    • Abstract


      We report the influence of sodium (Na)-incorporated lithium manganese phosphate as an active material on its performance in electrochemical study for energy storage application. Li$_{1−x}$Na$_x$MnPO$_4$ with different mole ratios ($0.00 \le x \le 0.05$) of sodium is synthesized via a simple sol–gel method. The discharge capacity of Li$_{1−x}$Na$_x$MnPO$_4$ varies with respect to mole ratios of sodium incorporated. The maximum discharge capacityof 92.45 mAh g$^{−1}$ is observed in Li$_{0.97}$Na$_{0.03}$MnPO$_4$, which is higher than that of pristine LiMnPO$_4$ and other Na-incorporated LiMnPO$_4$. The maximum cyclic stability is found to be 84.15% up to 60 cycles. These results demonstrate that Li$_{0.97}$Na$_{0.03}$MnPO$_4$ plays a significant role in future energy storage application.
