## Description

- description: Cosintered all-solid-state batteries using Li₇La₃Zr₂O₁₂ (LLZ) attract
    attention for their high energy density and long cycle life, but forming low-resistance
    interfaces through cosintering remains challenging due to reaction phases from
    interdiffusion at high temperatures. This study identifies the lithium concentration
    (CLi, mol/cm³) as a key index for predicting the reactivity between LLZ and various
    anode materials during cosintering at 850 °C. Mixing LLZ with anode materials
    of different CLi values reveals that interfacial reactions are significant with
    low CLi materials because of lithium loss in LLZ. In contrast, high CLi materials
    such as Li₂SnO₃, Li₂TiO₃, and Li₃SbO₄ suppress reactions with LLZ, though interdiffusion
    still occurs at the interface, as shown by TEM and lattice parameter analysis.
    Densified composite pellets using LLZTBO−Li₂SnO₃ and LLZTBO−Li₂TiO₃ were successfully
    sintered, and half-cell tests demonstrated high capacity and coulombic efficiency
    for cosintered LLZTBO−Li₂SnO₃ anodes. This approach offers a rapid method to screen
    cosintered electrodes for garnet-type solid electrolytes, advancing high energy
    density battery development.
