Fig. 8 — a Long cycle performance of µSi||NCA (4 mAh cm⁻², N/P = 1.1) in coin cell configuration with comparison for the three investigated electrolytes. b Typical charge/discharge profiles of the µSi||NCA coin cell in FST electrolytes, the inset shows the assembled coin cell with CR2032 cell case. c Practical 100 mAh pouch cell (electrode size of 5 cm by 5 cm) performance with μSi anode at room temperature. d The charge/discharge profiles of the 100 mAh pouch cells at the 1^st, 5^th, 50^th, 100^th, and 120^th cycle. The left inset figure illustrates the test conditions of the assembled pouch cell under the normal pressure of 0.1 MPa, and the right inset shows the actual cell size of 5 cm by 5 cm. For all cells, the cycle rate is C/5 at room temperature with the first formation cycle at C/20. Source data are provided as a Source Data file.
