Chloride-ion batteries (CIBs) have drawn growing attention in large-scale energy storage applications owing to their comprehensive merits of high theoretical density, dendrite-free characteristic, and abundance chloride-containing materials. Nonetheless, cathodes for CIBs are plagued by distinct volume effect sluggish Cl- diffusion kinetics, leading inferior rate capability short cycling life. Herein, an unconventional Ni5 Ti-Cl LDH is reported with a nickel ratio as cathode material CIB....
Abstract A hierarchical structure is successfully synthesized by coating polypyrrole (PPy) on the surface of carbon/saponite superlattice (denoted as PPy@C/SAP), and applied low volume‐expansion insertion‐type anode for Li, Na, K storage.The synergistic effect metal Ni, Fe doping, carbon/silicate superlattice, abundant oxygen vacancies PPy leads to a good electronic conductivity large current discharging capability. As Si‐based material, PPy@C/SAP has excellent storage capability Li (659 mAh...
MoNiCo-Cl layered double hydroxides (LDHs) with rich oxygen vacancies are proposed as cathodes toward chloride ion batteries. Mo 6+ can not only modulate the electronic properties at adsorption sites, but improve redox activity of LDHs.
Aqueous chloride-ion batteries (ACIBs) with environmental friendliness and high safety hold great potential to fulfill the green energy demand for ocean desalination. Herein, first time, a composite consisting of Cl–-intercalated CoFe layered double hydroxides (CoFe–Cl-LDH) cross-linked CNTs (CoFe–Cl-LDH/CNT) is synthesized demonstrated be novel high-performance anode ACIBs in neutral NaCl aqueous solution. While exhibiting initial capacity ∼190 mAh g–1 at 200 mA g–1, CoFe–Cl-LDH/CNT capable...
A carbonate intercalated magnesium aluminum layered double hydroxide (Mg 2 Al 1 –CO 3 LDH) was synthesized and used as an anode material for lithium-ion batteries (LIBs), possessing a unique mechanism the storage of Li + by conversion reaction.
Anode materials with simultaneously large capacity and low working voltage have always been one of the pursuing goals in development lithium-ion batteries. In this report, erdite NaFeS2 was synthesized by phase conversion Fe-saponite for first time, which displays attractive lithium-storage performance as an anode material. Taking into consideration that can be regarded sodium pre-embedded FeS2, a thorough comparison between FeS2 carried out. Theoretical calculation reveals has metallic...
A fluoride-ion battery (FIB) is a novel type of energy storage system that has higher volumetric density and low cost. However, the high working temperature (>150 °C) unsatisfactory cycling performance cathode materials are not favorable for their practical application. Herein, fluoride ion-intercalated CoFe layered double hydroxide (LDH) (CoFe-F LDH) was prepared by facile co-precipitation approach combined with ion-exchange. The CoFe-F LDH shows reversible capacity ∼50 mAh g-1 after 100...
Transition-metal compounds (oxides, sulfides, hydroxides, etc.) as lithium-ion battery (LIB) anodes usually show extraordinary capacity larger than the theoretical value due to transformation of LiOH into Li2O/LiH. However, there has rarely been a report relaying Li2O/LiH main reaction for LIBs, strong alkalinity leading deterioration. In this work, layered silicate MgAl saponite (MA-SAP) is applied -OH donor generate anode material LIBs first time. The MA-SAP maintains structure during...
Abstract As one kind of promising energy storage device, dual‐ion batteries (DIBs) have attracted extensive attention because their high voltage, environmental friendliness, and low cost. However, they generally suffer from power density resulting sluggish kinetic electrolyte anion intercalation. In this work, a new strategy to break through the trade‐off in DIBs is proposed. A vanadium‐doped anatase synthesized by hydrothermal method used as cathode DIB (employing Li anode). During...
In recent years, CsPbBr3 perovskite solar cells have attracted lots of attentions due to their excellent temperature and humidity stability. To overcome low solubility challenge PbBr2 CsBr, most studies used sequential solution-processing techniques (SSPTs) prepare films. However, in the process deposition uneven reaction could lead generation impure phase (e.g. CsPb2Br5 Cs4PbBr6), which would deteriorate performance device. Here, a solvent-vapor annealing (SA) method has been proposed for...
