1. Introduction. Lithium-ion batteries (LiBs) dominate energy storage devices due to their high energy density, high power, long cycling life and reliability [[1], [2], [3]].With continuous increasing of energy density and decreasing in manufacturing cost, LiBs are progressively getting more widespread applications, especially in electric vehicles …
Magnesium-based rechargeable batteries might be an interesting future alternative to lithium-based batteries. Here the available results of research, both on rechargeable negative electrodes based either on metallic magnesium or alternative materials, and on materials suitable as positive, magnesium-inserting …
As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials. In this …
Using high voltage LiCoO 2 as a worst case scenario, the negative electrode would need to rise to 0.9 V for the full cell potential to reach the 3.0 V cutoff. …

Nickel nitride has been prepared through different routes involving ammonolysis of different precursors (Ni(NH3)6Br2 or nickel nanoparticles obtained from the reduction of nickel nitrate with hydrazine) and thermal decomposition of nickel amide obtained by precipitation in liquid ammonia. The electrochemical
For a Li-ion battery this implies that the electrode material of interest is used as a working electrode, while metallic lithium is used as both the counter and reference electrode simultaneously. Although lithium metal is a non-ideal reference electrode, this simplified configuration has worked reasonably well.
As indicated in Figure 4.1, the potential lithium insertion (∼0.2 V) into negative electrode (graphite) is located below the electrolyte LUMO (which is for organic, carbonate electrolyte at ∼1.1 eV). This means that the electrolyte undergoes a reductive decomposition with formation of a solid electrolyte interphase (SEI) layer at potential …

In addition, due to lithium electroplating, the pores of the negative electrode material are blocked and the internal resistance increases, which severely limits the transmission of lithium ions, and the generation of lithium dendrites can cause short circuits in the battery and cause TR [224]. Therefore, experiments and simulations on the ...
