A novel boron-doped porous carbon (BC) was prepared through a facile one step pyrolysis process by using citric acid monohydrate, boron acid, and sodium chloride hybrid as precursor. Based on the analysis of X-ray photoemission spectroscopy and Raman spectroscopy, three boron-doping species (BC3, BC2O, and BCO2) were doped in the carbon lattice. The BC2O and BCO2 can generate abundant extrinsic defects...
The poor electronic conductivity and low lithium-ion diffusion are the two major obstacles to the largely commercial application of LiFePO4 cathode material in power batteries. In order to improve the defects of LiFePO4, a novel carbon source polyacrylonitrile (PAN), which would form the hierarchical porous structure after carbonization, is fabricated and used. This work comes up with a simple and...
