In article number 1908721, Jinkui Feng and co‐workers fabricate uniform nanoporous silicon@carbon (NPSi@C) from commercial alloy and CO 2 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.
