CAP ASSEMBLY OF SECONDARY BATTERY

摘要

PURPOSE: A cap assembly of a secondary battery is provided to enlarge the electric capacity by using an inductive adhesive proportional to an inner temperature. CONSTITUTION: A cap assembly of a secondary battery comprises a through hole(23b), a current interception plate, and a cap(21). The through hole is formed at a center portion of the cap assembly. The current interception plate is connected with a positive electrode plate(26) of the secondary battery. The cap is connected electrically to the current interception plate. The current interception plate comprises an upper plate(23c) and a bottom plate(23a). The upper plate is connected electrically with the bottom plate. The bottom plate is connected electrically with the positive electrode plates. The upper plate is connected electrically with the cap. The upper plate and the bottom plate are connected electrically with a conductive adhesive. A resistance value of the conductive adhesive is proportional to an inner temperature.
