In recent years, the automotive industry has experienced a dramatic mutation in the develop ment of electric vehicles. One of the most important aspects of this type of vehicle is its thermal management. Among the various parts of an electric vehicle that are subjected to thermal management, the battery is of particular importance. Battery cell temperatures may exceed the allowable range due to...

The mentioned paper provides a new approach in the design, modeling and evaluation of vanadium redox flow batteries with polymer membrane. Vanadium redox flow batteries have been proposed as one of the advanced technologies in energy storage systems. This study is based on transient conditions of performance modeling of a battery cell. The proposed time-dependent model has developed based on co...

Storage of photovoltaic and wind electricity in batteries could solve the mismatch problem between the intermittent supply of these renewable resources and variable demand. Flow batteries permit more economical long-duration discharge than solid-electrode batteries by using liquid electrolytes stored outside of the battery. We report an alkaline flow battery based on redox-active organic molecu...

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...

The redox (Reduction-Oxidation) flow battery is one of the most promising rechargeable batteries due to its ability to average loads and output of power sources. The transient characteristics are well known as the remarkable feature of the battery. Then it can also compensate for a sudden voltage drop. The dynamics are governed by the chemical reactions, fluid flow, and electrical circuit of it...

The first model calculates how long changes to deep drainage take to appear as recharge to saline aquifers. The second models the groundwater flows to quantify how much saline groundwater will be delivered to the River Murray over a certain period of time. SIMRAT has influenced salinity policy development, delivered outputs required by policy and continually challenged our understanding of sali...
