Oxocarbon Organic Conjugated Compounds for Lithium-ion Batteries and Solar Cells: Progress and Perspectives

Abstract

In recent years, with the continuous depletion of traditional fossil energy, the research of new energy storage materials has become one of the important ways to solve the issue of energy depletion. Generally, in an energy storage system, lithium-ion battery (LIB) has been widely applied in electronic intelligent devices and electrical vehicles (EVs). In an energy conversion system, as the most promising green energy system, solar cells have become a hot research field for scientists. Most recently, oxocarbon organic conjugated compounds (OOCCs) have been widely used in LIBs and solar cells due to their advantages such as abundant raw materials, environmental friendliness and high efficiency. As in this paper, the research progress of LIBs and solar cells based on OOCCs is reviewed, the synthesis strategies of these organic energy storage/conversion materials are summarized and the future research direction of organic energy materials is also prospected.
