In a systematic study toward solid polymer electrolytes in lithium-metal anode cells, voltage noise in addressed by means of lithium surface pretreatment. The limiting factor of polarization is addressed by electrolyte conductivity tuning. The examination of the role of electrolyte infiltration into the cathode on cell performance leads to a practical...

A strategy for highly efficient and robust perovskite solar cells via a greenable slot-die process is reported. Locally supersaturated perovskite ink based on low-toxic dimethyl sulfoxide is prepared by rheological engineering with a small amount of 1,2-dichlorobenzene . The findings present a strategy for designing perovskite inks and a pathway toward...

A general “engraving in aprotic medium” strategy is put forward to realize Zn foil pretreatment in terms of anode stability. The thus-produced 3D porous Zn surface is able to mitigate side reaction and dendritic formation, ensuring the excellent electrochemical performance and allowing the practical pursuit of a Zn anode. Abstract Zn foil...

The electrode/electrolyte interface of polyanionic Na-insertion compounds Na3V2(PO4)3 (NVP) and Na3V2(PO4)2F3 (NVPF) is investigated by the complementary use of electrochemical quartz crystal microbalance and operando infrared fiber evanescent wave spectroscopy combined with molecular dynamics simulations. An unusual mass uptake/depletion signal is...

Fundamental knowledge of the calendering process for large-scale electrode production is critically required to optimize electrochemical energy storage manufacturing. In this review the way forward to optimize porosity, adhesion, thickness, and wettability of electrodes by calendering is demonstrated, which is expected to lead to improved volumetric...

A high-performance and stable perovskite solar cell is demonstrated by using a fluorinated indoloindole (IDIDF)-based linear-type hole transporting material. The perovskite solar cell using IDIDF2 achieves high performance in non-doped (23.16%) and doped conditions (24.24%), respectively. In addition, the corresponding devices show superior device...
