Conversion reactions for sodium-ion batteries
Klein, Franziska; Jache, Birte; Bhide, Amrtha; Adelhelm, Philipp (2013)Research on sodium-ion batteries has recently been rediscovered and is currently mainly focused on finding suitable electrode materials that enable cell reactions of high energy densities combined with low cost. Naturally, ... -
The impact of carbon materials on the hydrogen storage properties of light metal hydrides
Adelhelm, Philipp; De Jongh, Petra E. (2011)The safe and efficient storage of hydrogen is still one of the remaining challenges towards fuel cell powered cars. Metal hydrides are a promising class of materials as they allow the storage of large amounts of hydrogen ... -
Room-temperature sodium-ion batteries : Improving the rate capability of carbon anode materials by templating strategies
Wenzel, Sebastian; Hara, Takeshi; Janek, Jürgen; Adelhelm, Philipp (2011)Current kinetic limitations of carbon anode materials in sodium-ion batteries can be effectively tackled by using tailor-made carbon materials with hierarchical porosity prepared via the nanocasting route. Capacities ... -
Towards commercial products by nanocasting : characterization and lithium insertion properties of carbons with a macroporous, interconnected pore structure
Jache, Birte; Neumann, Christian; Becker, Jorg; Smarsly, Bernd M.; Adelhelm, Philipp (2012)Carbon materials with defined porosity are prepared using the nanocasting approach. The structural properties of the prepared carbon materials are examined by SEM, XRD, XPS, elemental analysis, nitrogen physisorption and ...
