Descripción general

Detalles

This product is a conventional artificial graphite anode material developed for lithium-ion battery research and experimental applications. With a D50 particle size of approximately 15.6 μm and a BET specific surface area around 1.4 m²/g, it offers a balance of high tap density (1.21 g/cm³) and low ash content (0.01%), supporting consistent electrode preparation. The material delivers an initial reversible capacity of ≥330 mAh/g and an initial Coulombic efficiency of ≥92%, enabling long cycle life and reliable performance under both high and low temperature conditions. Its optimized particle size distribution (D10: ~7.7 μm, D90: ~29.2 μm) facilitates stable slurry processing. Recommended for use with graphite coin cell electrolyte (KLD-1230C) and controlled compaction—double-sided at 1.55 g/cm³ or single-sided below 1.2 g/cm³ to avoid curling—this material is well suited for evaluating anode performance in energy storage research.

Long cycle life.
Good high and low-temperature performance.
Excellent comprehensive performance.
