Abstract

The utility model discloses a double-tab core winding body for a lithium ion battery. The double-tab core winding body comprises a plate strip, a first tab and a second tab, wherein the first and second tabs are welded on the plate strip, and are arranged at the two ends of the plate strip respectively. The double-tab core winding body for the lithium ion battery is low in internal resistance and high in safety.

Description

Double-pole lug formula lithium ion battery coil core coiling body
Technical field
The utility model relates to a kind of Double-pole lug formula lithium ion battery coil core coiling body.
Background technology
Existing monopole ear formula lithium ion battery coil core coiling body, owing to only have a lug, internal resistance is large, and it is serious to generate heat during discharge, and fail safe is low, has seriously retrained the discharge performance of lithium ion battery.
The utility model content
Technical problem to be solved in the utility model provides a kind of Double-pole lug formula lithium ion battery coil core coiling body, and this Double-pole lug formula lithium ion battery coil core coiling body internal resistance is little, safe.
The technical solution of utility model is as follows:
A kind of Double-pole lug formula lithium ion battery coil core coiling body comprises pole piece band, the first lug and the second lug; The first lug and the second tab welding are on the pole piece band.
The first lug and the second lug divide the two ends that are located at the pole piece band.
Beneficial effect:
Double-pole lug formula lithium ion battery coil core coiling body of the present utility model owing to adopt the Double-pole lug structure, and two lugs are arranged on the two ends of pole piece band, and are harmonious good, thereby internal resistance is low, during discharge heating little, fail safe is good.
Description of drawings
Fig. 1 is the structure chart (expanded view) of Double-pole lug formula lithium ion battery coil core coiling body of the present utility model.
Label declaration: 11-the first lug, 12-the second lug, 13-pole piece band.
Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
As shown in Figure 1, a kind of Double-pole lug formula lithium ion battery coil core coiling body comprises pole piece band, the first lug and the second lug; The first lug and the second tab welding are on the pole piece band.
