Highly textured and crystalline materials for rechargeable Li‐ion batteries

Abstract

To build an environment-friendly energy-based society, it is important to develop stable and high-performance batteries as an energy storage system. However, there are still unresolved challenges associated with safety issues, slow kinetics, and lifetime. To overcome these problems, it is essential to understand the battery systems including cathode, electrolyte, and anode. Using a well-controlled material system such as epitaxial films, textured films, and single crystals can be a powerful strategy to investigate the relationship between microstructural and electrochemical properties. In this review, we discuss the need for research with wellcontrolled materials system and recent progress in the well-controlled cathode, solid-state-electrolyte, and anode materials for Li-ion batteries. Enhanced stability and electrochemical performance due to the facilitation of prolonged and endured Li-ion transport in facet-controlled battery materials are highlighted. Finally, the challenges and future directions utilizing the well-controlled battery system for high-performance battery are proposed.

A Novel and Convenient Sol‐Gel Approach for the Synthesis of High‐Performance LiNi1/3Co1/3Mn1/3O2 Cathode Materials in Lithium‐Ion Batteries

“…[8,9] The cathode material is a critical factor in determining the energy density, cycle life, and safety of LIBs. [10][11][12] Currently, commercially available cathode materials for LIBs include olivine-structured transition metal phosphate (LiFePO 4 ) and layered transition metal oxides such as LiCoO 2 , LiNiO 2 , LiMnO 2 . [13] Although LiFePO 4 is an economical, non-toxic, and stable material with excellent cycling and safety performance, its low specific capacity, poor conductivity, and battery short-circuit issues limit its universal use.…”
