Morphology-dependent performance of Zn2GeO4 as a high-performance anode material for rechargeable lithium ion batteries

摘要: In this study, the electrochemical performance of hollow Zn2GeO4 nanoparticles as an anode material for lithium-ion batteries (LIBs) has first time been investigated and compared to other morphology-type materials with a solid nanorod structure. The results show that lithium-storage is morphology-dependent presence voids beneficial enhance charge–discharge capacity at different current densities. Specifically, approximately 200 mA h g−1 higher than nanorods after 60 discharge–charge cycles density such high (ca. 1200 g−1) in front rank three times commercial graphite-based anodes (372 g−1). Moreover, better rate specific 300 2000 comparison nanorods. not only lower charge transfer resistance by facilitating diffusion, but also effectively buffer against local volume changes. Therefore, considering easy environmentally friendly synthesis (high reversible good capacity), are very promising candidate high-performance LIBs.
