Fast Charging Anode Materials for Lithium‐Ion Batteries: Current Status and Perspectives

Abstract

With the enormous development of the electric vehicle market, fast charging battery technology is highly required. However, the slow kinetics and lithium plating under fast charging condition of traditional graphite anode hinder the fast charging capability of lithium‐ion batteries. To develop anode materials with rapid Li‐ions diffusion capability and fast reaction kinetics has received widely attentions. This review summarizes the current status in the exploration of fast charging anode materials, mainly including the critical challenge of achieving fast charging capability, the inherent structures and lithium storage mechanisms of various anode materials, as well as the recent progress to improve the rate performance involving morphology regulation, structure design, surface/interface modification, as well as forming multiphase systems. Finally, the challenges and future directions of developing fast charging Li‐ion batteries are highlighted.

Ultrasonication-assisted fabrication of porous ZnO@C nanoplates for lithium-ion batteries

“…The increase of R 1 for the ZnO@C electrodes after cycling was negligible. Furthermore, after 100 cycles, the ZnO@C composite electrode possessed a much lower interfacial resistance (4.64 Ω) than that of ZnO (44.6 Ω), and an obviously smaller charge transfer resistance of 48.54 Ω for ZnO@C and 216.3 Ω for ZnO, indicating that the ZnO@C composite-based electrode exhibited faster charge transfer [46] . EIS spectra were also applied to compare the lithium diffusion coefficient of two materials with the details described in the supporting information [Supplementary Figure 12].…”

Charge storage mechanisms of a π–d conjugated polymer for advanced alkali-ion battery anodes

“…Development of fast-charging metal-ion batteries is crucial for solving the "range anxiety" issue of electric vehicles that impedes their mass-market adoption. [1][2][3] Unfortunately, conventional graphite anodes are unsuitable for fast charging because of hazardous dendrite formation at low potentials. [4][5][6] High-rate capabilities can be enabled with anode materials operating in safe potential ranges ($0.5-2.0 V vs. Li + /Li).…”

A two-dimensional metallic SnB monolayer as an anode material for non-lithium-ion batteries

“…Lithium-ion batteries (LIBs) are widely used in electronic products, energy storage systems, aerospace and other fields due to their high energy density, recyclability, highest output voltage and excellent rate performance. [1][2][3] However, further development of LIBs faces many challenges, such as the lack of lithium metal resources, dendritic growth and capacity attenuation. [4][5][6] In contrast, Na-, K-and Mg-ion batteries have the advantages of low cost, natural abundance and good ion conductivity.…”
