A clean and sustainable energy supply is essential for the future of human beings and is thus a crucial issue in the 21st century. Regarding energy conversion and storage, lithium batteries have played an indispensable role over the past 20 years and will do so for the foreseeable future because of their advantages in energy density and cyclability. Nowadays, the lithium battery market, especially given the development of electric automobiles, has grown rapidly, and scientists are now urged to focus on not only energy density, but also power density, safety, and sustainability. Recently, Armand, Tarascon, and co-workers introduced the concept of a “sustainable battery” or “green battery”,[1–5] aiming to evoke researchers concern over the resource issues and environmental issues that may be caused by large-scale production and use of Liion batteries based on conventional inorganic electrodes. The key technique for a “sustainable Li-ion battery” is to develop renewable organic electrodes, which may eventually be synthesized from biomass.In fact, the concept of an organic electrode material is not new. Dichloroisocyanuric acid was studied as a cathode material for a lithium battery as early as the 1960s.[6] Some conducting polymers such as polyaniline and polypyrrole have already been commercialized.[7] However, relative to the application of organic materials in the field of light-emitting diodes (LEDs), photovoltaic (PV) devices, and field-effect transistors (FETs),[8] the development of organic electrode materials for rechargeable lithium batteries lags far behind. In the 1980s and 1990s, there was a search for organic polysulfide cathode materials.[7] However, this research diminished after 2000, because of their poor electrochemical performance and low stability. Recently, researchers have shifted their interest toward organic materials based on the carbonyl group, such as anhydrides and quinones, and achieved
