| Abstract: | A PAA sol-gel method, which is based on the chelate effect of PAA polymer, was developed forthe synthesis of the spinel LiMn2O4 material. The pyrolysis process of the PAA-nitrate mixture precursorwas investigated by TG and DTA analysis. It is found that the structure and electrochemical properties ofthe material are sensitive to the atmosphere employed in the synthesis process. Preliminary results showthat the material thus prepared has a good electrochemical performance even at high charge and dischargecurrent. |
