Carbon Nanofiber-AH

Products

Whisker carbon nanotubes feature a small specific surface area, enabling direct powder addition with excellent dispersion properties to enhance cell consistency. Whisker carbon nanotubes contain minimal impurities, reducing self-discharge while improving cell consistency and safety. Their long length (approximately 6 μm) suppresses active material expansion during battery charge/discharge cycles and maintains lithium-ion conduction pathways within the active material. This ensures uninterrupted electron and ion transport, extending cycle life and enhancing battery safety. The multi-layered hollow microstructure of whisker carbon nanotubes allows both positive and negative electrodes to absorb more electrolyte. This facilitates smooth and rapid lithium-ion insertion, supporting high-rate charge/discharge capabilities. High electrical and thermal conductivity also enhances the thermal conductivity coefficients of both electrodes, facilitating heat dissipation. Translated with DeepL.com (free version)
