In the "Exposure of Scientific and Technological Achievements and Patented Technology Release and Trading", high-tech projects such as nuclear radiation detection systems, multi-function satellite command vehicles, smog and visibility detectors have appeared. Among them, a "super lithium battery" has attracted many people's attention. The field staff introduced that this is "high specific energy lithium-sulfur battery and battery technology", conservatively estimated that it is 2-3 times smaller than ordinary lithium battery, energy density is 2-3 times larger, can be widely used New energy vehicles and mobile phones and other products. The specific energy is the energy that can be released per unit weight or unit volume of the battery, and is an important performance indicator of the battery. This "super lithium battery" is the world's most energy-efficient lithium-sulfur battery and battery pack. The world's highest capacity battery 2013 is still in the research stage 　　 Lithium-sulfur batteries are a type of lithium battery. In 2013, this technology is still in the research stage. Unlike lithium-ion batteries used in mobile phones and laptops, they belong to a large family of lithium batteries, but there are many differences in performance and charging and discharging principles. A lithium-sulfur battery is a lithium battery in which a sulfur element is used as a positive electrode of a battery and lithium metal is used as a negative electrode. Wang Guoxu, a senior engineer at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, said that compared with ordinary lithium batteries, lithium-sulfur batteries are smaller in size, battery capacity can be increased by 2-3 times, and there is room for improvement in the future. The 35Ah battery developed by the researchers has a specific energy of 566Wh/kg (measured at 25°C) and 39Ah has a specific energy of 616Wh/kg (measured at 50°C). This is the most energy-efficient lithium-sulfur battery and battery pack that has been reported in the world. Moreover, sulfur is an environmentally friendly element that has little environmental pollution. Can be used in new energy vehicles The cruising range is expected to exceed 500 kilometers 　　 Wang Guoxu said that this "lithium-sulfur battery" has passed the safety test and may be widely used in civilian fields such as new energy vehicles, mobile phones and tablet computers in the future. At present, the battery is the key to restrict the development of new energy electric vehicles, and this technical bottleneck is being gradually overcome. The reporter's query on the network public reports shows that the battery on the electric car is large and heavy due to the low energy density of the battery. Therefore, the number of batteries installed in each electric vehicle is very limited. For example, a battery pack of Tesla is laid on the floor of a car, about 2 meters long and 1.2 meters wide. In the top-of-the-range model, such a large-capacity power battery can provide only about 300 miles (482 kilometers) of mileage, and then need to be plugged into a charging post for charging. Regarding lithium-sulfur batteries, many domestic researches are concerned. On the official website of the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, the research and development goal of lithium-sulfur batteries is: a 200-kilometer lithium-sulfur battery-powered electric vehicle with a range of more than 500 kilometers. Wang Guoxu said that the battery is currently in the intermediate test phase, which is an experiment before industrial production. This means that the "super lithium battery" is not far from our lives. Visit the exhibition "Catch Hunter" appeared to catch the black flying drone With the development of the general aviation field, low-altitude opening is gradually implemented, and there are more and more drones. In particular, some remote-controlled drones are loved by enthusiasts, often "horizontal" regardless of the region, regardless of the scope, causing a lot of trouble for the local public order. At the Expo, Huaxi Dushi Bao reporter encountered a "hunter" who specializes in catching drones - the drone defense system. "Our defense system is more accurate than the similar products in the United States and the United Kingdom, and has added frequency measurement function, which can more effectively interfere with the communication equipment and GPS of different drones." The field staff told reporters that The system consists of three subsystems: KU-band phased array radar system, which can detect and locate low-altitude flying targets in the range of 0.5 km-40 km; and thermomagnetic infrared imaging subsystem for image forensics. Caught the drone, how to deal with it? The last component, the intelligent UAV jamming system, is used to generate electromagnetic interference signals, causing the communication between the drone and the communication ground station to be disconnected, forcing the drone to land or return. "Our system can monitor low altitudes in key areas such as cities, borders, and waterways and quickly handle abnormal situations." The staff revealed that the system has found an intentional party and is talking about cooperation. Interview Academician of the Chinese Academy of Engineering, President of Tongji University, Zhong Zhihua: The automobile structure will revolutionize in the next 5-10 years On September 22nd, the 4th China Science and Technology Fair held the “Made in China 2025 Summit Forumâ€. The theme of the forum is “Innovative and Intelligent Green Developmentâ€, focusing on industry hotspots in the manufacturing sector and jointly discussing the “Made in China 2025†comprehensive innovation reform. At the forum, Zhong Zhihua, president of Tongji University and academician of the Chinese Academy of Engineering, delivered a speech entitled "Made in China 2025 and Automotive Industry Development". As one of the only three academicians of the Chinese Academy of Engineering in China's automotive research field, Zhong Zhihua said in an interview with the media that Sichuan can seize the historical opportunity brought by “Made in China 2025†under the current integration of industrialization and informatization. Make a difference in new automotive technologies and new industry models. Made in China 2025 Will boost the transformation of the automotive industry 　　 "China is a big manufacturing country, but it is not a manufacturing power. Our manufacturing industry faces great development opportunities and faces great challenges." At the beginning of the speech, Zhong Zhihua clarified the background of "Made in China 2025". "Made in China 2025" is to achieve a historic leap from China's manufacturing power to manufacturing power through deep integration of informationization and industrialization. The transformation and upgrading of the automobile industry, the process of the automobile industry from large to strong is basically synchronized with the manufacturing industry. “I expect revolutionary changes in the structure of our cars in the next five or ten years. This revolutionary change comes from changes in our materials and processes,†said Zhong Zhihua. Sichuan auto industry can exert strength on new technologies 　　 On September 7, 2016, the Shenlong Automobile Chengdu plant was officially put into operation. It took only 23 months for the Shenlong Automobile Chengdu plant to start construction and start production, creating an amazing “Chengdu Speedâ€. At the end of this year, the vehicle production in Chengdu Economic Development Zone is expected to exceed the 1 million mark. How can the Sichuan auto industry develop better? Zhong Zhihua said that in the development of the automobile industry, the Sichuan Provincial Party Committee and the provincial government have already made a good strategic layout, and the Sichuan automobile industry has a good foundation in technological innovation. Zhong Zhihua believes that it is still necessary to seize the new historical opportunity, "to make a difference in new technologies and new industrial models, such as new energy vehicles, intelligent network vehicles. At the same time, new materials, new structures, new processes, New equipment and energy-saving cars have great room for development." Sichuan has signed a strategic cooperation agreement with Tongji University. Zhong Zhihua said that the school will try its best to serve local and industry development. 1.
