A highly stretchable conductive glue that functions both as binder and as conductive additive in Si anodes is reported by Yinhua Zhou, Kaifu Huo, and co‐workers in article number 1704858. Lithium‐ion batteries applying this anode exhibit high cycling stability, large reversible capacity, and high initial coulombic efficiency, making the approach promising for next‐generation batteries.
Binder plays a key role in maintaining the mechanical integrity of electrodes in lithium‐ion batteries. However, the existing binders typically exhibit poor stretchability or low conductivity at large strains, which are not suitable for high‐capacity silicon (Si)‐based anodes undergoing severe volume changes during cycling. Herein, a novel stretchable conductive glue (CG) polymer that possesses inherent...
