Developing conductive polymer binders is a new way to enhance the electric connectivity and mechanical contact of Si based anode material. While the linear structure of commercial PEDOT:PSS cannot effectively alleviate the volume expansion of Si. Herein, glycerol was introduced as a cross-linker to PEDOT:PSS binder for Si anodes, which can further improve the interfacial compatibility between silicon and PEDOT:PSS. After crosslinking, the peel force increased 2 times. As a result, the Si nanoparticles anode with the glycerol-crosslinked binder exhibited a high reversible capacity of 1951.5 mAh g-1 after 200 cycles at 0.5 A g-1 and superior rate capability (804 mAh g-1 at a high current of 8.0 A g-1) for the inherent superior conductivity of PEDOT:PSS.

甘油交联的PEDOT：PSS作为用于Si阳极的双功能粘合剂：改善了界面相容性和导电性。

开发导电聚合物粘合剂是增强硅基阳极材料的电连接性和机械接触的新方法。虽然商用PEDOT：PSS的线性结构无法有效缓解Si的体积膨胀。在此，将甘油作为交联剂引入到用于硅阳极的PEDOT：PSS粘合剂中，这可以进一步改善硅与PEDOT：PSS之间的界面相容性。交联后，剥离力增加了2倍。结果，具有甘油交联粘合剂的Si纳米颗粒阳极在0.5 A g-1的200次循环后显示出1951.5 mAh g-1的高可逆容量，以及优异的倍率能力（在8.0的高电流下为804 mAh g-1 g-1）代表了PEDOT：PSS固有的优越导电性。
