Abstract
The utility model discloses a novel lithium cell belongs to the lithium cell field. It includes stainless steel shell (1), install group battery (2) of stainless steel shell (1) intracavity and with panel (3) of group battery (2) riveting or screw connection, seted up explosion -proof pressure release on panel (3) and inspected mouthful (4). The utility model discloses under the combined action that stainless steel shell and explosion -proof pressure release were inspected mouthful, can reach and avoid leading to because of battery internal pressure is too big the casing breakage to send the condition that piece and inside electrolyte splash effectively, the inside pressure of reduction battery that can begin again, thereby the security of lithium cell has been strengthened, the mouth is inspected waterproof to explosion -proof pressure release, the inside pressure that appears when unusual of lithium cell can be released to the dirt -proof while, prevent the fried effect that the scattering appears of splitting of whole shell, and the effect of checking the window of bearing at ordinary times.
Description
Technical field
The utility model relates to a kind of lithium battery, particularly relates to a kind of stainless steel casing that adopts and coordinates explosion-proof relief inspection door can carry out the novel lithium battery being mainly used in electric motor car protected when occurring abnormal.
Background technology
Along with new forms of energy product popularizing further in life, be that the battery technology of new generation of representative will inevitably replace heaviness with lithium battery, energy density is low, heavy-polluted old lead-acid battery technology.Lithium battery is generally use lithium alloy metals oxide to be positive electrode, and graphite is negative material, uses the battery of nonaqueous electrolyte.If lithium ion battery is with lithium ion polymer battery.
Existing lead-acid battery and the large portion of lithium battery adopt split design (as battery of electric vehicle), and carry inconvenience; When high building many and charging interval is long, mobile charging demand is increasing, but charges in domestic environment, and people wish safer, needs to carry out specialized designs to this.
Utility model content
The object of utility model is to provide a kind of safe, the situation that can effectively avoid the existing plastic shell of lithium battery housing that fragmentation causes under the effect of internal pressure and electrolyte inside to splash, and insulation, against shock and protecting against shock protected effect and the good novel lithium battery of Portable belt.
In order to realize the purpose of this utility model, the technical scheme that the utility model adopts is: a kind of novel lithium battery, the panel that it comprises Stainless Steel Shell, is arranged on the battery pack in stainless steel case body cavity and is fixedly connected with battery pack; Described panel offers explosion-proof relief inspection door.Under the acting in conjunction of Stainless Steel Shell and explosion-proof relief inspection door, can either effectively avoid causing housing fragmentation to cause the situation of fragment and electrolyte inside splashing because cell internal pressure is excessive, the pressure of the reduction inside battery that can start again, thus enhance the fail safe of lithium battery.
In order to prevent moisture and dust from entering lithium battery body interior from explosion-proof relief inspection door, explosion-proof relief inspection door being stamped there is the strong silica gel lid of sealing.Explosion-proof relief inspection door can discharge pressure when lithium battery interior occurs abnormal while waterproof and dustproof, prevents whole shell from bursting the effect occurring scattering, and is bearing the effect checking window at ordinary times.
In certain embodiments, the whole inwall of described Stainless Steel Shell is all pasted with one-side band glue highland barley paper.
In order to strengthen the vibration resistance of this lithium battery, bottom described Stainless Steel Shell and between battery pack, be provided with double-sided belt glue foam tape.
In certain embodiments, described one-side band glue highland barley paper is also pasted onto between described double-sided belt glue foam tape and described battery pack.Further enhancing the insulating properties of lithium battery.
In order to strengthen insulation and the protecting against shock of this lithium battery, between the surrounding of battery pack described in this lithium battery and described Stainless Steel Shell, be filled with foam gap filler.Foam gap filler had both played the effect of protection battery pack, also as pressure release passage, can coordinate Stainless Steel Shell and explosion-proof relief inspection door quick pressure releasing, thus further enhancing the fail safe of lithium battery simultaneously.
In certain embodiments, described battery pack is made up of at least one lithium cell and baffle, and lithium cell and baffle reinforced support are assembled into.Enhance the stability of lithium cell core.
In order to the insulation strengthening this lithium battery is thought, lithium cell described in this lithium battery is wrapped with high-temperature insulation adhesive tape; The both positive and negative polarity both sides of described lithium cell are coated by insulating protection.
For the ease of charging, carry and carry, described in this lithium battery, panel is also installed with handle.
