Microscopic pin-holder structures of β-Co(OH)2 having a feature of single crystal were synthesized through multistep crystal growth in an aqueous solution system. The hexagonal plates of the hydroxide were initially produced from an amorphous precursor. The parallel nanoscale pins of β-Co(OH)2 were then grown on the basal plates in the progressive stage. The single-crystalline array of LiCoO2 nanopins was obtained by topotactic transformation of the specifically shaped β-Co(OH) 2 pin holders.
