The concept of multi-principal component has created promising opportunities for the development of novel high-entropy ceramics for extreme environments encountered in advanced turbine engines, nuclear reactors, and hypersonic vehicles, as it expands the compositional space of ceramic materials with tailored properties within a single-phase solid solution. The unique physical properties of some high-entropy carbides and borides, such as higher hardness, high-temperature strength, lower thermal conductivity, and improved irradiation resistance than the constitute ceramics, have been observed. These promising properties may be attributed to the compositional complexity, atomic-level disorder, lattice distortion, and other fundamental processes related to defect formation and phonon *** manuscript serves as a critical review of the recent progress in high-entropy carbides and borides, focusing on synthesis and evaluations of their performance in extreme high-temperature, irradiation, and gaseous environments.

Mn-based Prussian blue analogues(Mn-PBAs),featuring a three-dimensional(3D)metal-organic framework and multiple redox couples,have gained wide interests in Zn-ion batteries(ZIBs).However,owing to the Jahn-Teller distortion and disproportionation reaction of Mn^(3+),these materials suffer from poor electrochemical performances and inferior structural ***,we prepare a typical high-entropy Prussian blue analogue(HE-PBA)with increased configuration entropy through integrating five transition metal elements of Mn,Co,Ni,Fe and Cu into the nitrogen-coordinated-M-lattice ***,the HE-PBA presents enhanced uptake of Zn^(2+)with 80 mAh·g^(−1)compared to those medium-entropy PBAs,low-entropy PBAs and conventional PBAs,which can be assigned to“cocktail”effect of multiple transition metal active redox ***,a phase transition process from monoclinic phase to rhombohedral phase occurs in HE-PBA cathode,resulting in a stable structure of MN6(M=Mn,Co,Fe,Ni,Cu)and ZnN4 co-linked to FeC6 through the cyanide ***,the advantages of entropy-driven stability are also confirmed by the calculated reduction energy and the density of states between HE-PBA and KMn[Fe(CN)6](KMnHCF).This work not only presents a high-performance HE-PBA cathode in ZIBs,but also introduces a novel concept of high entropy benefiting for designing advanced materials.

Rechargeable metal-ion batteries, such as lithium-ion batteries(LIBs) and sodium-ion batteries(SIBs),have raised more attention because of the large demand for energy storage solutions. Undoubtedly, electrode materials and electrolytes are key parts of batteries, exhibiting critical influence on the reversible capacity and span life of the metal-ion battery. Nonetheless, researchers commonly express concerns regarding the stability of both electrodes and electrolytes. Given its commendable stability attributes,high-entropy materials have garnered widespread acclaim and have been applied in many fields since their inception, notably in energy storage. However, while certain high-entropy designs have achieved substantial breakthroughs, some have failed to meet anticipated outcomes within the high energy density energy storage materials. Moreover, there is a lack of comprehensive summary research on the corresponding mechanisms and design principles of high-entropy designs. This review examines the current high-entropy designs for cathodes, anodes, and electrolytes, aiming to summarize the design principle,potential mechanisms, and electrochemical performance. We focus on their structural characteristics,interface characteristics, and prospective development trends. At last, we provide a fair evaluation along-side succinct development suggestions.
