Emerging exploration and potential development of magnesium hydroxide in energy storage and conversion
Optimizing battery electrode materials
Magnesium hydroxide has gradually attracted attention in the field of battery electrode materials. In alkaline batteries, as an additive, it can improve electrode performance, increase conductivity and stability, inhibit expansion and deformation, and extend battery life. In new magnesium-ion batteries, it is a potential positive electrode material with research value, high theoretical specific capacity, abundant magnesium resources and low cost. Researchers have improved its electrochemical performance in magnesium-ion batteries by regulating crystal structure, electronic structure and exploring suitable electrolyte systems.
Developing supercapacitor electrode materials
Supercapacitors have the advantages of high power density and fast charging and discharging. Magnesium hydroxide is used to prepare supercapacitor electrode materials due to its unique structure and electrochemical properties. After being compounded with carbon materials and metal oxides, the composite electrode material has high specific capacitance and good cycle stability. For example, magnesium hydroxide is compounded with graphene, and the high conductivity and large specific surface area of graphene increase the electron transfer rate. The pseudocapacitive characteristics of magnesium hydroxide provide additional capacitance contribution, showing excellent electrochemical properties, and providing new ideas for the development of supercapacitors.
Potential applications in energy conversion
In the field of energy conversion such as solar cells and fuel cells, magnesium hydroxide has potential application value. In solar cells, it can be used as a buffer layer or interface modification material to improve photoelectric conversion efficiency and stability. In fuel cells, it can be used to prepare catalyst carriers to improve catalyst activity and stability. Researchers have improved the performance of energy conversion devices by regulating surface properties and microstructures to better coordinate with other materials. Although its application in the field of energy conversion is currently in the exploratory stage, it is expected to bring new breakthroughs as research deepens.
