Research on key technologies of new lithium-sulfur chemical energy storage batteries

Recently, the “Key Technology Research on New Lithium-Sulfur Chemical Energy Storage Battery” project undertaken by the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences in the advanced energy technology field of the National “863 Program” participated in Beijing organized by the Energy Division of the High Technology Center of the Ministry of Science and Technology Technical acceptance. Chen Jian, head of the High-Tech Research and Development Center of the Ministry of Science and Technology, member of the acceptance expert group, project leader, and members of project participating units attended the meeting. The expert group listened to Chen Jian's work report, reviewed the acceptance materials, and unanimously agreed that the subject passed the technical acceptance.

During the implementation of the project, the lithium-sulfur battery Ru0026D team of Dalian Institute of Physics has overcome a series of battery engineering technical problems, including key battery materials, key components, battery and battery pack technology, etc. A series of results have been achieved in this regard. Lithium-sulfur batteries have excellent characteristics such as high specific energy and will be widely used in civilian and national security fields such as unmanned aerial vehicles, electric vehicles, and smart micro-grid energy storage power stations. The 'high specific energy, large capacity lithium-sulfur secondary batteries and battery packs' developed by Dalian Chemical with independent intellectual property rights are currently reported to have the highest specific energy lithium-sulfur batteries and battery packs in the world.
