Fecha de publicación: | 2018 | Editor: | Springer Nature | Citación: | Surface Engineering and Applied Electrochemistry 54(1): 55-63 (2018) | Resumen: | Mesoporous iron phosphates were synthesized using sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB) as surfactants. The material synthesized in the presence of SDS was not applied as a positive electrode active material of a lithium battery. The results show that the obtained FePO4 has a mesoporous structure with a specific surface area of 70 m2 g−1 and a dominant pore diameter of 3 nm. Those mesoporous were characterized by different microstructural and electrochemical analyzes. Among the materials studied under different conditions, those calcined at 450°C preserve mesoporous structures and exhibit the best electrochemical performance when used as active materials of the positive electrodes of lithium batteries. Effectively, a relatively high specific capacity of 135 and 122 mAh g−1 was registered at C/20 collected experimentally by the samples synthesized in the presence of SDS and CTAB, respectively. | Versión del editor: | https://doi.org/10.3103/S106837551801012X | URI: | http://hdl.handle.net/10261/199904 | DOI: | 10.3103/S106837551801012X | ISSN: | 1068-3755 | E-ISSN: | 1934-8002 |
