Abstract Considering the natural abundance and low cost of sodium resources, sodium‐ion batteries (SIBs) have received much attention for large‐scale electrochemical energy storage. However, smart structure design strategies good mechanistic understanding are required to enable advanced SIBs with high density. In recent years, exploration cathode, anode, electrolyte materials, as well diagnostics been extensively carried out. This review mainly focuses on challenging problems attractive...
Abstract Nickel‐rich layered lithium transition metal oxides (LiNi 1− x − y Co Mn O 2 and LiNi Al , + ≤ 0.2) are the most attractive cathode materials for next generation lithium‐ion batteries automotive application. However, they suffer from structural/interfacial instability during repeated charge/discharge, resulting in severe performance degradation serious safety concerns. This work provides a comprehensive review about challenges strategies to advance nickel‐rich cathodes specifically...
Perspective on recent improvements in experiment and theory towards realizing lithium metal electrodes with liquid electrolytes.
From dictating the redox potential of electrolyte solvents to shaping stability solid-electrolyte interfaces, solvation plays a critical role in electrochemistry electrolytes.
We reported the interplay between phase structures, interfacial microstrain and electrochemical properties of layered cathodes.
A lithium-air battery based on lithium oxide (Li2O) formation can theoretically deliver an energy density that is comparable to of gasoline. Lithium involves a four-electron reaction more difficult achieve than the one- and two-electron processes result in superoxide (LiO2) peroxide (Li2O2), respectively. By using composite polymer electrolyte Li10GeP2S12 nanoparticles embedded modified polyethylene matrix, we found Li2O main product room temperature solid-state battery. The rechargeable for...
Transitioning from polycrystalline to single-crystalline nickel-rich cathodes has garnered considerable attention in both academia and industry, driven by advantages of high tap density enhanced mechanical properties. However, with nickel content (>70%) suffer substantial capacity degradation, which poses a challenge their commercial viability. Leveraging multiscale spatial resolution diffraction imaging techniques, we observe that lattice rotations occur universally play pivotal role the...
In the search for a transformative new energy storage system, rechargeable Li/sulfur battery is considered as one of promising candidates due to its much higher density and lower cost than state-of-the-art lithium-ion batteries. However, insulating nature sulfur dissolution intermediary polysulfides into electrolyte significantly hinder practical application.

Relative solvating power, that is, the ratio of coordination ratios between a solvent and reference solvent, was used to probe quantitative structure-activity relationship electrolyte solvents lithium polysulfide (LiPS) dissolution in lithium-sulfur batteries. Internally referenced diffusion-ordered nuclear magnetic resonance spectroscopy (IR-DOSY) determine diffusion coefficient ratio, from which relative power can be easily measured. The higher an ethereal more severe will LiPS lower...

In this review, challenges and strategies to enable the use of micro-sized alloy anodes for alkali-ion batteries with high energy density long cycle life are explored.
Abstract Lithium/selenium‐sulfur batteries have recently received considerable attention due to their relatively high specific capacities and electronic conductivity. Different from the traditional encapsulation strategy for suppressing shuttle effect, an alternative approach directly bypass polysulfide/polyselenide formation via rational solid‐electrolyte interphase (SEI) design is demonstrated. It found that robust SEI layer in situ forms during charge/discharge interplay between cathode...
