Department of Materials Science and Engineering, Southern University of Science and Technology, Shenzhen 518055, China © Central South University Press and Springer-Verlag GmbH Germany, part of Springer Nature 2019 Energy crisis and environmental pollution owing to the rapid consume of fossil fuel have become the two major challenges faced by human beings. Using the new energy, such as solar and wind energy to replace the fossil fuel, is a promising strategy to address the above issues. However, how to implement such new energy is still a big challenge. Developing chemical energy storage and conversion devices with high performance, low cost, long lifespan and high safety for wide applications has attracted tremendous attentions. The energy storage devices candidates include Li-ion batteries, Li-S batteries, Na-ion batteries, fuel cell, redox flow batteries and etc. In recent years, significant progresses have been made spanning from the fundamental studies to application-oriented prototypes in the field of energy storage and conversion. For this reason, we organize this special issue on “energy storage and conversion” in Journal of Central South University to show the latest advances in this field. This special issue collects 16 contributions, including 1 review and 15 articles. The topics cover different aspects in Li-ion batteries, Na-ion batteries, fuel cells, all-vanadium redox battery, Li-S battery and so on. Among these contributions, there are 10 papers focusing on the cathode materials (Sodium vanadate nanowire, Na2FePO4F/C, Li2FeSiO4/C/Ag, anthraquinone) and anode materials (Ce2Sn2O7 nanocubes, Sb@Sb2O3/reduced graphene oxide composite, manganese oxides, spherical tremella- like Sb2O3, anatase TiO2 ) for Li-ion batteries. Some emerging works on post Li-ion batteries are also covered. A Na0.44MnO2 nanorods/graphene composite was synthesized by LIU Li et al as a high performance cathode material for Na-ion batteries. LIU Yan-yan et al reported a bio-derived N-doped porous carbon as sulfur hosts for high performance lithium sulfur batteries. Three papers on electrochemical catalysis are also involved. In the review, ZHUANG Shu-xin reviewed the recent advances of the preparation and applications of perovskite-type oxides for electrocatalysis in oxygen/air electrodes. TANG You-gen and coworkers reported a red-blood-cell- like nitrogen-doped porous carbon as a highly efficient metal-free catalyst for oxygen reduction reaction. LIU Min and coworkers developed hierarchical TiO2 nanorods with a highly active surface for photocatalytic CO2 reduction. In addition, CHEN Yun-gui et al provided an anodic oxidation method to improve the electrochemical properties of carbon paper as negative electrode for vanadium redox battery. And LIU Fang et al proposed a SOC estimation strategy based on data driven EKF algorithm for power battery of EV and PHEV. In summary, these contributions present the cutting-edge researches in the field of energy storage and conversion. We would like to sincerely thank all the authors for their great efforts in preparing high-quality manuscripts. We also thank the professional editorial office of Journal of Central South University for their hard-works to make this issue such a great success.
