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.

Readily Exfoliated TiSe2 Nanosheets for High-Performance Sodium Storage

Readily Exfoliated TiSe2 Nanosheets for High‐Performance Sodium Storage

The sodium storage capability of TiSe2 is studied for the first time. The combined in situ XRD and ex-situ HRTEM results suggest that sodium storage is achieved through a multi-step intercalation/deintercalation mechanism. Besides, bulk TiSe2 is easily exfoliated into nanosheets, and might be a promising 2D material platform for energy and electronic applications.

This can be used for soluble species whose concentration is unknown, such as soluble sulfur and polysulfides in lithium-sulfur batteries. The approach can also be applied to ion-insertion electrodes, where non-linearity of concentration and voltage changes would produce unrealistic evaluations of the diffusion coefficient by the classical analysis of GITT data.

Vital choice: The effect of solvent on the molecular life of O2 and Li+ produced during the discharge of aprotic Li–O2 batteries is investigated by molecular dynamics simulation. The stability of the Li+ solvation shell largely depends on the solvent donor number. However, the association rate of Li+ and O2 does not necessarily correlate with this solvent property.

Reduced Shuttle Effect of Lithium−Sulfur Batteries by using a Simple Graphite‐Modified Separator with a Preformed SEI Film

Defense barrier: The formed SEI film on a graphite surface inhibits the graphite exfoliation caused by co-intercalation of solvents. Thus, the stable graphite layer with a preformed SEI can function as an effective physical barrier to suppress the polysulfide shuttle and enhance the utilization of the trapped active material. As a result, Li−S cells using the graphite-decorated separator exhibit excellent cycle stability with a low capacity decay of 0.13 % per cycle.

This new material is synthesized by adding polyether amine groups onto mixed propylene oxide and ethylene oxide blocks to make p-phenylenediamine and terephthalaldehyde units and form electroactive Schiff-base groups along the macromolecule.

Preparation of Layered-Spinel Microsphere/Reduced Graphene Oxide Cathode Materials for Ultrafast Charge–Discharge Lithium-Ion Batteries

Preparation of Layered‐Spinel Microsphere/Reduced Graphene Oxide Cathode Materials for Ultrafast Charge–Discharge Lithium‐Ion Batteries

Fidget spinels: layered-spinel microspheres are prepared on reduced graphene oxide in situ, forming cathode materials for Li-ion batteries. They deliver a considerable capacity of 145 mA h g−1 at an ultrahigh charge– discharge rate of 60 C (12 A g−1).
