Abstract

Amorphous and crystalline Zn₂GeO₄ nanoparticles were prepared and characterized as anode materials for Li-ion batteries. A higher reversible specific capacity of 1250mAh/g after 500 cycles and excellent rate capability were obtained for amorphous Zn₂GeO₄ nanoparticles, compared to that of crystalline Zn₂GeO₄ nanoparticles. Small particle size, amorphous phase and incorporation of zinc and oxygen contribute synergetically to the improved performance by effectively mitigating the huge volume variations during lithiation and delithiation process.
