Research progress on metal selenide negative electrode materials for LR6 alkaline battery
Recently, the internationally renowned journals Advanced Materials (IF=21.95) and Advanced Energy Materials (IF=21.875) have successively published a series of research works on metal selenide negative electrode materials for LR6 alkaline battery by Professor Ji Xiaobo's team from the School of Chemistry and Chemical Engineering of Central South University. Professor Ji Xiaobo is the corresponding author of the paper, and 2016 doctoral student Ge Peng is the first author of the paper.
Professor Ji Xiaobo's team has long been committed to the research of new battery materials. Studies have found that the conversion reaction, as one of the three major reaction mechanisms, has a volume expansion smaller than the alloying reaction and a sodium storage capacity greater than the embedding reaction. It is currently considered to be a new battery material system with great potential. This type of material mainly includes metal oxides, sulfides, selenides, phosphides, etc. Due to the toxicity of phosphide raw materials and the limitations of the synthesis method, the current main conversion materials are mainly concentrated on metal-based sixth main group compounds. Among them, due to the strong electronic conductivity (1×10-5Sm-1) and weak electronegativity (2.5) of Se element, metal selenide has the potential to have excellent charge-discharge specific capacity and cycle stability.
Professor Ji Xiaobo's team has made new progress in designing and regulating the interface characteristics of metal selenium-based materials and carbon matrices. Through self-assembly, the linear basic nickel carbonate (Ni-Pr) was designed and synthesized, and the pyrrole monomer was adsorbed into it by its large specific surface area for polymerization reaction. Using Se single substance and Kirkendall effect at high temperature, a carbon-coated multi-level hollow structure was successfully generated. The system successfully introduced metal oxygen-carbon bonds and derived double carbon layer structures, which effectively improved the reaction reversibility of the material, alleviated the volume expansion of the material, and deepened the depth of electrochemical reaction. It has shown excellent performance in the field of sodium ion energy storage. This work has important guiding significance for the design and derivation of metal-based materials. The research results were recently published in Advanced Energy Materials (2018, DOI: 10.1002/adma.201803035) (IF=21.875).
In addition, the team found that the iron-based Prussian blue-like structure has the characteristics of a wide range of raw material sources and simple production processes, but the internal interstitial crystal water and relatively weak redox couple Fe2+/Fe3+ of the material itself lead to poor cycle stability and rate performance of this type of material. By replacing part of the iron-based elements with cations (cobalt, nickel, manganese), the crystallinity, particle size, and electrochemical properties of the Prussian blue-like materials are effectively regulated. Thanks to the excellent physicochemical stability, enhanced kinetic coefficient and "zero strain" structure, the prepared Ni-FePBAs can still maintain a capacity of 81mAhg-1 at a current density of 1.0Ag-1. In addition, by pyrolysis selenization, double carbon layer core-shell structure nickel-iron-based selenide is further derived, showing excellent cycle stability and fast charge and discharge capabilities. By using nickel-based Prussian blue and the corresponding selenide derived from it as positive and negative electrode materials, the corresponding all-electric system was assembled, showing an outstanding charge-discharge specific capacity of 302.2 mAh g-1 (1.0 Ag-1). The research results were recently published in Advanced Materials (2018, DOI: 10.1002/adma.201806092) (IF=21.95).
