Fudan University Professor Developed a New Type of Lithium Battery

A "natural" magazine sub s "science reporting" (Sci.Report) published a heavy research Fudan University, Professor Wu Yuping Task Force. The latest research on an aqueous solution of lithium battery systems, lithium battery performance by 80%. Electric car charging only need 10 seconds to travel 400 kilometers, this battery cost, security is not easy explosion.

Wu Yuping research group showed reporters on the 13th of this lithium battery system. A thin layer of metallic lithium, a special composite membrane tightly wrapped, to be placed in the pH value was in the neutral aqueous solution, an average, can be made with the traditional cathode materials in lithium ion battery spinel manganate lithium assembly charging voltage of 4.2V, the discharge voltage of 4.0V new water lithium battery, this result greatly exceeded the aqueous solution of the theoretical decomposition voltage 1.23V.
According to reports, the commonly used organic electrolyte lithium-ion battery. The large energy storage system, the traditional high cost of lithium batteries, the high requirements on the production conditions, and because the physical and chemical properties of the organic electrolyte, there is greater safety hazards. This is the new energy products such power car is not the main obstacle to large-scale promotion.

Wu Yuping Task Force of the achievements on the development of a new low-cost, easy to mass production, possible safety environmental protection battery system. Allegedly, the novel water lithium using the aqueous solution as electrolyte, a flame retardant enhanced, so that the battery during use less hot fever, high safety performance; composite film made of a polymer material and an inorganic material, capable of the energy loss of the battery below 5%.

It is estimated that if this battery for mobile phones, the battery supplier of the same size at least be able to extend the phone talk time doubled, the cost is less than half of the original; same used in automotive pollution on the environment than existing lithium The battery is much smaller.

Wu Yuping said U.S. Energy Research Institute "aiming" in the study, and his hope to reach a cooperation intention. He also hoped that a forward-looking enterprise cooperation with the country. He said, "novel aqueous lithium in life can be specifically applied to on all sides, I hope the water lithium breakthrough to end, the consumers of safe, accepted on costs, the solution to the current global faltering electric car industry .
