Special Issue Information

Dear Colleagues, 

With the rapid development of materials, fabrication methods, procedures and characterization techniques since its advent a few decades ago, lithium ion batteries (LIBs) have represented the main power source of consumer electronic devices, energy storage systems and electrical vehicles. However, some usage issues still remain, including their poor safety, relatively low energy density and temperature sensitivity. In order to further improve the comprehensive performance of LIBs, several innovative strategies have been attempted, such as elemental doping, nanostructures (nanoparticle, nanotube, nanowire and nanofilm), surface modification, compositing, pretreatment, new binders and new electrolytes and combinations of all. This Special Issue will highlight the following aspects: 1) progress and phenomena related to LIBs, including an in-depth understanding of the dynamical behavior of (de)lithiation of electrode materials and the electrode–electrolyte interface reaction; 2) the development of new materials, including electrolytes, electrodes, current collectors, etc.; 3) the interface optimization of the solid electrolyte–Li metal interface in all solid-state Li metal batteries; and 4) other electrochemical energy storage systems.

The development of a current collector for Li-ion batteries is of great significance for improving the performance of Li-ion batteries. Tensile property and corrosion performance of the positive electrode current collectors are an indispensable prerequisite for the realization of high-performance Li-ion batteries. In our study, the effects of Ag alloying on the microscopic structure, electrical conductivity, tensile property and corrosion resistance of Al-xCu (x = 0.1–0.15%) alloy foils were investigated. Moderate Ag addition on the Al-Cu alloy could reduce the size of second phases and promote the formation of second phases. The tensile strength of the Al-0.1Cu-0.1Ag alloy was higher than that of the Al-0.1Cu alloy at both room and high temperatures. All of the alloy foils demonstrated high electrical conductivity around 58% ICAS. The corrosion potential and corrosion current density of the Al-0.1Cu alloy were demonstrated by Tafel polarization to be −873 mV and 37.12 μA/cm2, respectively. However, the Al-0.1Cu-0.1Ag alloy showed enhanced corrosion resistance after the Ag element was added to the Al-0.1Cu alloy, and the Al-0.1Cu-0.1Ag alloy had a greater positive corrosion potential of −721 mV and a lower corrosion current density of 1.52 μA/cm2, which suggests that the Ag element could significantly improve the corrosion resistance of the Al-Cu alloy.
