Introduction<\/h2>\n\n\n\n<p>With the continuous progress of science and technology, lithium battery plays an increasingly important role in our daily life and work. As a key link in the manufacturing process of lithium batteries, the coating process is pivotal to ensuring the performance and safety of lithium batteries. However, in the actual production process, the problem of slight cracks in the coating of lithium batteries often occurs, which not only affects the aesthetics of lithium batteries, but more importantly, may have a negative impact on their performance and safety. Therefore, the purpose of this paper is to discuss the causes and response strategies of minor cracks in lithium battery coatings, in order to provide useful references for relevant enterprises and researchers.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"434\" height=\"226\" src=\"https:\/\/www.hyybattery.net\/wp-content\/uploads\/2024\/03\/image-1.png\" alt=\"image 1\" class=\"wp-image-4850\" style=\"aspect-ratio:1.7777777777777777;object-fit:cover;width:910px;height:auto\"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Second, lithium battery coated light fine cracks cause analysis<\/h2>\n\n\n\n<h4 class=\"wp-block-heading\">Problems with coating materials<\/h4>\n\n\n\n<p>Coating material is one of the key factors affecting coating quality. If the composition of the coating material is not stable, the viscosity is not moderate or the solid content is not up to standard, etc., it may lead to cracks when coating. In addition, insufficient adhesion between the coating material and the substrate is also an important reason for the appearance of cracks.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Adjustment of coating process parameters<\/h4>\n\n\n\n<p>Adjustment of coating process parameters is crucial for the control of coating quality. For example, improper adjustment of coating speed, temperature, humidity and other parameters may lead to cracks in the coating. In addition, the matching degree of each process parameter in the coating process is also an important factor affecting the coating quality.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Problems with equipment<\/h4>\n\n\n\n<p>Problems with the coating equipment may also lead to the appearance of coating cracks. For example, improper control of parameters such as the surface roughness of the coating rollers and the pressure between the coating rollers and the substrate may affect the coating quality. In addition, improper maintenance of equipment or aging of equipment may also lead to the appearance of coating cracks.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Environmental factors<\/h4>\n\n\n\n<p>Environmental factors may also affect the coating quality, such as the environment of the temperature, humidity and other parameters are not properly controlled, may also lead to cracks in the coating. In addition, environmental contaminants such as dust and impurities may also have a negative impact on coating quality.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;uploadedSrc&quot;:&quot;https:\\\/\\\/www.hyybattery.net\\\/wp-content\\\/uploads\\\/2024\\\/03\\\/image.png&quot;,&quot;figureClassNames&quot;:&quot;wp-block-image size-full is-resized&quot;,&quot;figureStyles&quot;:null,&quot;imgClassNames&quot;:&quot;wp-image-4848&quot;,&quot;imgStyles&quot;:&quot;aspect-ratio:1.7777777777777777;object-fit:cover;width:890px;height:auto&quot;,&quot;targetWidth&quot;:1080,&quot;targetHeight&quot;:743,&quot;scaleAttr&quot;:&quot;cover&quot;,&quot;ariaLabel&quot;:&quot;\\u653e\\u5927\\u56fe\\u7247\\uff1aimage&quot;,&quot;alt&quot;:&quot;image&quot;}\" data-wp-interactive=\"core\/image\" class=\"wp-block-image size-full is-resized wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"1080\" height=\"743\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on-async--click=\"actions.showLightbox\" data-wp-on-async--load=\"callbacks.setButtonStyles\" data-wp-on-async-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/www.hyybattery.net\/wp-content\/uploads\/2024\/03\/image.png\" alt=\"image\" class=\"wp-image-4848\" style=\"aspect-ratio:1.7777777777777777;object-fit:cover;width:890px;height:auto\" srcset=\"https:\/\/www.hyybattery.net\/wp-content\/uploads\/2024\/03\/image.png 1080w, https:\/\/www.hyybattery.net\/wp-content\/uploads\/2024\/03\/image-768x528.png 768w\" sizes=\"(max-width: 1080px) 100vw, 1080px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"\u653e\u5927\u56fe\u7247\uff1aimage\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on-async--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"context.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"context.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>3.

At the same time, should strengthen the matching degree of adjustment between the process parameters, in order to improve the coating quality.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"3\">\n<li><strong>Ensure the good condition of equipment<\/strong><\/li>\n<\/ol>\n\n\n\n<p>Regular inspection and maintenance of coating equipment to ensure that the parameters of the equipment in a normal state, such as the surface roughness of the coating roller, the pressure between the coating roller and the substrate. For aging equipment should be replaced or upgraded in a timely manner to ensure the stability and reliability of the coating process.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"4\">\n<li><strong>Control of environmental factors<\/strong><\/li>\n<\/ol>\n\n\n\n<p>Reasonable control of environmental factors, such as environmental temperature, humidity, etc., to ensure the quality of coating. At the same time, the cleanliness of the workshop should be strengthened to reduce the dust, impurities and other pollutants on the coating quality.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"5\">\n<li><strong>Strengthen quality inspection<\/strong><\/li>\n<\/ol>\n\n\n\n<p>In the production process, strengthen the quality inspection to find and solve potential problems in time to prevent batch problems. Automatic testing equipment or artificial testing means can be used to monitor the coating quality of lithium batteries in real time, once found that the quality of minor cracks and other quality problems should be adjusted and repaired in a timely manner.<br>*** Translated with www.DeepL.com\/Translator (free version) ***<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>4. Conclusion<\/strong><\/h2>\n\n\n\n<p>Through the above analysis, it can be seen that the reasons for the slight cracks in the lithium battery coating are manifold, including coating materials, process parameters, equipment and environmental factors.
