| Abstract Scope |
Herein, for the first time, we first proposed a coating method of direct drip coating (DDC) on graphene paper current collectors. We have realized the electrochemical performance of gallium (Ga) that cycling with a specific capacity of 150 mAh g-1 after 1200 cycles at a current of 0.5 A g-1 at room-temperature. And to clarify the influence of Ga agglomerating on electrochemical performance in the process of charge/discharge, Gallium nanoparticles (Ga@NPs) and gallium reduced graphene oxide (Ga@RGO) have been studied in this work. At 40 ℃, Ga@RGO anodes show excellent cycling capability with a considerable specific capacity around 100mAh g-1 after 700 cycles at a current of 1 A g-1. has been realized. The existed RGO around Ga can protect small Ga droplets from agglomerating and stop G |
