Abstract Bacterial cellulose (BC)decomposes easily and the carbon residue rate is low. These factors critically restrict its application in fabricating cellulosic carbon materials. Therefore, in this paper, a simple and facile method to improve the BC carbon yield is proposed based on the stretching orientation of BC. By controlling the degree of BC deformation, the orientation and crystallinity of the BC can be adjusted, thereby sensitively affecting the graphitization degree and carbon yield of carbonized BC. Samples were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), Raman scattering, and low-field nuclear magnetic resonance (LNMR). The results indicated that when the pre-stretched strain was 40%, the crystallinity and graphitization degree of BC improved, and the carbon yield increased significantly in comparison to that of untreated BC. Thus, a low-cost, facile, and environmentally friendly method of increasing the carbon yield of BC was developed in this study.

The cycling performance in lithium half cells of Si alloy electrodes with polyvinylidene fluoride or polyimide binders were evaluated after the electrodes were cured at temperatures below and above the binder carbonization temperature. After carbonization, the cycling performance of electrodes using polyvinylidene fluoride binder improved considerably but still suffered from capacity fade. Electrodes with carbonized polyimide binder had superior performance and showed no capacity fade after 100 cycles. The superior performance of carbonized polyimide electrodes is thought to be related to polyimide’s high carbon yield upon heating, resulting in the formation of a uniform carbon coating on alloy surfaces. These results suggest that new high performance binders for alloy electrodes might be derived by the carbonization of polymers with a high carbon yield that lead to the formation of uniform carbon coatings on alloy particles.
