Battery storage systems (BSSs) are emerging as pivotal components for facilitating the global transition toward transportation electrification and grid-scale renewable energy integration. Nevertheless, a significant research gap persists due to the lack of large-scale, publicly available field data from real-world BSS deployments, thereby hindering the advancement of state-of-the-art health monitoring

Current studies have highlighted the crucial role of spin in electrocatalytic reactions. Spin regulation can effectively reduce the energy cost of spin flipping and accelerate reactions. A recent work in Journal of the American Chemical Society by Zhang et al.1 reported the spin regulation on chiral Ag nanostructured films, which significantly enhances C2+ product formation in electrochemical CO2 reduction

In a recent issue of Chem, Professor Han and coworkers advance the anthracene-based solar energy storage materials capable of self-activated heat release through a cascading cycloreversion process, mimicking fossil fuel combustion and presenting new possibilities for scalable, renewable heat storage applications. This preview highlights two significant breakthroughs in molecular solar thermal energy

Dielectric polymers with capacitive energy storage capabilities are essential for advanced electronics and electrical systems. However, a persistent challenge lies in enhancing their energy density at elevated temperatures. Despite the exploration of high-glass transition temperature (Tg) polymers with superior dielectric-thermal stability, they face limitations in terms of low dielectric constant

The zinc-ion batteries are challenged by zinc dendrite, notorious side reactions, and poor performance at low temperatures. Here, we present a dual-salts tuned electrolyte exhibiting a wide temperature range (-60 to 25 ºC). The Zn(ClO4)2-based electrolyte with high hydrogen bond destruction ability and fast diffusion kinetics favors the application at ultralow temperatures. The introduction of Zn(OAc)2

Vacuum-assisted technology, favored for its low cost, environmental friendliness, and scalability, is widely used in perovskite solar cells and is a preferred choice for commercialized production. However, strong solvent extraction at the interface between the wet film and vacuum causes a thin perovskite film at the top surface and residual solvent at the buried interface, which results in film stratification

The exceptional cycling stability of lithium-ion batteries in electric vehicles and large-scale grid energy storage applications necessitates the use of accelerated aging tests for rapid assessment. Overdischarge stress is an effective approach to accelerate battery aging, whereas its impact on solid electrolyte interphase (SEI) and battery aging performance remains elusive. Herein, the whole picture

The application of environmentally friendly and economical aqueous zinc (Zn) metal batteries (ZMBs) is severely limited by critical issues associated with Zn anodes, including dendrite growth, hydrogen evolution reaction and corrosion. Hence, many improvement methods, such as electrolyte additives, mainly focus on the protection of Zn anodes. Herein, owing to the abundance of zincophilic functional
