Vanadium Oxide Nanostructures for Lithium Battery Applications

Lithium and Lithium-ion batteries for portable electronic devices and hybrid electric vehicles have gained great importance for energy storage today. However, how to prepare cathode materials with higher energy density, high potentials, and longer cycle life is still a challenge. Compared with commercial LiCoO2, vanadium oxides have higher specific capacity and interesting layered structures, w...

Vanadium-based nanostructure materials for secondary lithium battery applications.

Vanadium-based materials, such as V2O5, LiV3O8, VO2(B) and Li3V2(PO4)3 are compounds that share the characteristic of intercalation chemistry. Their layered or open frameworks allow facile ion movement through the interspaces, making them promising cathodes for LIB applications. To bypass bottlenecks occurring in the electrochemical performances of vanadium-based cathodes that derive from their...

Optimal Sizing of Vanadium Redox Flow Battery Systems for Residential Applications Based on Battery Electrochemical Characteristics

Abstract: The penetration of solar photovoltaic (PV) systems in residential areas contributes to the generation and usage of renewable energy. Despite its advantages, the PV system also creates problems caused by the intermittency of renewable energy. As suggested by researchers, such problems deteriorate the applicability of the PV system and have to be resolved by employing a battery energy s...

Simultaneous Control of Active and Reactive Powers of Vanadium Redox Flow Battery Systems in Flexible Microgrids

This paper discusses the control of flexible microgrids, consisting of a Redox Flow Batteries (RFB) and a new power conditioning system (PCS) for the RFB. Considering the importance of energy storage, this study is essential in power systems that are developed cautiously. RFB is connected to power system by a DC/DC or DC/AC converter to produce a DC voltage. It is very important that this conve...
