Embodiment 1

[0035] See figure 1 As shown, this embodiment provides a lithium ion battery, which mainly includes a casing, a battery core, and an electrolyte. Wherein, the electric core body and the electrolyte are encapsulated in the casing, and the electrolyte fills the entire inner cavity of the casing, soaks the whole electric core body, and penetrates into the electric core body. The battery core of this embodiment includes a separator, a positive electrode sheet, a negative electrode sheet, and a dust-free cloth layer. A separator is spaced between any one of the positive electrode sheet and the negative electrode sheet, and the dust-free cloth layer is located at any position inside the battery core.

[0036] During the preparation, according to the type of the battery core body, the dust-free cloth is set in the battery core body, and then the battery core body is placed inside the shell, the shell is sealed, the electrolyte is injected, formed, and the volume is divided. Example of b...

Abstract

The invention relates to the field of lithium ion batteries, and discloses a lithium ion battery provided with non-dust cloths. The lithium ion battery provided with non-dust cloths comprises a casing, a battery cell body and an electrolyte, wherein the battery cell body and the electrolyte are packaged in the casing; an inner cavity of the casing is filled with the electrolyte which soaks the battery cell body and permeates into the battery cell body; and the battery cell body comprises diaphragms, positive plates, negative plates and the non-dust cloths, one diaphragm is spaced between any one positive plate and negative plate, and the non-dust cloths are located in the battery cell body. With the application of the technical scheme, improvement of the cycling performance of the lithium ion battery is facilitated.

Description

Technical field [0001] The invention relates to the field of energy, in particular to a lithium ion battery with a dust-free cloth. Background technique [0002] As a new energy source, lithium-ion batteries are widely used in various electronic devices and automobiles due to their environmental protection, recyclability, small size and easy portability, and have become one of the most widely used energy sources. [0003] During the research of the present invention, the inventor found that the prior art has the following defects: [0004] After the current lithium battery has been cycled for a period of time, the internal electrolyte will gradually decrease, resulting in a decrease in the cycle performance of the lithium ion battery. Summary of the invention [0005] One of the objectives of the embodiments of the present invention is to provide a lithium ion battery, and the application of this technical solution is beneficial to improve the cycle performance of the lithium ion bat...
