The development of electric vehicle technology puts forward higher requirements for high-power output and safety performance of power lithium batteries. Diaphragm electrolyte system is one of the bottleneck problems restricting the rapid development of power lithium batteries, and the development of high-safety diaphragms and new polymer electrolyte systems is essential for improving the overall performance of power lithium-ion batteries. To this end, Cui Guanglei, Executive Director of the Qingdao Energy Storage Institute, led researchers to successfully develop high-safety and high-voltage-resistant power lithium battery separators using technologies such as wet-process papermaking, interface coupling, and functional modification with completely independent intellectual property rights. . At the same time, the researchers successfully developed a rigid, flexible and all-solid polymer electrolyte by using self-developed flame-retardant cellulose as a substrate, through functional modification and coupling and other related processes. Compared with traditional polyethylene oxide pure solid polymer electrolyte, it has higher mechanical strength (45MPa), more excellent rate charge and discharge performance (10C) and wider temperature use range (25°C-160°C) This will enable the new generation of lithium batteries has a broad application prospects and industrial value. At present, Qingdao Energy Storage Institute is optimizing process parameters and is striving to take the lead in realizing industrial demonstration on economical electric vehicles.
At present, more than 80% of Titanium Wires are used as welded wires, such as welding of various titanium equipment, welded tubes, aero jet engine turbine disc and blade of aviation jet engine, etc.
Due to its excellent corrosion resistance, titanium wire has been widely used in chemical, pharmaceutical, paper and other industries, and can be prepared into a mesh for sea water filter, pure water filter, chemical drug filter, etc.

Recently, a new generation of all-solid-state polymer lithium battery was successfully developed based on the Qingdao Institute of Energy Storage Industry Technology, which was established by the Qingdao Institute of Bioenergy and Process Research of the Chinese Academy of Sciences. The battery greatly improves the rate performance and safe use performance of lithium batteries, and will be used first in economical electric vehicles.
