Acidic or alkaline direct ethanol fuel cells (DEFCs) can be a sustainable alternative for power generation if they are fuelled with bio-ethanol. However, in order to keep the fuel cheap, ethanol has to be exempted from tax on spirits by denaturing. I

Mechanical modifications or harmful side reactions are undesirable ageing effects that can occur during cycling. These phenomena have a negative impact on cell performance and consequently limit cycling stability. The focus here is on investigations

Conversion/alloy active materials, such as ZnO, are one of the most promising candidates to replace graphite anodes in lithium-ion batteries. Besides a high specific capacity (qZnO = 987 mAh g-1), ZnO offers a high lithium-ion diffusion and fast reac

Li-S cells have a low voltage (about 2.1 V), but their potentially high energy density (200-500 Wh/kg) makes them a promising system for next generation batteries. To obtain high energy densities on cell level, the weight fraction and load of the act

Li-S cells are attractive due to their high potential gravimetric energy density, but they achieve only low cycle numbers. A major reason for this is a continuous electrolyte decomposition during cycling. As low electrolyte/sulfur ratios are required

Polymer electrolyte membrane fuel cells (PEMFCs) are considered to be almost market-ready for automotive applications. The main obstacles which decelerate a broad application arise from the high costs for the production of membrane electrode assembli
