Overview

Specifications

Details

This Silicon-Carbon Alloy (1200) is designed for use as a lithium-ion battery anode material, with a surface carbon coating to enhance rate capability and cycling stability. Based on the provided specifications, the material exhibits a D50 particle size around 13 µm and a tap density of 0.89 g/cm³, supporting practical electrode processing. Electrochemical testing shows an initial reversible capacity of 1343.8 mAh/g and an initial Coulombic efficiency of 83.8%, indicating high capacity with reasonable first-cycle loss. For half-cell evaluation, it is recommended to use carbon-coated copper foil and NCM electrolyte (KLD-1230C), with electrode baking at 85 °C for 4 hours. The product should be stored under sealed conditions. This material is well-suited for energy materials research and anode development.

Storage Requirement: Materials must be stored in a sealed container.

Electrolyte Used for Testing: Si/C Electrolyte (KLD-Si01)

Recommended Current Collector: Carbon-Coated Copper Foil

Baking conditions for electrode: Bake at 85 ℃ for 4 hours

Lithium ion anode electrode material, surface coated with carbon, excellent rate performance, good cycling performance
