Abstract:
Exploration of novel electrochemical storage/conversion devices has been driven by the demand of electric transportation and grid storage, leading to materials and system design innovations.Currently, intensive research has mainly focused on improving the performance of high-energy-density lithium-ion batteries (LIBs) and high-power-density supercapacitors (SCs). Herein, a novel energy storage system is proposed, for which an N-doped carbon interlayer, made up of N-doped graphene or highly nitrogen carbon (HNC), is inserted between the iodine cathode and separator of Li-I2 battery, and the schematic representation are given in Figure below. As present, iodine ions can be generated first through a conversion reaction happening in the cathode, and then dissolve into the electrolytes and be restricted in the interlayer regions to proceed reversible and fast surface reaction between I3-, I- and I2, thus producing a high energy and power battery density.
