Engineering Ni-Rich Cathode-Solid Electrolyte Interfaces for Low-Pressure All-Solid-State Lithium-Ion Batteries

Lithium-Ion Batteries/TBA
The development of high-energy-density lithium-ion batteries (LIBs) is essential for advancing electric vehicles (EVs) and large-scale sustainable energy storage. However, the pursuit of higher energy density also introduces increasingly stringent safety and reliability challenges. Ni-rich layered oxide cathodes, such as LiNixCoyMnzO2 (NCM, x ≥ 80%), are among the most promising candidates for next-generation, high-energy LIBs owing to their high specific capacities (>200 mAh g⁻¹) and high operating voltages. Nevertheless, increasing the Ni content significantly enhances surface reactivity and exacerbates volume changes during lithiation and delithiation, leading to severe interfacial compatibility issues with solid electrolytes.
This presentation highlights our recent efforts to address two critical interfacial challenges that limit the practical implementation of all-solid-state lithium-ion batteries (ASSLIBs): (i) mechanical debonding at the NCM–Li3InCl6 (LIC) interface and (ii) electrochemical degradation at the NCM–PEO interface, under low stack-pressure (~2 MPa) operating conditions. Achieving stable battery operation under low stack pressure is widely regarded as one of the key requirements for the commercialization of ASSLIBs. We will demonstrate effective interface engineering strategies that substantially improve both mechanical integrity and electrochemical stability, enabling stable operation under practical pressure conditions. These findings may provide valuable insights into interfacial design and offer promising routes toward the development of safe, high-energy-density all-solid-state lithium-ion batteries.
