Abstract:

This bimonthly review paper highlights 100 recent published papers on lithium batteries. We searched the Web of Science and found 1880 papers online from Aug. 1, 2017 to Sep. 30, 2017. 100 of them were selected to be highlighted. Layered oxide and spinel cathode materials are still under extensive investigations for the effects of structure evolution and modificationson their cycling property and thermal stability. Large efforts were devoted to Si、Sn and oxides based anode material for improving their cycling propeties with new preparation method. Their capacity fading mechnism is also analyzed. The cycling properties of metallic lithium electrode are improved by designing current collector and surface cover layer. The studies of solid state electrolytes are focus on the method of preparation and the transport mechanism. Additives to liquid electrolyte can help to improve the cell’s stability at elavated temperatures. There are a few papers related to Li/S battery, Li-air battery for improving their cycling performance and more papers related to cell analyses, theoretical simulations, and modeling.

Key words: lithium batteries, cathode material, anode material, electrolyte, battery technology
