Institute of Bioenergy and Process, Chinese Academy of Sciences recently released information that the Qingdao Energy Storage Center Cui Guanglei team developed "Green I can" solid-state lithium battery system, with the Chinese Academy of Sciences expedition team went to the Mariana Trench TS03 voyage Division Test tasks for the "Wanquan" abyss lander control system and CCD sensors to provide energy, successfully completed the demonstration of 10,000 meters deep sea applications.
This indicates that our country has completely broken through the bottleneck of Haishen Power Technology, mastered the core technology of Haishen Power System, and became the second country in the world that succeeded in using Haishuhen Lithium Secondary Battery Power System after Japan.
During the mission, the "Wanquan" abyss lander, which uses solid-state lithium batteries, completed a total of 9 diveings at a depth greater than 7,000 meters, of which 6 were over 10,000 meters and the maximum working depth was 10,901 meters and the total underwater working time was 134 hours. Maximum continuous working time of up to 20 hours.
It is understood that large-capacity solid polymer lithium battery "Green I" energy density over 250 watt hours / kg, 500 times the capacity to maintain more than 80%, in many occasions such as acupuncture and extrusion to maintain the harsh test conditions Good safety performance. It can meet the requirements of long life and high safety of the deep-sea submersibles and can provide sufficient energy power for the deep-sea space station under the country's vigorous development.
In addition, "Green can II" has also been successfully developed, the energy density of up to 300 watt hours / kg, is 2 times the liquid lithium batteries, silver-zinc batteries 5 times.
