Owing to the limited one-electron transfer, the capacity of I 2 is much lower than the ICl 3 -based batteries. At a high-power density of 4,225 W kg −1, the energy density of ICl 3 can reach 754 Wh kg −1.
The pouch PC-3 had been designed for a capacity of ∼2 Ah. The initial experiment was initiated with PC-1, PC-2, and PC-3 cells. In the later stage of the investigation, PC-4 and PC-5 were fabricated for a more detailed conditioning study. The weight of the pouch cell is an essential factor in determining the cell's actual energy density.
Besides, breaking and reconstructing unstable interphase lead to side reactions and low CEs. The ICl 3 marks the highest attainable working voltage among cathode materials for lithium-ion batteries (Figure 5 E). The maximum working voltage of the ICl 3 battery is about 3.85 V, much higher than the I 2 (3.0 V) and Br 2 (3.3 V) based batteries.
