On March 13th, the latest issue of "Nature" magazine "Sci.Report" published a heavy research result of the research team of Wu Yuping, a professor of Fudan University. The latest research on the lithium battery system of the aqueous solution can increase the performance of lithium battery by 80%. Electric vehicles can drive 400 kilometers for only 10 seconds. This battery cost is low, and safety is not easy to explode.

　　Wu Yuping's research group showed reporters this lithium battery system on the 13th. A thin metal lithium is tightly wrapped in a special composite membrane, placed it in a neutral aquatic solution in the pH value, and assembled with the traditional positive pole tinocarblyite in the lithium -ion battery, which can be made into an average. The charging voltage is 4.2V and the discharge voltage with a discharge voltage of 4.0V, which greatly breaks through the theoretical decomposition voltage of the aquatic solution by 1.23V.

　　The results of the Wu Yuping's research group provides possibilities for developing new types of low -cost, large -scale production, and safe and environmental protection battery system. It is said that the new type of water and lithium battery uses water solution as an electrolyte, which is enhanced by flame retardant, so that the battery is not easy to cause perm and heat during use, and the safety performance is high; make a composite film with polymer materials and inorganic materials, which can consume the energy loss of the battery. Drop to less than 5%.

　　It is estimated that if this battery is used for mobile phones, a battery of the same size can be extended at least double the call time for the phone, and the cost is less than half of the original; The battery is much smaller.

　　Wu Yuping said that the American Institute of Energy has "aimed" the study, hoping to reach a cooperation intention with him. But he hopes to cooperate with a forward -looking company in China. He said, "The new type of water and lithium batteries can be applied to all parties in life. It is hoped that the breakthrough of lithium batteries can ultimately enable consumers to rest assured, accept costs, and solve the current electric vehicle industry in the world."
