Abstract

Cathode Materials

In article number 2404929, Kaipeng Wu and co-workers demonstrate that the anomalous lithiation plateau of LiFe_yMn_1−yPO₄ originates from stress concentration occurring at the interface between particle surface and bulk during rapid lithium insertion. This stress alleviates the lattice distortion of MnO₆ octahedra, thereby enhancing the Li⁺ diffusion kinetics and eventually unlocking the capacity of Mn³⁺.

期刊介绍： Established in 2011, Advanced Energy Materials is an international, interdisciplinary, English-language journal that focuses on materials used in energy harvesting, conversion, and storage. It is regarded as a top-quality journal alongside Advanced Materials, Advanced Functional Materials, and Small. With a 2022 Impact Factor of 27.8, Advanced Energy Materials is considered a prime source for the best energy-related research. The journal covers a wide range of topics in energy-related research, including organic and inorganic photovoltaics, batteries and supercapacitors, fuel cells, hydrogen generation and storage, thermoelectrics, water splitting and photocatalysis, solar fuels and thermosolar power, magnetocalorics, and piezoelectronics. The readership of Advanced Energy Materials includes materials scientists, chemists, physicists, and engineers in both academia and industry. The journal is indexed in various databases and collections, such as Advanced Technologies & Aerospace Database, FIZ Karlsruhe, INSPEC (IET), Science Citation Index Expanded, Technology Collection, and Web of Science, among others.
