Nano-coating on Particles to Improve the Sinterability of Li Ion Conductor

Abstract

In this study, we investigated the enhancement of sinterability and suppression of sintering aid segregation in the lithium-ion conductor LiTa₂PO₈ (LTPO) through a nano-coating approach with MgO. Our findings reveal that the nano-coating technique significantly improves sinterability, requiring less additive compared to conventional methods. The sintered ceramic exhibited a total lithium-ion conductivity of 8.5×10⁻⁵ S cm⁻¹, highlighting the efficacy of the nano-coating method in enhancing sinterability while mitigating segregation issues.
