LRMs cathode based all-solid-state lithium-ion batteries with an energy density beyond 400 Wh kg-1

12.22.25 | Higher Education Press

Due to their high energy density and safety, all-solid-state lithium-ion batteries (ASSLBs) with lithium-rich manganese-based materials (LRMs) are exploited as next-generation energy storage systems. However, the severe interfacial degradations with halide solid electrolytes (SEs) caused by the irreversible oxygen release remain a big challenge.

Herein, we synthesized Cr-substituted LRMs with high capacity and stability. The reversible redox of Cr 3+ /Cr 6+ contributes to an enhanced capacity, accompanied by the reversible migration of Cr 6+ ions between octahedral and tetrahedral sites, effectively maintaining the structural stability of LRMs. Meanwhile, the strong Cr–O bond can stabilize the lattice oxygen, establish a stable cathode/electrolyte interface, and alleviate the voltage decay.

This work paves a path for rationally designing LRMs cathode to achieve advanced ASSBs with high energy density and long cycling stability. The work titled “ Cr-doped lithium-rich manganese-based materials as a cathode for high-performance all-solid-state lithium batteries ”, was published on Acta Physico-Chimica Sinica (published on Oct. 14, 2025).
