Silicon nanotube battery anodes.
We present Si nanotubes prepared by reductive decomposition of a silicon precursor in an alumina template and etching. These nanotubes show impressive results, which shows very high reversible charge capacity of 3247 mA h/g with Coulombic efficiency of 89%, and also demonstrate superior capacity retention even at 5C rate (=15 A/g). Furthermore, the capacity in a Li-ion full cell consisting of a...
متن کاملMultilayer High-Performance Ceramic Anodes
A new approach to the design of ceramic anodes that uses a thin catalytically active functional layer that has only modest electronic conductivity sandwiched between the electrolyte and a non-catalytic elecronically conducting ceramic layer that is used as the current collector is described. The anode design is flexible and allows various materials to be used in the functional and current colle...
متن کاملStacked porous tin phosphate nanodisk anodes.
Stacked porous octahedral tin phosphate Sn(2)P(2)O(7) nanodisks, with a thickness and a width of 20 nm and 200 nm, respectively, were prepared from quenching hydrothermally prepared (SnHPO(4))(2).H(2)O at 600 degrees C. The first discharge capacity was 600 mA h g(-1) while the capacity retention, even after 220 cycles, was 93%.
متن کاملPreparation of SOFC Anodes by Electrodeposition
Anodes for solid oxide fuel cells (SOFCs) have been prepared by electrodeposition of either Co or Ni into a layer of porous yttria-stabilized zirconia (YSZ), 60 μm thick. The YSZ, having 65% porosity, was prepared by tape casting with graphite pore formers and was attached to the dense YSZ electrolyte. After adding 10 vol % CeO2 by impregnation of aqueous solutions of CeNO3)3, followed by calci...
متن کاملStructured Silicon Anodes for Lithium Battery Applications
Pillar arrays fabricated on silicon substrates have been tested as potential anodes for lithium batteries. Electrodes of array characteristics, diameter 580 6 150 nm; fractional surface coverage 0.34; height 810 nm are reported here. Cyclic voltammetry ~CV! and cyclic galvanostatic tests of alloying/dealloying of electrochemically produced lithium with silicon were carried out, and results corr...
