【摘要】：正锂氧电池又被称为锂空气电池,由于其理论能量密度是普通锂离子电池的5-10倍,因而受到了人们的广泛关注~1。目前研究发现大多数基于无水电解液的锂空气电池的相关报道都是采用干燥的纯氧做为正极活性物质,这严重阻碍了锂空气电池的真正实用化发展~2。而要实现锂空气电池的高能量密度,其所需要的氧气应该来自于空气中,就像商业化的锌空气电池一样。然而空气中的水
[Abstract]:Due to its theoretical energy density of 5-10 times that of ordinary lithium-ion batteries, lithium-oxygen batteries are widely concerned by people because of their theoretical energy density is 5-10 times that of ordinary lithium-ion batteries. At present, it has been found that most of the reports of lithium air batteries based on anhydrous electrolytes are using dry pure oxygen as positive active substances, which seriously hinders the development of real application of lithium air batteries. To achieve the high energy density of lithium air batteries, the oxygen needed should come from the air, just like commercial zinc air batteries. But the water in the ai
