Document Type and Number:
WIPO Patent Application WO/2002/101868
Kind Code:
A1
Abstract:
The invention relates to a storage battery resistant to pressure and beneficial to environmental protection, which is suitable for being used in deep sea. The storage battery uses a case, the wall of which is thicker than that of an ordinary case, but thinner than that of a storage battery case having resistance to pressure to some extent. The storage battery contains a liquid low-sodium silicate electrolyte, which is both a electrolyte and a forming solution, and manufactured by magnetization process. A self adjustable-pressure part is mounted on the top of the upper lid plate of the battery. The storage battery is able to operate at the depth of 6000 meters below sea level. A storage battery has a specific energy of 53W/kg or more and the service life of the storage battery increases to 400 times or more. The storage battery has resistance to low and high temperature and operates normally at the temperature of -50°C$m(k)+60°C. The start power increases from 3-7C discharge capacity to 30C discharge capacity. The battery has extremely low self-discharge and can operate normally after being stored for 18 months. There is provided a new power source for exploring in sea, national defense and communication.
