Solving Silicon-Anode Welding Challenges with Precision Electrodes
Industry Challenge:
2025 EV batteries require welding 120μm silicon composite foils without micro-cracks – a task where 78% manufacturers report >6% scrap rates (NAATBatt 2024 survey).
Our Solution:
Topower’s TP-8000 system integrates:
-
Diamond-Coated Electrodes
- 0.005Ω contact resistance (vs. 0.02Ω industry standard)
- 2,000-hour lifespan with auto-rotation maintenance
-
Real-Time Material Analysis
Our on-site lab data shows:
| Material | Traditional Pitting Depth | TP-8000 Result |
|---|---|---|
| Si-C Composite | 12.3μm | 1.8μm |
| Li-metal Foil | Partial melt-through | 0 defect |

Adaptive Pulse Control for Multi-Layer Stacking
Production Reality:
CATL’s 2025 cell design requires welding 8-layer nickel tabs within 0.3mm tolerance.
TP-8000 Innovation:
Our SmartWave™ Technology achieves:
- 256-level pulse adjustment (vs. standard 8-level)
- <0.5% energy deviation across 10,000 welds
- Case Study: Dongfeng Motor increased stacking speed by 40% while reducing thermal stress
Technical Breakdown:
| Pulse | Phase Function | Benefit |
| Pre-heating | Gradual temperature ramp | Prevents foil delamination |
| Core Energy | Dynamic impedance matching | Eliminates splash (99.8% clean rate) |
| Post-flow | Controlled cooling | Reduces intermetallic compounds |
Zero-Defect Production Through AI Vision
Critical Need:
Hidden weld defects cost automakers $28,000/hour in delayed deliveries (ABI Research 2024).
Our System Features:
-
3D Laser Profilometry
- 0.8μm resolution defect detection
- 100% inline inspection at 1.2 welds/sec
-
Machine Learning Database
