Incompatibility of the gel polymer electrolyte (GPE) and electrode interface due to polarity differences is a key scientific issue in quasi-solid-state lithium-sulfur batteries, and a strong cathode-electrolyte interface can be constructed by modulating the polarity. Abstract Gel polymer electrolytes (GPE) have stimulated the enthusiasm to...
NASICON materials have great potential as a cathode material for sodium-ion batteries. Herein, a high entropy NASICON is synthesized to improve the rate capability and ultra-long cyclic performance. This study has great significance in energy storage devices especially to explore advanced cathode materials for SIBs. Abstract Vanadium based...
A green, simple, and scalable direct upcycling strategy is developed to efficiently transform leached FePO4 material toward LiMn0.25Fe0.75PO4, which delivers excellent electrochemical performance. Abstract Lithium-ion batteries (LIBs) with LiFePO4 (LFP) cathode materials have occupied a significant market share in state-of-the-art power storage...
An ordered-mesoporous powder zirconium oxophosphate (ZrOP) is proposed to construct a Li-ion conductive ASEI by brushing ZrOP on metallic Li. The modified thin Li foil anode enables a multilayered pouch cell based on a high-loading NCM811 cathode with stable cycling and reversible capacity over 1 Ah. This modification also takes the positive effect...
This work proposes a precise colloidal co-assembly method that bridges unilamellar MXene with monolayer mesoporous carbon frameworks (MMCFs), forming MXene/MMCF multilayer superlattices. On-chip micro-supercapacitors fabricated from Ti3C2Tx/MMCFs achieve remarkable areal energy density, benefiting from the full utilization of unilamellar MXene enabled...
A novel surface anion-modulated strategy is used to optimize the activity and stability of seawater electrolysis. The excellent OER performance is attributed to the in situ generated MoO4 2− on the surface of electrode, which could modulate and stabilize the catalytic active phase γ-(Ni, Fe)OOH, and effectively optimize the adsorption energy of reactive...
