Abstract

image

Nanoconfinement of ultrasmall SnO2 particles in mesoporous carbon with suitable pore size is demonstrated as an efficient method for creating extremely long cycle-life anode battery materials. Exceptional rate capability, high Coulombic efficiency, and excellent cyclic reversibility are shown. The high capacity at high current rate and long cycling makes this composite a promising anode material for Li-ion batteries.
