Vanadium redox flow batteries are very promising technologies for large-scale, inter-seasonal energy storage. Tuning models from experimental data and estimating the state of charge is an important challenge this type devices. This work proposes a non-linear lumped parameter concentration model to describe that differentiates species concentrations in different system components allows compute ...

Reversible chemical delithiation/lithiation of LiFePO(4) was successfully demonstrated using ferrocene derivatives, based on which a novel energy storage system--the redox flow lithium-ion battery (RFLB), was devised by integrating the operation flexibility of a redox flow battery and high energy density of a lithium-ion battery. Distinct from the recent semi-solid lithium rechargeable flow bat...

Accurately characterizing the performance of an off-grid photovoltaic (PV) microgrid system can help ensure that the system is appropriately sized to reduce the reliance on supplemental power generation via diesel-fueled generators. However, deterministic models cannot account for the inherent variability of solar insolation, ambient temperature, initial battery charge, and electrical load. A M...
