【 摘 要 】
tsA binder-free and freestanding all-climate cathode FeS2@C/CNT in aluminum-ion batteries working from −25 to 50 °C with exceptional flexibility, enhanced capacity retention (above 117 mAh g−1) and rate capacity even at a low temperature of −25 °C.High rate capacity (above 151 mAh g−1 at 2 A g−1) and robust long-term stability (above 80 mAh g−1 after 2,000 cycles at 1 A g−1) at room temperature.DFT simulation verifies that the well-designed structure restricts FeS2 pulverization and facilitates the kinetic process of active ion.
