　　报告内容：The development of advanced battery technologies has been driven by the ever-increasing demand for more efficient energy storage. Lithium-ion (Li-ion) batteries have revolutionized the present information-rich and mobile society. However, the intrinsic intercalation mechanism of Li–ion batteries places an upper limit on their energy density due to the limited weight and volume of the cathode and the anode host for Li ion intercalation. Therefore, it has become an imperative to explore high-energy alternatives beyond the Li–ion intercalation electrochemistry. Advanced Li batteries, employing emerging high-capacity cathodes like sulfur and/or high-capacity anodes like Li metal, have been regarded as promising next-generation battery technologies to meet the future needs due to their high-energy-density advantage. Yet the uncontrolled electrochemical behaviors of these high-capacity electrodes have greatly hindered their practical implementation. Carbon materials, known with many appealing properties including high conductivity, tunable structure and surface chemistry, and light weight, are investigated intensively to improve the performance of advanced Li batteries. Here we showcase how carbon-based materials serve to regulate the electrochemical behavior of sulfur cathodes and Li metal anodes from the fundamental redox reactions to electrode structure and integral cell design, to achieve high-energy and highly stable lithium batteries. Important cell parameters that dictate the practical energy density of a Li battery will also be taken into consideration to pave the way for constructing high-energy batteries under realistic conditions.
