The X-ray diffraction pattern shows that LiCoPO4 has a well developed orthorhombic structure with Prima space group The SEM analysis shows the particulate nature of the prepared materials with <200 nm size. The TEM analysis confirms that a 2-3 nm thick LiFePO4 layer is coated onto LiCoPO4. The LiFePO4 coated LiCoPO4 cell delivers a high initial discharge capacity of 132 mAhg(-1), which is 19 mAhg(-1) higher than the parent LiCoPO4 Furthermore, the LiFePO4 coated LiCoPO4 cell exhibits an improved capacity retention compared to the original LiCoPO4 during cycling Crown Copyright (C) 2010 Published by Elsevier B V.
