The unstable electrode/electrolyte interface of high-capacity LiNi0.8Co0.15Al0.05O2 (NCA) cathodes, especially at a highly delithiated state, usually leads to the transformation layered spinel and/or rock-salt phases, resulting in drastic capacity fade and poor thermal stability. Herein, Al-increased Ni-,Co-decreased electrode surface is fabricated through tailoring element distribution micrometer-sized spherical NCA secondary particles via coprecipitation solid-state reactions, aimed...

Hierarchical nanostructures with outstanding electrochemical properties and mechanical stability are ideal for constructing flexible hybrid supercapacitors. Herein, hierarchically hollow NiCo2S4@NiS were designed synthesized by sulfurizing the hierarchical NiCo double hydroxides (DHs) coated nickel hydroxide on carbon fabrics (NiCo-DHs@Ni(OH)2/CF), which trigger excellent performances. The NiCo2S4@NiS/CF exhibits a high specific capacity of 1314.0 C g-1 at current density 1 A g-1, maintains...

Abstract Inactive elemental doping is commonly used to improve the structural stability of high-voltage layered transition-metal oxide cathodes. However, one-step co-doping strategy usually results in small grain size since low diffusivity ions such as Ti 4+ will be concentrated on boundaries, which hinders growth. In order synthesize large single-crystal cathodes, considering different diffusivities dopant ions, we propose a simple two-step multi-element fabricate core–shell structured...

Abstract Sodium‐ion batteries (SIBs) offer excellent potential for meeting the urgent need to develop low‐cost and durable large‐scale electrical energy storage systems. However, electrochemical performance of currently available SIBs requires substantial improvement enable their practical deployment. The cathode material is one greatest factors impacting SIB performance. recent development cathodes with core–shell structures concentration gradients offers considerable promise addressing...

To improve the Li+ kinetics and structural stability of high-capacity nickel-rich layered oxides, but not at cost reducing reversible capacity, a heterogeneous inactive-Al3+ doping strategy is proposed to build an Al3+-rich surface within low amount. As anticipated, doped LiNi0.7Co0.15Mn0.15O2 shows large capacity ∼215 mAh g–1, corresponding high energy density ∼850 Wh kg–1. Moreover, it also exhibits long-term cycle lifespan, retention ∼90% after 200 cycles even upper cutoff voltage 4.5 V...
