Fudan developed a new type of lithium-ion battery or deal with automotive energy issues

The latest issue of 'Sci.ReportThis latest research on aqueous lithium-ion battery systems can increase the performance of lithium-ion batteries by 80%. An electric car can travel 400 kilometers in just 10 seconds. This battery is cheap, safe and not easy to explode. Wu Yuping's research team demonstrated this lithium-ion battery system to reporters on the 13th. A thin piece of lithium metal is tightly wrapped by a special composite film, placed in an aqueous solution with a neutral pH, and assembled with the traditional positive electrode material spinel lithium manganate in lithium-ion batteries to make a uniform A new type of water-lithium battery with a charging voltage of 4.2V and a discharge voltage of 4.0V. This achievement has greatly broken the theoretical analysis voltage of 1.23V for aqueous solutions. According to reports, organic electrolyte power lithium-ion batteries are currently commonly used. In large-scale energy storage systems, traditional lithium-ion batteries have high costs and high requirements for processing conditions, and due to the physical and chemical properties of organic electrolytes, there are major safety hazards. This is also an important obstacle to the lack of large-scale promotion of new energy products such as electric vehicles. This achievement of Wu Yuping's research group provides the possibility for the development of a new low-cost, easy-to-large-scale processing, safe and environmentally friendly battery system. It is said that the new type of water-lithium battery uses an aqueous solution as the electrolyte, which has enhanced flame retardancy, so that the battery is not easy to get hot and heat during use, and has high safety performance. The composite film made of polymer and inorganic materials can reduce the energy consumption of the battery. Drop below 5%. It is estimated that if this battery is used in a mobile phone, the battery of the same size can at least double the talk time of the mobile phone, and the cost is less than half of the original; the same is true for cars, and the pollution to the environment is also greater than that of existing lithium Ion batteries are much smaller. Wu Yuping said that the U.S. Energy Institute has targeted this research and hopes to reach a cooperation agreement with him. But he also hopes to cooperate with forward-looking companies in China. He said that the new hydro-lithium battery can be used in all aspects in life. He hopes that the breakthrough of hydro-lithium battery can finally make consumers feel safe, accept the cost, and deal with the current global stagnation of the electric vehicle industry.
