Embodiment 1

[0031] see figure 1 As shown, a capsule 102 is fixedly arranged in the casing of the cell body 101 of the battery in this embodiment, and a certain liquid is sealed and encapsulated in the capsule 102 .

[0032] As an illustration of this embodiment, for example: the electrolyte solution can be sealed in the capsule, so that after a certain period of time, when the capacity of the battery decays, the user can squeeze the capsule 102 in the casing, so that the electrolyte solution in the capsule 102 can be replenished. Into the battery core body 101, it participates in the electrolysis reaction, replenishes new electrolyte solution for the lithium-ion battery, restores the capacity of the lithium-ion battery, restores and improves the cycle performance of the battery.

[0033] As another illustration of this embodiment, the flame retardant and insulating agent can also be sealed in the capsule. When the battery is abnormal during application, the user can pierce the capsule to ...

Embodiment 2

[0038] see figure 1 As shown, this embodiment provides a lithium-ion battery, which differs from Embodiment 1 mainly in that: a dust-free cloth layer is also provided in the electric core body of this embodiment, and the dust-free cloth layer is located on the battery cell. Any position inside the core 101.

[0039] During preparation, according to the type of the battery core body 101, a dust-free cloth is placed in the battery core body 101, and then the battery core body 101 is placed inside the casing 103, the casing 103 is packaged, the electrolyte solution is injected, formed, separated To obtain the battery of this embodiment.

[0040] In this embodiment, when the electrolyte is injected, the electrolyte is soaked into the core body 101, and the electrolyte penetrates into the core body 101 and is absorbed by the dust-free cloth, thereby increasing the amount of electrolyte in the limited housing 103. Compared with the existing technology, it can improve the capacity ...

Abstract

The invention relates to the field of lithium ion batteries and discloses a lithium ion battery with a capsule. The lithium ion battery comprises a battery core body and electrolyte which are packaged in a shell, wherein the battery core body comprises separation membranes, positive pole pieces and negative pole pieces; each separation membrane is arranged between any positive pole piece and any negative pole piece; an inner cavity of the shell is fully filled with the electrolyte; the electrolyte immerses the battery core body and penetrates into the battery core body; second electrolyte is packaged in the capsule and the capsule is fixed inside the shell and is located outside the battery core body.

Description

technical field [0001] The invention relates to the field of energy, in particular to a lithium ion battery with capsules. Background technique [0002] Lithium-ion battery, as a new energy source, has been widely used in various electronic devices and automobiles due to its advantages of environmental protection, recyclability, small size and portability, and has become one of the most widely used energy sources at present. [0003] The inventor finds in carrying out the research process of the present invention, there is following defective in prior art: [0004] After a certain period of time in the current lithium battery, the internal electrolyte will gradually decrease, resulting in a decline in the cycle performance of the lithium ion battery. Contents of the invention [0005] One of the objectives of the embodiments of the present invention is to provide a lithium-ion battery with a capsule, and the application of this technical solution is beneficial to improve ...
