Problems solved by technology
But this method has great limitations: light and thin is the development trend of batteries, and it is impossible for batteries to increase indefinitely. We can only increase the energy density of batteries without increasing the volume. However, the current large capacity, high The production technology of energy density batteries has not yet made more breakthroughs
How to make the battery have more charge and discharge times under the condition of the existing technology without increasing the volume is rarely explored
However, no relevant reports have been found so far

Embodiment Construction
[0016] Reference figure 1 . When the battery core is packaged, a width of 1.85mm is reserved inside the effective package area on the side. When the cycle performance of the battery cell cannot meet the requirements of use, use a small cone or a small drill to penetrate a 0.8mm diameter injection port at a place with obvious marks on the packaging film, and use a syringe to inject 0.75ml of anhydrous electrolyte The solution is injected into it, and after the electrolyte solution is fully infiltrated, the liquid injection port is blocked with a sealant that can be assimilated into a film. After refilling, the battery capacity can be restored to about 80% of the nominal value.
[0017] It is understandable that only part of the implementation of the soft-packaged lithium-ion battery with the new packaging structure of this invention is given in this specification. Based on the foregoing principles, the present invention can also make appropriate changes and modifications to th...

Abstract
The invention belongs to the field of lithium ion batteries and particularly relates to a reusable lithium ion battery and a realization method thereof. The reusable lithium ion battery comprises a shell and a battery cell packaged in the shell, wherein a cavity is formed between the shell and the battery cell, is 1-3mm in width and is located above or below the battery cell or on the left or right of the battery cell. The realization method comprises the steps of: firstly, drilling an electrolyte injection port with the diameter of 0.5-2mm in the shell, corresponding to the cavity, and then injecting a certain quantity of electrolyte through the electrolyte injection port; and finally, sealing the electrolyte injection port with sealant. The invention develops a new way, and although the method is simple and convenient, an effect for recovering the capacity of the lithium ion battery is obvious.
Description
Technical field [0001] The invention belongs to the field of lithium ion batteries, and more specifically relates to a reusable lithium ion battery and an implementation method. Background technique [0002] In some electronic products such as mobile phones, MP3s, and digital cameras, the battery is one of the most important components. When the battery starts to age, it generally shows that the display voltage is basically normal when there is no load, and the battery power indicator is basically full, but the standby time becomes shorter; when charging, it will quickly display that the battery is fully charged, but the power will be quickly consumed Exhausted. At this time, the battery has basically been declared obsolete, and its service life often determines the life of the product at the same time. [0003] In order to solve this problem, people are working hard on how to improve the battery capacity: the same number of times of charging and discharging, the same capacity re...
