Enhanced Multi-level Electrochemical Stabilization (MES-X): Abstract This study introduces a groundbreaking battery stabilization framework called Multi-level Electrochemical Stabilization (MES-X). Our technology overcomes the traditional limitations in energy density, power output, and longevity through three key innovations: Nano-engineered composite anodes featuring doped MXene (3 nm thickness) Selective ion-transport barrier membranes Phase-change thermal regulation using optimized hydrated salts Experimental validation confirms transformative performance: Unprecedented energy density of 365 Wh/kg (35% higher than industry standards) Exceptional power output of 8...
