• Anode pre-lithiation technique promotes the reversibility of aluminum anodes, enabling stable cycling for over 1200 hours in all-solid-state lithium batteries.
• Dual-reinforcement technology addresses interfacial incompatibility between Ni-rich cathodes and sulfide solid-state electrolytes, enhancing cycle stability.
• The fabricated all-solid-state battery achieves 1000 cycles with 82.2% capacity retention at 0.2C, and a specific energy of 375 Wh kg−1 at a negative-to-positive ratio of 1.1.
• This work offers a low-cost, high-stability solution for next-generation all-solid-state batteries, leveraging abundant aluminum and high-nickel cathodes.
