To improve the energy density of Li-ion batteries, conventional sacrificial prelithiation agents (LiFeO, LiO and LiCO, etc.) are introduced to compensate for active lithium loss, but they undergo serious volumetric shrinkage during decomposition, generating voids that compromise electrode architecture integrity and deteriorate electrochemical performance. Herein, the typical Li-rich layered oxide cathode is converted into Li-rich disordered rocksalt oxide (LRDO) prelithiation agent, achieving 330 mAh g charge capacity and retaining 130 mAh g reversible capacity (contributing 200 mAh g irreversible prelithiation capacity).

Efficient hydrogen production through water electrolysis relies on catalytic electrodes with low onset potentials and uniform activity. This study presents an optical polarization imaging technique for real-time, in situ mapping of the activity distribution on catalytic electrode surfaces during the hydrogen evolution reaction (HER) in water electrolysis. By monitoring changes in the degree of polarization (DoP) of the reflected light during bubble formation on the electrode surface, this technique quantitatively analyzes the hydrogen evolution activity.

Traditional characterization techniques for vanadium flow batteries (VFBs) electrodes demonstrate significant limitations in resolving spatially heterogeneous reaction characteristics on electrode surfaces and efficiently characterizing large-scale working electrodes. Consequently, mapping electrode activity distributions and establishing efficient screening strategies for high-performance electrodes are critical for advancing VFBs research. Building on prior studies, this work employs weak measurement imaging (WMi) methodology to spatially characterize reaction activity distributions on VFBs positive electrode surfaces and quantitatively analyze electrode reaction parameters (i and i).

Efforts to improve the specific capacity and energy density of lithium nickel-cobalt-manganese oxide (NCM) cathodes focus on operating at high voltages or increasing nickel content. However, both approaches necessitate a thorough understanding of the charge compensation mechanism. Traditional ionic-bonding models which separate transition metal (TM) and oxygen redox processes prove inadequate as anionic redox becomes significant, ignoring crucial metal-oxygen interactions.

Excessive neutrophil infiltration can exacerbate inflammation and tissue damage, contributing to conditions like autoimmune disorders and liver diseases. Mesenchymal stromal cells (MSCs) share homing mechanisms with neutrophils, showing promise for treating such diseases. However, ex vivo expanded MSCs often suffer from reduced homing efficiency due to the loss of essential ligands.

Extending the depth-of-charge (DoC) of the layered oxide cathode presents an essential route to improve the competitiveness of the Na-ion battery versus the commercialized LiFePO-based Li-ion battery (0.8 CNY/Wh). However, the DoC-dependent boundary between detrimental/irreversible structural distortion and neutral/reversible structure interconversion cannot be clearly distinguished, which is attributed to the ambiguous recognition of correlation among the complex phase transition, local covalent environment evolution, and charge compensation.
