Researchers have developed a high-throughput, one-minute process for printable thin-film ceramic solid-state electrolytes (SSEs) called "Robust LLTO" (R-LLTO). R-LLTO exhibits excellent mechanical properties, with flexibility, low modulus (~35 GPa), and high fracture toughness (>2.0 MPa m). This opens new design possibilities for robust solid-state batteries with improved energy density and processability compared to traditional SSEs.
How Paios was used
The complex impedance response of the inplane configuration was measured using a Paios measurement system (Fluxim AG) by varying the frequency from 10 Hz to 10 MHz for an applied voltage with an amplitude of 50 mV. Data from EIS measurements were fitted with simulated response of equivalent circuits using Fluxim’s Characterization Suite software.
