Battery Equipment
The Targray Battery Division is focused on providing advanced materials and supply chain solutions for lithium-ion battery manufacturers worldwide. We also advise cell manufacturers on their R&D and pilot line equipment purchases, helping identify the best tools and production processes for our materials.
About our Battery Equipment Solutions
From initial concept to after-sales service including on-site support via design, manufacturing and installation, we help guide you through the necessary planning steps to ensure that your manufacturing process will meet your organization’s exact needs.
Whether you are seeking battery equipment to replace an aging production line, or simply want to substitute a single piece of machinery, our battery engineers and advanced material experts lend their full support to help you achieve your project goals.
Notching Mold
Notching dies are precision tools used in secondary battery assembly equipment to notch electrodes accurately and consistently.
| Category | Remark |
| Electrode size | 6 ~ 12um (can be customized according to customer specifications) |
| Electrode thickness | 100 ~ 190um (can be customized according to customer specifications) |
| Integral mold | Electrode Min-Max Size : Width(80 ~ 400m), Height(100 ~ 300mm) |
| Modular mold | Electrode Min-Max Size : Width(80 ~ 400m), Height(150 ~ 600mm) |
| Quality |
Total circumference burr under 7~10㎛ Active material parts delamination under 200㎛ |
| Warranty |
Single-run output: 600k–800k anode/cathode (varies with punch oil use in mass production) No warranty if not mold-related – e.g., press flatness, tape contamination, or adhesion issues |
| Regrinding |
Anode/cathode 600k–800k hits per use, followed by inspection and regrinding (up to 20 regrinds) Mold can be reused after punch and die replacement once 20 regrinds per mold are reached Mold overhaul required after two reuse cycles following punch/die replacement |
| Customizable mold per production | 1 Cavity ~4 Cavity (Mold size changes required per cavity configuration) |

Stand-alone Notching Machine
The stand-alone notching machine is used to notch the uncoated area of electrodes after slitting (pre-stacking process).
Stand-alone Stacking Machine
Once the notching process is complete, the stacking machine stacks a specified number of anodes and cathodes.
