Nature Materials is a multidisciplinary journal aimed at bringing together cutting-edge research across the entire spectrum of materials science and technology. Nature Materials covers all applied and fundamental aspects of the synthesis/processing, structure/composition, properties and performance of materials. Nature Materials provides a forum for the development of a common identity among materials scientists while encouraging researchers to cross established subdisciplinary lines. To achieve this, Nature Materials takes an interdisciplinary, integrated and balanced approach to all areas of materials research while fostering the exchange of ideas between scientists involved in different communities.

Electrochemomechanical failure in layered oxide cathodes caused by rotational stacking faults
Nature Materials, Published online: 03 May 2024; doi:10.1038/s41563-024-01899-9
Degradation is one of the most common causes of capacity deterioration in high-energy-density cathodes. Rotational stacking faults in layered lithium transition-metal oxides are shown to play a critical role in determining their structural and electrochemical stabilities.

Mobile iodides capture for highly photolysis- and reverse-bias-stable perovskite solar cells
Nature Materials, Published online: 29 April 2024; doi:10.1038/s41563-024-01876-2
Iodide-related defects pose serious challenges to the irradiation, thermal, light or reverse-bias stabilities of perovskite solar cells. Here, the authors find that by using the iodide/polyiodide capture and confine effects of perfluorodecyl iodide interfacing with perovskites, inverted perovskite solar cells achieve much improved stabilities.
