Abstract
The utility model discloses an ultrathin automobile lithium ion battery which comprises a battery core (1) as well as positive pole and negative pole lugs (2 and 3), wherein one ends of the positive pole and negative pole lugs (2 and 3) are positioned inside the battery core (1), and the other ends thereof are arranged outside the battery core (1); and the ultrathin automobile lithium ion battery is characterized in that the battery core (1) has the thickness of 4-10mm. The ultrathin automobile lithium ion battery has fewer layers, is simpler, reduces the thickness of the whole outer wall, is firmer in adhesive bonding, reduces the work load and the efficiency of construction, and improves the heat preservation and energy conservation effects.
Description
Technical field
The utility model belongs to a kind of lithium battery.Specifically a kind of automobile lithium battery.
Background technology
Because the aggravation gradually of global energy crisis, All Around The World and national government are all being advocated energy-conserving and environment-protective, exploitation green fuel and new forms of energy.The high capacity cell that is applicable to electric bicycle, battery-operated motor cycle, electric automobile becomes the focus of researching and producing just gradually.And in comparatively ripe at present battery, lithium ion battery with its exclusive specific energy height, have extended cycle life, advantages such as self discharge is little, environmental protection, it is had outstanding performance in new energy field, and wherein large volume automobile more and more is subjected to the attention of national governments with lithium ion battery.But generally between 20.00～50.00mm, high capacity cell is all about the 100Ah battery with lithium ion battery thickness for the automobile of domestic making, and battery is too thick will to cause that radiating effect is bad at work; The radiating effect of battery is bad, and battery the cycle performance variation will occur at work, the temperature of self situation such as will raise gradually, thus can cause reducing battery useful life and poor safety performance, restricting its extensive popularization.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of ultra-thin automobile lithium ion battery of good heat dissipation effect.
The technical solution of the utility model is as follows: 1, a kind of ultra-thin automobile lithium ion battery, comprise battery and positive and negative lug, this positive and negative lug one end is positioned at battery, and the described positive and negative lug other end is positioned at outside the battery, and its key is: described battery thickness is 4～10mm.
Above-mentioned battery is a rectangle.
Above-mentioned positive and negative lug all is arranged on same the limit of battery.
Table one is the experimental test data of different-thickness battery
The result of reference table 1 shows, along with cell thickness be reduced between 4～10mm the time numbering 3～4 discharge capacity of the cell and cycle performance become better and better, the battery surface temperature is more and more lower during discharge and during abuse, security performance promotes obvious more.Dissect the battery after circulating, find that cell thickness is thick more, it is serious more that battery internal layer positive mix and negative pole powder take off material, illustrate that cell thickness is thick more, the high more difficult more diffusion of temperature that internal-response produces when battery charge or discharge, long-term circulation has caused the material that takes off of electrode powder, and cycle performance of battery is just poor more, and powder comes off and causes battery safety poor more.
Beneficial effect: the utility model is with the automobile lithium battery attenuation of conventional 20～50mm, change thickness between 4～10mm, the battery attenuation has increased the area of dissipation of battery, radiating effect is better, cycle performance and security performance have obtained tangible improvement, and have improved greatly the useful life of battery.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, 2, a kind of ultra-thin automobile lithium ion battery of the utility model is made up of battery 1 and positive and negative lug 2,3, and battery 1 is a rectangle, and described positive and negative lug 2,3 all is arranged on same the limit of battery 1.These positive and negative lug 2,3 one ends are positioned at battery 1, and described positive and negative lug 2,3 other ends are positioned at outside the battery 1, and described battery 1 thickness is 4～10mm.
