Embodiment Construction

[0024] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0025] Such as figure 1 , figure 2 and image 3 As shown, the storage battery includes a square body 1 made of plastic material, wherein a positive terminal 5 , a negative terminal 6 and an explosion-proof valve 7 are arranged on one short side of the body 1 . The positive terminal 5 and the negative terminal 6 are connected to the inner plate, and the polarity can be reversed according to the actual situation. Explosion-proof valve 7 plays the role of exhaust here. When the internal air pressure of the battery reaches a certain value, the explosion-proof valve 7 will automatically open to exhaust, thereby preventing the inside of the battery from exploding due to excessive air pressure.

Abstract

The invention provides a storage battery which belongs to the technical filed of machinery and is used for solving the problems of poor heat conductive effect, short service life and the like of the prior storage battery. The storage battery comprises a body in a square shape; one of the short side faces of the body is provided with a positive terminal and a negative terminal; two long side faces of the body all extend outward to form edges; one surface is provided with a high salient point and a low salient point; and the height of the high salient point is larger than that of the lower salient point, and the height of the high salient point is in the same level of the edges. The storage battery has the advantages of good heat conductive effect and long service life.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a storage battery. Background technique [0002] With the development of hybrid motorcycles, automobiles and electric tools, the high-current charge and discharge performance of batteries used on them (including lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries, polymer batteries, etc.) While presenting new challenges, it is becoming more and more important to control the heat conduction of the battery, including the cooling of the battery during work and the heating and heat preservation of the battery at low temperatures. When the battery is charged and discharged with high current, the temperature rise is relatively large. After the temperature rises, it will be a big test for the diaphragm inside the battery. As the temperature rises, the micropores of the diaphragm continue to shrink irreversibly, resulting in shortened b...
