[lithium engineering comprehensive report]
Recently, solid state lithium batteries developed by Qingdao Institute of bioenergy and research with the Chinese Academy of Sciences submersible deep sea, full of deep sea to Mariana Trench for demonstration and application. It is reported that this is all solid state lithium China‘s first self-developed submersible can be applied to high energy density, high performance battery, is still able to safely discharge even under 10000 meters deep.
For a long time, people use lithium batteries are basically liquid lithium battery. Liquid lithium battery has mature technology, high production efficiency, the conduction effect is good, but there is also leakage fire risk of explosion of solid state lithium batteries and researchers have been more diligently strive after comprehensive performance. Relying on green can the construction of the Qingdao Energy Research Institute of industrial technology research and development team who won the Cui Guanglei Chen Liquan academy and the National Science Fund for Distinguished Young under the leadership of the development of solid state battery solid interface impedance bottleneck problem, creatively put forward the design concept of "hard and soft" polymer electrolyte, innovative construction the composite electrolyte material system, preparation of solid polymer electrolyte system and a series of excellent comprehensive performance, the development of all solid state lithium battery new high energy density.
It is understood that the all solid state lithium battery energy density has reached 300 kwh / kg, commercial value is 2 times the current liquid lithium battery. Through the five nail experiment, solid-state batteries did not fire and explosion, excellent safety performance, and voltage in pulling out the nails after recovery, once again highlights the self repairing performance and safety performance good solid electrolyte. Related technology has applied for 29 patents in China, the international PCT patents of 3.
"Because of the deep-sea submersible sea with enormous pressure, high energy density, high safety of all solid state lithium battery is the most ideal energy." According to the green energy lithium battery R & D team of scientific research personnel, solid state lithium batteries at the beginning of December 2016 they have passed the Chinese Academy of Sciences Research deep 11000 meters simulated pressure cabin 120 MPa pressure testing online. The ship went to Mariana Trench, is the first full demonstration of the application of deep sea.
