摘要：

The internal structure of carbon aerogels (CAs) is a key factor affecting their electrochemical performance and applications. In this study, the morphology of CAs and their effects on electrochemical properties were investigated via the control of the carbonization temperature. CAs were prepared by freeze-drying combined with high-temperature carbonization using wood cellulose as the raw material. The nanoplate and nanofiber structures of CAs were manipulated via the control of the carbonization temperature. Results revealed that the volume shr...
