All solid-state lithium batteries come out: solve the bottleneck problem

All-solid-state lithium battery: Double the energy density, solve the bottleneck. The reporter recently learned from the Qingdao Biodynamics and Process Research of the Chinese Academy of Sciences at a related conference, according to a newly developed high-energy density, high-performance all-solid-state lithium battery, which has just passed 11,000 meters. The deep sea imitates the pressure of the warehouse cycle test and is expected to become a potential energy source for all ocean aspirations such as the Jiaolong in the future. It is known that traditional liquid lithium batteries are prone to leaking liquid and explosive safety hazards, but the general performance of solid lithium batteries cannot be considered. Under the guidance of academician Chen Liqun and researcher Cui Guanglei, the Ru0026D team of Qingdao Energy Storage Industry Technology Research Institute of Qingneng Construction has developed a series of all-solid polymer electrolytes with excellent comprehensive performance to solve the above-mentioned bottleneck problems. The results show that the electrochemical window of the new all-solid electrolyte membrane can reach up to 4.6v, and the thermal stability temperature of the electrolyte can reach at least 200℃. When the electrolyte is used in an all-solid-state lithium battery, its capacity remains 92% after 1000 long cycles of charge and discharge. The solid-state battery can be charged and discharged normally, even if the researchers tested it for angle cutting and nail piercing. All these solid polymer electrolytes have high thermal dimensional stability, excellent mechanical strength, wide electrochemical window and high ionic conductivity at room temperature so that the lithium battery electrolyte will seamlessly combine various tracking electrode data. It is expected to be widely used in the processing of lithium batteries for electric vehicles. According to the analysis by the researchers of the Institute of Green Energy, this kind of solid-state battery will not cause safety accidents such as collision, fire, explosion, etc., even under the conditions of car crash, kneading and high temperature extremes. As this study doubles the energy density of lithium batteries, the range of electric vehicles is expected to exceed 450 kilometers, and the range of applications is extremely wide. Its excellent pressure resistance will also greatly promote the development of electric vehicles, spacecraft and deep submersibles.
