Recent developments in advanced anode materials for lithium-ion batteries

Abstract

The rapid expansion of electric vehicles and mobile electronic devices is the main driver for the improvement of advanced high-performance lithium-ion batteries (LIBs). The electrochemical performance of LIB depends on the specific capacity, rate performance and cycle stability of the electrode material. In terms of the enhancement of LIB performance, the improvement of anode material is also significant compared with cathode material. There are still some challenges in producing an industrial anode material that is superior to commercial graphite. Based on the different electrochemical reaction mechanisms of anode materials for LIBs during charge and discharge, the advantages/disadvantages and electrochemical reaction mechanisms of intercalation-type anode materials, conversion-type anode materials and alloying-type anode materials are summarized in detail. The methods and strategies for improving electrochemical performance of different types of anode materials are emphatically described. Finally, the challenges to the future development of LIBs will be considered. This review can offer meaningful reference value for the construction and performance optimization of anode materials for LIBs.

Lead-Free Double Perovskite Cs2NaErCl6: Li+ as High-Stability Anodes for Li-Ion Batteries

“…The negative electrode is an indispensable part, and the current commercial lithium-ion battery negative electrode materials are based on carbon, Li 4 Ti 5 O 12 , and silicon carbon. However, some problems still exist for such batteries, mainly including low capacity and poor cycle stability. − Therefore, it is urgent to seek new safe and stable battery anode materials for improved performance.…”

Insights into the electrochemical performance of metal fluoride cathodes for lithium batteries

“…Graphene and reduced graphene oxide (RGO) stand out among carbon-based materials due to their outstanding mechanical properties and electrical conductivity [91][92][93][94][95] . Therefore, graphene sheets may be preferred conductive networks and building units to deliver facile electron pathways.…”

In Situ Construction of a Multifunctional Interface Regulator with Amino-Modified Conjugated Diene toward High-Rate and Long-Cycle Silicon Anodes

“…Compared with traditional graphite electrodes, silicon (Si) is deemed to be one of the promising negative electrode materials for lithium-ion batteries (LIBs) because of its ultra-high specific capacity. − Nevertheless, as a semiconductor material, the electronic conductivity of Si material is only 10 –3 S cm –1 , which is much lower than that of graphite (10 4 S cm –1 ). Therefore, the amount of conductive additives in Si anodes is usually 5 times more than that of graphite electrodes. , In addition, the Si electrode is accompanied by a huge volume change (∼400%) during the electrochemical processes, which leads to undesirable electrolyte decomposition reactions to form thick solid electrolyte interface (SEI) films, ultimately leading to a rapid capacity attenuation. − …”
