However, accompanied by the fire accident of various phones, lithium metal as a negative electrode material officially withdrew from the markedr. Since then, people''s research has shifted to the use of lithium-free anode materials. This article describes the researchers'' efforts in the study of lithium-free anode materials.
The current accomplishment of lithium-ion battery (LIB) technology is realized with an employment of intercalation-type electrode materials, for example, graphite for anodes and lithium transition ...

This paper illustrates the performance assessment and design of Li-ion batteries mostly used in portable devices. This work is mainly focused on the selection of negative electrode materials, type of electrolyte, and selection of …
The lithium detected on the negative electrode surface is partly from the lithium salt in the negative electrode interface film and partly from the negative layer structure. Since the battery in this work is disassembled in a fully discharged state, the negative electrode of the battery should be in a completely delithiated state.
Abstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau. However, a significant increase in volume during the intercalation of lithium into tin leads to degradation and a serious …
The pursuit of new and better battery materials has given rise to numerous studies of the possibilities to use two-dimensional negative electrode materials, such as MXenes, in lithium-ion batteries. …
For nearly two decades, different types of graphitized carbons have been used as the negative electrode in secondary lithium-ion batteries for modern-day energy storage. 1 The advantage of using carbon is due to the ability to intercalate lithium ions at a very low electrode potential, close to that of the metallic lithium electrode (−3.045 V vs. …

Among the lithium-ion battery materials, the negative electrode material is an important part, which can have a great influence on the performance of the overall lithium-ion battery. At present, anode materials are mainly divided into two categories, one is carbon materials for commercial applications, such as natural graphite, soft carbon, …
The electrochemical properties of the electrodes were studied in a sealed three-electrode Teflon cell with a working electrode based on the material under study, a lithium counter electrode, a reference electrode, and an electrolyte based on a 1 M solution of lithium hexafluorophosphate LiPF6 in a mixture of ethylene carbonate and dimethyl ...
