Background technology
Along with the progress of battery technology, high-power battery is applied more and more extensive in electric automobile and high-performance weaponry.But under high power discharge condition, battery inevitably can discharge a large amount of heat energy, causes internal temperature too high.And battery heat radiation is mainly undertaken by metal shell or block, but the general aluminium material using or the battery container of stainless steel, only an electrode with battery is conducted, and causes the heat radiation of another electrode of battery only can rely on battery electrode column to carry out.Cause thus battery heat radiation insufficient, the heterogeneity of interior temperature distribution, not only greatly affects the performance and used life of power supply under long-term service condition, and can bring very large potential safety hazard.
Summary of the invention
The purpose of this utility model is the cylindrical battery that a kind of housing of redesigning in order to overcome the above-mentioned deficiency of existing battery is divided into two-section, makes the high-power battery of preparation have that area of dissipation can regulate and control, the equal first-class advantage of Temperature Distribution.
The utility model is to rely on following technology to realize: a kind of housing is divided into the cylindrical battery of two-section, it is characterized in that this battery comprises Positive Poles 1, anodal housing 2, anode collection sheet 3, positive pole ear 4, battery core 5, raised type insulating barrier 6 or inner convexed insulating barrier 11, negative lug 7, negative pole currect collecting sheet 8, negative pole housing 9, negative pole pole 10, battery container is divided into two-section, be anodal housing 2 and negative pole housing 9, positive pole and negative pole with battery is conducted respectively, between anodal housing 2 and negative pole housing 9, by raised type insulating barrier 6 or inner convexed insulating barrier 11, be tightly connected, battery core 5 two ends are connected with negative pole currect collecting sheet 8 with anode collection sheet 3 respectively, then are connected with negative pole housing 9 with anodal housing 2 respectively, between anodal housing 2 and negative pole housing 9, be raised type insulating barrier 6 or inner convexed insulating barrier 11, anodal housing 2 and negative pole housing 9 are inserted into respectively the two ends of raised type insulating barrier 6 or inner convexed insulating barrier 11, raised type insulating barrier 6 or inner convexed insulating barrier 11 are all designed with a boss 12 above, and boss 12 is by anodal housing 2 and negative pole housing 9 insulated separation, Positive Poles 1 and anodal housing 2, negative pole pole 10 and negative pole housing 9 are integral type structure.
The material of raised type insulating barrier 6 or inner convexed insulating barrier 11 is pottery, plastics or rubber.
The length ratio of anodal housing 2 and negative pole housing 9 regulates according to the heat production power of battery plus-negative plate.
The cylindrical battery that adopts this structural design to prepare, good heat dissipation effect, Temperature Distribution homogeneous, and can carry out the adjusting of housing according to different working conditions, meet the needs of different service conditions.This cylindrical battery is particularly suitable for design and the preparation of full lug battery, after electric core winding completes, only flow collection sheet need be welded on both positive and negative polarity lug, battery plus-negative plate pole is made of one formula structure with housing respectively, after housing is closely connected with both positive and negative polarity flow collection sheet, with insulating barrier sealing, can obtain being applicable to high power discharge, the outstanding cylindrical battery of radiating effect.
