BTR M1-S2 Cathode Material 1kg

Name: BTR M1-S2 Cathode Material

Material Type: Lithium-Ion Battery Cathode Material

Product Code: M1-S2

Brand: BTR

Product Introduction:

The BTR M1-S2 is a lithium-ion battery cathode material supplied by BTR (Shenzhen). The material is characterized by D50 3.8 μm, tap density ≥ 2.0 g/cm³, specific surface area 0.5 m²/g, and low surface lithium residues, with half-cell capacity ≥ 180 mAh/g and ≥ 90% first-cycle efficiency in the 3.0–4.3 V window.

Key Features:

Particle size distribution — D10 2.5 ± 2.0 μm / D50 3.8 ± 2.0 μm / D90 7.0 ± 4.0 μm
High tap density ≥ 2.0 g/cm³ — supports high electrode loading and energy density
Specific surface area 0.5 ± 0.5 m²/g
Low surface lithium residues — OH⁻ ≤ 0.2 wt%, CO₃²⁻ ≤ 0.2 wt%
Low moisture content ≤ 600 ppm
Half-cell capacity ≥ 180 mAh/g at 0.1C, 3.0–4.3 V vs Li⁺/Li
First-cycle efficiency ≥ 90%

Physical & Chemical Properties:

Electrochemical Performance (Half-Cell, 0.1C/0.1C, 3.0–4.3 V vs Li⁺/Li):

Values measured by Xnergy. Typical values for reference; not guaranteed unless otherwise specified.

Packaging & Storage:

Store in a sealed container in a cool, dry environment away from heat sources, direct sunlight, acidic vapors, and reducing atmospheres. Once opened, reseal the inner moisture-barrier bag promptly. Prolonged exposure to ambient humidity can increase surface lithium residues and degrade electrochemical performance.

Safety:

For research and industrial use only. Wear appropriate PPE (chemical-resistant gloves, safety glasses, lab coat, dust mask or respirator) when handling M1-S2 powder, especially during weighing, transfer, and slurry preparation. Avoid generating dust; transfer powders in a fume hood or with local exhaust ventilation. Avoid contact with skin and eyes; in case of contact, flush with water and seek medical attention. Refer to the included Safety Data Sheet (SDS) for complete safety information.

Note: Specifications listed above are typical and for reference only. Actual electrochemical performance depends on the specific cell architecture, electrolyte formulation, binder/conductive-additive composition, coating thickness, calendering parameters, formation protocol, and testing conditions.
