Synthesis of Porous Amorphous FePO4 Nanotubes and Their Lithium Storage Properties.

Holey pipes: An oil‐phase chemical route was used to prepare porous amorphous a‐FePO4 nanotubes. In the etching process, Fe2O3 reacted with weak acid, resulting in nanotubes with a pore size of 2–10 nm. The porous nanotubes show good cathode performance in lithium ion batteries owing to their hollow structure and small pore size. [ABSTRACT FROM AUTHOR]
