Actionable insights from planning to execution
Three cost-saving paths:
● 40% lower low-humidity environment cost
● No solvent recovery system
● Corrosion-resistant materials replace precious metals. Total CAPEX is 15–25% lower than equivalent lithium-ion lines.
TOBGROUP’s triple protection:
● Super-wetting electrolyte infusion
● Gradient pressure formation protocol
● Real-time ultrasonic monitoring. Short-circuit rate controlled to ≤0.2ppm.
Three built-in interfaces:
● Switchable Al/stainsteel cathode current collectors
● Coater compatible with high-pH slurries
● Calender pressure range covers hard/soft carbon compaction needs.
Vertical layout:
● Electrode assembly + vertical flow
● AGV cluster logistics. Only 8,000㎡ (including dry room), 30% smaller than lithium-ion lines.
TOBGROUP delivered a 3000F 60138 supercapacitor pilot line with full equipment, materials, and on-site commissioning support.
TOBGROUP designed a Na-ion battery lab line producing 18650S, 32138S, 32140S cells for advanced research and development.
