Porous silicon (Si)/carbon nanocomposites have been extensively explored as a promising anode material for high‐energy lithium (Li)‐ion batteries (LIBs). However, shrinking of the pores and sintering of Si in the nanoporous structure during fabrication often diminishes the full benefits of nanoporou...
