Ultra-high-Energy-Density Li Metal Full Cells

(A) Cycling performance of Li (4 mAh cm−2)||NCM811 (4.8 mAh cm−2) cells over a voltage range of 3.0–4.6 V (inset shows the charge/discharge profiles).

(B) Comparison of gravimetric/volumetric energy densities between this study and previously reported LMBs and control samples. Detailed information on the cell weight/volume of each system is provided in Table S1.

(C–E) Safety analysis of Li metal full cells in various abuse conditions: (C) Combustion test of 10 mAh pouch-type cells charged to 4.2 V: 4 M LiFSI-PC FEC (upper) and 4 M LiTFSI-DOL/DME (bottom, inset shows the result of 1 M LiTFSI-DOL/DME). (D) Capacity retention of 10 mAh pouch-type cells charged to 4.2 V after the high-temperature storage test (60°C/24 h). (E) Hot-box test (130°C) of 500 mAh pouch-type cells charged to 4.2 V (inset shows the photographs of the cells after the hot-box test).
