Summary: A self-driven and energy-saving Ni anode-based electrochromic device (ECD) using Prussian blue as electrochromic material is developed. It can be colored by solar energy during the day and spontaneously bleach at night using the internal redox potential, without any extra energy input. Compared to ECDs with high Ni2+ or high K+ concentration in the electrolyte, the Ni-based ECD with equal amount of K+ and Ni2+ exhibits higher optical contrast, faster coloration response time, and better stability.

Summary: This mini review briefly discusses the developments on the application of polypyridyl-based copper complexes in dye-sensitized solar cells (DSSCs). Copper complexes can be used as dye sensitizers and/or as redox mediators in DSSCs. The abundance and low cost of copper make it a cheaper and non-toxic alternative to the commonly used iodide/triiodide electrolyte redox couple and the expensive and rare ruthenium-based dyes.

Summary: A new graphene/TiO2 decorated N-doped carbon foam as a three-dimensional current collector for high loading sulfur cathodes is proposed, providing enough space for active sulfur and strong polysulfide confining ability. The 3D porous conductive structure allows rapid mass mobilization and boosts electron transfer kinetics, leading to a remarkable capacity of 788 mA h g(-1) for the sulfur cathode after 100 cycles with a high sulfur loading of 7.4 mg cm(-2). This work offers insights for multifunctional current collectors in thick sulfur cathodes for Li-S batteries.
