Summary: Due to the urgent demand for high-energy-density lithium-ion batteries (LIBs), silicon (Si) with an ultrahigh capacity has gained wide attention. However, the practical application of Si is hindered by the large volume changes during cycling. In this study, a three-dimensional network binder composed of polyacrylic acid (PAA) and lysine (Lys) was constructed. The PAA/Lys binder exhibited strong adhesion to Si particles through hydrogen bonds and the cross-linked structure prevented irreversible slipping of PAA chains. The Si electrode using the PAA/Lys binder showed good cycling stability and high capacity retention, demonstrating the potential of using sustainable Si sources and environmentally friendly binders.

Summary: Fast ion diffusion in anode hosts is crucial for dendrite-free alkali-metal batteries. Expanding the interlayer spacing of anode materials is an effective strategy for Li diffusion, but not as efficient for Na and K. This study proposes a universal strategy to enhance the mass-transport efficiency of Na/K by introducing open mesochannels in carbon hosts. The modified carbon hosts enable uniform deposition of Na/K and stable dendrite-free cycling with outstanding rate performance.
