Fast method for assessing binder migration in lithium-ion battery electrodes using glow discharge-sector field-mass spectrometry

Communications Chemistry
A high amount of energy needed for the production of lithium-ion batteries is used for the drying and solvent recovery of N-methyl-2-pyrrolidone (NMP) in electrodes with polyvinylidene fluoride-based binder (PVdF) systems.

Study on the electrical-thermal properties of lithium-ion battery materials in the NCM622/graphite system

Frontiers in Chemistry
The phenomenon of fire or even explosion caused by thermal runaway of lithium-ion power batteries poses a serious threat to the safety of electric vehicles. An in-depth study of the core-material thermal runaway reaction mechanism and reaction chain is a

Memory and Resting‐State Connectivity in Acute Transient Global Amnesia: A Case–Control fMRI Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Transient global amnesia (TGA) is a striking model of isolated amnesia. While hippocampal lesions are well described, the network‐level mechanisms and the precise neuropsychological profile remain debated. Our objective was thus to characterize functional and neuropsychological correlates of acute TGA and their ...

Evaluation of Digital Technologies for Home‐Based Assessment in People With Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Digital technologies hold promise for transforming healthcare by enhancing personalized treatments and offer valuable opportunities to improve patient care. Here, we evaluated several novel, self‐administered, home‐based, digital endpoints for their association with corresponding conventional standard clinical measures (primary) in ...

Aqueous Processing of Ni‐Rich Layered Oxides: Impact of Native Surface Layer on Crystal Water and Feasible Sulfate‐Based Processing Additive Strategies

Advanced Energy & Sustainability Research
Aqueous processing of conventional Ni‐rich layered oxide cathodes (here LiNi0.83Co0.12Mn0.05O2, NCM) can be a sustainable alternative to conventional organic solvent‐based processing. However, the LiOH‐based native surface layer of NCM dissolves in water
