1. Overview: A Next-Generation Adsorbent for Modern DLE
As DLE projects move rapidly from pilot lines to commercial deployment, the industry increasingly favors adsorbents that can perform under harsh brine conditions.
G-300, our third-generation
spherical titanium-based lithium adsorbent, was created to meet these demands. It builds on the proven foundation of G-100 and G-200 while introducing major improvements in strength, flow behavior, and long-cycle durability.
Moreover, the material has already completed over one quarter of stable mass production. Multiple global DLE developers are now running small-scale and mid-scale pilot evaluation
s, confirming both its consistency and its industrial readiness.
2. Key Technical Advantages
2.1 Higher lithium capacity
G-300 delivers an operational adsorption capacity of ≥ 6.0 mg/g and a saturation capacity of ≥ 14.0 mg/g, enabling shorter cycles and greater throughput.
Furthermore, the optimized structure supports faster mass-transfer kinetics.
2.2 Strong mechanical robustness
Thanks to its reinforced spherical architecture, G-300 achieves an attrition retention rate ≥ 95% (RBM test). This makes the material particularly suitable for systems with continuous circulation or high shear forces.
2.3 Improved flow dynamics
Unlike rod-shaped adsorbents, the spherical form significantly reduces channeling and pressure drop. As a result, operators experience smoother flow even when handling high-viscosity sulfate brines or concentrated mother liquor.
2.4 Lower bulk density for higher bed height
With a bulk density of 0.40–0.50 g/mL, G-300 provides more volume per ton of product. Consequently, the same column footprint can process more brine per cycle.
2.5 Minimal dissolution loss
A single-cycle dissolution rate of ≤ 0.005% ensures clean operation and stable long-term performance.
3. Broad Brine Compatibility
G-300 supports nearly all brine chemistries used in DLE.
For instance, it performs effectively in:
-
carbonate alkaline brines
-
sulfate brines
-
chloride brines
-
high Mg/Li ratio resources
-
geothermal brines
-
oilfield water containing lithium
-
lithium sink mother liquor
-
battery-recycling leachate
This wide adaptability stems from its strong lithium selectivity and its resistance to interference from Mg²⁺, Ca²⁺, Na⁺, K⁺, and boron.
4. Process Compatibility
G-300 integrates smoothly into multiple DLE system architectures.
In addition to traditional fixed-bed columns, it also supports:
-
moving-bed and expanded-bed processes
-
continuous adsorption–desorption loops
-
multi-column cascades
-
skid-mounted modular DLE units
Because of its spherical morphology, the material offers better mechanical stability in moving-bed systems compared with second-generation rod-shaped adsorbents.
5. Regeneration and Operating Requirements
According to its technical specifications, adsorption becomes effective when pH ≥ 5, and maintaining the pH above this threshold ensures stable lithium uptake. During desorption, HCl or H₂SO₄ delivers a clean and efficient regeneration cycle, producing eluate typically around 3–5 g/L Li⁺.
In addition, the material can be regenerated repeatedly with minimal loss in capacity.
6. G-300 vs. G-200: What’s New?
Although G-200 remains widely adopted across DLE pilots, G-300 provides several strategic upgrades:
| Feature | G-200 | G-300 |
|---|---|---|
| Morphology | Rod-shaped | Spherical |
| Mechanical strength | ≥ 90% RBM | ≥ 95% RBM |
| Density | 0.45–0.65 g/mL | 0.40–0.50 g/mL |
| Flow resistance | Medium | Low |
| Process suitability | Fixed-bed | Fixed-bed + moving-bed |
| Cycle life | Long | Longer, more stable |
In summary, the G-300 platform delivers higher durability, better flow behavior, and more flexibility for plants transitioning from pilot to commercial operations.
7. Why Developers Choose G-300
Consequently, the material is becoming a preferred option for new DLE projects.
Developers highlight several advantages:
-
reliable commercial-scale production
-
consistent quality and uniform spherical geometry
-
excellent resilience under harsh brine conditions
-
strong cost-performance ratio
-
suitability for long-cycle continuous operation
Therefore, G-300 is not merely a laboratory-grade upgrade — it is a fully industrialized adsorbent ready for real-world deployment.
8. Conclusion
As the global lithium industry shifts toward rapid DLE commercialization, adsorbents must combine strength, capacity, and stability. G-300 meets these demands with a next-generation spherical design and proven industrial performance.
For companies looking to accelerate pilot validation or scale toward commercial throughput, G-300 provides a robust, future-ready solution.
