چکیده انگلیسی
Nano porous materials LiFe0.75Mn0.25PO4/C were prepared by sol-gel method. The influences of sintering temperature on particle size, pore size distribution and cycling performance were studied. The results show that ratio of the mesopore in diameter 9.5ânm increases gradually with the increase of sintering temperature. The material sintered at 750â°C has high crystallinity, the particle size under 100ânm, the specific surface area of 80.3m2âgâ1, about 3ânm carbon coating, and higher ratio of the mesopore in diameter 9.5ânm. These are beneficial to the diffusion of lithium ion and the transfer of electrons, and high electrochemical performance material has been obtained. The initial discharge specific capacity is 120.28âmAhgâ1, it remains 80.71mAhgâ1 at 10C after 600 cycles.
