Perovskite Oxides for Energy Applications

Abstract

Industrial and population growth is constantly increasing energy consumption. Since 81.3% of consumed energy is produced from fossil fuels, the high pollution and emission rates are leading to climate changes resulting in extreme weather conditions. The development of new materials and technology is necessary to achieve sustainable societal growth and development. In the field of new materials, perovskites are the main subject of much scientific research conducted in the last decade. Perovskites are usually divided into two groups: halides and oxides. The application of perovskite halides in photovoltaic and solar cells is already well-known and investigated. On the other hand, perovskite oxides do not possess optical and light-absorption properties comparable to perovskite halides, but they have promising electrical and magnetic properties and high reducibility rates. This review is dedicated to the perovskite oxides, preparation methods of this material and their application for energy transformation and storage applications. The perovskite oxides have high potential as working materials in solid oxide fuel cells (SOFC), Ca batteries, thermochemical energy storages (TCES) and ambient temperature magnetic refrigerators (MR).

Hydrothermal Synthesis and Electrochemical Performance of Mesoporous La2CrMnO6 Double Perovskite for Energy Storage Applications

“…[7][8][9][10][11][12] The diverse range of applications of perovskite materials is attributed to their high thermal stabilities, outstanding sensitivities, energy storage capabilities, facile synthesis, high accessibilities, and selectivity. [13][14][15] Electrochemical storage systems require high energy density, power density, cycling stability, and low-cost materials. [16,17] Supercapacitors have gained widespread attention due to their ability to deliver higher energy density than capacitors and better cyclic stability than batteries.…”
