Complete advanced sodium-ion battery lab line solutions from TOBGROUP. Get tailored lab design, equipment supply, and technical support for your research needs.
TOBGROUP offers an end-to-end sodium-ion battery lab line solution designed to overcome the technical challenges of sodium-ion batteries. Focused on material screening, formula optimization, process validation, and small-batch sample preparation, it supports three major technical routes: layered oxides, polyanionic compounds, and Prussian blue analogues. This solution helps customers achieve an efficient closed loop from “formula design” to “performance verification”.
The lab is built on a design philosophy of “research-grade precision + engineering thinking”, ensuring data accuracy while incorporating scale-up interfaces to lay a solid foundation for subsequent pilot-line conversion.
Core Positioning:
● Material Innovation Platform: Supports rapid validation of cathodes (e.g., NaCrO₂, NaFePO₄), anodes (hard carbon, soft carbon, titanium-based), and electrolytes (ester/ether-based).
● Process Exploration Hub: Covers the entire process from electrode preparation to cell assembly and formation aging, compatible with liquid/semi-solid systems.
● Data-Driven R&D: Integrates high-precision testing and intelligent analysis systems to achieve multi-dimensional correlation among performance, process, and materials.
● Seamless Pilot-Scale Transition: Equipment parameters align with mass production logic, and validation data can directly support industrial-scale decision-making.

TOBGROUP Sodium-ion Battery Lab Line: Bridging R&D from Atomic-Level Design to Cell-Level Validation
● Full-Stack Sodium-ion Battery R&D Capability Coverage
(1) Material Level: Provides a dedicated material library for sodium-ion batteries (precursors, binders, conductive agents, electrolytes) and custom synthesis services.
(2) Equipment Level: Modular small-scale equipment (coating width: 100–300 mm, compaction pressure: 0–100 T) supports ultra-wide parameter window debugging.
(3) Data Level: LIMS (Sodium-ion Battery Lab Line Information Management System) automatically correlates process parameters with electrochemical data (cycling, DCIR, dQ/dV).
● Exclusive Process Adaptability for Sodium-ion Battery
(1) Low Humidity Control: Electrode preparation area dew point ≤ -40°C (stricter than lithium battery standards), suppressing sodium activity decay.
(2) Corrosion-Resistant Design: Equipment contact parts made of stainless steel 316L/ceramic coating to resist corrosion from sodium salt electrolytes.
(3) Low-Pressure Formation Technology: Custom formation protocols (e.g., 0.05C pre-sodiation) improve first-cycle efficiency and cycling stability.
● Intelligent Research Platform
(1) In-Situ Detection Integration: Optional in-situ XRD/SEM sample chambers for real-time observation of sodium dendrite/phase transition behavior.
(2) AI Parameter Optimization: Predicts optimal formula ratios based on sodium-ion battery lab line historical data (e.g., effect of binder content on hard carbon anodes).
(3) Safety Warning System (Early Warning System): Multi-channel thermal runaway monitoring (temperature + gas + deformation) ensures safety during experiments with highly active materials.

Core enablers of technological implementation
Actionable insights from planning to execution
● Material properties: stricter humidity control required (sodium is more hydrophilic), corrosion-resistant equipment design (sodium salt electrolytes are more corrosive).
● Process differences: focus on solving sodium-specific issues like low first-cycle efficiency of hard carbon anodes, high compaction rebound, and sodium dendrite suppression.
Fully compatible: equipment parameters cover the diverse needs of layered oxides (high compaction), polyanionic compounds (high voltage), and Prussian blue (aqueous slurry). Quick switching via module replacement.
Data homology principle: laboratory equipment control logic (e.g., coating shear rate, roller line pressure) is consistent with the pilot line. Parameter mapping model: LIMS establishes a correlation matrix between lab and pilot key parameters to reduce scaling deviations.
Material library + custom services: supplies mainstream sodium battery materials (e.g., biomass hard carbon, Na₃V₂(PO₄)₃) and collaborates with partners to develop new materials (e.g., O3/P2 phase composite cathodes).
Scalability reserved interfaces: equipment layout allows for space reservation; key units (coating/rolling/testing) can be directly replaced with pilot-scale models, reducing upgrade costs by over 40%.
Core requirements: independent power supply (≥50 kW), compressed air (0.7 MPa), cooling water (5°C). Environment: electrode area (-40°C dew point), assembly area (class 10K cleanliness + inert atmosphere), dedicated waste electrolyte recycling system.
