Description
Summary:Solution combustion synthesis (SCS) is considered as an efficient and energy-saving method for preparing LiFePO[sub.4]/C composite material with the nanostructure (Nano-LiFePO[sub.4]/C). In this study, Nano-LiFePO[sub.4]/C cathode material was prepared using SCS using a cost-effective combination of urea and sorbitol as mixed fuels. The effect of mixed fuels on combustion behavior and microstructure as well as on electrochemical performance was studied using XRD, BET, SEM, TEM, and electrochemical characterization methods. Multiple characterization results indicated that the maximum temperature (T[sub.m]) and particle size were influenced by the usage of urea and sorbitol. The sample derived under optimum conditions exhibits a mesoporous nanostructure with a large surface specific area and attractive electrochemical performance with a discharge capacity of 153.5 mAh/g at 0.1 C, which shows strong potential for commercial applications in the future.
