dc.description.abstractThis study investigates the concentration effect of chitosan on the formation of iron oxide composites and their electrochemical performance as anode materials in Li&#8211-
dc.description.abstraction batteries. The molecular bridging effect of chitosan chains induces the clustered aggregation of citrate&#8211-
dc.description.abstractcapped Fe3O4 (C&#8211-
dc.description.abstractFe3O4) through the electrostatic interactions between carboxylate groups of C&#8211-
dc.description.abstractFe3O4 and amine groups of chitosan. The thermal calcination of chitosan&#8211-
dc.description.abstractlinked Fe3O4 leads to carbon&#8211-
dc.description.abstractcoated Fe2O3 (Fe2O3@carbon) with the mesopore range of porosity (20&#8211-
dc.description.abstract30 nm). The mesoporous Fe2O3@carbon exhibits an improved electrochemical performance as anode materials in Li&#8211-
dc.description.abstraction batteries. The capacity retention of Fe2O3@carbon is twice that of bare Fe2O3 after the 50th cycle at 0.1 C. During the charge&#8211-
dc.description.abstractdischarge process, the Fe2O3@carbon (3 ml of chitosan) exhibits the highest retention capacity among as&#8211-
dc.description.abstractprepared samples, whereas Fe2O3@carbon (1 ml of chitosan) exhibits the lowest retention capacity owing to the weakly cross&#8211-
dc.description.abstractlinked iron oxides. The improved performance of Fe2O3@carbon as anode materials is mainly attributed to the optimal cross&#8211-
dc.description.abstractlinking effect and structural integrity of mesoporous composite which is beneficial for the effective transport of electrolytes and/or Li&#8211-
dc.description.abstractons, suggesting a useful guideline for preparing porous electrode materials using metal oxide particles.-
