Monofluorinated acetal electrolyte for high-performance lithium metal batteries.

High degree of fluorination for ether electrolytes has resulted in improved cycling stability of lithium metal batteries due to stable solid electrolyte interphase (SEI) formation and good oxidative stability. However, the sluggish ion transport and environmental concerns of high fluorination degree drive the need to develop less fluorinated structures. Here, we depart from the traditional ether backbone and introduce bis(2-fluoroethoxy)methane (F2DEM), featuring monofluorination of the acetal backbone.

Blood neutrophils, oligoclonal bands and bridging corticosteroids as predictive factors for MOGAD course: Insights from a multicentric Portuguese cohort.

Background: Myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is a heterogeneous entity with either a monophasic or relapsing course. Well-established predictors of relapsing disease are lacking.

Objective: Identifying predictors of relapsing MOGAD, particularly at disease onset.

Capacity recovery by transient voltage pulse in silicon-anode batteries.

In the quest for high-capacity battery electrodes, addressing capacity loss attributed to isolated active materials remains a challenge. We developed an approach to substantially recover the isolated active materials in silicon electrodes and used a voltage pulse to reconnect the isolated lithium-silicon (LiSi) particles back to the conductive network. Using a 5-second pulse, we achieved >30% of capacity recovery in both Li-Si and Si-lithium iron phosphate (Si-LFP) batteries.
