Empower your battery research with a fully customized cylindrical cell lab line from TOBGROUP. We provide end-to-end services, from facility design and equipment supply to installation and staff training, ensuring your research transitions smoothly toward commercialization.
TOBGROUP offers a highly flexible cylindrical cell lab line for universities, research institutes, and corporate R&D centers. The cylindrical cell lab line supports mainstream models such as 18650/21700/26650/4680 and covers multiple technical routes, including liquid lithium batteries (LFP/NCM/high-nickel), sodium batteries, and solid-state batteries, enabling rapid iteration.
● Ultimate Modularity: Electrode preparation, winding assembly, electrolyte injection & sealing, and formation & testing units are independent and detachable, enabling in-depth optimization of individual processes.
● Micro-Process Capability: 0.5L mini slurry dispersion system, 100mm narrow-width coater (wet thickness accuracy ±1μm), and 0.01g-level micro-injection station.
● R&D Data Closed Loop: Integrated process parameter monitoring (viscosity/areal density/winding tension) and electrical performance testing (cycle/DCIR/rate), enabling "formula-process-performance" correlation analysis.

TOBGROUP Cylindrical Cell Lab Line: A Productive Engine from Idea to Sample
● R&D Platform:
(1) Electrode part lets fast changes of electrode size, coating area density, and pressing density.
(2) Winding section allows quick mandrel swaps (fits Φ10-80mm), with live tweak of layers/pull.
● Top-Class Pre-Study Skill:
(1) Works with dry electrode coating (straight powder coating), in-place solid-state electrolyte making, and pre-lithiation step check.
(2) Glove box under integrated inert atmosphere (O₂ ≤ 0.1ppm) for sodium battery/sodium system requirements.
● Low Cost & High Precision Assurance:
(1) Key sensor- thickness gauge, tension meter match pilot scale equipment, data ready for scaling.
(2) 60% lower equipment investment than a full Pilot Line, area ≤ 50㎡.
From concept to sample—TOB ensures full-cycle support:
● Technical Deep Interview: Be sure about the purpose of R&D (for example, cycle life enhancement for high-nickel systems or sodium battery interface optimization), sample specifications, and special process requirements.
● Customized Cylindrical Cell Lab Line Design: Offer module combination solutions (all-dry electrode unit or high-temperature injection system), equipment layout plan, and environmental planning.
● Accurate Equipment Supply: Supply core lab-level equipment (micro coater, adjustable winder, glove box integrated injection station)
● Process Debugging & Training: Parameter debugging shall be carried out by TOB engineers on-site, and 3 batches of samples shall be tried. Equipment operation, process adjustment, and data collection method training shall also be hands-on.
● Continuous Support: Remote process consulting, equipment maintenance guidance, material supply channels.
Core enablers of technological implementation
Actionable insights from planning to execution
Core modules (coater, winding machine) use the same technical platform as pilot-scale equipment so process parameters can be transferred directly. Equipment interfaces expansion space is reserved for easy upgrades to a pilot line.
● Basic configuration: Powder quantitative delivery system, hot press (pressure 0-100MPa), in-situ curing unit.
● Environment: Fully enclosed dry room (dew point ≤ -40°C).
● Data observation: Areal density gauge online (precision ±0.5mg/cm²).
Major steps (electrode making, assembling) should be done inside a glove box with an inert atmosphere (O₂ ≤ 1ppm, H₂O ≤ 10ppm). TOB gives full integrated glove box solutions.
