Description

Overview

Key Features

1. High-Performance SIB Material System
   • Cathode (NVP: Na₃V₂(PO₄)₃): Boasts high sodium-ion conductivity (~10⁻⁴ S/cm) and exceptional structural stability (no phase transition during cycling), with a flat voltage plateau (~3.4 V vs. Na⁺/Na) that facilitates capacity and voltage performance analysis.
   • Anode (Hard Carbon): Features an optimized porous structure suitable for sodium-ion intercalation, offering high reversible capacity and low first-cycle irreversible capacity loss (<15% at 0.1C) – a critical attribute for accurately evaluating active sodium retention.
2. Dry-Process Enhances Research Reliability
   • Solvent-free electrode manufacturing controls residual moisture below 30 ppm and avoids solvent-induced electrode cracking, ensuring uniform ion transport and stable interface formation across all cells.
   • Compared to wet-process cells, the dry process improves electrode density and adhesion, reducing capacity fading caused by electrode delamination during long-cycle testing.
3. Research-Optimized Capacity & Consistency
   • Nominal capacity of 1Ah: Balances “sufficient energy for meaningful testing” and “small-scale flexibility” (ideal for scenarios with limited electrolyte volume or in-situ characterization requirements).
   • Batch-to-batch consistency <3% (tested at 0.1C, 25°C): Ensures reliable comparability of results across different experiments (e.g., electrolyte formulation screening, cycling protocol optimization).

Technical Support

• Provision of detailed cell assembly drawings and Material Safety Data Sheets (MSDS) to meet compliance and operational needs;
• Customization of formation protocols based on specific research goals (e.g., high-rate testing, low-temperature cycling, SEI film optimization);
• Collaborative troubleshooting support for abnormal performance trends (e.g., excessive gassing, rapid capacity fading, voltage plateau shifts).
