Description
Technical field
Technical field of lithium batteries is the utility model is related to, more particularly to a kind of new column type lithium cell.
Background technology
In all energy forms, electric energy be easiest to use, most clean environment firendly and the efficiency highest energy.Battery is most
The device of good storage electric energy.In all battery products, lithium battery be at present in the world most young the history of 21 years (only),
The maximum energy products of most advanced, technology gold content highest, energy density, it is widely used among electric car.
However, due to phenomena such as local corrosion, damage, breakdown occur for lithium battery base material so that lithium battery occurs spontaneous combustion and showed
As not only battery is easy, and can be to producing certain threat with the product of lithium battery and user, therefore there is an urgent need to improve
The security performance of lithium battery.
Utility model content
Based on this, it is necessary to for current lithium battery security performance it is not high the problem of, there is provided a kind of novel lithium battery.
A kind of new column type lithium cell, including battery core and wrap up successively from the inside to the outside the battery core seal aluminum plastic it is compound
Film and protecting crust, foamed plastic plate is provided between the seal aluminum plastic composite membrane and the protecting crust, is set on the protecting crust
It is equipped with some heat emission holes being evenly distributed.
In one of the embodiments, the rounded profiles uniform distribution of the heat emission hole.
In one of the embodiments, the protecting crust is made up of aluminium alloy.
Above-mentioned new column type lithium cell, due to be additionally provided with outside the new column type lithium cell of lithium battery foamed plastic plate and
Protecting crust, therefore, when by hitting, protecting crust has certain protective action, when hitting great efforts, due to foaming
Plastic plate has certain elasticity, can be with the impulsive force of buffering collision of closed, so as to avoid battery core from sustaining damage；If protecting crust offers
Dry heat emission hole, the good heat dispersion of battery can be maintained, avoid reducing because adding protecting crust and foamed plastic plate scattered
Hot property.
Brief description of the drawings
Fig. 1 is the structural representation of the new column type lithium cell of one of embodiment.
Embodiment
To enable above-mentioned purpose of the present utility model, feature and advantage more obvious understandable, below in conjunction with the accompanying drawings to this
The embodiment of utility model is described in detail.Elaborate many details in order to abundant in the following description
Understand the utility model.But the utility model can be to be much different from other manner described here to implement, this area
Technical staff can do similar improvement in the case of without prejudice to the utility model connotation, therefore the utility model is not by following public affairs
The limitation for the specific embodiment opened.
As shown in figure 1, a kind of new column type lithium cell 10, including battery core 110 and wrap up battery core 110 successively from the inside to the outside
Seal aluminum plastic composite membrane 140 and protecting crust 120, be provided with foamed plastic between seal aluminum plastic composite membrane 140 and protecting crust 120
Plate 130, some heat emission holes 121 being evenly distributed are provided with protecting crust 120.
Above-mentioned new column type lithium cell 10, due to being additionally provided with foamed plastic outside the new column type lithium cell 10 of lithium battery
Plate 130 and protecting crust 120, therefore, when by hitting, protecting crust 120 has certain protective action, hits great efforts
When, because foamed plastic plate 130 has certain elasticity, can with the impulsive force of buffering collision of closed, so as to avoid battery core 110 by
Damage, so as to enhance security performance；Protecting crust 120 offers some heat emission holes 121, can maintain the good radiating of battery
Performance, avoid reducing heat dispersion because adding protecting crust 120 and foamed plastic plate 130.
In one of the embodiments, 121 rounded profiles uniform of heat emission hole is distributed.
In one of the embodiments, protecting crust 120 is made up of aluminium alloy.
In one of the embodiments, battery core 110 includes positive terminal 111, top cover 113, upper epiphragma 115, bed die 114 and just
Pole bag 112,140 1 cavitys of top cover 113 and seal aluminum plastic composite membrane, positive terminal 111 are located at chamber central, fill and set in cavity
It is equipped with positive pole bag 112.For example, upper epiphragma 115 is arranged between positive pole bag 112 and top cover 113, bed die 114 is arranged at sealed aluminum
Mould between composite membrane 140 and positive pole bag 112.For example, it is installed with hole among upper epiphragma 115.One is directly set above positive pole bag 112
The larger upper epiphragma 114 of individual area gets lodged in carbon particle in seal aluminum plastic composite membrane 140 and bed die 114, has just reached anti-blocking
The effect that particle jumps out.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
