Nickel oxide and yttria doped zirconia composite strength is crucial for anode-supported solid oxide fuel cells, especially during transient operation, but also for the initial stacking process, where cell curvature after sintering can cause problems. This ...
Similar to alane in alanates, borane species are assumed to be the mass transport intermediate in the hydrogen storage reaction MH + B + 3/2H2 MBH4 with M = Li and Na. One possible substep of this reaction is the interaction of diborane with the alkali hyd ...
Nanoporous materials provide exciting opportunities for improving the performance of electrochem. energy-storage devices such as pseudocapacitors and batteries. By producing materials with controlled porosity and high surface area, systems can be optimized ...
The local structure of TiBC and amorphous carbon (a-C) nanocomposite films (TiBC/a-C) was correlated with their optical and electrical properties. TiBC/a-C films with increasing C content were deposited by magnetron co-sputtering from TiC:TiB2 (60: 40) and ...
This paper proposes a new experimental investigation of the ageing mechanisms of super capacitors. Starting from the main ageing mechanisms of these devices reported in the literature, the paper proposes a suitably developed procedure aimed at evaluating t ...
As reliable mobile energy sources became more and more needed and alternative energy demands became more prevalent, the research in advanced energy storage technologies turned into a topic of utmost importance in today's society. Innovative electrode mater ...
The paper presents a set of experimental investigations related to the study of the dynamic behavior of supercapacitors. The experimentally-inferred results are then used as inputs for an improved version of one of the most common supercapacitor RC-circuit ...
Block-copolymer templating of inorg. frameworks provides a powerful route to produce periodic nanoporous materials with well-defined nanoscale architectures, controlled porosity, and high surface area. Such control is important for batteries and pseudocapa ...
In the domain of energy storage, electrochemical capacitors have numerous applications ranging from hybrid vehicles to consumer electronics, with very high power density at the cost of relatively low energy storage. Here, we report an approach that uses ve ...
