They used freestanding sheets made of carbon nanotubes - bucky papers - for sandwiching silicon nanoparticles. These nanotubes form a quasi-three-dimensional structure and hold silicon nanoparticles together even after 100 cycles and mitigate electrical resistance arising from breaking of particles. The sandwiched silicon anode was able to withstand discharging rates as high as 4C. • Email to a friend • |
