2_02i/2012Lithium-Ion Batteries: Three-Dimensional Porous Core-Shell Sn@Carbon Composite Anodes for High-Performance Lithium-Ion Battery Applications (Adv. Energy Mater. 2/2012)

The big challenge of repeated volume expansion/contraction upon cycling inhibits Sn anodes from application in high-performance lithium ion batteries, despite superior lithium storage. 3D porous core-shelled Sn@carbon composite anodes fabricated by electrostatic spray deposition are described by C. Wang and co-authors on page 238. These composites show excellent battery performance over a long cycle life. A high energy capacity of 638 mAh g−1 is achieved in the 315th charge/discharge cycle with a low capacity fade of 0.11 mAh g−1 per cycle. This enhanced performance is mainly attributed to the porous structure and conductive carbon shell, which acts as an interconnected buffer cushion to alleviate volume change during charge/discharge cycling.
