| Product type | Typical thickness range | Width range | Core advantage |
| Pure lithium metal strip | 20 - 80 $\mu m$ | Customization | Ultra-thin manufacturing process. The common lithium strips on the market are usually around 100 microns thick. We offer ultra-thin lithium strips as low as 20 microns, which enhances the battery's energy density and reduces dead lithium. |
| Copper-lithium composite strip | 40 - 100 $\mu m$ | Customization | High-strength composite. The lithium layer is perfectly combined with ultra-thin copper foil, significantly enhancing the material's mechanical strength, enabling it to better adapt to the tension of automated winding equipment and providing a better current collection effect. |
