Chapter 1Introduction

Greiner, Simon

Pages: 1 –24

[Polyoxometalates (POMs) are anionic molecular metal oxides of early transition metals, mainly tungsten, molybdenum and vanadium, in their highest oxidation states with the general formula [MxOy]n–. They consist of polyhedral building blocks with the formula [MOz]m– (z = 4 - 7) which are...

Chapter 2Objective

Greiner, Simon

Pages: 25 –26

[Driven by the growing demand for high-performance batteries in mobile applications, electric vehicles as well as grid storage, novel electrode materials for LIB and Post-LIB technologies are required in the near and long-term future. Although current cathode materials offer high energy densities...

Chapter 3Results and Discussion

Greiner, Simon

Pages: 27 –74

[As mentioned in section 1.2.3, Li6[V10O28]·16H2O is decomposing during the standard electrode preparation. This could in part be due to the loss of the crystal water molecules, which stabilize the decavanadate units in the crystal structure via hydrogen bonds. Upon removal of the water molecules...

Chapter 4Conclusion

Greiner, Simon

Pages: 75 –79

[En route towards green and sustainable energy supplies as well as the demand for mobile devices require novel cathode materials with high capacity, stability, low cost and based on abundant materials. Polyoxovanadates with their high redox activity, low cost and weight and high abundance, are...

Chapter 5Experimental

Greiner, Simon

Pages: 81 –100

[Unless specified otherwise reagents and chemicals were supplied by Sigma Aldrich, Alfa Aesar, Merck and VWR in standard reagent grade quality. The materials were used without further purification. Unless noted otherwise, the reactions were carried out under ambient conditions.]
