文摘

3D hollow microtubular composites are prepared using kapok fiber as template. Surface morphologies of the composites are dependent on the calcination temperature. The composites with nanoflake morphology exhibits excellent electrochemical performance. Natural kapok fiber is expected to design hollow materials for electrochemical storage.
