Abstract Sodium‐ion batteries (NIBs) have become an ideal alternative to lithium‐ion in the field of electrochemical energy storage due their abundant raw materials and cost‐effectiveness. With progress human society, requirements for systems extreme environments, such as deep‐sea exploration, aerospace missions, tunnel operations, more stringent. The comprehensive performance NIBs at low temperatures (LTs) has also important consideration. Under LT conditions, challenges increased viscosity...
The synthesis of novel Co doped Zn<sub>2</sub>GeO<sub>4</sub> hollow micro-spheres and the enhanced electrochemical performance for lithium-ion batteries.
The O3-type layered oxide represents a highly promising candidate for sodium-ion batteries (SIBs). However, the intrinsic stability law of these cathodes remains elusive due to complex phase transition mechanism and migration metal (TM) ions. Here, we underscore how ratio between spacings alkali layer TM (R = dO-Na-O/dO-TM-O) plays critical role in determining structural corresponding electrochemical performance. We design peculiar family NaxMn0.4Ni0.3Fe0.15Li0.1Ti0.05O2 (0.55 ≤ x 1)...
Low-cost sodium-ion batteries have demonstrated great prospects in energy storage, among which layered transition metal oxides hold potential as a cathode material. However, the notorious phase materials has greatly hampered their cycle life due to large volume changes upon desodiation/sodiation. In this study, by adopting an O3-type NaNi1/3Fe1/3Mn1/3O2 (NFM) with controlled synthesis temperatures, we revealed that grain size is closely related its behaviors. The material smaller and more...
We demonstrate a facile fabrication in which encapsulation of GeO<sub>x</sub> nanoparticles into hollow carbon shells is achieved through co-axial electrospinning. The resultant GeO<sub>x</sub>@C core–shell fiber electrode exhibits excellent lithium storage performance, with stable reversible capacity and rate capability.

Layered P2-type sodium manganese oxide has emerged as a promising cathode candidate for sodium-ion batteries due to its appealing cost-effectiveness and high discharge voltage. However, practical capacity within the voltage range of 2.0–4.0 V (vs Na+/Na) is relatively low, rate capability hampered by adverse charge/vacancy ordering during charge/discharge. In this study, layered P′2/P3 mixed-phase Na0.8-aMn0.675Ni0.225Li0.1O2–x with (003) crystal plane intensity was designed introducing...
The difference in cationic potentials of the various elements and between transition metal layers is another essential factor to be taken into account discriminate P/O types layered materials.
Intercalation-type metal oxides are promising active anode materials for the fabrication of safer rechargeable lithium-ion batteries, as they capable minimizing or even eliminating Li plating at low voltages. Due to excellent cycle performance, high specific capacity and appropriate working potential, TiNb2O7 (TNO) is considered be candidate materials. Despite a lot beneficial characteristics, slow electrochemical kinetics TNO-based anodes limits their wide use. In this paper, TiNb2O7@C was...
One-dimensional (1D) Co 9 S 8 /Co(OH)F heterostructures were constructed by in situ sulfidation of Co(OH)F nanobelts to improve the electrocatalytic activity oxygen evolution.
Electric vehicles and energy storage will become the main application fields of next generation lithium-ion batteries, which require excellent performances such as high safety, large capacity power density for batteries. However, currently single cathode materials LiCoO 2 、LiMn O 4 、LiFePO 、LiCo 1/3 Ni Mn ,could not meet these requests at same time. Mixing different structures together is one practical way to improve by complementary advantages each other. This work electronic conductivity...
