Key Highlights
•
A new chemical additive, based on a fused-ring molecule, can simultaneously guide zinc metal to deposit smoothly and trap harmful iodine-based molecules inside a battery. This dual-action approach creates zinc-iodine batteries that are far more durable and resistant to failure, paving the way for safer, longer-lasting grid-scale energy storage.

Adding the lightweight element boron to sodium-ion battery cathodes strengthens their internal structure and creates a protective surface layer, which prevents damaging phase changes and side reactions with the electrolyte. This boron-chemistry engineering stabilizes the battery material during charging and discharging, offering a clear design strategy for building high-performance, cost-effective sodium-ion batteries for large-scale energy storage.

Researchers have redesigned a cooling technology that uses a reversible chemical process where a solid absorbs a liquid to create cooling, which can also be reversed to provide heating. This sorption-driven dissolution cycle provides a sustainable alternative to conventional refrigerants, with the potential to significantly reduce greenhouse gas emissions from air conditioning and thermal storage systems.
