Published: April 7, 2024

Abstract Composite polymer solid electrolytes (CPEs), possessing good rigid flexible, are expected to be used in solid‐state lithium‐metal batteries. The integration of fillers into matrices emerges as a dominant strategy improve Li + transport and form ‐conducting electrode–electrolyte interface. However, challenges arise traditional fillers: 1) inorganic fillers, characterized by high interfacial energy, induce agglomeration; 2) organic with elevated crystallinity, impede intrinsic ionic conductivity, both severely hindering migration. Here, concept super‐ionic conductor soft filler, utilizing conductivity nanocellulose (Li‐NC) model, is introduced which exhibits conductivity. Li‐NC anchors anions, enhances speed, assists the cathode–electrolyte electrodes for room temperature tough dual‐channel electrolyte (TDCT) polyvinylidene fluoride (PVDF) demonstrates transfer number (0.79) due synergistic coordination mechanism transport. Integrated electrodes’ design enables stable performance LiNi 0.5 Co 0.2 Mn 0.3 O 2 |Li cells, 720 cycles at C, 88.8% capacity retention.

An Ultra-Stable, High-Energy and Wide-Temperature-Range Aqueous Alkaline Sodium-Ion Battery with the Microporous C4N/rGO Anode

Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: Feb. 24, 2025

Abstract Common anode materials in aqueous alkaline electrolytes, such as cadmium, metal hydrides and zinc, usually suffer from remarkable biotoxicity, high cost, serious side reactions. To overcome these problems, we develop a conjugated porous polymer (CPP) in-situ grown on reduced graphene oxide (rGO) Ketjen black (KB), noted C 4 N/rGO N/KB respectively, the alternative anodes. The results show that electrode delivers low redox potential (−0.905 V vs. Ag/AgCl), specific capacity (268.8 mAh g −1 at 0.2 A ), ultra-stable fast sodium ion storage behavior (216 20 ) 2 M NaOH electrolyte. assembled N/rGO//Ni(OH) full battery can cycle stably more than 38,000 cycles. Furthermore, by adding small amount of antifreeze additive dimethyl sulfoxide (DMSO) to adjust hydrogen bonding network, low-temperature performance electrolyte (0.1 DMSO/2 NaOH) is significantly improved while evolution inhibited. Consequently, cell exhibits an energy density 147.3 Wh Kg ultra-high cycling stability over wide temperature range −70 45 °C. This work provides high-capacity CPP-based for batteries will facilitate their practical applications under extreme conditions.
