摘要

本工作的目的是研究锗纳米线作为低温、高充电率锂离子电池负极材料。我们使用了一个完整的电池，阴极是基于NMC811，阳极是基于合成的锗纳米结构，结合所提出的电解质成分，我们证明了在低至- 40°C的温度下充电和循环电池的能力。研究结果表明，采用锗纳米线作为锂离子电池的负极材料，可以解决锂离子电池在零下温度下可逆、安全充电的问题。

Germanium Nanowires As Anode Material for Lithium-Ion Batteries With Ability To Charge At Subzero Temperatures

The aim of this work is to study of germanium nanowires as low temperature and high charging rate lithium-ion battery anode material. Using a full cell with a cathode based on NMC811 and an anode based on synthesized germanium nanostructures in combination with the proposed electrolyte composition, we demonstrate the ability to charge and cycle the battery at temperatures as low as −40 °C. The results generally indicate that using germanium nanowires as anode material in lithium-ion batteries may solve the problem of their reversible and safe charging at sub-zero temperatures.
