Abstract

A 3D carbon/ZnO nanomembrane foam anode with practical ZnO loading leads to high areal capacity and long term stability.

Cycling-Induced Capacity Increase of Graphene Aerogel/ZnO Nanomembrane Composite Anode Fabricated by Atomic Layer Deposition

“…2b. For GAZ300 and GAZ100, the characteristic diffraction peaks of ZnO (100), (002), (101), (102), (110), (103), (112), and (201) are clearly exhibited in XRD patterns (PDF#36–1451) [21], suggesting that ZnO nanomembranes coated on GA surfaces can maintain the hexagonal wurtzite structure. However, very weak diffraction peaks can be distinguished in GAZ20 because the content of ZnO is too low.…”

“…However, ZnO suffers from large volume expansion/contraction (~ 163%) and poor conductivity, thus leading to fast capacity fading and poor cycling performance [8, 19]. Various strategies have been promoted to solve these problems, including the use of ZnO nanostructures (nanorod arrays [20] and nanosheets [7]) and carbon-based composites [21, 22]. Zhao et al [21] fabricated three-dimensional carbon/ZnO nanomembrane composite foam through an immersing process.…”

Zhao et al [21] fabricated three-dimensional carbon/ZnO nanomembrane composite foam through an immersing process. The composites could maintain more than 92% of the initial capacity after 700 cycles at 2 A g −1 because of the flexibility of ZnO nanomembranes and the effective electron/ion transport through carbon foam.…”

Atomic layer deposition of ZnO/TiO2 nanolaminates as ultra-long life anode material for lithium-ion batteries

“…ALD has been used to improve the performance of ZnO anodes via depositing active ZnO onto carbon based supporters (graphene, carbon black, carbon foam, etc.) 12,35 and surface modification 36 . For example, Zhao et al .…”

“…For example, Zhao et al . reported that 3D carbon/ZnO nanomembrane foam prepared by ALD can retain 92% capacity after 700 cycles at 2 A g −1 and deliver a remarkable areal capacity of 4.3 mAh cm −2 35 . Lu et al .…”
