摘　　要：随着社会对大型储能设备的环保、充放电性能以及可持续发展的要求越来越高,基于金属氧化物的传统锂/钠离子电极材料受限于比容量,已难以满足未来储能系统的要求。有机材料、锂-硫/氧、液态流体等电池的研发与应用已成为未来能源系统研究的重要内容。其中,有机正极材料中的羰基类化合物Calix[4]quinone(C4Q)是一种很有前途的正极材料。该分子的空间位阻小,8个羰基结构都能发生可逆电极反应,其理论比容量高达446mA·h/g,远超传统无机电极材料。C4Q不仅可以作为储锂材料,也可作为钠、锌、镁等二次电池的电极材料。本文分别介绍了C4Q在锂、钠二次电池和锌水系电池中的应用成果,并对C4Q今后进一步的开发利用做了展望。It is urgent to develop environmental friendly and sustainable large energy storage devices with superior performances. Conventional lithium-ion batteries based on transition metal oxide limited by their low theoretical specific capacity and structure cannot meet the demand of future energy storage system. The development and application of new types of Li-organic materials, Li-S, Li-O2, flow battery and other batteries system will become the main focus of future energy systems. Especially, the conjugated carbonyl compounds with the merits of high theoretical capacity, flexible structure, fine redox property and green sustainability are potential energy storage materials for future. Calix[4] quinone (C28H16O8, C4Q) is a quinone derivative of Calix[4] arene, with a high theoretical capacity of 446 mA.h/g, which is significantly higher than that of traditional inorganic electrode materials. C4Q contains four p-quinone units linked by four methylene groups, the carbonyl groups are not sterically encumbered, hence the eight active centers are capable for reversible electrode reactions. Furthermore, the molecular structure of C4Q very stable and hardly decomposes in the electrochemical processes. More importantly, it is not limited to the reaction system theoretically by virtue of the electron transfer reaction, so it can be used as electrode materials for lithium, sodium, zinc and magnesium plasma batteries. In this paper, the applications of C4Q and its modification strategies are summarized.
