Nanoporous Si@Carbon: Porosity‐ and Graphitization‐Controlled Fabrication of Nanoporous Silicon@Carbon for Lithium Storage and Its Conjugation with MXene for Lithium‐Metal Anode (Adv. Funct. Mater. 9/2020)

In article number 1908721, Jinkui Feng and co-workers fabricate uniform nanoporous silicon@carbon (NPSi@C) from commercial alloy and CO2 is fabricated as the anode for lithium ion batteries. The porosity of Si, graphitization degree, and thickness of carbon can be controlled by adjusting the reaction conditions. Moreover, a 2D/3D structure is designed by combining MXene and NPSi@C. As lithiophilic nucleation seeds for the Li metal anode, NPSi@C induces uniform Li deposition with buffered volume expansion.
