Abstract

Abstract:

Commercial graphite anodes for lithium-ion batteries can’t meet the increasing demand for high energy density due to their low theoretical specific capacity（372 mA·h/g ）.The Ge anode material is considered a promising material due to its higher theoretical specific capacity （about 1 600 mA·h/g）.Unfortunately,the Ge anode material has a huge volume change during the charge and discharge process,exhibiting poor electrochemical performance.Therefore,a unique Ge-based composite anode was rationally designed and prepared.First,the organic-inorganic hybrid Ge-Fe-O_x/EDA nanowires were prepared by solvothermal method and then coated with dopamine.Subsequently,FeGe/FeGe₂ alloy phase was formed in situ and carbon coating was formed on the surface by high-temperature roasting,so as to prepare the encapsulated Ge/FeGe/FeGe₂@C nanowire irongermanium alloy anode.The unique structure effectively improved the conductivity of the Ge-based anode material and suppressed the volume change,so it exhibited excellent rate performance（the discharge capacity was 450 mA·h/g at the current density of 5 A/g） and excellent long cycle stability（achieving a high discharge capacity of 547 mA·h/g at 1 A/g after 400 cycles）.

Key words: lithium-ion batteries, Ge-based anode, nanowires, coating, nanoconfined encapsulation
