|
In this work, dispersion on banana-peel-derived carbonaceous supporting material addresses pure tin anode's volume variation and poor cycling performance. The Sn/C composite was prepared using reductive deposition of metallic tins directly on the carbon matrix. The composite electrode delivers a specific capacity of 307.7 mAh g–1 at a specific current of 0.1 Ag–1 after 350 cycles. Noticeably, the rate capability of the Sn-anode is significantly improved by decorating it with carbon materials, which is demonstrated by a rate capacity of 319.9 mAh g–1 at a specific current of 10 A g–1. These improvements could be attributed to the buffering effect of the carbon matrix, which could not only well-accommodate and relieve the lattice strains raised by significant volume variations of alloying anode but also stabilize the solid electrolyte interphase and significantly increase the charge conductivity of the composite electrode. |
