Effect of Different Electrolytes on MnO₂ Anodes in Lithium-Ion Batteries

Abstract

In this study, three most commonly used commercial electrolyte compositions were selected to investigate the effect of different electrolyte solvents on lithium-ion batteries (LIBs) with MnO 2 anodes, including 1

Review on Action Mechanism and Characterization of Natural/Artificial Solid Electrolyte Interphase of Lithium Battery: Latest Progress and Future Directions

“…They used electrochemical impedance spectroscopy, and other measurement methods to add DTD and MMDS electrolyte additives were tested. The results show that DTD can improve the initial Coulombic efficiency of the battery, MMDS significantly improves the long cycle life of the battery, and the linear quantitative combination of the two electrolytes can superimpose the excellent performance of the battery. − …”

Fundamentals and Scientific Challenges in Structural Design of Cathode Materials for Zinc‐Ion Hybrid Supercapacitors

“…[ 127 ] As a result of their tunnel and layered‐type architectures, MnO 2 can provide adequate paths and places for transporting and intercalating a wide range of metal ions, such as Li/Na/K and Zn ions. [ 21 ] MnO 2 is a valuable material that exhibits a range of crystal forms (α, β, γ, δ, and λ) [ 128 ] and is extensively used in all kinds of energy storage devices such as LIBs, [ 129 ] NIB, [ 130 ] KIBs, [ 130a,131 ] ZIB, [ 132 ] SCs, [ 133 ] and other types of energy storage devices. [ 134 ] The MnO 6 octahedral structural unit is joined by shared corners or edges to form network, tunnel, or multilayer structures.…”

A MnOx–graphitic carbon composite from CO2 for sustainable Li-ion battery anodes

“…14,15 On top of that, new battery concepts with added transition metal oxides have attracted major attention as anode materials after the first report by Poizot et al 16 Metal oxides in the composition of anode materials can lead to a higher theoretical capacity (4700 mA h g À1 ) than commercial graphite (372 mA h g À1 ) because of conversion reactions. 17,18 Among the other transition metal oxides, manganese-based oxides have gained significant attention as the multiple valence states of manganese ions and numerous possible crystalline structures can lead to a higher theoretical capacity of up to 1230 mA h g À1 . 18 In addition to this, manganese oxide may exhibit much lower potential than other metal oxides, which are used to gain higher energy density.…”
