The "Final 2023 Critical Materials List" was determined by the United States Department of Energy (DOE), [5] with the Undersecretary for Science and Innovation involvement. . This list incorporates materials deemed critical for energy applications and minerals from the 2022 final list designated by the Department of the Interior through the United States Geological Survey (USG
Energy materials are used for energy harvesting, storage, and conversion. [ 1 ] [ 2 ] Applications of energy materials include photovoltaics , as well as piezoelectronics . The study of energy materials is usually interdisciplinary , uniting materials scientists , chemists , physicists , biologists , and engineers .
In March 2020, the Samsung Advanced Institute of Technology (SAIT) published research on an all-solid-state battery (ASSB) using an argyrodite-based solid-state electrolyte with a demonstrated energy density of 900 Wh L −1 and a stable cyclability of more than 1000 cycles, reaching for the first time a value close to the 1000 Wh L −1.
Many superconducting ceramic materials (the high temperature superconductors) have perovskite-like structures, often with 3 or more metals including copper, and some oxygen positions left vacant. One prime example is yttrium barium copper oxide which can be insulating or superconducting depending on the oxygen content.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Beryl, a mineral that contains beryllium, has been known since the time of the Ptolemaic Kingdom in Egypt. [37] Although it was originally thought that beryl was an aluminum silicate, [41] beryl was later found to contain a then-unknown element when, in 1797, Louis-Nicolas Vauquelin dissolved aluminum hydroxide from beryl in an alkali.

Advanced Energy Materials is a peer-reviewed scientific journal covering energy-related research, including photovoltaics, batteries, supercapacitors, fuel cells, hydrogen technologies, thermoelectrics, photocatalysis, solar power technologies, magnetic refrigeration, and piezoelectric materials.
Nuclear fuel process A graph comparing nucleon number against binding energy Close-up of a replica of the core of the research reactor at the Institut Laue-Langevin. Nuclear fuel refers to any substance, typically fissile material, which is used by nuclear power stations or other nuclear devices to generate energy.
