Modification Strategies of High-Energy Li-Rich Mn-Based Cathodes for Li-Ion Batteries: A Review

Molecules, Journal Year: 2024, Volume and Issue: 29(5), P. 1064 - 1064

Published: Feb. 29, 2024

Li-rich manganese-based oxide (LRMO) cathode materials are considered to be one of the most promising candidates for next-generation lithium-ion batteries (LIBs) because their high specific capacity (250 mAh g−1) and low cost. However, inevitable irreversible structural transformation during cycling leads large loss, poor rate performance, energy decay, voltage etc. Based on recent research into LRMO LIBs, this review highlights progress in terms crystal structure, charging/discharging mechanism investigations, prospects solution current key problems. Meanwhile, summarizes modification strategies merits demerits, i.e., surface coating, elemental doping, micro/nano design, introduction entropy, Further, future development trend business prospect presented discussed, which may inspire researchers create more opportunities new ideas LIBs with density an extended lifespan.

High-throughput screening of phosphide compounds for potassium-ion conductive cathode application

Journal of Materials Informatics, Journal Year: 2025, Volume and Issue: 5(2)

Published: March 11, 2025

Cathode materials are crucial in potassium (K) batteries, directly impacting their performance and lifespan. In this study, we used a combination of geometrical-topological (GT) analysis, bond valence site energy (BVSE), Kinetic Monte Carlo (KMC), first-principles calculations to screen potential cathode for K-ion batteries among inorganic phosphides. Through GT screened 143 K- P-containing compounds identified 30 with two- or three-dimensional migration pathways. BVSE further narrowed down 13 energies below 1 eV. KMC simulations ionic conductivity led the selection K3Cu3P2 detailed calculations. It was demonstrated that possesses reversible capacity 72.47 mAh·g-1, minimal volume change (1.47%), charge compensation mechanism involving Cu P. Its low barrier contributes high diffusion coefficient 1.87 × 10-3 S·cm-1 at 25 °C, making promising candidate stable efficient applications.

In Situ/Operando Spectroscopic Techniques for Nonaqueous Lithium-Based Batteries

The Journal of Physical Chemistry C, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 25, 2024

Nonaqueous lithium-based batteries have become a dominating stream of modern energy storage systems. Understanding the physicochemical processes and mechanisms electrode evolution interfacial reactions in lithium is highly desired to further improve their capabilities. Compared with ex situ testing techniques, situ/operando spectroscopic techniques are significant importance battery research because they can provide more dynamic transient information under working conditions. Herein, this review we systematically introduce various for development nonaqueous Li batteries, including infrared (IR) spectroscopy, Raman scattering (Raman) nuclear magnetic resonance (NMR) sum frequency generation vibrational spectroscopy (SFG-VS) X-ray absorption (XAS). The recent advances these especially applications studying materials electrode–electrolyte interphases, been comprehensively summarized. Finally, propose future potential research.
