Battery performance has become one of the key factors determining the usage time of electronic products after each charge and the driving range of new energy vehicles. Although great expectations are placed on lithium metal batteries, they have long been plagued by technical bottlenecks such as "lithium dendrite growth", "thermal runaway", and "interface instability".

Recently, the team led by Liu Kai, a professor from the Department of Chemical Engineering at Tsinghua University and the chief scientist of Xinyuan Qingcai Technology (Beijing) Co., LTD. (referred to as "Xinyuan Qingcai"), a company served by ZGC Development Group, published their research result of applying supramolecular chemistry in lithium metal batteries——Supramolecular Chemistry for High-Performance Lithium Metal Batteries—— in the academic journal CCS Chemistry, providing a unified molecular design paradigm and approach to enable lithium metal batteries with high energy density, long life and high safety.

Xinyuan Qingcai was jointly founded by Tsinghua University and China Electricity. It is the sole technological achievements transformation unit of Tsinghua University in the field of supramolecular materials, enjoying a wide reputation in the industry.

Its technical team has gathered top material experts both at home and abroad. Its core technologies cover multiple cutting-edge fields such as new energy materials and high-performance environmental protection materials. Its products are widely used in many key industries such as new energy vehicles, electronics, and green buildings, with broad market prospects.

The technological breakthroughs and industrial advancement of Xinyuan Qingcai cannot be separated from the "incubation soil" provided by ZGC Development Group. Since moving into the ZGC Frontier Technology Research Institute under the ZGC Development Group in 2023, the company has relied on the "front store, back factory" model of the institute to build its headquarters, pilot R&D pipeline and new energy fire-fighting equipment production line in Fangshan District, Beijing. It has also developed rapidly based on the all-round and full-cycle services provided by the research institute, covering technology transfer, spatial support, fintech, intellectual property, resource connection, etc.

A series of leading technological achievements of Professor Liu Kai's team have also accelerated their transformation under the support of such an innovative ecosystem, facilitating the application of lithium metal batteries with better performance, injecting new impetus into the new energy field, and becoming an important force in promoting the upgrading of the green energy and new materials sectors in Fangshan District.
