Embodiment approach

[0028] The present invention can have various implementations, and four implementations thereof are introduced below.

[0029] Option 1: It is a lithium-air battery with powder particles back to oxygen, see figure 1 . The working principle has been introduced in the section of the invention, and the key to its implementation is:

[0030] 1. The diameter of lithium powder is twice that of oxygen ion

[0031] 2. The concentration of oxygen ions in the oxygen ion chamber should be as high as possible.

[0032] 3. The distance between the catalytic layer and lithium powder should be as small as possible.

[0033] Option 2: Lithium brings back the oxygen-lithium-air battery, see figure 2 .Its working principle is to press lithium metal into a ribbon (9), enter the oxygen anion chamber (4) like lithium powder, and let the lithium positive ions on the surface of the lithium belt combine with the oxygen anions to form Li 2 O. Li 2 O must be attached to the lithium band surface...

Abstract

The invention relates to a back-oxygen lithium-air battery technology. According to the technology, the battery chemical reaction for combining lithium ions with oxygen ions is retained, but the position of the reaction is moved outside a catalyst layer, and an electrolyte is not used, so that reactants can be discharged conveniently. By the back-oxygen lithium-air battery technology, a lithium-air battery can work stably.

Description

1. Technical field: [0001] A new type of mechanochemical battery belongs to new energy technology. 2. Technical background: [0002] Researchers have seen the great advantages of lithium-air batteries, but also understand that it has several insurmountable hurdles that have prevented nearly a decade of effort from reaching practical use. [0003] "Fuel Cell Technology" published by the Electronic Industry Press is described in the oxygen reduction reaction section on page 37: for such a complex electrode reaction (including the reaction of the air electrode in the lithium-air battery), it is impossible to be an intermediate state, but can be Write down various reaction mechanisms, but there is no recognized detailed reaction process yet. [0004] Since the lithium in the lithium-air battery must be reduced in contact with oxygen, and because the lithium redox product is a solid, all electrode catalytic products are gas and liquid, and there is no solid, and the solid will d...
