How Graphene-CNT Hybrids Improve Lithium-Ion Battery Conductivity

🔬 Introduction

In the race to improve lithium-ion battery performance, conductive additives play a crucial role. Traditional choices like carbon black are cheap but limited. Enter the graphene-carbon nanotube (CNT) hybrid — a game-changing material offering high conductivity, structure integrity, and compatibility.

⚙️ Why Graphene + CNT?

• Graphene: 2D sheet, large surface area, excellent lateral conductivity

• CNTs: 1D tubes, form interlinked conductive networks in 3D
  Together, they create a 3D electron highway with better particle bridging, reducing the need for binder and improving charge transport.

🔋 Performance Benefits

• Up to 70% lower internal resistance in LFP cathodes

• Better performance under high C-rates

• Improved cycle life in low-temperature environments

• Reduced additive loading = higher active material ratio

📦 Product Example: GR-G16C

• Avg. Particle Size: 16 µm

• SSA: ~121 m²/g

• Format: dry powder or slurry form
  Ideal for Li-ion and LiFePO₄ systems. Pre-blended with dispersant upon request.
