Carbon-coated LiFeBO3 is prepared by sol-gel method, and polyethylene glycol 6000 (PEG-6000) is chosen as carbon source. Compared with conventional solid-state method, the LiFeBO3/C nano-particles were obtained at a relatively lower temperature (500 °C). It was demonstrated that the prepared LiFeBO3 is a highly pure monoclinic structure with space group of C2/c, the primary particle size of the carbon-coated...
Carbon-coated LiCoBO3 (LiCoBO3/C) is prepared by sol-gel method and polyethylene glycol 6000 (PEG-6000) is chosen as carbon source. The LiCoBO3/C sample exhibits an initial discharge capacity of 76.7 mAh g−1 at 0.1 C, and it can deliver a discharge capacity of 65.9 mAh g−1 after 50 cycles, while the LiCoBO3 sample only presents a first discharge capacity of 34.3 and 16.8 mAh g−1 at the 50th cycle,...
Carbon-coated LiMnBO3/C is synthesized by a sol-gel method using polyethylene glycol 6000 (PEG-6000) as carbon source. The influences of different sintering temperatures on the crystal structure, morphology, and electrochemical performance of LiMnBO3/C composites are investigated. XRD results indicate that the samples consist of the monoclinic phase LiMnBO3 (m-LiMnBO3) and the hexagonal phase LiMnBO...
