Manganese-based materials are considered as one of the most promising cathodes in zinc-ion batteries (ZIBs) for large-scale energy storage applications owing to their cost-effectiveness, natural availability, low toxicity, multivalent states, high operation voltage, and satisfactory capacity. However, intricate mechanisms coupled with unsatisfactory cycling stability hinder commercial applications. Previous reviews have primarily focused on optimization strategies achieving capacity fast reaction kinetics, while overlooking fluctuation lacking a systematic discussion enhance these materials. Thus, this review, manganese-based ZIBs different structures systematically elucidated summarized. Next, ZIBs, including activation, degradation, dynamic evolution whole cycle calendar comprehensively analyzed. Finally, constructive based chemistry one-electron two-electron transfers durable performance proposed.

Vanadium Oxide Cathode Coinserted by Ni²⁺ and NH₄⁺ for High-Performance Aqueous Zinc-Ion Batteries

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(7), P. 8922 - 8929

Published: Feb. 8, 2024

Vanadium-based oxides have garnered significant attention as cathode materials for aqueous zinc-ion batteries (AZIBs) because of their high theoretical capacity and low cost. However, the limited reaction kinetics poor long-term cycle stability hinder widespread application. In this paper, we propose a novel approach by coinserting Ni2+ NH4+ ions into V2O5·3H2O, i.e., NNVO. Structural characterization shows that coinsertion not only extends interlayer spacing V2O5·3H2O but also significantly promotes transport Zn2+ synergistic "pillar" effect NH4+, well increased oxygen vacancies effectively lower energy barrier insertion. As result, AZIBs with an NNVO electrode exhibit 398.1 mAh g–1 (at 1.0 A g–1) good 89.1% retention even after 2000 cycles at 5.0 g–1. At same time, highly competitive density 262.9 Wh kg–1 is delivered 382.9 W kg–1. Considering simple scheme resultant performance, study may provide positive attempt to develop high-performance AZIBs.

Abstract The deposition–dissolution mechanism with a two‐electron transfer reaction endows aqueous Zn–Mn batteries desirable theoretical energy density. However, due to the limited solubility of traditional manganese‐based materials and competitive Mn shuttle behavior, practical performance is unsatisfactory. Herein, by synergistically incorporating novel Mn‐rich 4 N cathode plasma functionalized carbon nanotubes film (PCNT) interlayer, an battery high Mn‐utilization rate energy/power density successfully developed. Specifically, boasts manganese content dissolution activity, thereby offering copious supply 2+ ions for system. PCNT abundant micropore structures functional groups, not only restrains entrapping dissolved but also offers sites, ensuring concentrating on cathodic side maximizing their contribution electrochemical reaction. Consequently, N‐PCNT exhibits low polarization voltage superior (64.8%). Without MnSO additive, achieves ultra‐high 821.9 W h kg −1 remarkable long‐term cycling stability (90% capacity retention over 9000 cycles). delightful results demonstrate application potential open up new avenues rational design advanced batteries.
