WinCore\u00ae winding cores for demanding winding processes in battery production<\/h2>\n\n\n\n

In battery and fuel cell production, cleanrooms and dry rooms impose particularly stringent demands on the materials and production equipment utilized. Moisture, dust, or impurities can cause lasting damage to the sensitive electrode tracks and metallic foils, thereby impairing the performance and lifespan of the energy storage devices. Furthermore, the winding process necessitates precise and consistent material guidance to prevent tension loss, wrinkling, or material distortion.
The innovative WinCore\u00ae winding cores from INOMETA are specifically engineered to address these challenges. They guarantee dust-free and abrasion-free operation, maintain permanent dimensional stability even under fluctuating temperature and humidity conditions, and thus ensure a smooth, low-tension web run. Consequently, they assure a high level of process reliability, reduce rejects, and help to significantly minimize downtime in one of the most demanding production areas of the energy storage industry.<\/p>\n\n\n\n

Why INOMETA relies on aluminium, CFRP and GRP for winding cores<\/h2>\n\n\n\n

For WinCore\u00ae winding cores<\/a>, INOMETA employs state-of-the-art high-performance materials such as aluminium, CFRP, and GRP, carefully selected according to specific requirements concerning weight, rigidity, and temperature resistance. Aluminium exhibits particular excellence due to its outstanding thermal stability, whereas CFRP and GRP offer compelling benefits with their low weight and high strength. This material diversity enables optimal adaptation to various production processes and contributes significantly to durability, sustainability, and process reliability. In comparison to conventional cardboard cores, WinCore\u00ae winding cores provide decisive advantages. They demonstrate significantly greater resistance to mechanical and thermal stresses, do not generate dust or abrasion, and maintain their dimensional integrity even under extreme conditions. Consequently, they sustainably reduce waste and resource consumption and are successfully implemented in key production stages within battery and fuel cell manufacturing, including substrate production, electrode production, coating, drying, slitting, cell assembly, and further processing.<\/p>\n\n\t<\/div>\n\n<\/div>\n\n\n

Winding cores in substrate & electrode production<\/h3>\n\n\n\n

WinCore\u00ae winding cores are indispensable in the early production phases of battery and fuel cell manufacturing. They function as precise carriers for sensitive metallic foils, such as copper, separator- or aluminium, which serve as current collectors in battery cells. Their high concentricity ensures tension-free and crease-free winding of these foils, effectively preventing mechanical stress and material deformation. This gentle handling is essential for the functionality and reliability of the subsequent cells. With WinCore\u00ae winding cores, manufacturers benefit from improved material quality and enhanced process stability throughout the substrate and electrode production value chain.<\/p>\n\n\t<\/div>\n\n<\/div>\n\n\n
