具有用于鋰離子電池的精確膨脹空隙控制的Yolk-Shell Germanium@Polypyrrole架構(gòu)
電化學(xué)測(cè)量
使用PGe @ PPy蛋黃 - 殼活性材料粉末與Super P炭黑和聚乙烯基二氟化物(PVDF，Kynar HSV 900)混合，重量比為80：10：10，在N-甲基吡咯烷酮(NMP)溶劑中用于生產(chǎn) 電極漿料。 將這些混合物用分散系統(tǒng)(Dissolver Dispermat CA40，VMA-Getzmann GmbH，Germany)進(jìn)一步攪拌和均化約2小時(shí)。 最后，將漿液在真空下脫氣1小時(shí)以除去氣泡。將陽(yáng)極漿料澆鑄在銅箔上。 通過(guò)改變刮刀高度來(lái)制備不同厚度的陽(yáng)極。 將涂覆的電極在110℃的烘箱中在真空下干燥12小時(shí)。”
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.”
