Description
Technical field
The utility model relates to the technical field that prevents flexible-packed battery damage, is specifically related to a kind of antisitic defect cylindrical battery.
Background technology
Flexible-packed battery, the shell of its use is aluminum plastic film, is the soft packaging material of quality, its inside is coated with electricityPole piece and electrolyte etc., the flexible-packed battery of complete; Due to the specification difference of flexible-packed battery, need to cut out differenceThe aluminum plastic film covering of size uses, and covering is generally rectangle, the flanging of middle reserved certain width, thenThe left and right sides turns down, and middle flanging just forms the thickness of battery, and the place of both sides turnover overlaps mutually by electrodeThe material such as sheet, electrolyte is coated and wherein forms battery.
Because the shell of flexible-packed battery is aluminum plastic film, its thin thickness, quality is soft, after battery pack installs, removesFortune operating process, is easy to deform, the defect such as scuffing, very easily causes the leakage of the electrolyte in aluminum plastic film; This utmost pointThe large pollution that has caused battery and the raising of percent defective; In addition, the lug of flexible-packed battery is often by film and plastic-aluminumFilm bonding, isolation, but lug often needs to stretch out a battery body part, and it is quality softness, easily distortionMaterial, cause occurring that lug directly contacts with the aluminum plastic film of battery and the short circuit phenomenon that causes.
Utility model content
The utility model, for the above-mentioned deficiency of prior art, provides one to be difficult for wounded, scuffing, thereby effectively preventsElectrolyte leakage and be also difficult for the antisitic defect cylindrical battery of short circuit.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of antisitic defect cylindrical battery, comprises circleCylindrical battery body, described cylindrical battery body comprises aluminum plastic film covering, in aluminum plastic film covering, be provided with by positive plate,The cylindrical battery core that negative plate, membrane winding form, the two ends of battery core are connected with respectively anode ear and negative electrode lug; Anode earAnd the two ends that are positioned at cylindrical body between negative electrode lug and aluminum plastic film covering are provided with end edge sealing, aluminum plastic film covering and cylinderIn the space that shape battery core forms, be provided with electrolyte, it is characterized in that: the outer peripheral face of described anode ear is provided with anode earConnecting plate (PP material), the outer peripheral face of negative electrode lug is provided with negative electrode lug connecting plate; The outer peripheral face of described aluminum plastic film coveringBe stained with one deck PET film.
Adopt said structure, owing to being stained with one deck PET film at battery body aluminum plastic film covering outer peripheral face, thereby fully protectCard battery is not worn, is out of shape at transport or moving process and scratches and cause the leakage of electrolyte, thereby fully ensures batteryNormal use, prevent the raising of percent defective; The present invention also adopts at the outer peripheral face of anode ear and negative electrode lug and is provided with in additionLug connecting plate, specifically adopts PP material to adopt as insulation, because lug quality is soft and width is narrow, is easy to anti-Raw distortion, deformation, cause with aluminum plastic film covering and contact and cause battery short circuit, and adopt above-mentioned lug connecting plate goodProtection lug, prevents from instead giving birth to distortion, deformation, thereby further ensures its phenomenon that is short-circuited.
As preferably, the thickness of described PET (poly-terephthalic acids second diester) film is 0.05-3mm; Adopt this thicknessCan ensure that inner aluminum plastic film covering is not scratched, simultaneously convenient in the time removing, and raw material consumption is few; Further preferablyFor 0.1-1mm.
As preferably, the fastening length of a film 1-5mm of the Length Ratio lug of described lug; Adopt this structure one to ensure that lug justNormal work, two come also can ensure that lug is not twisted, deformation, cause with aluminum plastic film covering and contact and cause battery short circuit.As further preferred, the fastening length of a film 2-3mm of Length Ratio lug of described lug.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail, but is not limited only to followingEmbodiment.
As shown in accompanying drawing 1-2: a kind of antisitic defect cylindrical battery, comprises cylindrical battery body, described cylindrical batteryBody comprises aluminum plastic film covering 1, is provided with the cylinder being formed by positive plate, negative plate, membrane winding in aluminum plastic film coveringShape battery core 2, the two ends of battery core are connected with respectively anode ear 3 and negative electrode lug 4; Anode ear and negative electrode lug and aluminum plastic film coveringBetween be positioned at cylindrical body two ends be provided with end edge sealing 5, in the space that aluminum plastic film covering and cylindrical battery core formBe provided with electrolyte, it is characterized in that: the outer peripheral face of described anode ear 3 is provided with anode ear connecting plate (PP material)3.1, the outer peripheral face of negative electrode lug is provided with negative electrode lug connecting plate 4.1; The outer peripheral face of described aluminum plastic film covering is stained with one deckPET film 6.
Adopt said structure, owing to being stained with one deck PET film at battery body aluminum plastic film covering outer peripheral face, thereby fully protectCard battery is not worn, is out of shape at transport or moving process and scratches and cause the leakage of electrolyte, thereby fully ensures batteryNormal use, prevent the raising of percent defective; The present invention also adopts at the outer peripheral face of anode ear and negative electrode lug and is provided with in additionLug connecting plate, specifically adopts PP material to adopt as insulation, because lug quality is soft and width is narrow, is easy to anti-Raw distortion, deformation, cause with aluminum plastic film covering and contact and cause battery short circuit, and adopt above-mentioned lug connecting plate goodProtection lug, prevents from instead giving birth to distortion, deformation, thereby further ensures its phenomenon that is short-circuited.
