Ceramic-based dielectric capacitors have gained prominence in research owing to their high relative permittivity, excellent mechanical properties, and temperature stability. BiFeO 3 -based ceramics have captured significant attention in dielectric capacitors attributable to their high saturation polarization. Yet, the high remanent polarization, as well as the low electric breakdown strength, constrains the improvement of their energy storage performances. Herein, we incorporated the A-/B-site complicated component (La 0.5 Na 0.5 )(Mg 1/3 Nb 2/3 )O 3 into the binary solid solution 0.7BiFeO 3 –0.3BaTiO 3 ceramics with morphotropic phase boundary, to enhance the endurance for electric field and reduce remanent polarization by optimizing relaxor behavior. Consequently, a high recoverable energy density of 8.3 J/cm 3 and a high efficiency of 84.6% under 500 kV/cm were obtained in the preferred composition. These results offer a feasible pathway to exploit the high-performance BiFeO 3 -based ceramics for electrostatic energy storage.

It has been widely recognized that the structure, composition, and morphology of materials determine their properties. Sulfur-doped nickel cobalt hydroxide (S-Ni 1− x Co x (OH) 2 ) nanostructures were synthesized directly on the surface of stainless steel wire mesh via a one-step facile electrodeposition route. Comparative experiments have shown that the presence of thiourea can inhibit the reduction of nickel and cobalt ions, while promoting the formation of hydroxides and further sulfurization, thereby obtaining sulfur-doped nickel cobalt hydroxide nanostructures. The doping of sulfur has been found to improve the specific capacities of the monometallic hydroxides (Ni(OH) 2 and Co(OH) 2 ), while the synergistic effect between Ni and Co has a more pronounced impact on energy storage performance. In addition, the molar ratio of nickel to cobalt can affect the morphology of material. S-Ni 0.5 Co 0.5 (OH) 2 with a favorable morphology of nanosheet array, and porous structure exhibits the highest specific capacity, optimal rate performance, and improved cycling stability among the studied electrodes. In 1 M KOH electrolyte, the specific capacities of S-Ni 0.5 Co 0.5 (OH) 2 electrode at current densities of 1 and 10 A g −1 are 488 and 275 C g −1 , respectively, and the capacity retention is 56.6% after 10,000 cycles at the current density of 10 A g −1 .

In this work, two−dimensional Mo 2 CT x MXene pillared with transition metal complexes [Fe(III), Co(III), or Ni(II)] was prepared, which shows ultra−high performance as the anode of lithium−ion batteries (LIBs). Firstly, Mo 2 CT x was pretreated with hexadecyl trimethyl ammonium bromide (CTAB) as a surfactant and then mixed with hydrated chloride (FeCl 3 ·6H 2 O, CoCl 2 ·6H 2 O, or NiCl 2 ·6H 2 O) at room temperature. The molar ratio of MXene to hydrated chloride was 1:1. In this process, metal ions (Fe 3+ , Co 2+ , or Ni 2+ ) were successfully loaded on the nanosheets of Mo 2 CT x . The ions were combined with the surface terminated oxygen of MXene to form transition metal complexes by liquid phase agitation method. Moreover, transition metal complexes contribute a portion of their capacity and help Mo 2 CT x enhance its own capacity to a large extent. However, the electrochemical effects on Mo 2 CT x vary depending on the type of transition metal ions. As anodes of LIBs, the final discharge specific capacities after 100th cycles at 2 A g −1 were 511.68 mAh g −1 , 229.22 mAh g −1 and 78.19 mAh g −1 for Fe(III)@Mo 2 CT x , Co(III)@Mo 2 CT x , and Ni(II)@Mo 2 CT x , respectively, while the capacity of pure Mo 2 CT x after delamination was only 31.17 mAh g −1 . At 6 A g −1 , the final discharge capacity of Fe(III)@Mo 2 CT x was 227.4 mAh g −1 after 500th cycles. Therefore, Mo 2 CT x MXene pillared by the complexes, especially Fe(III) complexes, is a promising anode material with high−performance for lithium−ion batteries.

In this work, by doping the B-site of BaTiO 3 with Mg elements, we have prepared BaMg x Ti 1- x O 3- x (BM x T) films with superparaelectric behaviors. The microstructures, polarization behaviors, breakdown strength, leakage current density, and energy storage performance are investigated systematically of the BM x T films. The breakdown strength of the film reaches 7.5 MV/cm when x = 0.18, at the same time, excellent energy storage density (67.7 J/cm 3 ) and energy storage efficiency (94.9 %) are obtained, which is attributed to the doping of the acceptor element Mg. By doping Mg with a lower chemical valence state to form defect dipoles in the lattice, the breakdown strength and polarization properties of the film are improved while reducing the crystallinity of the film, forming a hysteresis loop with superparaelectric properties. This work provides a feasible route to design superparaelectric materials with simple compositions for high-performance capacitive energy-storage.

Lead-free dielectric capacitors have become a topic of great interest in response to the ever-increasing demand for high-performance and environmentally friend energy devices. As SrTiO 3 (STO) is paraelectrics, the extremely low spontaneous polarization limits the development of its energy storage applications. In this paper, the microstructure and ferroelectric properties of STO are adjusted by grain engineering to expand its application in energy storage. STO, SrTi 1-x Mn x O 3 (STM x , x = 0.01 and 0.04) and Sr 1-y La y TiMn 0.01 O 3 (SL y TM 0.01 , y = 0.01, 0.02, 0.03 and 0.04) thin films are synthesized by the sol-gel method and thoroughly investigated on the effects of A-site (La) and B-site (Mn) co-doping effects on the crystalline phase, morphology, dielectric, ferroelectric and energy storage characteristics of STO thin film. The results indicate that the SL 0.01 TM 0.01 thin film exhibits a breakdown electric field of 3666.2 kV/cm. The SL 0.02 M 0.01 thin film exhibits excellent frequency stability and low dielectric loss (<0.01) with an energy storage density of 29.5 J/cm 3 and an efficiency of 83.7 % at 2600 kV/cm. Moreover, the sample shows good frequency stability (400–2800 Hz) and thermal stability (20−140 °C). These findings indicate the potential of (Mn, La) co-doped SrTiO 3 thin film for dielectric capacitor energy storage field applications.

Titanium-niobium oxides (Ti x Nb y O 2x+2.5y ) are promising anode materials for lithium-ion batteries due to their suitable lithium insertion potential, excellent rate performance, cycling stability, and considerable capacity based on multi-electron reactions. However, the intrinsic low electrical conductivity and rapid capacity decay during cycling limit their application. In this study, nitrogen-doped Ti 2 Nb 2 O 9 nanosheets were synthesized using a chemical exfoliation method and the subsequent high-temperature phase transition. Meanwhile, introducing nitrogen atoms reduced the bandgap and increased the material's electrical conductivity. Thus, the lithium storage performance of the N-TNO electrode was improved with a reversible capacity of 348.1 mAh g −1 .

Herein, in situ chemical anchoring of nickel cobalt selenide (Ni3Se4/CoSe2) on two-dimensional (2D) black phosphorene is creatively proposed via a facile approach. The introduction of 2D black phosphorene brings abundant interfacial effects and provides fully exposed active sites. The construction of such a heterogeneous structure (BP@Ni3Se4/CoSe2) effectively buffers the volume expansion effect caused by Na ion insertion and promotes electron/ion transfer during cycling. Therefore, the BP@Ni3Se4/CoSe2 electrode exhibits superior sodium storage properties in half cells, such as a high stable discharge specific capacity (about 358.8 mA h g−1 at 1 A g−1 after 100 cycles), excellent cycling stability (up to 2500 cycles, the capacity retention rate close to 82%) and high rate performance (from the initial 0.2 A g−1 to the final 20 A g−1 and the total capacity retention rate is about 76%). In addition, BP@Ni3Se4/CoSe2 achieved a high energy density of 163.7 W h kg−1 at the power density of 136.4 W kg−1 in the sodium-ion battery full battery test. Such high performance of BP@Ni3Se4/CoSe2 is attributed to its excellent reaction kinetic characteristics. The investigation of the sodium storage mechanism of BP@Ni3Se4/CoSe2 is conducted in detail.

Some metal–organic frameworks (MOFs) cannot be used as electrode materials for lithium-ion batteries because of their inferior intrinsic electrocatalytic activity and poor conductivity. Herein, the application of two nickel (II) cluster-based pillar-layered MOFs, Ni-mba-Na ([Ni 8 (mba) 6 (Cl) 2 Na(OH − ) 3 ] n , H 2 mba is 2-mercaptobenzoic acid) and Ni-mba-K ([Ni 8 (mba) 6 (Cl) 2 K(OH − ) 3 ] n ), as electrode materials are reported. They differ from conductive MOFs because they are insulators with small specific surface areas (<10 m 2 g −1 ) and H 2 mba is an inexpensive chemical raw material. The conductivities of Ni-mba-Na and Ni-mba-K at 30 ℃ are 4.002 × 10 −10 and >10 −11 S cm −1 , respectively. They exhibit excellent lithium storage performance, stability, and high inherent density (1.835 and 1.838 g cm −3 ) and specific capacity (1091.6, and 905.6 mAh/g at the first cycle). Design recommendations for these MOFs are provided based on their structure and performance differences. This paper provides a novel application of non-conductive MOFs in the energy storage field and strategy for design of high-performance electrode materials for lithium-ion batteries.

A facile in-situ preparation strategy is proposed to anchor amorphous SnO 2 nanoparticles into the porous N-doped carbon (NC) matrix to fabricate amorphous composite powders (am-SnO 2 @p-NC), which feature the hierarchically interconnected and well interlaced porous configurations by employing polyvinylpyrrolidone as the soft template. The morphology regulation of the porous structure is precisely realized by adjusting the content of the template and the relationship between structural evolution and electrochemical performance of composite powders is accurately described to explore the optimal template dosage. The results indicate that the am-SnO 2 @p-NC-50 % composite electrode can deliver the improved lithium storage capacity and cycling performance when the content of the template is controlled at 0.500 g, in which the initial discharge specific capacity is about 1557.6 mAh/g and the reversible value retains at 841.5 mAh/g after 100 cycles at 100 mA/g. Meanwhile, the discharge specific capacity of 869.8 mAh/g is exhibited for the am-SnO 2 @p-NC-50 % composite electrode after 60 cycles when the current density is recovered from 2000 to 100 mA/g. Moreover, the Li + ions diffusion coefficient up to about 5.5 × 10 −12 cm 2 /s is calculated from galvanostatic intermittent titration technique tests, which can be partly ascribed to the conductive NC substrate that provides the high electronic conductivity, and partly to the highly porous structure that shortens Li + ions transfer pathways and guarantees the fast reaction kinetics. Therefore, the hierarchically porous engineering of carbon networks to confine amorphous transition metal oxide nanoparticles is of great significance in the development of high-performance anode materials for lithium-ion batteries.

Metal–organic frameworks (MOFs) with bimetallic centers are considered as promising electrode materials for supercapacitors due to the large specific surface area and potential redox sites. In this work, the internal structure evolution, electron transfer in the metal center, and the mechanism of action of the Mn dopant to enhance conductivity in electrochemical processes are discussed. Density functional theory (DFT) calculations show that the introduction of Mn ions greatly reduces the band gap of the Ni-MOF and increases the carrier concentration, confirming the electron transfer process of electrons from Ni2+ to Mn2+ through the bridging oxygen. Therefore, the optimal NiMn-MOF produces an impressive specific areal capacity of 1.89 mA h cm−2 at 1 mA cm−2. Meanwhile, a hybrid supercapacitor (HSC) based on the NiMn-MOF electrode and activated carbon (AC) can output a high specific energy of 67.5 W h kg−1 at a specific power of 84.5 W kg−1 with excellent cycling stability (capacity retention of 94% after 10 000 cycles). Taking advantage of the high-energy storage properties of the NiMn-MOF//AC supercapacitor device, a solar power generation system is further integrated for self-powered portable electronic applications. This work broadens the applicability of activity prediction for bimetallic MOF electrode materials with high electrochemical performance.

Aluminum sulfide is a novel light metal sulfide , which possesses multiple advantages for lithium storage, including high theoretical capacity, proper discharge potential and good conductivity. However, much research has not been done in areas related to light metal sulfide materials. Herein, we synthesized Al 2 S 3 /C nanocomposite by a facile one-step ball milling method. This simple method not only effectively achieves the uniform composite of Al 2 S 3 nanoparticles and carbon sheets, but also controls Al 2 S 3 into ultrafine nanocrystals . Al 2 S 3 /C electrode demonstrates very outstanding lithium storage performance with large reversible specific capacity (1249 mAh g -1 at 100 mA g −1 ), remarkable rate capability (670 mAh g -1 at 5000 mA g −1 ) and superior long-cycling stability (retaining 850 mAh g -1 even after 1000 cycles at 1000 mA g −1 ). Moreover, the reversible lithium storage behavior and excellent diffusion kinetics of Al 2 S 3 /C are unveiled deeply. This work provides an inspiration to develop new light metal sulfide materials for the next-generation high-performance lithium ion battery .

Phase change materials (PCM) can store heat energy through the process of phase change and keep the ambient temperature in a comfortable range, thus reaching the aim of energy conservation and emission reduction. To improve the latent heat capacity, activated carbon (AC) with a dendritic pore structure was used as the carrier, and polyethylene glycol (PEG) was loaded by vacuum adsorption method. A dendritic pore structure with a nesting pattern of macropores , mesopores, and micropores was formed through the steam activation process of waste wood chips , leading to a high load capacity (70%) and uniform distribution, which showed high heat storage performance (ΔH m reached 116 J/g). Then the form-stable phase change material with satisfactory performance (AC/PEG-70) was combined with wood flour/ high-density polyethylene (WF/HDPE) through blending and hot pressing to fabricate phase change heat storage wood-plastic composite material (A-WPC). When the AC/PEG-70 content was 50%, the elongation at break increased by 167% (20%), and the rigidity of the material enhanced. ΔH m of A-WPC-50 was 19 J/g, undoubtedly at this point, achieving the expected thermal performance. Thus, we prepared an eco-friendly wood-plastic composite with high latent heat capacity and high stability by using the dendritic pore structure of biomass activated carbon-based form-stable PCM, which has great significance in promoting energy conservation and emission reduction, responding to green technological innovation and promoting the development of the green and low-carbon industry.
