Problems solved by technology

For the electric core with a winding structure, the winding core will be pulled out from the winding body after the winding process is completed, but when the electric core is recycled, if the electric core is to be rewound, since there is no winding core, it will be reversed. The battery cells cannot be fixed during rolling, making it difficult to realize mechanized rewinding, which has caused great difficulties in realizing efficient and automatic recycling of power batteries

Embodiment

[0031] like Figure 1 to Figure 2 As shown, an easy-to-unwind cell structure 100 includes a winding core 10 and a bushing 20 sleeved on the outer peripheral wall of the winding core 10 . The cross-section of the winding core 10 is arranged in a diamond-shaped structure, and the shape of the bushing 20 is adapted to the shape of the winding core 10 to ensure that the inner peripheral wall of the bushing 20 is in close contact with the outer peripheral wall of the winding core 10 to ensure The shape of the winding body of the battery cells 30 formed after the battery cells 30 are wound on the bushing 20 does not change.

[0032] In this way, by covering the outer peripheral wall of the winding core 10 with the bushing 20 immediately adjacent to it, the bushing 20 not only serves as a carrier for the battery cells 30 during winding, but also guides the battery cells 30 during recovery. The rewinding core 40 is quickly inserted into the inner cavity of the bushing 20 , so that th...

Abstract

The invention discloses a battery cell structure easy to unwind, which comprises a winding roll core and a bushing sleeved on the peripheral wall of the winding roll core, the shape of the bushing is matched with that of the winding roll core, and the bushing is provided with an opening for inserting a battery cell into the winding roll core. Through the mode, the lining which is tightly connected with the winding roll core sleeves the peripheral wall of the winding roll core, and the reverse winding roll core can be guided to be quickly inserted into the inner cavity of the lining when the battery cell is recycled, so that the battery cell is subjected to nondestructive separation after being reversely wound, the recovery rate of the battery cell is greatly improved, and the production cost is reduced. And corresponding automatic equipment can be matched to realize full-automatic back-rolling recovery of the battery cell, so that the battery cell back-rolling device has a very high popularization value.

Description

technical field [0001] The invention relates to the technical field of new energy battery recycling, in particular to a battery core structure that is easy to unwind. Background technique [0002] With the deepening of the concept of environmental protection, the new energy industry is developing rapidly around the world. Among them, lithium batteries, as a new energy battery, are gradually being widely used in all walks of life. However, the service life of lithium batteries is limited, and a large number of discarded lithium batteries are produced every year. At the same time, lithium batteries contain a large amount of nickel, cobalt, manganese, lithium and other metal resources. These resources are not abundant in my country and need to be imported from overseas, which is easily restricted by foreign countries. On the other hand, if these heavy metal elements cannot be properly recycled, there is a risk of environmental pollution. [0003] At present, the recycling me...
