dc.description.abstract | It is important to increase the energy density of olivine-type cathode materials utilizing micro-sized particles for rechargeable lithium batteries. However, according to the literature, micro-sized LiMn1-xFexPO4 compounds have limited specific capacity because they exhibit lower electrical conductivity than nano-sized materials: isolation of the inner part of the particles from the electrolyte results in an electrochemically inactive area during cycling, which hinders proper Li+ transport that causes the failure of the micron-sized particles. To improve the electrical conductivity of micro-sized LiMn1-xFexPO4, we designated micro-sized C-LiMn0.5Fe0.5PO4 materials composed of nanopores in the micro-sized particles synthesized via co-precipitation. The resulting morphology was spherical, showing a tap density of 1.27 g cm(-3), and uniform carbon coating layers on the primary particles with nanopores were observed in the secondary particles. The as-synthesized micro-sized C-LiMn0.5Fe0.5PO4 exhibited outstanding cyclability at a C-rate of 0.5, retaining 97% of its capacity at room temperature and 85% at 55 degrees C, due to the synergetic effect of the presence of a uniform carbon coating layer on the primary particles with nanopores in the secondary particles. | - |
