Unveiling the role of hydrothermal carbon dots as anodes in sodium-ion batteries with ultrahigh initial coulombic efficiency

Xie, Fei; Xu, Zhen; Jensen, Anders C. S.; Ding, Feixiang; Au, Heather; Feng, Jingyu; Luo, Hui; Qiao, Mo; Guo, Zhenyu; Lu, Yaxiang; Drew, Alan J.; Hu, Yong-Sheng; Titirici, Maria-Magdalena

Hard carbon materials are regarded as the most promising anode materials for sodium-ion batteries (SIBs) due to their best cost-effectiveness. However, their relatively low specific capacity and initial Coulombic efficiency (ICE) compared with the graphite anode in lithium-ion batteries still limit the energy density for further development. Thus, it is…

Facile Route for the Fabrication of Polypropylene Separators for Lithium-Ion Batteries with High Elongation and Strong Puncture Resistance

Kang, Jian; Chen, Dandan; Xiong, Bijin; Zheng, Nan; Yang, Feng; Xiang, Ming; Zheng, Zhuo

A facile route for fabrication of polypropylene separators for lithium-ion batteries with high elongation and strong puncture resistance has been proposed in this work. Polypropylene separators immersed in paraffin wax have been prepared to introduce small molecules into separators. The influence of small molecules on mechanical properties of separators is…

Effect of the substrate temperature during gold-copper alloys thin film deposition by magnetron co-sputtering on the dealloying process

Chauvin, Adrien; Horak, Lukas; Duverger-Nédellec, Elen; Dopita, Milan; Tessier, Pierre-Yves; El Mel, Abdel-Aziz

Nanoporous gold is of great interest for many applications due to its three dimensional interconnected porosity at nanoscale. Among all currently use techniques to obtain nanoporous gold, dealloying is one of the most used method to create a well-controlled nanoporous morphology. Only few studies report on the creation of nanoporous…

Nafion/Protic Ionic Liquid Blends: Nanoscale Organization and Transport Properties

Danyliv, Olesia; Martinelli, Anna

In this work, the possibility of using the protic ionic liquids N-ethylimidazolium trifluoromethylsulfonate, , and N-ethylimidazolium bis(trifluoromethylsulfonyl)imide, , as charge carriers in appropriately modified Nafion membranes has been investigated. The superior thermal stability of ionic liquids, as compared to that of water-based electrolytes, hypothetically offers a…

Hard–Soft Carbon Composite Anodes with Synergistic Sodium Storage Performance

Xie, Fei; Xu, Zhen; Jensen, Anders C. S.; Au, Heather; Lu, Yaxiang; Araullo‐Peters, Vicente; Drew, Alan J.; Hu, Yong-Sheng; Titirici, Maria-Magdalena

A series of hard–soft carbon composite materials is produced from biomass and oil waste and applied as low-cost anodes for sodium-ion batteries to study the fundamentals behind the dependence of Na storage on their structural features. A good reversible capacity of 282 mAh g−1 is obtained at a current density…
