Tuning Pore Dimensions of Mesoporous Inorganic Films by Homopolymer Swelling

Reid, Barry; Alvarez-Fernandez, Alberto; Schmidt-Hansberg, Benjamin; Guldin, Stefan

The functionality and applications of mesoporous inorganic films are closely linked to their mesopore dimensions. For material architectures derived from a block copolymer (BCP) micelle coassembly, the pore size is typically manipulated by changing the molecular weight corresponding to the pore-forming block. However, bespoke BCP synthesis is often a costly…

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…

Local mobility in electrochemically inactive sodium in hard carbon anodes after the first cycle

Jensen, Anders C. S.; Olsson, Emilia; Au, Heather; Alptekin, Hande; Yang, Zhengqiang; Cottrell, Stephen; Yokoyama, Koji; Cai, Qiong; Titirici, Maria-Magdalena; Drew, Alan J.

Sodium ion batteries are a promising alternative to current lithium ion battery technology, providing relatively high capacity and good cycling stability at low cost. Hard carbons are today the anodes of choice but they suffer from poor rate performance and low initial coulombic efficiency. To improve the understanding of the…

Tin-based perovskite solar cells (PSCs), with more consummate optical band gaps, lower exciton-binding energies, and higher charge-carrier mobility, have not attracted tremendous research efforts compared with the lead-based ones that have a record power conversion efficiency (PCE) of 24.2%. The major challenges for Sn-based research are significantly low open-circuit voltage,…

Adil, Muhammad Abdullah; Zhang, Jianqi; Wang, Yuheng; Yu, Jinde; Yang, Chen; Lu, Guanghao; Wei, Zhixiang

An optimized bulk heterojunction (BHJ) interface, certifying enhanced exciton-splitting, charge separation and recombination inhibition, is vastly desired to obtain high power conversion efficiencies (PCEs). Herein, the ternary strategy has been employed to effectively modify the phase separation between the J71:ITIC blend by incorporating a 3D aggregation-induced emission (AIE) material,…
