Embodiment

[0007] In an embodiment, the explosion-proof rechargeable battery is loaded into the battery car. Since the positive electrode of the battery is equipped with a memory metal strip, the curved part of the memory metal bar contacts the corresponding negative pole of the battery car; the battery car works normally when the switch of the battery car is turned on. Check the safety and reliability of explosion-proof rechargeable batteries: artificially overload the battery to output a large current, and use a screwdriver to short-circuit the positive and negative poles of the battery car battery. After the battery is short-circuited, the high current causes the storage medium to heat up to a temperature lower than the critical point of fire deformation, and the high temperature makes the memory metal strip on the positive pole of the battery instantly recover its straight shape. When the negative pole of the battery car is out of contact, the battery stops working and the temperature ...

Abstract

The invention discloses an anti-explosion rechargeable battery which is prepared from positive and negative electrodes, memory metal, an accumulation medium and a shell, wherein the memory metal is ofa strip shape, with one end fixed on the positive or negative electrode of the battery, and the other end is free; the temperature of the accumulation medium can be directly transferred to the memorymetal strip through the electrode. In the technical scheme, when the anti-explosion rechargeable battery is charged and works, once the heat of the accumulation medium inside approaches the criticalpoint temperature for deformation combustion, the high temperature is transferred to the memory metal strip through the electrode, the contact between the memory metal strip and corresponding electrode of electrical application or charging device is cut while the circuit with the electrodes of corresponding charging device and electrical appliance is opened. The open-circuit anti-explosion rechargeable battery stops the charging and discharging work on the electrical appliance and the charging device, and the temperature of the accumulation medium starts to drop. When the temperature is reduced to normal temperature, the anti-explosion rechargeable battery continues working. The accumulation medium in the anti-explosion rechargeable battery is ensured to be always kept in a safe and normaltemperature state lower than the critical point, thus the factors leading to fire and explosion caused by long-time overload charging and discharging work of the anti-explosion rechargeable battery and excessively high temperature of the accumulation medium inside over the critical point are avoided.

Description

technical field [0001] The invention relates to an explosion-proof rechargeable battery, in particular to a safe explosion-proof power storage device during charging and discharging. Background technique [0002] Explosion-proof rechargeable battery is a kind of electric storage device that can be charged and discharged. As we all know, batteries are essential equipment for all mobile appliances. Mobile phones, battery cars, electric cars, and tablets are all inseparable from batteries. With the development of society, rechargeable and dischargeable batteries have become an indispensable item in people's daily life. The battery stores electrical energy, and the release of electrical energy depends on its internal storage medium. When the battery stores electrical energy, the charger charges the electrical energy into the storage medium in the battery; when the electrical appliance uses electricity, the storage medium in the battery releases the electrical energy. When th...
