Leveler containing two quaternary ammonium salts allows for the galvanostatic bottom-up filling. In addition, the filling time is reduced by applying the step current comprising a first step to establish a growing surface and a second step to reduce the filling time. The deposition height of the growing surface during the first step critically determines the filling performance. By modulating the step condition, the filling time reduced by 47% compared to the constant current deposition. © The Author(s) 2015. Published by ECS.

The silicon nanotube thin film samples with thicknesses ranging from 10‐28 microns were prepared using silicon deposition on bulk produced zinc oxide nanowire films and subsequent removal of zinc oxide cores. The developed silicon nanostructures exhibit tubular geometry with both open ends. The nanotubes with thin walls are shown to accommodate large volume changes with lithiation and exhibit stable capacity retention. The presence of hydrogenated nanocrystalline silicon (nc-Si:H) is shown to be essential for the silicon nanotube thin film performance for lithium ion battery applications. © The Author(s) 2015.

Self-discharge processes can be tested in a loadfree state for a fixed time. Two self-discharge reactions are possible in a Li-ion cell: one is chemical and the other electrochemical. Because of their reactivity, charged cells can undergo side reactions, and factors such as purity of the active material or electrolyte, the specific surface area of the electrodes, conductors, binders or separators can have effect on the self-discharge performance. These reactions are mostly irreversible while electrochemical reactions can be reversible.
