摘要： An energy storage device includes a cathode including an active material with a material structure of MXenes, wherein the active material includes at least one electrochemically active component; and a gelatin-based electrolyte containing an aqueous electrolytic solution disposed adjacent to the electrode. The aqueous electrolytic solution is arranged to facilitate a physical and/or a chemical transformation of at least a portion of the active material upon an operation cycle of charging and discharging of the energy storage device.

摘要： The present invention relates to a range of halide organic salts and their use in a cathode of an electrical cell and in batteries. Elemental halides have attracted intense interest as promising electrodes for energy storage. However, they suffer from a number of inherent physicochemical drawbacks, including the volatility of iodine, the corrosiveness of liquid bromine. The salts of the present invention may serve as a cathode matched with a zinc anode avoiding these issues.

摘要： A novel conversion-type rechargeable battery is constructed, the battery using selenium as the cathode material. Preferably, the selenium is coated over the surface of the pores in a mesoporous ion collector such as carbon. A salt of zinc having an organic ion with polar function group is used with the battery, allowing the solvent of the battery to be either organic or aqueous.

摘要： The present invention provides a high output voltage supercapacitor having a cathode including layers of phosphorene, an anode comprising zinc, and an organic-solvent-based electrolyte including zinc. The supercapacitor demonstrates a high anti-self-discharge. The organic electrolyte may include an anhydrous zinc salt, tetraethylammonium tetrafluoroborate, and propylene carbonate (Et4NBF4/PC). The electrochemical stability window of Et4NBF4/PC extends beyond 2.5 V. The supercapacitor can be charged to 2.5 V and possesses high initial discharge voltage. The supercapacitor delivered 130 F g−1 even after more than 9500 cycles at a current density of 0.5 A g−1. More importantly, the supercapacitor exhibits a capacitance retention of 70.16% even after 500 hours self-discharge behavior.
