1. 1. Membrane evaluation and thermal modelling of the vanadium redox flow battery

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Anders Kronander; [2016]
   Nyckelord :thermodynamics; Thermal; Simulation; Energy storage solutions; Modelling; VRB; Vanadium; Battery; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

   Sammanfattning : In this study, different membranes were tested for their use in a vanadium redox flow battery (VRB). The membranes were first tested under charge-discharge operation of the VRB over four charge-discharge cycles at different current densities (20 mAcm-2, 40 mA cm-2 and 60 mAcm-2) and the corresponding cell performance was evaluated in terms of total energy efficiency (EE), coulombic efficiency (CE) and voltage efficiency (VE).

3. 2. Vanadium Redox Flow Battery : Sizing of VRB in electrified heavy construction equipment

   Master-uppsats, Mälardalens högskola/Framtidens energi

   Författare :Nathan Zimmerman; [2014]
   Nyckelord :All-vanadium redox flow battery; Vanadium; Energy storage; Batteries; Electric vehicle electrification;

   Sammanfattning : In an effort to reduce global emissions by electrifying vehicles and machines with internal combustion engines has led to the development of batteries that are more powerful and efficient than the common lead acid battery.  One of the most popular batteries being used for such an installation is lithium ion, but due to its short effective usable lifetime, charging time, and costs has driven researcher to other technologies to replace it.
