SAFETY PLATE OF SECONDARY BATTERY |
摘要 |
In a battery in which a separator is disposed between a cathode and an anode, a jelly roll is wound with the separator. The cathode, the anode and the separator are received in a battery case and surrounded with an electrolyte, and an opening of the battery case is sealed by a top cap assembly connected to the cathode. A curved groove is formed on the battery case as a safety element for preventing the explosion of the battery due to an increase of internal pressure, the groove being formed along a line of equal stress on the surface of the battery case. |
