Asymmetric Kinetics Inducing Anion-Intercalation Overpotential Growth at the Cathode Governs Capacity Fading in Dual-Ion Batteries

P2/O3 Biphasic Layered Oxide Cathodes Induced by Dual-Site Doping for Durable Sodium-Ion Batteries

The practical application of layered oxide cathodes in sodium-ion batteries is severely hindered by structure collapse and interfacial degradation during prolonged cycling, which originate primarily from irreversible phase transition and...

Visualizing Degradation in Anode-Free High-Capacity Aqueous Tin Metal Batteries Across Cell Lifetime

Anode-free cell configurations represent one of the highest energy density battery architectures. In aqueous batteries, electrodeposition is often limited by dendritic growth and parasitic co-evolution of hydrogen gas. The aqueous...

Evaluating the performance and practical viability of Glyme-Based Electrolytes for anode-free Na-cells

Anode-free sodium metal batteries (AFSMBs), as a potential strategy for achieving high energy density, have garnered considerable interest recently due to their demonstrated stable cycling performance when paired with ether-...

Electrolytes that mind bridging the gap

Nitrogen-Doped Hierarchical Carbon Architectures Coupled with MoSe 2 for High-Voltage Lithium-Ion Capacitors

The practical performance of lithium-ion capacitors (LICs) is frequently limited by the imbalance in capacity, reaction kinetics, and operating potential between battery-type anodes and capacitive cathodes. Here, a common polyimide...

High-voltage and Long-life Mg-ion Storage in Layered Molybdenum Oxide with Structural Regulation

Rechargeable magnesium-ion batteries (MIBs) have attracted widespread attention on account of their excellent theoretical volumetric capacities, dendrite-free feature and cost-effectiveness of Mg metal anodes. However, MIB electrolytes are unstable under...
