New wide band gap donor for efficient fullerene

Insight into the Fading Mechanism of the Solid-Conversion Sulfur Cathodes and Designing Long Cycle Lithium–Sulfur Batteries


*

The solid–solid sulfur reaction via the cathode electrolyte interface (CEI) strategy can theoretically reduce the electrolyte/sulfur ratio & obtain a high energy mật độ trùng lặp từ khóa battery. The stability of the CEI is strongly related lớn the nội dung of sulfur và the amount of electrolyte. Only when the sulfur content matches the pore volume of the carbon host, a stable CEI and long lifespan can be obtained.

Organo-tin halide perovskite photovoltaics without encapsulation, tested in ambient air under electrical load exhibit exceptional stability when using a bathocuproine | copper cathode in an inverted device architecture. It is shown that compact copper electrodes are far more resistant lớn corrosion by iodine gas, toward adverse morphological evolution, và are less permeable to oxygen and water than conventional silver cathodes.
