具有用于锂离子电池的精确膨胀空隙控制的Yolk-Shell Germanium@Polypyrrole架构
电化学测量
使用PGe @ PPy蛋黄 - 壳活性材料粉末与Super P炭黑和聚乙烯基二氟化物(PVDF，Kynar HSV 900)混合，重量比为80：10：10，在N-甲基吡咯烷酮(NMP)溶剂中用于生产 电极浆料。 将这些混合物用分散系统(Dissolver Dispermat CA40，VMA-Getzmann GmbH，Germany)进一步搅拌和均化约2小时。 最后，将浆液在真空下脱气1小时以除去气泡。将阳极浆料浇铸在铜箔上。 通过改变刮刀高度来制备不同厚度的阳极。 将涂覆的电极在110℃的烘箱中在真空下干燥12小时。”
Electrochemical Measurements
The PGe@PPy yolk-shell active material powder and mixed with Super P carbon black and polyvinyldifluoride (PVDF, Kynar HSV 900), with a weight ratio of 80: 10:10, in N-Methylpyrrolidone (NMP) solvent was used to produce an electrode slurry. These mixtures were further stirred and homogenized with a dispersing system (Dissolver Dispermat CA40, VMA-Getzmann GmbH, Germany) for approximately 2h. Finally, the slurries were deaerated under vacuum for 1 h to remove the bubbles.The anode slurry was casted on copper foil. Anodes of different thicknesses were prepared by varying the doctor blade height. The coated electrodes were dried in an oven 110 oC under vacuum for 12 h.”
