Novel square lithium ion battery cover plate

Abstract

The invention discloses a novel square lithium ion battery cover plate. The novel square lithium ion battery cover plate comprises a main body cover plate, wherein a liquid filling hole and two electrode studs are formed in/on the main body cover plate; an electrode stud upper cover plate is arranged at the top of each electrode stud in a sleeving manner; two connecting pieces are arranged at the bottom of the main body cover plate and are connected with the lower parts of the corresponding electrode studs; an explosionproof membrane is arranged at the middle part of the main body cover plate and an explosionproof membrane upper film is arranged at the top of the explosionproof membrane; support upper edges are respectively arranged at two ends of the bottom of the main body cover plate along the length direction; vibration supports are respectively arranged at the two ends of the bottom of the main body cover plate along the width direction, and the bottoms of the vibration supports can support against a battery cell; the vibration supports can be in contact fixation with the support upper edges; the two vibration supports can be in contact fixation; the two electrode studs comprise a positive stud and a negative stud. According to the novel square lithium ion battery cover plate, the vibration resistance of a lithium ion battery is enhanced, and further a series of risks of short circuit, open circuit, quick attenuation of electrical performance inside the lithium ion battery and the like are avoided.

Description

technical field [0001] The invention relates to a battery cover, in particular to a novel square lithium-ion battery cover. Background technique [0002] Lithium-ion batteries have been widely used and popularized in daily life and industry. In recent years, with the strong support of national policies, lithium-ion batteries continue to "heat up" in the field of electric vehicles, and there are more and more lithium-ion batteries as the heart of pure electric vehicles. Lithium-ion batteries have a good prospect. Under this broad prospect, the requirements for lithium-ion batteries are getting higher and higher. It is necessary to develop some lithium-ion batteries specially suitable for electric vehicles. [0003] At present, the lithium-ion battery technology used in electric vehicles is relatively mature, but whether the lithium-ion battery can withstand vibration has a serious impact on the normal operation of the lithium-ion battery, especially in bad road conditions. ...
