Application of molybdenum foil in aluminum ion battery
Molybdenum foil is a thin sheet made of transition metal molybdenum material, which has the characteristics of high purity, low resistance, good electrochemical performance and chemical stability, so it can be used as a fluid collector in aluminum ion batteries, and can be used as a fluid collector in the battery to a certain extent.
Aluminum ion battery is a rechargeable battery composed of a negatively charged aluminum anode, a positively charged graphite cathode, a diaphragm and an electrolyte, which has similar functions to lithium-ion batteries. Due to the advantages of abundant and easy access to aluminum resources, the use of non-flammable and electrochemically stable electrolyte, and the high theoretical specific capacity of aluminum metal anode, it has been highly concerned by the majority of energy storage researchers.
However, the development of aluminum-ion batteries also faces many problems, such as fluid collection problems, aluminum anode corrosion problems and high electrolyte costs. Among them, the current good use of fluid collectors are mostly inert and stable metal molybdenum foil and tantalum foil in the corresponding voltage range of the electrolytic liquid system, but such metals are rare metals and relatively expensive. Note: Fluid collection refers to the structure or part that collects the current, and can output the large current collected.
Compared with inexpensive metal nickel foil and titanium foil, molybdenum foil has better electrochemical performance and chemical stability in the application of aluminum ion batteries, so it can better ensure the stable operation of the battery. The study shows that nickel foil in aluminum ion battery system will have chemical corrosion, and adverse side reactions will occur at low potential, and the voltage tolerance range is narrow.
Mosten Alloy can produce molybdenum sheet, molybdenum block, molybdenum foil, molybdenum rod, molybdenum wire, molybdenum processing workpiece according to customer demand.
