Three‐Dimensional Porous Core‐Shell Sn@Carbon Composite Anodes for High‐Performance Lithium‐Ion Battery Applications

Three‐Dimensional Porous Core‐Shell Sn@Carbon Composite Anodes for High‐Performance Lithium‐Ion... A three‐dimensional porous core‐shell Sn@carbon anode on nickel foam substrate was fabricated by electrostatic spray deposition (ESD) technique followed by high temperature treatment. The carbon shell with a thickness of about 3.2 nm was formed on porous Sn structure at high temperature. 3D porous structure and carbon shell were designed to buffer volume expansion/shrinkage of Sn lattice upon cycling and increase the electrical conductivity. After 315 charge/discharge cycles Sn@carbon anode exhibited high specific capacity of 638 mAh g−1 with the low capacity fade of average 0.11 mAh g−1 per cycle. Sn@carbon based anodes was demonstrated to have promising potential for high performance lithium ion batteries application. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Energy Materials Wiley

Abstract

A three‐dimensional porous core‐shell Sn@carbon anode on nickel foam substrate was fabricated by electrostatic spray deposition (ESD) technique followed by high temperature treatment. The carbon shell with a thickness of about 3.2 nm was formed on porous Sn structure at high temperature. 3D porous structure and carbon shell were designed to buffer volume expansion/shrinkage of Sn lattice upon cycling and increase the electrical conductivity. After 315 charge/discharge cycles Sn@carbon anode exhibited high specific capacity of 638 mAh g−1 with the low capacity fade of average 0.11 mAh g−1 per cycle. Sn@carbon based anodes was demonstrated to have promising potential for high performance lithium ion batteries application.
