Abstract LiNixMnyCo1-x-yO2 (NMC) is considered the most appealing cathode material due to its high energy density and low cost. However, the stability and safety concerns, caused by the degradation of polycrystalline cathode materials during cycling, have restricted their practical applications. To overcome this shortcoming, converting polycrystalline cathode to high-performance single-crystal cathode materials becomes an appealing solution. Here, a universal etching approach is firstly develope...

Abstract Successful synthesis of novel multi-component metal composites with a unique structure can effectively promote the electrochemical performance improvement of supercapacitors. Herein, three-dimensional (3D) ZnCo2O4@NiCoMn-S(denoted as ZnCo2O4@NxCyMzS-X, x, y and z refer to the element content ratio, X refers to the number of cycles) arrays growing on nickel foam (NF) were synthesized with facile hydrothermal and electrodeposition processes. The structure of samples is regulated with the ...

Abstract null null Nickle-rich LiNi0.8Co0.1Mn0.1O2 (NMC 811) cathode material exhibits engaging properties in high energy density and low cost, making it great potential for the next generation high-energy all-solid-state lithium batteries (ASSLBs). However, NMC 811 suffers from severe surface electrochemical, chemical, and voltage incompatibility towards solid-state electrolytes (SSE), especially thiophosphate-based electrolytes like Li6PS5Cl. Although diverse coating methods have been made to ...

While lithium, manganese-rich (LMR) layered oxide cathode materials offer high energy density (>900 Wh kg-1) and low cost, LMR is susceptible to continuous capacity and voltage decay from the oxygen migration and side reaction with aqueous electrolyte at high voltage. Herein, the integration of Na/F co-doping (CD) and AlF3 coating on LMR is achieved without the need of complex atomic layer deposition. Akin to pristine and CD samples, CD with 1 wt % AlF3 (CD-1.0 wt %) shows excellent electrochemi...

In Lead-acid batteries, there are significant efforts to enhance battery performance, mainly by reducing metal impurities that negatively affect battery performance. Currently implemented impurity analysis requires significant time and effort. Wet chemical preparation method is not only hazardous due to the extensive use of acids, but generates environmental pollutants and hazardous waste which require more costly and comprehensive disposal processes. In industry, it is desirable to reduce sampl...

The ZnCo2O4@NiCo2S4@PPy core-shell nanosheets material is prepared by directly growing leaf-like ZnCo2O4 nanosheets derived from the metal-organic framework (MOF) on Ni foam (NiF) via chemical bath deposition and annealing methods and then combining with NiCo2S4 and PPy via electrodeposition methods. The special core-shell structure formed by MOF-derived ZnCo2O4, NiCo2S4 and PPy creates a bi-interface, which could significantly promote the contact between electrode and electrolyte, provide more ...

Summary Lithium-ion batteries (LIBs) have become one of the main energy storage solutions in modern society. The application fields and market share of LIBs have increased rapidly and continue to show a steady rising trend. The research on LIB materials has scored tremendous achievements. Many innovative materials have been adopted and commercialized by the industry. However, the research on LIB manufacturing falls behind. Many battery researchers may not know exactly how LIBs are being manufact...
