Distinctive insights into the stabilities of the LiNi_1−x–yMn_xCo_yO₂ (NMC) cathode family on the basis of the degrees of delithiation are reported. It is revealed that NMC cathodes with higher Ni content may suggest better overall stabilities under an identical degree of delithiation, which contrasts with the common belief that NMC cathodes with higher Ni contents have inherently reduced stabilities.

A high-entropy Prussian blue analogue, Na_x(FeMnNiCuCo)[Fe(CN)₆], is developed as a robust host structure for reversible sodium insertion. Battery cells using the new cathode active material show significantly improved cycling performance and stability, among others due to its nearly zero-strain operation.

A 0D–2D heterostructure electrocatalyst from metal–organic framework and MXene is proposed as a catalytic cathode for lithium–sulfur batteries. The 0D CoZn-Se and 2D N-MXene co-catalysts form double lithiophilic–sulfiphilic binding sites, promote Li ion diffusion, and reduce the energy barrier of Li₂S deposition/dissolution. The catalytic cathode exhibits ultralong cycle life and high area capacity under high sulfur loading and lean electrolyte operation.

A partial sulfuration strategy is developed to fabricate multi-yolk–shell structure for overcoming the barriers of high-capacity anodes. Integrating both the merits of yolk–shell structure for good structural stability and the multiple connection points for fast ion/electron transportation, as-designed composite delivers superior rate capability and long-term cyclability for K/Na/Li-ion storage, outperforming most reported yolk–shell structures and metal-sulfide based anodes.

S-decorated porous Ti₃C₂ MXene is used as effective selenium host, giving high capacity, rate capability, and long lifespan of Na─Se battery. The S-decorated interfaces combined with in situ forming Cu₂Se facilitate the immobilization and transformation of polyselenides and thus lead to efficient surface-dominated capacitive behavior.

Oxygen vacancies-rich MoO_3−x/MXene heterostructure is prepared through hydrazine hydrate reduction and electrostatic assembly, which exhibits superior electrochemical lithium-ion storage performances such as ultrahigh discharge capacity (1258 mAh/g at 0.1 A/g) and outstanding rate capability (474 mAh/g at 10 A/g), benefitting from the introduction of oxygen vacancies and MXene nanosheets.

A dual-halogen solid electrolyte Li₃InCl_4.8F_1.2 is developed with excellent electrochemical stability, which is contributed by F-containing interphases. Li₃InCl_4.8F_1.2 exhibits great potential for high-voltage all-solid-state lithium-ion batteries.

The development of a well-balanced lithium-ion capacitor (LIC) in terms of energy, power, cycle-life, and cost is not trivial at all. In view of the fast-growing research community focusing on the area, this work aims to serve as a guideline for proper LIC design and assembly, as well as for a correct electrochemical characterization and reporting.

The role of Li doping on the performance of Na_0.67Mn_0.6Ni_0.2Li_0.2O₂ cathode material for Na-ion batteries is investigated by solid-state NMR, Operando X-ray diffraction, and density functional theory. The Li dopant reversibly migrates between transition metal and sodium layers and suppresses structural phase transitions upon de/sodiation.

In this review, the applications of 3D printing techniques on different micro electrochemical energy storage devices such as micro-batteries, micro-supercapacitors, and metal ion hybrid micro-supercapacitors are reviewed. The process includes printing components (electrodes, current collectors, substrates, electrolytes, separators, and packages) with arbitrary shapes, fully printed devices with various configurations, and their integration for practical use.

A trifunctional sodium alginate/polyethylene oxide (SA/PEO) binder is proposed for glucose-derived carbon anode, exhibiting excellent sodium storage properties. The initial Coulombic efficiency and capacity of the carbon anode using SA/PEO binder are 10% and 80 mAh g⁻¹ higher than that of poly(vinylidene fluoride) (PVDF) binder, respectively, owing to synergic effects of extra Na⁺ sources, rich Na⁺ channels, and stable H-bonds.

N, O-codoped vertical carbon nanosheet array is constructed on Cu foil (NOCA@Cu) as an efficient Li host through PI self-assembly and subsequent carbonization. Experiments and simulations indicate that 3D NOCA@Cu can confine Li plating in vertical porous channels and homogenize ion concentration and electrical field distributions throughout 3D electrode, leading to uniform Li deposition with high Coulombic efficiency and long cycle life.
