+| **Pure Copper** | High-performance (30A+) | Lowest resistance; minimal heat generation. | Extremely difficult to spot weld (requires laser/ultrasonic). |
22
+| **Sandwich** | High-current DIY (Nickel + Copper) | Better conductivity than pure nickel; weldable with high-power spot welders. | Hard to tune welding parameters; risk of "cold" welds or blow-through. |

+### Why we choose Pure Nickel for 18650s:
43
+1. **High Resistance (Ideal for Welding):** Spot welding relies on electrical resistance to generate heat. Nickel resists current just enough to melt instantly at the contact point, creating a strong bond.
44
+2. **Thermal Control:** Copper is a "heat sink"—it pulls heat away so fast that the weld point never gets hot enough to melt, but the battery cell underneath gets dangerously hot.
45
+3. **Corrosion Resistance:** Nickel does not rust or oxidize easily. Copper turns green (oxidizes) over time, which increases resistance and creates "hot spots."
46
+4. **Tool Compatibility:** Most hobbyist spot welders (Sunkko, Malectrics, Kweld) are designed specifically for the physics of nickel.

+### 2. Al-Ni (Aluminum-Nickel) Composite Strips
52
+
53
+**Primary Purpose:** Transitioning between dissimilar metals.
54
+
55
+* **When to use:** Specifically for **Pouch Cells** or **Prismatic Cells** where the positive terminal (tab) is made of **Aluminum**.
56
+* **Why:** Aluminum and Nickel do not bond well through standard spot welding.
57
+* **How it works:** The strip is bi-metallic (half Al, half Ni).
58
+ * **Al side** is welded to the battery's Aluminum tab.
59
+ * **Ni side** provides a weldable surface for standard nickel busbars or wires.
60
+* **Summary:** It is a "bridge" material, not for 18650s (which use steel/nickel caps), but for batteries with raw aluminum electrodes.
