Hard carbon nanoparticles as high-capacity, high-stability anodic materials for Na-ion batteries

Hard carbon nanoparticles (HCNP) were synthesized by the pyrolysis of a polyaniline precursor. The measured Na+ cation diffusion coefficient (10−13–10−15cm2s−1) in the HCNP obtained at 1150°C is two orders of magnitude lower than that of Li+ in graphite (10−10–10−13cm2s−1), indicating that reducing...
