What are the disadvantages of lithium-air batteries?

The disadvantage of lithium-air battery is what lithium void is a battery system that uses lithium as the negative electrode and oxygen in the air as the positive electrode. Of course, the oxygen electrode requires porous carbon as the reaction carrier. Although great progress has been made in catalyst selection, mechanism discussion, electrolyte selection, and charging over the years, the empty lithium battery as a product has four fatal flaws: the first is the control of water. An empty lithium battery is an open system, unlike a lithium battery, it uses oxygen in the air, and the air contains water, and lithium reacts with water. Oxygen penetration and water resistance are difficult problems to deal with. The second is the catalytic recovery of oxygen. The oxygen reaction is very slow. In order to promote the oxygen reaction, you have to use a very effective catalyst. Nowadays, the catalysts are all precious metals, so you must deploy a very effective and cheap catalyst. This has always been restricting the development of fuel power cells. . Third, the charging of the lithium metal anode. That is, the problem of lithium dendrites has been discussed in the industry. For more than 60 years, countless scientific researchers have come one after another, but there is still no progress. The fourth is the re-differentiation of electric discharge products. The discharge product of lithium-air batteries is lithium oxide, and solid lithium oxide is difficult to reduce to oxygen and lithium.
