Brief Introduction:
Potassium bromide (KBr) has been widely used in various applications due to its unique properties. In the field of supercapacitors, KBr is added to aqueous electrolytes to enhance the specific capacitance and energy storage capabilities of activated carbon electrodes. It acts as a redox additive, significantly improving the ionic conductivity and reducing the equivalent series resistance, thereby increasing the specific power and energy density of the supercapacitor devices. In perovskite solar cells, KBr is employed as an anti-solvent additive to improve the crystallinity of the perovskite layer, passivate surface defects, and suppress nonradiative recombination, leading to higher power conversion efficiencies and enhanced stability. In perovskite light-emitting diodes, KBr is used for surface passivation, enhancing the photoluminescence quantum yields and stability of blue-emitting perovskite nanostructures.
Halides
KBr is a halide compound, specifically a bromide, because it contains bromine (Br) as the anion.
Inorganic Compounds
Potassium bromide (KBr) is an inorganic compound composed of potassium (K) and bromine (Br).
Ionic Compounds
KBr is an ionic compound, consisting of potassium ions (K⁺) and bromide ions (Br⁻).
Electrolytes
In aqueous solutions, KBr dissociates into ions and can conduct electricity, making it an electrolyte.
