TL;DR: The macro-/mesoporous silicon shows significantly improved cyclic and rate performance over the commercial nanosized and micrometer-sized silicon particles and shows superior catalytic performance for photocatalytic hydrogen evolution compared to the silicon nanoparticles.

TL;DR: In this paper, a 3D hierarchical macro-mesoporous SiO2/C composite is proposed to improve the cyclic performance of the Si anodes by using a self-templating mechanism during the reduction process.

TL;DR: Super-small metal nanoparticles are in situ synthesized and homogeneously embedded in the in situ formed nitrogen-doped carbon matrix, as demonstrated by the Si/Ag/C nanohybrid, where epoxy resin monomers are used as solvent and carbon source, and shows superior rate performance compared to the bare Si/C sample.

TL;DR: The reversible specific capacity after 1000 cycles at 175 mA g-1 and rate performance at high current densities of the Li4Ti5O12/C nanohybrid have been significantly improved and enhanced electrochemical performance is due to the unique structure feature, where the supersmall LTO nanoparticles are homogeneously embedded in the continuous carbon matrix.

TL;DR: In this paper, a new concept has been developed to enhance the electrochemical performance of the Si nanoparticle anode, which is found to significantly improve the mechanical properties of the si electrode, leading to enhanced cyclic performance.
