Extra Storage Capacity Enabled by Structural Defects in Pseudocapacitive NbN Monocrystals for High-Energy Hybrid Supercapacitors

Shaowen Zhou et al.

Summary: Li-ion hybrid supercapacitors with high power densities are intensively studied, and this study introduces a defect-dominating structure protocol to improve the energy density of the anode material. By introducing crystal vacancies and lattice distortions in the ultrafine niobium nitride monocrystals integrated into a carbon framework, a NbN@C composite anode is created with high reversible Li-ion storage capacities, excellent rate capability, and cycling stability. First-principles density functional theory simulations confirm the extra capacity contribution of the defective NbN component. The findings from this study can inspire new structural material designs of LHSCs.

Extra storage capacity in transition metal oxide lithium-ion batteries revealed by in situ magnetometry

Qiang Li et al.

Summary: Although some transition metal oxide-based electrodes exhibit high storage capacities beyond theoretical values, the surface capacitance on metal nanoparticles involving spin-polarized electrons is consistent with a space charge mechanism. The phenomenon of anomalously high storage capacities in different metal oxides is still under debate, but in situ magnetometry has shown that surface capacitance plays a dominant role in providing extra capacity. This space charge mechanism can be generalized to a broad range of transition metal compounds, providing guidance for advanced energy storage systems.

Reacquainting the Electrochemical Conversion Mechanism of FeS2 Sodium-Ion Batteries by Operando Magnetometry

Zhaohui Li et al.

Summary: This study investigates the effect of ion-embedding mechanisms on the electrochemical properties of FeS2/Na (Li) cells through a combination of operando magnetometry and electrochemical measurements. It is found that the smaller iron grains produced by the conversion reaction in SIBs lead to more serious pulverization and worse cycle performance. The sluggish kinetics in SIBs caused by the larger Na-ion radius is identified as the underlying reason for the observed phenomena.
