Interface Modification of NASICON-structured Li1.5Al0.5Ge1.5(PO4)3 (LAGP) by Femtosecond Laser Structuring and Ionic Liquid
NASICON-structured solid-state electrolyte, namely Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP) possesses high ionic conductivity and good compatibility with lithium metal that make it an ideal electrolyte for next-generation lithium battery. However, high interfacial impedance and possible dendrite limit its practical applications. To reduce interfacial impedance, herein, surface texturing on the LAGP is conducted using a femtosecond laser, and further wetted by ionic liquids. The femtosecond laser-modified surface can effectively increase wettability and improve the interfacial contacts. Low area specific impedance of 81.4Ω cm -2 is obtained and the full battery demonstrates good electrochemical performances.
