Herein, we report the effect of using nanoparticles of LiFePO on the electrochemical properties of all-solid-state batteries (ASSBs) with a solid electrolyte. LiFePO (LFP) cathode materials are promising cathode materials in polymer-based composite solid electrolytes because of their limited electrochemical window range. However, LFP cathodes exhibit poor electric conductivity and sluggish lithium ion diffusion.

In this article, we report the effect of a Li6LaZrAlO (LLZAO) composite Li(NiCoMn)O (NCM811) cathode material on the performance of all-solid-state batteries (ASSBs) with oxide-based organic/inorganic hybrid solid electrolytes. The layered structure of Ni-rich cathode material Li(Ni CoMn)O ( > 0.6) (NCM) exhibiting a high specific capacity is among the suitable cathode materials for next-generation energy storage systems, particularly electric vehicles and portable devices for all-solid-state batteries.

In this study, we evaluated the properties exhibited by a composite solid electrolyte (CSE) prepared tailoring the particle size of an active filler, LiLaZrTaO (LLZTO). The average particle size was reduced to 2.53 μm ball milling and exhibited a specific surface area of 3.
