Abstract
By combining a SnO2 thin film with silicon dioxide microchannel plate (SiO2-MCP), a three-dimensional (3D) structure with enough space to accommodate the volume change of SnO2 during charging-discharging is produced by MEMS and electroless deposition. Owing to the special structure of the MCP, the battery is able to deliver a reversible Li storage capacity of 408 mAhg-1 after 100 cycles. If the current density is reduced to 200 mAg-1 at a constant current during charging and discharging, the battery exhibits reversible capacities of 1575 and 996 mAhg-1 in the first discharging and charging cycle, respectively. However, a reversible Li-storage capacity of only 298 mAhg−1 is obtained after 50 cycles of deep charging at a current of 200 mAg−1. It is found that silicon is involved in the charging-discharging process at a low current.
