Abstract
En 中文
The discovery of new chemistries superior to modern lithium intercalation cathodes is of great scientific and technological importance. The cathodes play a key role in the performance of lithium-ion batteries (LIB). While layered oxide cathodes deliver high capacity, polyanion compounds show structural stability, operational safety, tunable redox potentials, etc. The growing applications of LIBs, along with a decrease in the abundance of Li sources and an increase in their cost, have led to postlithium-battery era, where sodium-ion batteries (SIBs) are a suitable alternative for full/partial substitutions of LIBs and are most promising for large-scale applications, independent of size/weight restriction, in particular, for stationary energy storage devices. However, the number of known Na-based cathode materials with energy density close to Li-based materials is limited that suggests searching for new intercalation materials. Recently, studies of mixed polyoxyanion cathodes have been initiated with the aim of further enriching the chemistry by combining two types of polyoxyanion units (so called 'anionic engineering'). This cathode family may open new framework-structured insertion materials, capable of multiple electron redox reaction and appropriate potential for high voltage operation, thereby increasing energy density. In this review, we report on a series of new mixed polyoxyanion compounds for LIBs and SIBs. A comprehensive list of these materials along with their crystal structure, synthesis methods, and electrochemical characteristics is provided.
