Surface and Interface Engineering of Electrode Materials for Lithium‐Ion Batteries

Abstract

Lithium-ion batteries are regarded as promising energy storage devices for next-generation electric and hybrid electric vehicles. In order to meet the demands of electric vehicles, considerable efforts have been devoted to the development of advanced electrode materials for lithium-ion batteries with high energy and power densities. Although significant progress has been recently made in the development of novel electrode materials, some critical issues comprising low electronic conductivity, low ionic diffusion efficiency, and large structural variation have to be addressed before the practical application of these materials. Surface and interface engineering is essential to improve the electrochemical performance of electrode materials for lithium-ion batteries. This article reviews the recent progress in surface and interface engineering of electrode materials including the increase in contact interface by decreasing the particle size or introducing porous or hierarchical structures and surface modification or functionalization by metal nanoparticles, metal oxides, carbon materials, polymers, and other ionic and electronic conductive species.

Chemically Integrated Multiwalled Carbon Nanotubes/Zinc Manganate Nanocrystals as Ultralong-Life Anode Materials for Lithium-Ion Batteries

“…11 Unfortunately, these single metal oxides undergo large volume changes during the charging and discharging processes, leading to the deterioration of capacity and rate capability. 12,13 It is interesting to note that mixed transition-metal oxides (MTMOs) in spinel structure, such as AB 2 17,18 etc. ), have exhibited good electrochemical properties as anode materials owing to their higher electrical conductivity and lager specific capacity than that of TMOs.…”

Atomic layer deposition derived amorphous TiO2 thin film decorating graphene nanosheets with superior rate capability

“…In particular, the lithium ion motion across the interface and/or within the TiO 2 anode is slow for the charge distribution to obtain equilibrium at high specific current. Thus, with the increase of specific currents, the reversible capacity of the TiO 2 anode decreases [26,27].…”

Recent Progress in Self‐Supported Metal Oxide Nanoarray Electrodes for Advanced Lithium‐Ion Batteries

“…Hierarchical structures comprising nanoscale building blocks show promising prospects for LIB electrode materials because small particle size, high specific surface area, and other structural features including accessible porous systems and large void spaces can be readily introduced to a hierarchical structure through self‐assembly of nanoscale subunits 83. Herein, hierarchical nanoarrays refer to aligned arrays of hierarchical 1D and 2D nanostructures (e.g., nanorods, nanobelts, nanotubes, nanosheets, nanoplates, and nanowalls) consisting of nanoscale building blocks.…”
