Fudan research and development of new lithium-ion batteries: Charging 10 seconds to run 400 km

Charging time as long as 10 seconds, mileage up to 400 km, so that electric cars and ordinary gasoline in the performance is not very different times coming. The latest issue of "Nature" magazine published in "Science Report" published a research group of Professor Wu Yuping, Fudan University on the aqueous solution of lithium battery system, the latest research results. The reporter learned from a press conference held yesterday at Fudan University that in just a few days, relevant agencies for the development of new energy vehicles in the United States have issued cooperation requests. Fudan scholars hope that this achievement will be applied domestically as soon as possible to promote the accelerated development of the new energy vehicle industry and to play an active role in controlling air pollution. At present, the new energy electric vehicles that have been put on the market in succession have some preferential policies, such as free licenses and subsidies. However, it is very difficult to open the market. One of the key reasons is the battery is not enough to force. Many people are worried about the mileage of new energy vehicles. "If the car out to open to do not come back how to do?" People become the biggest concern to buy new energy electric vehicles. This time, the new lithium-water battery system developed by Professor Wu's team uses composite membrane to encase lithium metal, and uses aqueous solution as electrolyte, which can greatly reduce the cost of the battery and increase the energy density, so that the battery charging time is shorter and the stored electricity is more , Durable longer. This reporter has learned that the market for electric vehicles currently on sale for the 150-180 km, and equipped with this new type of lithium-electric electric vehicles, it is expected to reach 400 km distance travel. Most noteworthy is that the current charging time for electric vehicles on the market needs 8 hours, and equipped with this new type of lithium-electric electric vehicle charging only takes about 10 seconds. In addition, the new lithium-ion battery manufacturing costs only half of the current market price of EV lithium batteries. As a result, electric vehicles and ordinary cars in the performance difference is no longer obvious. Its environmental advantages will be more market attractive. "Once the industrialization of this new type of lithium-water battery, it will be able to completely solve the current security problems of new energy electric vehicles, high cost, short driving distance and other major constraints restricting the development of the three major industries." Professor Wu said. Professor Wu told reporters that after this achievement was published in the "Science" magazine of the magazine "Nature", just a few days ago, there have been requests for cooperation from relevant agencies for the development of new energy vehicles in the United States. However, Fudan University Owners of property rights also hope to seek cooperation with domestic enterprises to apply the results domestically as soon as possible so as to promote the accelerated development of the new energy vehicle industry and at the same time play an active role in controlling air pollution and reducing PM2.5 emission. According to reports, the new water lithium can also be widely used in mobile phones, laptops, large-scale manufacturing equipment and other fields. Compared with the traditional lithium battery, it has another significant advantage is not easy to heat hot, greatly reducing the security risks.
