| 中文摘要 | novel epsilon-cu0.95v2o5 hollow microspheres assembled by single-crystalline nanoribbons can be easily synthesized directly from a hydrothermal reaction between v(iv)o(acac)(2) and cu(no3)(2) in a solution containing a proper amount of polymer polyvinyl pyrrolidone (pvp, k30). a possible growth mechanism has been proposed. electrochemical measurements demonstrate that the as-prepared epsilon-cu0.95v2o5 superstructures display a reversible capacity of 304 mah g(-1), and could sustain respectable rate capability. by reinvestigating the cooperative displacement/intercalation (cdi) mechanism of epsilon-cu0.95v2o5 using cyclic voltammetry (cv), ex situ xrd, and ex situ sem-eds techniques, it is found that the copper dissolution problem, which leads to poor capacity retention of cells operating on li-driven cu extrusion-insertion process, has not been well tackled due to its superstructure collapse. rational electrode configuration design is urgently needed. in addition, single-crystalline alpha-cuv2o6 nanograins are obtained by calcining the micro-nanostructured epsilon-cu0.95v2o5 precursor. the post-treated alpha-cuv2o6 exhibits high discharge capacity of 507 mah g(-1) at 20 ma g(-1) and 390 mah g(-1) at 80 ma g(-1), indicating it is a promising cathode candidate for long-term and high-rate lithium primary batteries.
