LANHE(LAND) CT3002A: The Precision Instrument Behind the 13-Second Battery Charge

High-Entropy Sulfoselenide Redefining Sodium-Ion Battery Limits

A major study, published in Nature Communications in April 2025, introduces a breakthrough: the HESSe electrode (Cu_0.88 Sn_0.02 Sb_0.02 Bi_0.02 Mn_0.02 S_0.9 Se_0.1) While sodium-ion batteries (SIBs) offer significant cost and safety advantages, their widespread adoption has been hindered by kinetic limitations and large volume expansion in conventional conversion electrodes.

By leveraging high-entropy doping and a “nanoflower” hierarchical morphology, this HESSe material enables record-breaking ion diffusion kinetics. Researchers achieved a reversible capacity of 365.7 mAh/g in just 13 seconds under a massive current density of 100 A/g.

The High-Precision Tool: LANHE CT3002A

Validating such extreme performance requires elite equipment. The study relied on the LANHE CT3002A testing system. In research where currents are massive and reactions are near-instantaneous, high precision is a scientific necessity to ensure data integrity.

Why the LANHE CT3002A is the industry standard:

• Exceptional Measurement Accuracy: Featuring 0.05% Full Scale (FS) accuracy for both voltage and current, LANHE ensures total reliability even during ultra-fast charging protocols.
• Long-Term Stability Monitoring: The device successfully tracked the electrode’s stability over 10,000 cycles. For absolute rigor, capacity retention was calculated using the 3rd (activated) cycle as a reference point, eliminating initial instabilities.
• “Four-Electrode” Technology: The system utilizes a four-wire (Kelvin) connection that physically separates the power and measurement circuits. This configuration is vital for eliminating parasitic voltage drops in cables, allowing the LANHE system to measure the true potential of the electrode with 0.05% accuracy even at very high currents.
• Advanced Kinetic Analysis (GITT): LANHE precisely measured sodium diffusion coefficients () via the Galvanostatic Intermittent Titration Technique (GITT), proving that the high-entropy structure effectively reduces energy barriers for ion transport.
