In the field of solid state battery, single-walled carbon nanotubes are widely studied and applied as conductive agents. Solid state battery is a battery system that uses solid electrolytes to replace traditional liquid electrolytes. Conductive agents play a role in promoting charge transfer and improving battery performance in solid state battery. The following are the main applications of single-walled carbon nanotubes as conductive agents in solid state battery:

1. Improving the conductivity of battery: The ion and electron transmission of  solid state battery require the establishment of a good charge transfer channel between the electrolyte and the electrode. Single-walled carbon nanotubes have excellent conductivity and high specific surface area, which can provide a good charge transfer path, reduce battery internal resistance, and improve battery conductivity.

2. Enhancing the stability of electrode structure: In solid state battery, the stability of charge transfer is crucial for long-term cycling and high rate charging and discharging.As conductive agents, single-walled carbon nanotubes can enhance the structural stability of electrode materials, prevent electrode debonding, cracking, or deformation, thereby improving the cycle life and performance stability of battery.

3. Promoting ion diffusion: Solid state electrolytes in solid state battery play a crucial role in ion transport. The high specific surface area and pore structure of single-walled carbon nanotubes can provide a larger surface reaction area and diffusion channels, which helps promote rapid diffusion of ions in the electrolyte and improve the ion transport performance of the battery.

4. Inhibiting the aggregation and volume change of electrode materials: In  solid state battery, the aggregation and volume change of electrode materials can have adverse effects on battery performance. Single-walled carbon nanotubes can form a network structure in electrode materials, suppress the aggregation of electrode materials, and provide certain flexibility and compressibility, which helps alleviate the volume change stress of electrode materials and improve the cycle life and stability of batteries.
