TOBGROUP offers complete, turnkey prismatic cell lab line and pilot line. Engineer high-performance prismatic cell with a lab line built for your specific goals. From facility design and equipment supply to installation and staff training, we provide an integrated solution.
TOB NEW ENERGY solves the problems with prismatic cell technology R&D by providing a full-stack small-scale prismatic cell lab line solution. It is made for checking materials, developing processes, and making prototypes for trial production. It includes advanced systems like sodium-ion batteries and liquid/solid-state lithium batteries, which help customers achieve:
● Efficient formula iteration: You can compare multiple parameters in one day.
● Low-cost trial and error: Smaller equipment means less money spent on research and development.
● Preview of mass production: Process data flows smoothly into the pilot stage.
Core Capabilities:
(1) Compact output: 50–300 cells per day (suitable for 18650/21700/26650 and unique prismatic requirements).
(2) Full-system compatibility: high-nickel cathodes, silicon-based anodes, liquid and solid-state electrolytes, and other delicate materials.
(3) Important process coverage:
▶ Dispersion of nanoscale slurry → Ultra-thin coating (5-150 μm) → Accurate rolling (density control ±0.05g/cm³).
▶ Laser tab cutting → Z-stacking and fully automatic winding → Case laser welding (leak rate ≤10⁻¹¹ Pa·m³/s).
▶ Solid-state electrolyte pressing → Micro-injection (accuracy ±0.5%) → Shape and formation (closed-loop pressure control).

● Flexible research and development platform
(1) Modular equipment architecture: Each unit (slurry mixing, coating, and assembly) can work on its own, allowing for standalone experiment or full-line integration.
(2) System for quick changes: The time it takes to change the size of the case or the width of the electrode is less than 15 minutes. The time it takes to change the formula of the electrode is less than 30 minutes.
(3) Process boundary exploration: A wide range of adjustments to parameters like calendering pressure (1–100T) and coating speed (0.5–5m/min).
● Reliability of Production-Level Data
(1) Closed-loop process parameter control: Monitoring online areal density (with an accuracy of ±0.5%) and using AI to check for defects in electrodes.
(2) Full traceability of data: An integrated LIMS system that links material batches, process parameters, and electrochemical performance data (cycle life, DCIR, and rate capability).
(3) Interface for failure analysis: Pre-equipped electrode sampling ports and in-situ gas production detection to speed up research into how things fail.
● Advanced Technology Pre-Research Capability
(1) Solid-state battery adaptation: Dry electrode forming module, solid-state electrolyte thin-film hot-pressing unit (optional).
(2) High-voltage system support: Filling system resistant to corrosion environments above 4.5V, specialized coating head for ceramic-coated separators.
(3) Ultra-fast charging validation: Supports 5C+ formation process, integrated test channels with liquid-cooled fixtures.
● Matching at Deep Needs:
Technical route analysis, experimental objective decomposition, and equipment selection matrix development are performed to match R&D requirements accurately.
● Delivery of the line on Agile basis:
Equipment installation, process debugging, and SOP output for readiness towards production shall be managed within a 30-day rapid deployment to make production ready.
● Empowerment Technically:
Training of personnel, monthly optimization report, and mass production transition consulting shall deliver continuous innovation and scalable manufacturing.
Core enablers of technological implementation
Actionable insights from planning to execution
● Pre-equipped with advanced interfaces: The dry electrode module is powder direct coating + hot pressing (no solvent interference).
● Lithium metal anode adaptation: Assembly in inert atmosphere protection, interface pressing unit.
● Solid state battery specialization: Electrolyte powder tablet press, multi layer stacking hot press.
TOBGROUP shares a three-step strategy
● Prismatic cell lab line locks basic process windows → Pilot line verifies equipment compatibility → Mass production line parameter package import.
● Equipment upgrade path- Coater web width expansion (150→650mm), stacking speed upgrade (0.3s→0.15s/piece).
