The invention discloses a lithium air battery. The lithium air battery includes an air chamber and a battery accommodating shell. The air chamber includes a first air inlet / outlet, a second air inlet / outlet and a battery accommodating space. The first air inlet / outlet and the second air inlet / outlet are coaxially arranged; the battery accommodating space is arranged between the first air inlet / outlet and the second air inlet / outlet; a plurality of lithium air cells and at least more than one lithium air battery module are arranged in the battery accommodating shell; multiple lithium air cellsare suitable for being distributed in the battery containing shell at intervals, the layout direction of multiple lithium air cells is perpendicular to the axial direction of the first air inlet / outlet and the axial direction of the second air inlet / outlet, and the lithium air battery module can be formed by multiple lithium air cells. According to the lithium air battery, external gas can be supplied more smoothly, the oxidation / reduction reaction of oxygen of the lithium air battery is improved, the discharge capacity is improved and relatively stable electrical properties can be exerted.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a lithium-air battery. Background technique [0002] The demand for storable large-capacity power generation in digital, motor, and automobile industries is increasing. As the lithium-air battery with the highest capacity in the storage system, it has attracted much attention. According to lithium-air battery positive and negative electrode lithium oxide reaction (2Li+O 2 ->Li 2 o 2 ), its energy density can reach 3500wh / kg, which is more than 10 times higher than that of lithium-ion batteries. The principle of lithium-air batteries is to use oxygen in the air as the positive electrode, so it has advantages in terms of material price and light weight. Sexual medium, lithium-air battery anode metal Li reaction formula is 1 to 4 items.
