In this study, we uncovered the potential of 2D puckered chromium ditelluride (CrTe<sub>2</sub>) as a novel anode material for multivalent metal-ion batteries employing Li ions, Mg ions, and Al ions. The structural and dynamical stability of the material was ensured via formation energy and phonon dispersion curves. The optimal anodic properties of the material were systematically analyzed, with a focus on its structural properties, electronic characteristics, adsorption sites, diffusion barriers, and storage capability. The exothermic interactions of Li, Mg, and Al with host CrTe<sub>2</sub> demonstrated its suitability for the intercalation process in respective monovalent, divalent, and trivalent ion batteries. The storage capacity of the material appeared as 1745 mAh g<sup>–</sup><sup>1</sup> for LIBs, 872 mAh g<sup>-1</sup> for MIBs, and 785 mAh g<sup>–</sup><sup>1</sup> for AIBs. The open-circuit voltage is found as 0.76 V for Li, 0.97 V for Mg, and 0.62 V for Al. The diffusion barriers faced by Li, Mg, and Al atoms are found to be low at 0.26 eV, 0.55 eV, and 0.42 eV, respectively, which points to the rapid charging capability of the battery. Furthermore, the electronic transport properties of the host material are also studied using a combined density functional theory (DFT) and Green's function method (DFT-GF).

The prediction of SOH has witnessed significant advancements recently, largely propelled by the powerful nonlinear modeling capabilities of deep learning. Despite these advancements, the intricate nature of the battery degradation process poses a challenge in accurately simulating it using measurement data. In this paper, we introduce a novel approach by focusing on the charging voltage deviation, which is defined as the discrepancy between the charging voltage and its average value over each charge/discharge cycle. This deviation is rooted in the electrochemical reactions that lead to capacity decay and voltage fluctuations. We propose a convolutional neural network-long short-term memory (CNN-LSTM) hybrid framework aimed at estimating the SOH of the battery. For each charge/discharge cycle, a conventional CNN is employed to extract key capacity features from sequential charging data, encompassing voltage deviation, current, and charging duration. Following this, an LSTM network is leveraged to build the long-term dependencies of battery capacities, facilitating the SOH prediction process. The experimental results indicate that our model not only simplifies the computational complexity but also significantly enhances the precision of SOH predictions.
