Double-layer Si/TiO2NTAs as High Performance Anode for Li-ion Batteries
Year: 2017
Type: article
Abstract: In this paper, a novel three-dimensional TiO 2 nanotube arrays (TiO 2 NTAs) structure was introduced into a silicon electrode. The TiO 2 NTAs acted as both electrochemically active materials and buffers to maintain structural integrity. An initial capacity of 5320 mAh/g was realized, and a The capacity of 1500 mAh/g was maintained after 120 charge/discharge cycles. This good capacity retention benefits from the establishment and maintenance of the excellent structural integrity granted by the introduction of the special TiO 2 NTAs.The superior ability of the TiO 2 NTAs for stress buffering and space accommodation allows the silicon electrode to maintain lower charge transfer resistance during long cycling.
