CAN TYPE SECONDARY BATTERY AND MANUFACTURING METHOD OF CIRCUIT BOARD FOR SECONDARY BATTERY |
摘要 |
A can type secondary battery and a method of manufacturing a circuit board for the secondary battery that improves reliability by providing a consistent breakdown pressure of the circuit board used in the can type secondary battery. The can type secondary battery includes an electrode assembly, a can to house the electrode assembly and a cap assembly combined with the can. The cap assembly includes a circuit board, which includes fiber layers and is broken by a safety vent when an internal pressure of the can is increased. A woven direction of the fiber layers is inclined with respect to a length direction of the circuit board. Distribution of the breakdown pressure among the circuit boards is decreased, and thus the circuit boards are broken under a consistent pressure, thereby improving the reliability of the can type secondary battery. |
