4.4. Experimental ResultsWe compared the proposed LSTM-SCN model with other baseline models, and Table 5 presents the performance metrics of each model on the forecasting set. The LSTM-SCN model demonstrated the best performance across all metrics, with an RMSE of 56.970, an MAE of 43.033, and a MAPE of 0.492%. The RMSE and MAPE values of the LSTM-SCN model are reduced by 6.016 and 0.053%, respectively, compared to the second-best performing CNN-LSTM model.

Abstract Na3V2(PO4)3 is regarded as a promising candidate for sodium ion batteries. Nevertheless, the poor electronic conductivity, low capacities, and unstable structure limit its further investigations. Herein, a new type of Fe/Mn/Co co-substituted Na3V2(PO4)3 with nitrogen-doped carbon coating (NFMC) by a facile sol-gel route is synthesized. The introduced elements feature in both crystal bulk and carbon coating layer.
