Facile modification using organic acid molecules to neutralize residual alkaline compounds for stabilizing LiNi0.95Co0.04Mn0.01O2 cathode material

Energy Materials and Devices
The presence of residual alkaline compounds in the ultrahigh-nickel layered oxide cathodes (LiNixCoyMn1−x−yO2, x ≥ 0.9) aggravates structural degradation, increases surface reactivity, and promotes slurry gelation, leading to the capacity decay of ...

Direct observation of active material concentration gradients and crystallinity breakdown in LiFePO4 electrodes during charge/discharge cycling of lithium batteries

, 2014
The phase changes that occur during discharge of an electrode comprised of LiFePO4, carbon, and PTFE binder have been studied in lithium half cells by using X-ray diffraction measurements in reflection geometry. Differences in the state of charge between

Angstrom‐Scale Confined Ion Sieve and Accelerator for Efficient Aqueous Zinc Batteries

Advanced Materials, EarlyView.
An angstrom‐scale confined ion accelerator strategy is proposed for ultra‐stable aqueous Zn anodes. Selective and precise transport of hydrated Zn(H2O)62+, Zn2+ cations, H2O molecules, and SO42− anions is achieved by in‐plane atomic Ti vacancies and angstrom‐scale interlayer free spacing within the Ti0.87O2 interfacial layer, leading to homogeneous Zn ...

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements

Advanced Materials, EarlyView.
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

Chloride Ions: Essential Agents for Achieving Spontaneous Delamination of MXene

Advanced Materials, EarlyView.
This work first identifies chloride ions as essential agents for spontaneous MXene delamination. Without Cl−, etched Ti3C2Tx remains multilayered; with Cl−, interlayer modification enables Li+ intercalation and osmotic swelling. The SPEED process couples HF‐assisted Al extraction, Cl−‐mediated interlayer expansion, and Li+‐driven swelling to produce ...

Enhancing Semi‐Ionic C–F Bond Ratio of the Carbon Fluoride Cathodes With High Conductivity for Primary Lithium Batteries

ChemElectroChem
For lithium/carbon fluoride (Li/CFX) battery, due to the strong covalent nature of the C–F bond, CFX exhibits very low electronic conductivity and is prone to polarization, resulting in poor rate performance of Li/CFX batteries, which cannot meet high ...
