Silicon (Si) anode has been considered a promising candidate due to its remarkable theoretical capacity but it was plagued by severe pulverization because of the inherent huge volume variation. Enhancing electrode stability is an effective approach to improve electrochemical performance. Herein, a stable Si anode was established by an innovative construction of the bonding between conductive agents and active materials/binders. As a result, the strong interaction of electrode components not only effectively alleviates the volume expansion of Si but also achieves a stable interface by generating the beneficial solid electrolyte interphase (SEI) composition. Attributed to the deliberate scheme of the electrode, the Si anode exhibits sterling electrochemical performance. Besides, the device of the electrode is not only effective for other binders but also for other anode materials with high volume variation, thus shedding light on the rational design of electrodes for high-energy-density lithium-ion batteries.
