Batteries and Supercapacitors

batteriesLithium-ion or otherwise, batteries keep lots of things going, and enable a mobile lifestyle: from mobile phones to intercontinental air travel. Batteries are complex devices whose overall performance and usefulness depend on many factors such as energy density, efficiency, durability, and sustainability. Research in this area is by nature interdisciplinary and involves chemists, physicists, materials scientists, and engineers.

An FeIII Azamacrocyclic Complex as a pH-Tunable Catholyte and Anolyte for Redox-Flow Battery Applications

An FeIII Azamacrocyclic Complex as a pH‐Tunable Catholyte and Anolyte for Redox‐Flow Battery Applications

Iron in energy storage: A reversible Fe3+/Fe2+ redox couple of an aza-macrocyclic complex has a pH-tunable 590 mV potential range useful for redox-flow battery (RFB) applications. Tunable redox, fast electrochemical kinetics, exceptional stability and cyclability of this complex is promising for the design of both aqueous catholytes and anolytes for RFBs that utilize the earth-abundant element, iron.

Role of Acid in Tailoring Prussian Blue as Cathode for High-Performance Sodium-Ion Battery

Role of Acid in Tailoring Prussian Blue as Cathode for High‐Performance Sodium‐Ion Battery

Tailored cathodes: Prussian blue (PB) samples are synthesized through a hydrothermal method with the assistance of acid. The acid not only triggers the chemical reaction to form cubic PB, but also acts as an etching reagent, tailoring the PB morphology. The as-obtained cubic PB with concave centers demonstrates superior cycle stability and rate performance, with good capacity retention (see scheme).

Improving the Structural Stability of Li-Rich Layered Cathode Materials by Constructing an Antisite Defect Nanolayer through Polyanion Doping

Improving the Structural Stability of Li‐Rich Layered Cathode Materials by Constructing an Antisite Defect Nanolayer through Polyanion Doping

Defect-perfect: Lithium-rich layered Li1.16(Ni0.25Mn0.75)0.84O2 oxide with an antisite-defect layer on the surface is prepared by boracic polyanion doping. The layer retards the drastic layered-to-spinel phase transition and eliminates the concomitant amorphous phase by decreasing the concentration of Li+ vacancies during high-voltage charging, which significantly improves the capacity retention and decreases the voltage decay.

Atomistic Origins of Ductility Enhancement in Metal Oxide Coated Silicon Nanowires for Li-Ion Battery Anodes

Atomistic Origins of Ductility Enhancement in Metal Oxide Coated Silicon Nanowires for Li‐Ion Battery Anodes

Molecular dynamics simulations of silica- and alumina-coated silicon nanowires under uniaxial tension reveal atomistic origins for mechanical property enhancement in coated nanowires. Uncoated nanowires fail by amorphization within a localized shear band, while coated undergo dislocation twinning and large-scale amorphization, improving ductility without significant reduction in tensile strength, increasing apparent toughness by 2–4 times.

The Role of the Electrode Surface in Na–Air Batteries: Insights in Electrochemical Product Formation and Chemical Growth of NaO2

The Role of the Electrode Surface in Na–Air Batteries: Insights in Electrochemical Product Formation and Chemical Growth of NaO2

In NaO2 batteries, the chemical crystallization (growth) of NaO2 is highly sensitive to the surface energy and O2/O2 affinity of the electrode. On gold, strong interaction with O2 leads to formation of small NaO2 flakes, while on carbon (low surface energy) large NaO2 cubes are found. This has significant impact on the cell performance.

Theoretical Studies on the Charging and Discharging of Poly(acrylonitrile)-Based Lithium-Sulfur Batteries

Theoretical Studies on the Charging and Discharging of Poly(acrylonitrile)‐Based Lithium‐Sulfur Batteries

Taking charge: Plausible mechanisms for battery charging and discharging at a SPAN cathode are identified. In both discharging and charging, Li atoms preferentially coordinate with N atoms on the backbone, leading to strong Li-SnPAN adsorption energies. Moreover, it is rather difficult to seprate a dissociated SnLi fragment from the backbone, which provides a plausible explanation for the ability of a SPAN cathode to hinder polysulfides from diffusing to the cathode, leading to a reduction of the polysulfide shuttle mechanism.
