Synthesis of cage-like LiFePO4/C microspheres for high performance lithium ion batteries

▸ Cage-like LiFePO4/C microspheres (cage-like LPCs) were synthesized. ▸ The unique structures offer cage-like LPC electrode with high rate performance. ▸ The microstructures of cage-like LPCs are very stable with a diameter of 1.6 μm. ▸ The reversible capacity of cage-like LPCs can maintain 160 mAh g−1 at 0.1 C. ▸ The reversible capacity of cage-like LPCs is as high as 120 mAh g−1 at 10 C.
