supercapacitors. As reported in our previous work, the association of polypyrrole and carbon derivatives (modified graphene oxide [...]

Electrochemical Characterization of Naxmo2 as Cathode Materials in Sodium Batteries

Nguyen V.H., Le M.L.P., Huynh L.T.N., Tran V.M., Vietnam National University - Ho Chi Minh City, VN

NaxMO2 with M = Mn and Co as cathode materials in sodium-ion batteries was synthesized by solid-state reaction at 600-850oC. The manganese precursors was MnO2 obtained from electrolysis of MnSO4, MnCO3 and Mn(OAc)2 solutions. The [...]

Assessing damage to graphite electrodes in bromine redox flow battery systems

Bistrikaa A.A., Brekkenb T.K.A., von Jouanneb A., Lernerc M.M., Yokochia A.F.T., NRGindependence, Oregon State University, US

A crucial metric in harvesting renewable and intermittent power resources is widely understood to be the ability to, and cost effectiveness of, storing energy. Large chemical systems, such as Redox Flow Batteries (RFBs), are a [...]

Seawater Flow Battery as Technology Platform

Schubert P.J., Fu Y., IUPUI, US

Grid-level storage of renewable energy using electrolytes from seawater is a platform technology with multiple byproducts and use-case scenarios. The core application is to provide load-leveling for intermittent sources such as wind and solar. Membranes [...]
