Published: Jan. 5, 2025

Rechargeable batteries employing Li metal anodes have gained increasing attention due to their high energy density. Nevertheless, low stability and reversibility of severely impeded practical applications. Designing current collectors (CCs) with reasonable structure composition is an efficient approach stabilizing the anodes. However, in-depth comprehensive understanding about design principles modification strategies CCs for realizing stable still lacking. Herein, a critical review focusing on rational summarized. First, requirements in are elucidated clarify objectives CCs. Then, including lithiophilic site modification, 3D architecture construction, protective layer crystalline plane engineering, as well corresponding highlighted. On this basis, recent progress development discussed. Finally, future directions suggested focus developing operando monitoring technology, designing cells under conditions close commercial This will spur more insightful researches toward advanced CCs, promote commercialization.

Constructing a 5.2 V High-Voltage Electrolyte via TMSB Additive Enables Ultrahigh Rate Performance Graphite-Based Dual-Ion Batteries

Nano Letters, Journal Year: 2025, Volume and Issue: unknown

Published: April 28, 2025

The development of carbon-based dual-ion batteries (DIBs) is essentially limited by the oxidation decomposition electrolyte at high voltage and unsatisfactory stability cathode-electrolyte interface (CEI). Herein, to address these notorious issues, we successfully achieved a high-performance DIB introducing Tris(trimethylsiloxy)boron (TMSB) additive. It effectively regulated solvation structure original 2 M LiPF6-solved EMC electrolyte. As result, it not only weakens coordination between PF6- anion solvent but also suppresses cathode interface. Such regulation facilitates formation stable CEI layer enriched with highly ion-conductive inorganic components. Benefitting from optimized interfacial kinetics, graphite delivers exceptional rate capability, achieving 87.86% capacity retention after 2000 cycles 5.2 V 84.21% 50 C.
