Enhanced rate capability of interconnected LiNi1/3Mn1/3Co1/3O2 (NMC) nanoparticles fabricated via electrospinning method is presented. Interconnected NMC nanoparticles have a discharge capacity of 175 mAh g−1 at 0.1C and 94 mAh g−1 at 1C. Similar nanoparticular NMC cathode without interconnections, fabricated by co-precipitation method, has a capacity of 22 mAh g−1 at 1C. Interconnected NMC nanoparticles have good cycling stability after 500 cycles at 1C with a capacity of ~17 mAh g−1. Though the rate capability of Interconnected NMC nanoparticles is superior, cycling stability is similar across cathodes, indicating that capacity fading is intrinsic to the cathode.
