摘要：
Hierarchically porous silicon nanoflakes were synthesized from natural talc via a mechanochemical reduction method, which showed great potential in the scalable production of silicon nanoflakes due to the abundant precursor and facile strategy. The unique layered structure and chemical composition of talc enabled the formation of two-dimensional nanostructured silicon without any additional templates. As lithium-ion battery anodes, the silicon nanoflakes showed excellent electrochemical properties. We reported a facile, scalable, and cost-effective mechanochemical reduction strategy to synthesize hierarchically porous silicon nanoflakes with enhanced electrochemical performance from clay minerals.
