Abstract
En 中文
Rechargeable lithium-chlorine (Li-Cl2) batteries have garnered significant interest due to their high energy density, yet challenges such as the cycling stability and low-temperature adaptability remain to be tackled. This study successfully applied high surface area activated carbon material (3200 m2 g−1) to the cathode of a lithium-chlorine battery with AlCl3, LiFSI, LiTFSI, LiCl, and SOCl2 electrolytes, which demonstrate exceptional electrochemical performance. The results indicate that the Li-Cl2@AC battery can be cycled stably within a wide current density range of 0.5−5 A g−1. Remarkably, the system exhibits an anomalous low-temperature enhancement effect: at −20 °C, a high capacity of 2000 mAh g−1 is demonstrated, and a stable charge/discharge for over 410 cycles is achieved, a performance significantly superior to that of room temperature. Mechanistic studies show that the low-temperature environment effectively reduces the generation of irreversible LiCl and enhances Cl2 availability, thereby substantially extending the cycle life of the battery. This work not only demonstrates the potential of high surface area activated carbon materials in Li-Cl2 batteries but also provides an innovative approach to addressing the low-temperature performance issue of high-energy-density lithium-chlorine batteries.
