采用原子吸收光谱法研究了橄榄石型LiFePO 4和尖晶石型LiMn 2 O 4在LiPF 6基电解质中的稳定性。与60 ℃储存的阴极材料相比，在85 ℃下观察到Mn/Fe溶解的显著增加。然而，该比较表明LiFePO 4相对于LiMn 2 O 4的溶解度低得多。这一结果显示了LiFePO 4作为有前途的替代阴极的新优势。(C)2003 Elsevier Science B. V.保留所有权利。
The stabilities of olivine LiFePO4 and spinel LiMn2O4 in a LiPF6-based electrolyte were investigated by means of atomic absorption spectroscopy. At 85 degreesC a significant increase in Mn/Fe dissolution was observed in comparison to 60 degreesC stored cathode materials. However, the comparison indicates a much lower solubility of the LiFePO4 versus LiMn2O4. This result shows a new advantage of LiFePO4 as a promising alternative cathode.
