Abstract
The utility model discloses a collector ring of a high-capacity cylindrical lithium-ion battery, which is similar to be T-shaped. A covering belt and a pole belt are designed in integral connection; the covering belt is perpendicularly located above the T-shaped transverse direction of the collector ring and is bent outward; and a positioning hole is located in the middle of the T-shaped transverse design of the collector ring. The collector ring simplifies the production process, easily arranges and welds a tab, improves the welding quality of the tab, and solves the problem of the firm connection between an electric core and the collector ring simultaneously.
Description
Technical field
The utility model relates to big capacity column lithium ion battery collecting ring technology.
Background technology
The lithium iron cell current-collector ring generally is applied to big capacity column lithium ion battery internal structure design more, such as diameter 38mm and above column lithium ion battery, is used to connect lug and pole, and its effect is turn-on battery inner pole piece and outside pole intercolumniation electric current.Mostly existing lithium iron cell current-collector loop technique shape is circular (the latter half that similar circular water tumbler transverse cross-section parallel is blocked) and square (the latter half that similar square shape paper shell transverse cross-section parallel is blocked).During the lithium ion battery assembling; Collecting ring is placed on center, electric core end; Be fixed on collecting ring edge after will being distributed in the lug arrangement of cylindrical electric core end afterwards, adopt laser-beam welding machine that lug and collecting ring are welded as a whole again, the collecting ring bottom is connected with utmost point band one end employing welding manner simultaneously; The utmost point band other end is welded in the lithium ion battery pole bottom, through connection conducting inside lithium ion cell, the foreign current of lug, collecting ring, utmost point band and pole.Big capacity column lithium ion battery lug number is more; Tens do not wait to up to a hundred; And mixed and disorderly the arrangement, the random collecting ring edge that is distributed in arrangement back, there are problems such as welding sequence is loaded down with trivial details, production efficiency is lower, lug welding quality consistency difference in above-mentioned technology.In addition, lug directly is fixed on the collecting ring, and is stable inadequately, and when battery used under vibration environment, lug was prone to be torn, and causes battery to damage.
The utility model content
To the problem that above-mentioned lithium iron cell current-collector ring exists in the battery production technological operation, the utility model provides a kind of simplifies production process, be easy to lug arrangement welding, improve the lug welding quality, electric core is technological with the collecting ring that collecting ring firmly is connected.
The technical scheme that the technical problem that the utility model will solve is taked is: said collecting ring is a class tee T design; Comprise utmost point band, coat band, location hole; Said coating band is that an integral body is connected design with utmost point band; Coat band and vertically be positioned at directly over the collecting ring T-shaped transverse design place, be outer bending, said location hole is positioned at collecting ring T-shaped transverse design middle.
When the utility model is applied to the inside lithium ion cell component-assembled, earlier collecting ring is placed on center, electric core end; It is aerial to put into the coating strap clamp after the lug arrangement, after 2 coating band left and right sides are clamped, adopts laser-beam welding machine to coat and is with and the lug firm welding; Simultaneously, collecting ring T-shaped vertical end tail place is welded in the pole bottom; Electricity core pad protrusion is in the location hole place and passes, and makes being connected firmly of electric core and collecting ring; Above-mentioned connection can be accomplished firm assembling and the electric in-core of electric core and collecting ring, the conducting of foreign current.
The utility model can be used as lithium ion cell positive and the design of negative pole currect collecting ring, the anodal general aluminum alloy materials that adopts, and negative pole generally adopts copper or the nickel material.Usually, material monolithic thickness is 0.2-1.2mm; The vertical design width of T-shaped is 4-15mm, and length is 20-100mm; T-shaped transverse design width is 4-20mm, and length is 8-25mm; The coating strip length is 8-40mm, and length is 4-20mm after the bending, and coating band highly is 4-12mm.
The beneficial effect of the utility model is: adopted the tee T collecting ring and coated the band global design, for the tee T design part, replaced that collecting ring and utmost point tape welding connect back part in the existing technology, omitted welding sequence, improved production efficiency; For coating the band design; When lithium ion cell polar ear arrangement, welding sequence operation; The coating strap clamp is aerial with putting into after the lug arrangement, only needs to coat about the welding collecting ring to be with two places, significantly reduces and has welded operation; Improved welding efficiency, the inconsistent problem of the welding quality of having avoided multiple welding to cause simultaneously; And the design of location hole makes more firm being connected of electric core and collecting ring, pulls apart the generation of lug phenomenon when having avoided battery under vibration environment, to use.
