Abstract
En 中文
• Voltage-prioritized hierarchical evaluation: First framework establishing voltage stability as prerequisite while maximizing capacity retention under this constraint. • Unified quantitative metrics: Percentage retentions enable direct comparison and hierarchical optimization of capacity and voltage degradation. • Optimal 2.4 V cutoff: Achieves 90.8% voltage retention and 89.3% capacity retention after 300 cycles, balancing redox activation with structural stability.
