Estimating the term…
Explosion of rechargeable battery can be prevented in a relatively simple structure, at low cost, and without allowing spouting of electrolyte. A rechargeable battery 100D1 using a pressure-crush type protective device comprises a housing H including an internal electrode plate 120 spirally wound about a positive electrode and a negative electrode through a separator, a jacket 110 for accommodating this internal electrode plate 120, and a sealing body 140 for closing the opening of this jacket 110, a positive electrode (or negative electrode) output electrode 130 connected electrically to the internal electrode plate 120, a spacer 200 disposed beneath the sealing body 140 for insulating between the sealing body 140 and internal electrode plate 120, a pressure-crush type protective device A1 disposed in said spacer 200 as a pressure-sensitive element for detecting the internal pressure in the housing H, and an output terminal 400 connected electrically to one terminal of this pressure-crush type protective device A1 (one end of a conductor layer 210A1) for picking up the detection result of the internal pressure detected by the pressure-crush type protective device A1 electrically to outside, in which other terminal of the pressure-crush type protective device A1 (other end of the conductor 210A1) is connected electrically to the positive electrode (or negative electrode) output electrode 130.
A rechargeable battery using a pressure-crush protective device comprising a housing for accommodating an electrode plate in its inside, a pressure-crush protective device disposed in said housing as a pressure-sensitive element for detecting the internal pressure, an output terminal which is separate from an output electrode of said rechargeable battery disposed in said housing for keeping tightness and insulation for taking out the detection result of the internal pressure detected by said pressure-crush protective device electrically to outside, and a controller which breaks a circuit component if the internal pressure is higher than a specified value.
