Fig. 6: Cycling performance of IAF Li metal pouch cells.
a, b The 1st cycle charge-discharge potential-time profiles of 1.8 Ah IAF Li metal pouch cells with NMC622 positive electrode tested at high-pressure conditions, which was charged through CC and MPC protocol, respectively, and then discharged with CC protocol at 0.3 A. c, d Discharge capacity and coulombic efficiency, and Discharge energy density of 1.8 Ah IAF Li metal pouch cell tested under high-pressure conditions with different charge protocols and the same discharge protocol (Supplementary Table 4), the electrolyte here is 1 M LiPF6 in EC/DEC (v/v, 1/1) with 10 wt% FEC. e Discharge capacity and Coulombic efficiency of 1.5 Ah IAF Li metal pouch cell tested under high-pressure conditions, the electrolyte here is 2 M LiDFOB and 1.4 M LiBF4 in FEC/DEC (v/v, 1/2). f Comparison for the cycling performance of current work with existing results.
