Detalhes

This product is a silicon-carbon composite anode material developed for high-energy-density lithium-ion batteries, featuring a porous carbon framework infiltrated with deposited silicon. It offers a reversible capacity exceeding 1800 mAh/g at 1.5 V and achieves an initial coulombic efficiency above 91%, with measured values reaching approximately 1994 mAh/g and 92.1%, respectively. The material exhibits a tap density of 1.22 g/cm³, a BET surface area of 3.62 m²/g, and a median particle size (D50) around 8.6 μm, with low magnetic impurity content. For reliable half-cell evaluation, it is recommended to use carbon-coated copper foil and an NCM-type electrolyte, with electrode baking at 85 °C for four hours. This material is suitable for researchers investigating advanced anode formulations for next-generation lithium-ion cells.

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, porous carbon skeleton, with a capacity of over 1800mAh/g, and high coulombic efficiency for the first time
