Abstract |
Silicon nanoparticle is promising anode material for lithium-ion batteries(LIB) due to highest theoretical capacity (4200 mAhrg-1). However, instability issue during lithiation-delithiation and its low conductivity remain in the existing nanostructured silicon. To improve electrochemical stability, we synthesize Mesoporous silicon nanoparticle(mSiNP) by surface protected-magnesiothermic reduction. as-synthesized silicon combines Sulfur-doped graphene oxide with cyclized polyacrylonitrile(c-PAN) for enhance the electronic conductivity. |
