The Cover Feature illustrates a functional binder, in which multivalent Fe ions are coordinated by adjacent polymer chains (denoted by triangles). This architecture greatly enhances the cycle performance of Si microparticles; otherwise the particles break apart after several cycles. More information can be found in the Article by Seunghoon Nam, Byungwoo Park and co‐workers.

封面功能：用于高性能硅微粒阳极的金属配位介导聚丙烯酸酯（电池和超级电容器12/2020）

封面特征说明了一种功能性粘合剂，其中多价的Fe离子由相邻的聚合物链（由三角形表示）配位。这种结构极大地提高了硅微粒的循环性能。否则，粒子将在几个循环后破裂。有关更多信息，请参见Seunghoon Nam，Byungwoo Park及其同事的文章。
