Recycling graphite from spent Li-ion batteries (LiBs) is critical due to its role in battery manufacturing and increasing global demand. This study evaluated three recovery processes: (1) a cold process, based on mechanical separation; (2) hot using CaO-assisted annealing; (3) wet employing acid leaching dissolve copper. The processes were optimized for efficiency, characterized via SEM-EDS, XRF, XRD, CHN, Raman spectroscopy, assessed environmental economic performance by life cycle approaches. Chemical analyses revealed that the process produced highest-purity (81% carbon) with minimal impurities, making it suitable advanced applications. yielded 74% carbon lowest interlayer spacing (0.354 nm) annealing. While yielding lower-purity graphite, demonstrated superior (single score impact (SSI) of −432 μPt) cost savings $40/kg energy inputs copper recovery. In contrast, incurred significant costs ($420/kg) degradation (SSI 695 μPt), balancing impacts 317 μPt, $159/kg). ideal high-quality applications, while general uses. strikes best balance, highly versatile option.

In the electronic era, demand for efficient storage systems has rapidly increased, making health and durability of batteries crucial. This research investigates performance distinct Machine Learning (ML) techniques—namely, Logistic Regression (LR), Convolutional Neural Network (CNN), CNN tuning using Particle Swarm Optimization (PSO)—for Battery Health Analysis (BHA). The dataset comprises various parameters related to battery health, with Remaining Useful Time (RUL) as target variable. proposed work is evaluated Root Mean Squared Error (RMSE), Absolute (MAE), R-squared (R2) scores. Initially, basic LR Model employed BHA, followed by capture complex data patterns. Subsequently, Model's optimized PSO algorithm, aiming improved performance. Experimental results demonstrate that significantly outperforms approach in terms accuracy, lower RMSE MAE, higher R2 conventional model outperformed approach, resulting a 20.11, MAE 15.26, score 0.996; whereas, PSO-Optimized-CNN further enhanced metrics 14.97, 8.03 0.998. Henceforth, PSO-optimized exhibits compared standalone Model. findings offer valuable insights into ML approaches BHA suggest methods optimizing management applications, including renewable energy systems, electric vehicles, portable electronics.
