This latest research on the aqueous lithium battery system can increase the performance of lithium batteries by 80%. An electric car can travel 400 kilometers in just 10 seconds. This battery is cheap, safe and not easy to explode.

　　"Sci.Report", a sub-issue of "Nature" magazine, published an important research result of a group of professor Wu Yuping of Fudan University. This latest research on aqueous lithium battery systems can increase the performance of lithium 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 battery system to reporters. A thin piece of lithium metal is tightly wrapped by a special composite film, placed in an aqueous solution with a neutral pH value, and assembled with the traditional cathode material spinel lithium manganate in lithium-ion batteries to make an average 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 exceeded the theoretical decomposition voltage of 1.23V for aqueous solutions.

　　According to reports, organic electrolyte power lithium-ion batteries are commonly used. In large-scale energy storage systems, traditional lithium batteries have high costs and high requirements for production conditions, and due to the physical and chemical properties of organic electrolytes, there are greater safety hazards. This is also the main obstacle to the lack of large-scale promotion of new energy products such as electric vehicles.

　　It is estimated that if this battery is used in mobile phones, the same size battery can at least double the phone talk time, and the cost is less than half of the original; the same is true for cars, and the pollution to the environment is also higher than that of existing lithium The battery is much smaller.
