　　The research team composed of Cui Yi, a well-known materials scientist at Stanford University in the United States, and Diwen Zhu, the former Secretary of Energy of the United States and Nobel Prize winner in Physics, has recently made a major breakthrough in the practical application of lithium metal electrodes. The research team with doctoral student Liang Zheng as the backbone put forward the concept of "lithophilicity" for the first time, and successfully prepared a composite metal lithium electrode by using the carbonaceous host material treated with the surface "lithophilization". Lithium battery performance.　　According to the Science and Technology Daily News on April 26, in recent years, with the rapid development of portable electronic equipment, electric vehicles and renewable energy, high-energy energy storage devices have become one of the research hotspots in the field of new energy and new materials. Lithium metal has a very high theoretical specific capacity and an ideal negative electrode potential. Secondary batteries with lithium metal as the negative electrode have the advantages of high operating voltage and high energy density, making metal lithium the preferred material in the field of energy storage today. However, various indicators of existing lithium ion secondary batteries, such as capacity, cycle life, charging speed, etc., cannot meet the increasing demands of consumers. Therefore, the development of new electrode materials has become a top priority. The newly researched composite metal lithium electrode has small dimensional changes, extremely high specific capacity and good cycle and rate performance during the cycle of carbonate electrolyte system. Its voltage curve is also relatively smooth, which breaks through the current restrictions on metals. The main problem of large-scale commercialization of lithium batteries.
