Lithium-air battery is a very potential high specific capacity battery technology, which uses the reversible reaction of lithium metal and oxygen, the upper limit of theoretical energy density reaches 11000Wh/kg, far exceeding the actual energy density of 200+Wh/kg of lithium batteries, so it has been warmly welcomed by academia and industry, and is widely regarded as a future subversive technology
in the field of batteries.
However, the research on lithium-air batteries has also been a lot of doubts in the industry, and many people believe that lithium-air batteries are not well defined (should be called lithium oxygen), complex reaction mechanism, low polarization, low efficiency, and poor cycle life, which is not a reliable development direction
of the battery industry in the future (power battery demand is an important industry driving force).
Of course, in this process, the researchers have continued to work hard, resulting in many results, and the discussion of the prospects of this direction has also deepened
.
Recently, American scientists have made breakthroughs in the research of lithium-air batteries, and published an article in "NATURE" to successfully make a battery that can circulate more than 700 times in an air-like atmosphere, which solves the problem that many systems can only react with pure oxygen and have a poor cycle life (often only dozens of times), and has made significant progress
in scientific research in this field.
Lithium-air battery technology has always been a hot technology that has attracted people's attention, and its high theoretical energy density has been unanimously expected, but there have been many
problems and challenges in this technology.
The latest research shows that there is great promise to solve an important technical bottleneck, but if the desired goal of industrial practical application is to be achieved, it still has a long way to go, and the joint efforts
of the scientific research community and industry are needed.
