Description
Technical field
The utility model relates to the battery technology field, particularly relates to a kind of corrosion-resistant liquid-injection equipment of lithium ion battery.
Background technology
At present, advantages such as lithium ion battery has the specific energy height, recycles often, memory time is long, not only on portable electric appts, be used widely, and be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool as mobile phone, Digital Video and laptop computer.
For lithium ion battery, need to carry out the fluid injection operation in process of production, promptly at the inner electrolyte that injects of its battery container, at this time, have corrosive electrolyte and splash easily and volatilize, thereby not only cause corrosion, had a strong impact on the useful life of liquid-injection equipment liquid-injection equipment (as the fluid injection machine), also can't guarantee the consistency of electrolyte that each lithium ion battery injects simultaneously, have influence on the consistency of performance of a plurality of lithium ion batteries of producing.
At present, in order to improve the corrosion resistance of liquid-injection equipment, battery apparatus producer can only purchase corrosion-resistant material and select corrosion resistant sensor production liquid-injection equipment for use, thereby has significantly increased the production cost of lithium ion battery, and the widespread production that has influenced lithium ion battery is popularized.
Therefore, press for a kind of technology of developing at present, its liquid-injection equipment that can prevent lithium ion battery is corroded by electrolyte in the fluid injection process, guarantee the useful life of liquid-injection equipment, needed liquid-injection equipment production cost is low simultaneously, thereby reduced the production cost of lithium ion battery greatly, the widespread production that helps lithium ion battery is popularized.
The utility model content
In view of this, the purpose of this utility model provides a kind of corrosion-resistant liquid-injection equipment of lithium ion battery, its liquid-injection equipment that can prevent lithium ion battery is corroded by electrolyte in the fluid injection process, guarantee the useful life of liquid-injection equipment, needed liquid-injection equipment production cost is low simultaneously, thereby reduced the production cost of lithium ion battery greatly, the widespread production that helps lithium ion battery is popularized, effectively improved the market competitiveness of lithium ion battery, be of great practical significance.
For this reason, the utility model provides a kind of corrosion-resistant liquid-injection equipment of lithium ion battery, and described liquid-injection equipment housing is provided with protecting film.
Wherein, described liquid-injection equipment inner walls is provided with described protecting film.
Wherein, described protecting film sticks on the described liquid-injection equipment inner walls.
Wherein, described protecting film is a polyimide film.
The technical scheme that is provided by above the utility model as seen, compared with prior art, the utility model provides a kind of corrosion-resistant liquid-injection equipment of lithium ion battery, its liquid-injection equipment that can prevent lithium ion battery is corroded by electrolyte in the fluid injection process, guarantee the useful life of liquid-injection equipment, needed liquid-injection equipment production cost is low simultaneously, thereby reduced the production cost of lithium ion battery greatly, the widespread production that helps lithium ion battery is popularized, effectively improved the market competitiveness of lithium ion battery, be of great practical significance.
Description of drawings
The partial structurtes simplified schematic diagram of the inwall of the corrosion-resistant liquid-injection equipment of a kind of lithium ion battery that Fig. 1 provides for the utility model;
Among the figure: 1 is the liquid-injection equipment inner walls, and 2 is protecting film.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
The utility model provides a kind of corrosion-resistant liquid-injection equipment of lithium ion battery, and described liquid-injection equipment housing is provided with corrosion resistant protecting film 2.
Referring to Fig. 1, in the utility model, be preferably described liquid-injection equipment inner walls 1 and be provided with described protecting film 2.
On the specific implementation, described protecting film 2 sticks on the described liquid-injection equipment inner walls 1.
In the utility model, on the specific implementation, the protecting film that described protecting film 2 can be made for any one resistant material can be selected according to user's the needs and the needs of battery production producer.
In the utility model, on the specific implementation, described protecting film 2 is preferably corrosion resistant polyimide film (being the PI film).
The liquid-injection equipment that provides for the utility model is by pasting corrosion resistant protecting film 2(such as PI film on liquid-injection equipment inner walls 1), thus reach corrosion resistant purpose.
Need to prove that described PI film is a kind of raw material of present lithium ion battery protective tapes, it is the characteristic of electrolyte resistance corrosion, and cheap.
On the specific implementation, described PI protecting film not only can stick on the liquid-injection equipment housing, can also stick on the transducer of liquid-injection equipment.Because the PI protecting film is a clear films, therefore do not influence the inner case that the battery production workman observes liquid-injection equipment, simultaneously, by on the liquid-injection equipment housing, pasting the PI protecting film, allow the battery production workman clean the dirty of liquid-injection equipment surface easily, can effectively prevent the corrosion of electrolyte liquid-injection equipment.
Therefore, the utility model can be kept under the constant situation of structure at existing liquid-injection equipment, by using the mode of PI protecting film, need not to increase too much cost, just can arrive to allow the corrosion resistant effect of battery liquid-filling equipment.Simultaneously, the utility model can guarantee the transparency of liquid-injection equipment, helps observing the inner case of liquid-injection equipment.In addition, maintainability of the present utility model is strong, changes the better protecting film of battery production workman.
In sum, compared with prior art, the corrosion-resistant liquid-injection equipment of a kind of lithium ion battery that the utility model provides, its liquid-injection equipment that can prevent lithium ion battery is corroded by electrolyte in the fluid injection process, guarantee the useful life of liquid-injection equipment, needed liquid-injection equipment production cost is low simultaneously, thereby reduced the production cost of lithium ion battery greatly, the widespread production that helps lithium ion battery is popularized, effectively improved the market competitiveness of lithium ion battery, be of great practical significance.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
