Lithium -air batteries are a very potential high -ratio battery technology. It uses a reversible reaction of lithium metal and oxygen. The upper limit of the theoretical energy density reaches 11000Wh / KG, which is far more than the actual energy density of the current 200 + WH / kg of the lithium battery. Therefore The enthusiasm of the academic and industry circles is widely considered to be a future subversion technology in the battery field.
However, the research of lithium -air batteries has always had a lot of doubts in the industry. Many people think that the definition of lithium and empty batteries is unknown (should be called lithium oxygen), the response mechanism is complicated, the high efficiency of polarization is low, and the cycle life is not good. It is not the reliable development direction of the battery industry in the future (the demand for power batteries). Of course, in the process, researchers continued to work hard, producing many results, and discussions on the prospects of this direction are also continuously deepened.(Lithium - Ion Battery Equipment)
Recently, American scientists and others have reached a breakthrough in the research of lithium -air batteries. They posted on "Nature" and successfully made a battery that can circulate over 700 times in the air -like atmosphere. The problem of pure oxygen reactions and poor cycle life (often only dozens of times), and major progress has been made in the scientific research level in this field.
Lithium -air battery technology has always been a hot technology that people valued. The high theoretical energy density has been unanimously expected, but the problems and challenges of this technology have always been very many. The latest research shows that it is very promising to solve an important technical bottleneck. However, if industrial practicality is expected to go to the goal, it still has a long way to go. It also needs the joint efforts of the scientific and industrial circles.
