Iridium successfully occupies in the transition-metal (TM) layer of Li 2 MnO 3 through one facile solid–solution method at 650–1050 °C. Both dopant concentration and calcination temperature have large influence on the performance due to the intrinsic microstructure and crystallization.
Lithium metal has been considered one of the most ideal anode materials for batteries due to its ultrahigh theoretical capacity and energy density. However, the unstable SEI layer and the growth of Li dendrites cause poor cycling performance and even safety hazards, which also severely restrict the commercial application of Li metal batteries.
This work verified that indium in the Li-In alloy can effectively protect the lithium anode and provides an idea for the practical application of lithium metal batteries. In recent years, lithium-ion batteries (LIBs) have been widely used in various fields, such as electric vehicles and electronic portable devices , .
Furthermore, the battery with the Li-In electrode exhibits lower overpotentials and polarization during charge and discharge, which is due to the three-dimensional interconnected alloy structure that can facilitate the uniform deposition of lithium and the formation of stable SEI layers.
Lithium-sulfur (Li-S) batteries have also attracted extensive attention due to their high theoretical capacity and energy density. Therefore, the cycling performance of the battery using the alloy electrode and S as the counter electrode (Li-In//S) was tested.
Since their commercialization in the 1990s, lithium-ion batteries (LIBs) have revolutionized the use of power sources for electronic devices and vehicles by providing high energy densities and efficient rechargeability [1, 2, 3].
(5) This is caused by lithium filaments propagating across the solid electrolyte. (4) The potential of the Li + /InLi half reaction is 622 mV above Li + /Li (Figure S5). This high alloying potential is a substantial thermodynamic barrier to lithium metal plating, and therefore, the electrode should be highly resistant to cell shorting.
