1. 1. Investigating self-discharge in a graphite dual-ion cell using in-situ Raman spectroscopy.

   University essay from Uppsala universitet/Strukturkemi

   Author : Ismail Yussuf Hassan; [2023]
   Keywords : graphite; dual-ion battery; parasitic reaction; cathode-electrolyte interface; anion intercalation; concentrated electrolyte; self-discharge; Raman spectroscopy;

   Abstract : Anion intercalation in the graphite positive electrode of a dual-ion battery requires high potential (> 4.3 V vs Li+/Li), which aggravates parasitic reactions involving electrolyte decomposition and Al corrosion, manifesting in poor coulombic efficiency, cycle life, and quick self-discharge.

3. 2. Study on Lithium Battery Thermal Analysis For E-bike

   University essay from Högskolan i Halmstad

   Author : Sreekuttan Vijayan; Jais Jaimon; [2023]
   Keywords : Lithium-ion battery; e-bike; thermal analysis; forced convection cooling; natural air convection; temperature distribution; outlet ports; computational fluid dynamics;

   Abstract : E-bikes, often known as electric bicycles, are becoming more and more well-liked as green modes of mobility. High-capacity lithium-ion (Li-ion) batteries are utilised to power these e-bikes because of their extended cycle life, high energy density, and low self-discharge rate. READ MORE

4. 3. Accelerated Testing of the End-plate Assembly of a Redox Flow Battery

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Saksham Jindal; [2022]
   Keywords : Energy Storage; Flow Batteries; Accelerated Testing; Contact Resistance; Endplate Assembly; Leak Rate; Stack Design; Energilagring; flödesbatterier; accelererad provning; kontaktmotstånd; montering av ändplattor; läckagehastighet; utformning av staplar.;

   Abstract : As the world transitions to intermittent renewable energy sources like solar and wind, the need for long-duration energy storage technologies is becoming more and more prominent. In this regard, flow batteries are seen as a promising solution, owing to their inherent advantages like decoupling of power and energy, extremely high cycle life and negligible self-discharge.

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

   University essay from Lunds universitet/Kemiteknik (CI)

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

   Abstract : 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).
