Increasingly favored by consumer in pond.Battery is typically carried out when being charged by way of series connection, so charging
Larger charging current can be there is in journey in whole series battery.When overcharging occurs in set of cells, the voltage of battery can be with
The increase of polarization and rapidly rise, and cause the fast decoupled of battery electrolyte inside.Decomposing phenomenon can discharge great heat
Amount and a large amount of gases, sharply increase the intrinsic pressure of battery, finally produce the phenomenon of battery explosion.Go out during in order to avoid over-charging of battery
Existing explosion phenomenon, can typically arrange explosion-protection equipment in existing rechargeable battery, what is produced during using over-charging of battery intrinsic pressure backs down
Proof assembl, and make gas discharge cell body from steam vent.However, traditional proof assembl has two significant deficiencies.Its
One, traditional explosion-protection equipment, by the continuous increase of air pressure in battery body, makes explosion-proof typically using the realization of formula exhaust structure is burst
Piece ruptures at explosion-proof trace, so as to realize the discharge of gas.However, being limited by manufacturing process and explosion-proof trace position, burst disk
Fracture pressure be difficult precise control, the pressure that can be born so as to cause explosion-protection equipment is also not quite similar, and makes the exhaust pressure of battery
Power differs greatly.Second, the pressure of explosion-proof trace fracture by machining accuracy affected greatly, be easy to occur in process because
Explosion-proof trace is too deep or excessively shallow and cause the pressure at expulsion in battery body too small or excessive, so as to it is difficult to ensure that battery quality is stablized
Property.Therefore, how to guarantee the stabilisation of pressure at expulsion in battery body, be the significant technology issues of current rechargeable battery processing.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided one kind can improve pressure at expulsion in battery body
The battery explosion-proof cap for staggeredly piercing through aerofluxuss of stability.
What goal of the invention of the present utility model was realized in：A kind of battery explosion-proof cap for staggeredly piercing through aerofluxuss, including
