Li insertion proceeds, the surface area decreases and a critical surface area is
reached where the Li transportation no longer sustains the current and the cell
performance becomes diffusion-limited. Electrochemical intercalation was
limited to ~0.6 Li/formula unit, and a specic capacity of 100–110 mAh/g was
achieved. Wang etal. [43] reported the synthesis of 1D nanowires of LiFePO
4
by hydrothermal methods using ferrous sulphate, ammonium dihydrogen
phosphate and lithium hydroxide. These 1D nanowires had a diameter in
the range of few hundred nanometres and lengths extending a few ...
