Storage medium.When battery storage electric energy, electric energy is filled with the storage medium in battery by charger；When electric appliance, in battery
Storage medium electric energy is released.For storage medium when being filled with, discharging electric energy, electric current can promote interior molecules to generate heat.
When battery charge time is too long or excess load is filled with, discharges electric energy, molecule strenuous exercise is generated huge in storage medium
Heat can be more than the critical point of storage medium bearing temperature variation, and the molecular structure of high temperature storage medium allows storage medium
Deformation occurs and qualitative change burning；Battery catches fire occurs, explodes, cause casualties, the major accident of property loss.This problem
So far it is not properly settled.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of rechargeable battery that can be explosion-proof,
When charging and discharging of the present invention, deformation occurs and qualitative change lower than storage medium for the heat that internal storage medium molecular motion generates
Critical-temperature on fire will not explode.After solving existing charge and discharge battery overwork, storage medium high temperature causes qualitative change,
The problem of on fire, explosion, casualties, property loss occurs.To achieve the above object, the present invention provides following technical sides
Case: a kind of explosion-proof rechargeable battery, including positive and negative electrode, memory metal, storage medium, shell.It is known that memory metal is one
Kind alloy.A kind of shape can be arbitrarily made in it in lower temperature, can become original shape again again after then heating, and had
There is Memorability, therefore is referred to as " memory metal ".Memory metal is elongate in shape, a fixation in the explosion-proof rechargeable battery of the present invention
On the positive or negative electrode of battery, other end is not fixed freely, and the temperature of storage medium can be passed directly to remember by electrode
Metal strip.Memory metal item is processed into straight state under the critical point temperature on fire lower than storage medium deformation, is then existed
Memory metal item is bent in room temperature, the degree of bending is controlled when explosion-proof rechargeable battery works or charges, memory metal item
Bending protrusion part can normally contact electric appliance or the corresponding electrode of charging unit；After the technical program, explosion-proof rechargeable battery
In charging and work, once excess load, when the critical point temperature that the fever of internal storage medium is burnt close to deformation, high temperature passes through
Electrode passes to memory metal item, and straight shape is restored in the bending part of memory metal item at once.Straight memory is become by bending
Metal strip be detached from the contact of electric appliance or charging unit counter electrode, it is breaking with the counter electrode of contact.Explosion-proof after open circuit is filled
Battery stops working with the charge and discharge of electric appliance or charging unit, and storage medium temperature is begun to decline.When temperature falls to room temperature
Afterwards, memory metal item restores curved shape.Continue to contact electric appliance or charging unit counter electrode, explosion-proof rechargeable battery in bending part
