Abstract

We prepared up to 20 μm-thick LiNi_1/3Co_1/3Mn_1/3O₂ (NMC)-Li⁺ conductive glass-ceramic solid electrolyte (LATP: ^σLi ∼ 10^-3 S cm^-2 at 298 K) composite cathode films on Li₇La₃Zr₂O₁₂ (LLZ) substrates by aerosol deposition (AD) and investigated their electrochemical properties as all-solid-state batteries. The resultant NMC/LATP interface in the composite film had a thin mutual diffusion layer (∼5 nm) and a film had a porosity of ca. 0.15% in volume. The composite films were well adhered to the LLZ substrates even though the films were prepared at room temperature. All-solid-state batteries, consisting of Li/LLZ/NMC-LATP composite film (20 μm), repeated charge-discharge reactions for 90 cycles at 100 °C at a 1/10 C rate (capacity retention: 99.97%/cycle). Rate capability of this battery was improved by modifying both the LATP and electron conductive source amount in the composite film, and a battery with 16 μm-thick composite electrode delivered 60 mAh g^-1 at 1 mA cm^-2.
