AI Technical Summary
Existing conductive material dispersion solutions for secondary battery electrodes, particularly those using carbon nanotubes, suffer from poor fluidity and dispersibility, leading to issues during transportation, storage, and electrode film formation, which affects the conductivity and lifespan of secondary batteries.
A resin composition for secondary battery electrodes is developed by controlling the product of complex elastic modulus and phase angle in a carbon nanotube dispersion solution, ensuring high dispersibility and fluidity, even when a binder resin is added, thereby forming a well-developed conductive network in the electrode film.
The solution provides secondary batteries with high output, capacity, and long lifespan by maintaining carbon nanotube fibers intact during the formation of the electrode film, enhancing the conductivity and reducing resistance.
