At the Max Planck Institute for Polymer Research in Germany,

Chief Scientist Cui Guanglei and CEO Dou Xihave embarked on a collaboration to research lithium-ion battery materials

At the Max Planck Institute for Solid State Research in Germany

Chief Scientist Guanglei Cuihas started research on lithium-ion battery materials, systems, and systems

At the QingDao Institute of Bioenergy And Bioprocess Technology, Chinese Academy of Sciences

Chief Scientist Guanglei Cuihas founded the Solid Energy System Technology Center to focus on the development and research of solid-state lithium batteries and systems

Under the leadership of Chief Scientist Cui Guanglei, the QingDao Institute of Bioenergy And Bioprocess Technology, Chinese Academy of Sciences, has establishedthe first large-scale lithium battery test production line. Simultaneously, it has actively embarked on exploring the scale production and process system of solid-state lithium batteries.

The internationally original research on "Hardness with Softness" solid polymer electrolytes has been granted national patent authorization

and applied for PCT international patents. It has now received European authorization, covering key countries such as the United Kingdom, France, Germany, Japan, and the United States

The QingDao Institute of Bioenergy And Bioprocess Technology, Chinese Academy of Sciences has completed the construction of a polymer solid-state lithium battery production line with an annual capacity of 200MWh

Solid-state lithium batteries were taken to the Mariana Trench

to provide power for the "Wanquan" lander

at its maximum working depth of10,901 meters, successfully completing the full deep-sea demonstration application

• The high-performance solid-state battery system returned to the Mariana Trench

• Providing energy power for the "Tianya," "Haijiao," and other full-depth landers

• A total of 34 operations were completed

• With a maximum dive depth of10,918 meters

• The longest single dive operation lasted26 days, setting a world record for the longest continuous operation

The low-power, long-endurance solid-state battery system

conducted a continuous deep-sea demonstration operation for198 days

laying the technical foundation for long-duration deep-sea power supply

The high-energy-density solid-state lithium battery system for all-ocean-depthsprovided full power for the "Canghai" video lander

and high-power, long-endurance energy for the "Luling" multi-site lander.

• The newsolid-state lithium batteryhas completed the national key research and development program

• achievingachieving a 11,089km validation for on-board batteries（NEDC)

• and has completed the development and delivery ofover 110batches of deep-sea power systems

The delivery of a 1MWh deep-sea energy storage base station has been completed

and Hytzer Energy Co.,Ltd. has been formally established

with a contract signed to settle in the Wujin National Hi-Tech Zone, Changzhou City, Jiangsu Province, China

Hytzer Energy Co.,Ltd. has officially started construction

with a total investment of 1 billion yuan and a planned land area of 100 acres
