Sensitivity analysis, as shown in Figures 7e-g and 6e-g evaluates the input parameter influence on future predictions for M (B) N a and M (P ) N a . Both models demonstrate increased sensitivity to the most recent input data, i.e. cycles 7 to 9 in this provided example, aligned with their attention distributions, with cycle 9 receiving the highest attention. This increased emphasis on the last input cycles corresponds to the rapid degradation patterns in this sodium coin cell. As the model receives each successive cycle, the most recent data, here cycle 9, becomes important in shaping its predictions, allowing the model to more accurately predict ongoing trends.
