Ultra-stable binder-free rechargeable Li/I2 batteries enabled by “Betadine” chemical interaction†
Abstract
An activated carbon cloth/polymer–iodine (ACC/PVP–I2) composite was prepared by the “Betadine” method and employed as a high-performance cathode for rechargeable Li/I2 batteries. Due to the synergistic effect of ACC and PVP–I2, Li/I2 cells with ACC/PVP–I2 as the cathode exhibited superior electrochemical performance.
