摘要: In order to better resolve the large volume expansion problem of SnO2-based anode materials, a hollow bean-pod-like SiO2-supported-SnO2/C nanostructure with sufficient internal void space is designed. Dual voids exist in this structure combination SiO2 support core and carbon as an outside shell, providing triple guarantees improve performance materials for Li Na storage. As result, after 550 charge/discharge cycles, discharge capacity 649 mA h g−1 can still be obtained storage, 104 maintained 1000 cycles
