Unlike traditional cylindrical or prismatic batteries, a pouch battery cell uses a flexible, heat-sealable aluminum laminate casing instead of a rigid metal shell. It is thinner, lighter, and more adaptable in shape.<\/p>\n<p>By these natures, the compound annual growth rate (CAGR) of the pouch battery cells is higher than the that of prismatic and <a href=\"https:\/\/www.leadintelligent.com\/en\/cylindrical-batteries-market-size-types-and-trends\/\">cylindrical battery cells market<\/a>, which would reach around 17.5% in 2030, compared with the CAGR of the cylindrical cells of 7.5 &#8211; 9%, and the prismatic cells of 14.1% in the same period.<\/p>\n<p>With pouch battery cells expanding nearly twice as fast as cylindrical ones, it&#8217;s clear why they deserve attention. This guide will help you understand everything you need to know about pouch battery cells, from how they work and where they&#8217;re used to their benefits and challenges.<\/p>\n<p><img
