Description

A lithium battery panel for preventing lug corrosion

Technical Field

The utility model belongs to the technical field related to lithium battery panels, and particularly relates to a lithium battery panel capable of preventing tab corrosion.

Background Art

Tabs are a raw material for lithium-ion polymer battery products. For example, mobile phone batteries, Bluetooth batteries, laptop batteries, and automotive power batteries in our daily lives all require tabs. Batteries are divided into positive and negative poles, and tabs are metal conductors that lead the positive and negative poles out of the battery core. In layman's terms, the tabs at the positive and negative poles of the battery are the contact points during charging and discharging. Therefore, in order to avoid damage to the tabs during storage, the lithium battery needs to have a structure that protects the tabs.

However, the protection structure used in the existing lithium battery panels mostly adopts an integrated structure. Therefore, when the protection structure is damaged, it cannot be replaced in a single piece. Therefore, each replacement needs to be replaced as a whole, which increases the replacement cost. At the same time, since the inside of the protection structure cannot be kept dry, the tabs of the lithium battery are easily corroded when stored for a long time. To this end, we provide a lithium battery panel that prevents tab corrosion to solve the above problems.

Utility Model Content

The utility model aims to provide a lithium battery panel for preventing electrode ear corrosion. By respectively putting a plurality of protective covers on different electrode ears, a single pair of protective covers can be replaced. At the same time, the placement frame and the drying belt are used in coordination to keep the interior of the protective cover in a dry environment, thereby preventing the electrode ears from being corroded.

In order to solve the above technical problems, the utility model is realized by the following technical solutions:

The utility model discloses a lithium battery panel for preventing electrode ear corrosion, comprising a lithium battery body; two symmetrically arranged electrode ears are fixed on the upper end surface of the lithium battery body, protective sleeves are sleeved around the electrode ears, placing frames are slidably arranged inside the protective sleeves located on the end surfaces of the electrode ears, and drying bags are arranged inside the placing frames.

The utility model is further configured that the front and rear surfaces of the lithium battery body are provided with sockets at positions corresponding to the electrode ears, and the sockets all penetrate the upper end surface of the lithium battery body.

The utility model is further configured that elastic L-plates are fixed to the lower parts of the front and rear surfaces of the exterior of the protective cover, and the elastic L-plates are respectively plugged into the corresponding internal positions of the sockets.

The utility model is further configured that the opposite surfaces of the two elastic L-plates in the same front-to-back direction are fixed with card strips, the inner surface of the socket is provided with card slots at positions corresponding to the card strips, and the card strips are respectively located in the corresponding card slots.

The utility model is further configured that the left and right side surfaces inside the protective cover are both provided with a string-shaped opening, and the string-shaped opening penetrates the lower end surface of the protective cover.

The utility model is further configured that the left and right end surfaces of the placement frame are fixed with limit blocks that slide in the inner position of the string-shaped opening, and the lower end surface of the placement frame is penetrated by a plurality of through holes distributed in an array.

The utility model is further configured that a string-shaped plate abutting against the limit block is slidably arranged inside the string-shaped opening, and the lower end surface of the string-shaped plate is flush with the lower end surface of the protective sleeve.

The utility model has the following beneficial effects:

When the utility model is in use, a plurality of protective sleeves are respectively sleeved on different electrode ears. Therefore, when the protective sleeve on a single electrode ear is damaged, it is only necessary to remove the protective sleeve from the electrode ear and replace it, thereby reducing the replacement cost.

When the utility model is in use, the protective cover is directly put on the electrode ear position with the lithium battery body, so that the end of the electrode ear is connected to the drying bag, and the environment inside the protective cover is dried by the drying bag, so as to ensure that the inside of the protective cover is in a dry environment, so that the electrode ear is always in a safe environment, and corrosion of the electrode ear is avoided.

Of course, any product implementing the present invention does not necessarily need to achieve all of the above advantages at the same time.
