The sample entropy, fuzzy entropy, localized area and power spectral density values of charging voltage sequences are utilized to develop the hybrid SOH estimation model and thereby minimizing the estimation error values. The health feature variables based on battery charging attributes are validated as per grey correlation analysis to estimate the battery deterioration trends. Different regression models are compared to illustrate the effectiveness and estimation accuracy of the proposed hybrid model. The results demonstrate that the hybrid model trained on localized voltage area-sample entropy feature variables or power spectral density-sample entropy feature variables are more accurate in estimating battery SOH than other estimation models such as Lasso, and support vector regression models.

However, they face critical challenges, including poor oxidative stability at the cathode side and severe [K⁺-solvent] co-intercalation into the graphite anode at the anode side for potassium-ion batteries (PIBs). To address these issues, we present a novel approach using a weakly coordinating solvent—1,2-dimethoxypropane (DMP). Unlike the linear ether molecule 1,2-dimethoxyethane (DME), DMP features an additional methyl group that induces strong steric hindrance. This structural modification reduces the interaction between K⁺ ions and the solvent, forming an anion-rich solvation structure (ARSS) in the low-concentration electrolyte. The ARSS triggers the formation of an inorganic-rich solid electrolyte interphase (SEI) and enables high compatibility with the graphite anode. This results in a high initial Coulombic efficiency (CE) of 80.9% and remarkable capacity retention of 92.4% after 10 months of deep cycling. Furthermore, the ARSS substantially enhances the electrolyte oxidative stability, allowing the K₂Mn[Fe(CN)₆]₂ (KMHCF) cathode to deliver reliable cycling performance over 500 cycles at a high cut-off voltage of 4.3 V.
