Lithium-Copper Composite Strip Specifications
Composite Services
- We can produce according to customer requirements: single-sided composite, double-sided composite, multilayer composite strip.
2. Composite strip thickness: lithium layer thickness (1μm–80μm) × composite width (≤350mm), including lithium alloy-streamlined composite strip products.
3. According to customer requests, substrates can be replaced with pure copper foil, micro-porous nickel foil, etched foil, punched foil, micro-etched foil, stainless steel foil, etc.; customers may also provide base materials for processing into lithium/alloy-streamlined composite strips.
4. Lithium can be alloyed, and we can also develop bimetallic and trimetallic alloy-streamlined composite strips according to customer requirements.
