Description
Technical Field
The invention belongs to the field of chemical power supply electrode materials, and particularly relates to a Mg-Bi-In-Y anode material of a magnesium air battery, and a preparation method and application thereof.
Background
Magnesium has a more negative standard electrode potential, a larger theoretical specific capacity and a smaller density, and based on the advantages of the above aspects, magnesium is widely applied to various chemical power sources as a more ideal anode material. Meanwhile, the magnesium is rich in the earth crust, the price is low, and in addition, most magnesium alloys are nontoxic and environment-friendly. Therefore, the magnesium alloy has great application potential as a battery anode material, and the research on the electrochemical performance of the magnesium alloy as the battery anode (cathode) material has great significance.
The magnesium-air battery has the advantages of low cost, high energy conversion rate, abundant resources, no pollution and the like, and has great development and application prospects. However, magnesium anodes face the problems of difficult peeling of corrosion products, severe hydrogen evolution self-corrosion reaction, falling of metal particles, low anode utilization rate and the like in the application process, and limit the further development of magnesium-air batteries. Furthermore, magnesium-air batteries require extended storage times when not discharged, which places high demands on the corrosion resistance of the magnesium anode at open circuit potential. Therefore, the search for high-performance magnesium alloy anode materials is one of the hot spots and difficulties in the research of magnesium-air batteries, and the key is to search for novel magnesium-based anode materials with high reactivity, slow corrosion rate and high anode utilization rate to solve the contradiction between activation and passivation.
Currently, the addition of other alloying elements to magnesium is a conventional method for effectively increasing the anode utilization of magnesium alloys. One or more elements of aluminum, zinc, tin, indium, bismuth, lead, gallium, manganese and the like are added into magnesium to form binary, ternary or even multi-element magnesium alloy anode materials, so that the discharge activity of the magnesium alloy anode materials is improved, the corrosion homogenization and the grain refinement are promoted, and the corrosion electrochemical performance of the magnesium anode is improved. Currently, the following systems mainly exist in magnesium alloy anodes: Mg-Al-Zn- (RE), Mg-Al-Pb, Mg-Ca, Mg-Li, Mg-Hg-X, etc.
However, there are few reports on microalloying of more than two elements of high-purity magnesium, and there is no report on using high-purity magnesium as a research object, adopting composite addition of bismuth and indium as activating elements, and adding microalloying of yttrium as a rare earth element to solve the contradiction between passivation and activation. In view of this, the invention is particularly proposed.
