| description | <p dir="ltr">Hybrid composites between Germanium (Ge) and carbonaceous materials have been extensively studied due to the carbonaceous’ component’s ability to mitigate the intrinsic problems pertaining to Ge-based anodes. The mitigation of reduced cycling ability and rate capability allows for the unhindered benefit of higher capacities in Ge-carbonaceous composite anodes. Here, the effect of different Ge mass loading on electrochemical performance is studied on a GeO<sub>2</sub>/Ge/r-GO composite made using controlled microwave radiation of ball-milled Ge and sonicated dispersion of graphene Oxide (GO) as a lithium battery anode. The composite anode at Ge 25% showed greatest cycling retention with 91% after 100 cycles and an average specific capacity of 300 mAh/g (1600 mAh/g Ge). At 75% Ge mass loading the anode suffered with limited cycling retention of 57.5% at the cost of greater specific capacities. The composite at 50% Ge attained advantageous characteristics of both composites with a stable cycling performance of 71.4% after 50 cycles and an average specific capacity of 400 mAh/g (1067 mAh/g Ge, all conducted at a current density of 100 mA/g). A positive linear correlation is revealed for increasing Ge mass loadings and specific capacities in Ge-carbonaceous as anode materials.</p><h2>Other Information</h2><p dir="ltr">Published in: Materials Today Communications<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.mtcomm.2022.103151" target="_blank">https://dx.doi.org/10.1016/j.mtcomm.2022.103151</a></p> |
