Clean<\/h2>\n\n\n\n

In battery cell manu\u00adfac\u00adturing, even the tiniest impu\u00adri\u00adties can deter\u00admine whether a cell is a reject or func\u00adtions prop\u00aderly. Micro\u00adscopic parti\u00adcles can damage sensi\u00adtive sepa\u00adra\u00adtors or trigger chem\u00adical reac\u00adtions. Mois\u00adture compro\u00admises mate\u00adrial stability. At the same time, processes involve ultra-thin foils and sensi\u00adtive coat\u00adings that are extremely suscep\u00adtible to envi\u00adron\u00admental influ\u00adences. The solu\u00adtion lies in consis\u00adtently controlled produc\u00adtion envi\u00adron\u00adments: clean\u00adrooms and dry rooms with minimal particle and mois\u00adture loads, combined with reli\u00adable, low-emis\u00adsion automa\u00adtion, provide the basis for consis\u00adtent quality and reli\u00adably func\u00adtioning cells. SCHUNK prod\u00aducts for battery cell manu\u00adfac\u00adturing feature high-quality anodized finishes and are certi\u00adfied for clean\u00adrooms and dry rooms. Special lubri\u00adcants are lithium-free and retain their prop\u00ader\u00adties even under extremely dry condi\u00adtions.<\/span><\/p>\n\n\n\n

Precise<\/h2>\n\n\n\n

Even the slightest devi\u00ada\u00adtions in posi\u00adtioning lead to elec\u00adtrical imbal\u00adances and mechan\u00adical stresses in cell manu\u00adfac\u00adturing, resulting in rejects. Toler\u00adances in the microm\u00adeter range are crit\u00adical when stacking anodes, cath\u00adodes, and sepa\u00adra\u00adtors, or when cutting extremely thin elec\u00adtrode foils. At the same time, deli\u00adcate mate\u00adrials are highly sensi\u00adtive to even the slightest forces or vibra\u00adtions. End-to-end preci\u00adsion is there\u00adfore essen\u00adtial: accu\u00adrate guid\u00adance and posi\u00adtioning, repro\u00adducible motion sequences, and contin\u00aduous moni\u00adtoring ensure the neces\u00adsary repeat accu\u00adracy along the entire process chain. SCHUNK grip\u00adpers, for example, are designed to move compo\u00adnents safely and posi\u00adtion them precisely in line with require\u00adments such as maximum surface pres\u00adsure or a defined grip\u00adping range.<\/span><\/p>\n\n\n\n

Quick<\/h2>\n\n\n\n

The growing demand for battery cells is increasing the pres\u00adsure on produc\u00adtion speed and costs. High produc\u00adtion volumes require extremely short cycle times \u2013 for example, when stacking, with each layer taking just a few tenths of a second. At the same time, speed must not come at the expense of quality, as errors have an imme\u00addiate economic impact.<\/p>\n\n\n\n

The key is the inter\u00adplay between speed and stability: highly dynamic, auto\u00admated processes, short setup times and down\u00adtimes, and end-to-end process control enable high output while main\u00adtaining consis\u00adtent quality. SCHUNK systems increase cycle speed through features such as parallel processing lines or extremely fast tool changes, for example in slit\u00adting.\u2002<\/span><\/p>\n\n\n\n

In slit\u00adting, the key is to achieve consis\u00adtently precise cut quality with high machine avail\u00adability. Even the slightest devi\u00ada\u00adtions have a direct impact on elec\u00adtrode quality. At the same time, knife changes must be performed quickly to mini\u00admize down\u00adtimes. Hydraulic expan\u00adsion tech\u00adnology enables low-vibra\u00adtion clamping of the cutting knives, ensuring stable processes, cleanly cut edges, and high effi\u00adciency during oper\u00ada\u00adtion.

In stacking, posi\u00adtioning accu\u00adracy and cycle time deter\u00admine the quality of the cell stacks. Even minimal misalign\u00adments can lead to defec\u00adtive layer struc\u00adtures and result in rejects. Elec\u00adtrode layers can be posi\u00adtioned precisely through care\u00adfully controlled move\u00adments and synchro\u00adnized sequences. Process steps conducted in parallel further increase speed and improve yield.

After stacking, deli\u00adcate cell stacks must be trans\u00adported reli\u00adably and with full process control. Even a slight misalign\u00adment of the layers will impair the cell\u2019s func\u00adtion. Stable mounting combined with gentle handling is there\u00adfore essen\u00adtial. Customized grip\u00adping and holding concepts reli\u00adably secure the stack, mini\u00admize mechan\u00adical stresses, and ensure consis\u00adtently high quality throughout the process chain.
