Unleashing energy storage ability of aqueous battery electrolytes

Alkaline Benzoquinone Aqueous Flow Battery for LargeScale Storage of Electrical Energy

The replacement of fossil fuel energy with renewable sources has been increasing as the cost of solar and wind energy falls rapidly. Recent reports show that from 2008 to 2015, the cost of wind generation fell by 41%, rooftop solar photovoltaic installations by 54%, and utility-scale photovoltaic installations by 64%. The cost of solar panels now takes up less than 30% of a fully installed sola...

Conjugated polymer energy level shifts in lithium-ion battery electrolytes.

The ionization potentials (IPs) and electron affinities (EAs) of widely used conjugated polymers are evaluated by cyclic voltammetry (CV) in conventional electrochemical and lithium-ion battery media, and also by ultraviolet photoelectron spectroscopy (UPS) in vacuo. By comparing the data obtained in the different systems, it is found that the IPs of the conjugated polymer films determined by c...

Battery Storage for Supplementing Renewable Energy Systems

Battery energy storage can be integrated with renewable energy generation systems in either grid-connected or standalone applications. For stand-alone systems, batteries are essential to store electricity for use when the sun is not shining or when the wind is not blowing. For grid-connected systems, batteries add value to intermittent renewable resources by facilitating a better match between ...

Wind energy management with battery storage

This paper considers short-term energy management of a wind power plant with battery storage, in order to smooth the variations of power output to the external grid. An optimal on-line heuristic is developed for a control environment, in which decision-making is independent of wind historical data and forecasts.
