Resumen de: AU2023301657A1
The invention relates to improved formation protocols for NIB hard carbon anodes in superconcentrated ionic liquid electrolytes. In contrast to established methods for carbonate-based solvents, a high current density 2 C formation protocol resulted in the highest specific capacity during subsequent cycling at 1/2 C current density, along with the lowest EIS resistance, compared with 1 C and 1/10 C formation protocols. Variable cycling conditions (e.g., 1/5 C for long term cycling) were not influenced by the high C-rate treatment, demonstrating the necessity of applying high rate formation protocols for conditioning in these electrolytes. XPS and NMR analysis revealed a thinner SEI layer was formed after high C-rate formation, which can facilitate the Na+ charge transfer and diffusion across the electrolyte/electrode boundary.
