Abstract Aluminum (Al) exhibits excellent electrical conductivity, mechanical ductility, and good chemical compatibility with high-ionic-conductivity electrolytes. This makes it more suitable as an anode material for all-solid-state lithium batteries (ASSLBs) compared to the overly reactive metallic mechanically weak silicon anode. study finds that pre-lithiated Al demonstrates outstanding interfacial stability Li 6 PS 5 Cl (LPSCl) electrolyte, maintaining stable cycling over 1200 h under conditions of deep charge–discharge. paper combines a high-nickel cathode, LiNi 0.8 Co 0.1 Mn O 2 , paired highly ionic conductive LPSCl design ASSLB high energy density stability. Using pre-lithiation techniques, along dual-reinforcement technology between electrolyte cathode active material, achieves 1000 cycles at 0.2C rate, capacity retention rate up 82.2%. At critical negative-to-positive ratio 1.1, battery’s specific reaches 375 Wh kg −1 maintains 85.9% its after 100 charge–discharge cycles. work provides new approach solution developing low-cost, high-stability batteries.
