Ti-doped Li3V2(PO4)3/C cathode materials were synthesized by a novel sol-gel method with titanate coupling agent TC-Wt as a chelating agent, titanium and carbon sources.The effects of synthesis temperature and the amount of titanium on the crystal structure, morphology and electrochemical performances were investigated.The results show that Li3V1.95Tio.05(PO4)3 synthesized at 700℃ for 12h exhibits the optimal electrochemical performances.The improved electrochemical performances of the Ti-doped Li3V2(PO4)3/C cathode materials were attributed to the addition of Ti4+ ion by stabilizing the monoclinic structure.

当今社会的工业化规模制造中,无损检测技术已被广泛应用于航空、航海、航天、核电等领域用管的质量检验中,对确保产品质量起到了卓有成效的作用.然而,无损检测发展至今,已不仅仅是通常的"无损检查/无损检测/无损探伤"的含义了,其已发展到通过对记录的指示进行解释后的一种审查,以确定这些指示是否满足特定的验收准则阶段,即无损检测已向"无损评价"方向发展,为产品的质量控制提供有力的支持.
