Driving the Performance Enhancement of Lithium-Ion Battery: Anode Material Perspective

Abstract

Electrical energy is one of the key sources supporting civilization, while the power structure dominated by thermal electricity leads to serious environmental problems in the 21st century. To meet the growing device performance demand and climate goals, exploitations exemplified by lithium-ion batteries (LIBs) are being sought. By fully understanding the electrochemical mechanisms and analysing, designing, and testing various electrode materials, LIB becomes one of the accessible power supplies in electric vehicles (EVs), aerospace, and information sciences. Herein, this paper aims at offering a critical overview of the LIB improvement from the anode material perspective. By focusing on three advanced types of anode materials and going over their mechanism, microstructure, and testing results, current challenges, and future potentials of the development of LIB are highlighted, along with scale-up issues. Note that the focus of future study ought to be recognized as detailed mechanism understanding, material selecting and synthesis, and "jumping out of the lab".
