Insights into Cation Migration and Intermixing in Advanced Cathode Materials for Lithium‐Ion Batteries

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: unknown

Published: June 29, 2024

Abstract Cathode materials are the core components of lithium‐ion batteries owing to determination practical voltage and effective energy battery system. However, advanced cathodes have faced challenges related cation migration intermixing. In this review, study summarizes structural failure mechanisms due mixing cathodes, including Ni‐rich Li‐rich layered spinel, olivine, disordered rock‐salt materials. This review starts by discussing degradation caused intermixing in different focusing on electronic structure, crystal electrode structure. Furthermore, optimization strategies for inhibition rational utilization systematically encapsulated. Last but not least, remaining proposed perspectives highlighted future development cathodes. The accurate analysis using characterization, precise control material synthesis, multi‐dimensional synergistic modification will be key research areas provides a comprehensive understanding emerge as pivotal controllable factors further

Precisely succinonitrile-functionalized PEO electrolytes toward room-temperature all-solid-state lithium batteries

Science China Materials, Journal Year: 2024, Volume and Issue: 67(5), P. 1412 - 1421

Published: March 20, 2024

Polyethylene oxide) (PEO) polymer electrolytes have the potential for use in all-solid-state lithium-metal batteries (ASSLMBs). However, no effective rules been proposed to prepare PEO that overcome limitation being unusable at room temperature. In this study, based on C–H functionalization strategy, we design a highly ion-conductive electrolyte by directly covalently linking succinonitrile functional-groups with lithium coordination activity chains. The enhance disorder and mobility of chains while acting as sites fast ionic-conduction interchain, thus achieving dual optimization free volume around ions migration behavior. Due precise tuning functional-groups, functionalized exhibits enhanced ionic conductivity (>102 times), high transference number (~0.51) wide electrochemical window (~0.47 V). particular, PEO300k (1.01×10−4 S cm−1 25°C) enables stable operation temperature, providing path development polymer-based practical applications.
