摘要

Vanadium pentoxide (V2O5) has played important roles in lithium-ion batteries due to its unique crystalline structure. To assist researchers understanding the roles this material plays, a comprehensive and critical review is conducted based on about 250 publications. Here, we report basics and applications of micro-and nano-materials of V2O5 and V2O5-based composites. The comparative and statistical analysis leads to the discovery of several interesting phenomena. The V2O5 electrodes with two lithium ions have a favorable capacity performance with reversible phase formation. The excellent capacity retention is displayed in the V2O5 electrodes with one lithium ion inserted. In the case of three lithium ions insertion, it was found that the irreversible formation of the phase. in LixV(2)O(5) leads to its control. In addition, effects of additives on electrode performance, circuitry models of performance, as well as reaction routes are studied. Two unprecedented concepts of the "high capacity band" and "empirical total capacity retention" are proposed though the comprehensive statistical analysis of the reviewed data. This review provides a comprehensive collection of information of state-of-the-art and recent advancement in V2O5 and V2O5-based composite materials for electrodes. Researchers could use the information to design and develop advanced electrodes for future batteries.
