A tunable hierarchical porous framework is fabricated to house the volumetric changes outputted by Si. The nSicPAN/cPAN electrodes only expand by 14.3% at full initial lithiation and remain within 23% expansion from its uncycled state after 20 cycles with remarkable cycling stability and high coulombic efficiencies in excess of 99.5%
