Chinese scientific research vessel the Exploration-2, or Tansuo-2, has recently completed its trial deployment of a deep-sea in-situ scientific experiment station. Various types of equipment including a submarine base station, an in-situ laboratory and a glider were involved in the test.

Based on domestic technology, the test achieved the integration of megawatt-hour-level solid-state lithium-metal batteries and its application at a water depth of over 1,000 meters for the first time.
