Borghols, W.J.H. (author)Upon nano-sizing of insertion compounds several significant changes in Li-insertion behavior have been observed for sizes below approximately 50 nm. Although the origins of the phenomena are interrelated, the changes can be divided in three main observations. (1) The formation of new phases, leading to enhanced reactivity and extended capacities...doctoral thesis 2010

Garcia-Tamayo, E. (author)The remarkable physicist Richard P. Feynman once said, more than fifty years ago: ”the principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done; but in practice, it has not been done because we are...doctoral thesis 2014

Verhoeven, V.W.J. (author)In April 1997 the program "Decentralized Production and Storage for Large-Scale Application of Renewable Energy" of the Delft Interfaculty Research Centre (DIOC) was launched. In this program various groups from several Faculties of the Delft University of Technology studied the feasibility of large scale application of renewable energy. Energy...doctoral thesis 2001

Shen, K. (author)Nanostructured materials are featured by providing a variety of favourable electrical properties, as the reduced ion and electron transport paths enable significant enhancement on (de)intercalation rates and hence high power. For TiO2 anatase, nano-sizing results in a curved open cell voltage profile with a much shorter plateau region in...doctoral thesis 2014

van Westering, W.H.P. (author)The volatility of renewable energy sources pose a significant challenge for Distribution Network Operators (DNOs) as it makes planning and maintaining a reliable electricity grid more complex. An essential tool in dealing with the uncertain behavior of renewable energy resources is the load flow simulation, i.e., the standard electricity network...doctoral thesis 2021

Schwietert, T.K. (author)Solid-state batteries have the promise to outperformconventional Li-ion batteries. Solid electrolytes are safer, as the solids used are generally not combustible, and especially if Li-metal anodes are enabled, higher energy densities can be obtained. However, solidstate batteries still have challenges to overcome. In this thesis the origins of...doctoral thesis 2022
