The Ultimate Frontier

Producing the Cell Itself

This is the pinnacle of technology transfer—moving beyond assembly to master the core science. Tradebone enables you to establish a complete lithium-ion (LiFePO4) or sodium-ion cell manufacturing plant. We transfer the entire know-how, from raw material mixing to the formation of a finished, graded cell, making you truly independent in the energy storage supply chain.

The Complete Production Process We Transfer

Our plant covers every critical stage in a controlled, clean-room environment:

1. Electrode Manufacturing:

  • Slurry Mixing:
    Precise mixing of active material (LFP or Sodium compounds), conductive agents, and binders.
  • Coating & Drying:
    Uniform coating of slurry onto aluminum (cathode) and copper (anode) foils in a Class 6 Cleanroom.
  • Rolling (Calendering):
    Compressing the coated electrodes to exact density and thickness for optimal energy density.
  • Slitting & Notching:
    Cutting electrodes to the required cell size.

2. Cell Assembly (In Class 7 Cleanroom):

  • Stacking/Winding:
    Creating the cell core (jelly roll) by layering anode, separator, and cathode.
  • Tab Welding:
    Ultrasonic welding of tabs to the electrode layers.
  • Encasing:
    Sealing the jelly roll in a prismatic aluminum case or pouch.
  • Electrolyte Filling:
    Precise injection of electrolyte in a dry-room

3. Formation, Aging & Testing (The "Activation"):

  • Formation:
    The first charge/discharge cycle that forms the critical SEI layer—the heart of cell longevity and safety.
  • Aging:
    Stabilizing the cell chemistry.
  • Grading & Capacity Sorting:
    Testing each cell's actual capacity, internal resistance, and self-discharge rate to sort into performance batches (Grade A, B, etc.).
  • Hi-Pot Testing:
    Ensuring insulation and safety integrity.

Production Capacities & Cleanroom Standards:

  • Plant Scale:
    We design plants with annual output ranging from 100 MWh to 1 GWh+, scalable in phases.
  • Cell Formats:
    Prismatic and pouch cell production lines.
  • Cell Capacities:
    Compressing the coated electrodes to exact density and thickness for optimal energy density.The line can be configured to produce the full spectrum of cells, from 50Ah to 320Ah, by adjusting electrode dimensions and stacking patterns.
  • "0" Pollution Workshop:
    We implement closed-loop systems for solvent recovery and waste treatment, ensuring environmental compliance.
  • Key Technology:
    We emphasize the 8-stage formation and aging process and 6-point Hi-Pot testing that guarantees the safety and cycle life promised by the cell chemistry.
