Official Launch of TOP.E Digital Solid-State Battery 3D Printing Engineering Technology Center

On November 5, 2024, Panda3dp.com announced the official opening of the Solid-State Battery 3D Printing Engineering Technology Center, a collaborative project between TOP.E Digital (Xi'an) Technology Co., Ltd.（高能数造） and the National Graphene Innovation Center. This facility, now operational and open to the public, welcomed numerous battery experts, scholars, and engineers who visited for inspections, testing, and pilot productions.

The center houses cutting-edge production lines, including trial production lines for square aluminum shell power batteries, pouch and cylindrical batteries, solid-state battery 3D printing, and graphene-coated current collectors. Spanning an area of over 5,900 square meters, it has the capacity to test, analyze, develop, and produce small-scale samples of solid-state batteries, advanced energy storage cells, new power batteries, and 3C lithium batteries, as well as dry electrode technology. Production services are available for large square aluminum shell batteries (100Ah+), large cylindrical batteries with full-tab designs (32140/4680/4695), pouch cells (2-100Ah), and other solid-state batteries at pilot scale.

During the open house, visitors toured various sections of the engineering center. In the production area, they observed the high-efficiency manufacturing platform for all-solid-state battery composite electrodes and lithium metal anode equipment. These technologies enable precise preparation of double-sided electrolyte composite electrodes with advanced drying processes, automating composite electrode collection, lithium foil cutting, and pressing copper tab composite electrodes to form anodes. This walkthrough offered guests an insightful view into the manufacturing process for lithium-metal all-solid-state batteries.

In the on-site exchange session, the staff introduced the advantages and service capabilities of the center's solid-state battery 3D printing technology in the battery field.

Technological Advantages:

1. High Precision and Design Flexibility

   Enables the creation of micro-batteries and complex structured cells, such as ring and conformal batteries. 

2. High Energy Density

   Continuous microporous thick electrodes reduce the need for current collectors and separators, increasing energy density. 

3. High Power Density

   3D continuous microchannel electrodes offer broader ion diffusion channels, enhancing power density. 

4. Low Cost, Low Energy Consumption

   Thick electrodes reduce the need for current collectors and separators, minimizing solvent use. 

5. Multi-Material, Versatile Applications

   3D printing adapts to various battery materials, enabling production of novel cells such as flexible, solid-state lithium-ion, wearable, implantable medical, fuel, and perovskite thin-film batteries. 

6. Structural Battery Manufacturing

   Allows batteries to be integrated into product structures, making them part of the design.
