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.

Bottom-Up Construction of Porous Organic Frameworks with Built-In TEMPO as a Cathode for Lithium–Sulfur Batteries

Bottom‐Up Construction of Porous Organic Frameworks with Built‐In TEMPO as a Cathode for Lithium–Sulfur Batteries

Keep the TEMPO: Stable porous organic frameworks (POFs) with a built-in radical moiety (TEMPO) were prepared by a bottom-up strategy. These TEMPO-POFs were applied as host cathode materials for Li−S batteries with good cycling performance. Furthermore, TEMPO-POFs with sulfur embedded showed excellent rate capability with limited capacity loss at rates of 0.1–1 C.

Synthesis of Hollow SnO2/SnS2 Hybrids and Their Application in Sodium-Ion Batteries

Synthesis of Hollow SnO2/SnS2 Hybrids and Their Application in Sodium‐Ion Batteries

Stress relief: A facile two-step hydrothermal route is introduced to prepare hollow SnO2/SnS2 hybrids. Subsequently, their electrochemical performances as anodes in Na-ion batteries are investigated. The as-prepared hollow SnO2/SnS2 hybrids are composed of ultrafine SnS2 nanosheets, which directly grow on the pre-grown hollow SnO2 hollow spheres. In the structure, both the SnO2 hollow structures and surrounding SnS2 nanosheets are able to alleviate internal stress during sodiation/desodiation.

Rational Design of Stable Dianions by Functionalizing Polycyclic Aromatic Hydrocarbons

Design of stable dianions: First-principles calculations are carried out to explore how to enhance the dianion stability of polycyclic hydrocarbon molecules by substituting the H atoms by other electronegative ligands and/or core C atoms by electron deficient B atom. Indeed, the dianion of B2C8(CN)8 (see picture) is more stable than its monoanion with a total energy difference of 1.97 eV.

Mechanism of Na‐Ion Storage in Hard Carbon Anodes Revealed by Heteroatom Doping

The structure of hard carbon is systematically tuned by heteroatom doping, which reveals the mechanism of sodium storage in hard carbon. Through P- and S-doping, the d-spacing of hard carbon is dilated, which leads to a higher plateau capacity, while P- and B-doping generate more defects site, which enhances the first sodiation capacity. Computational studies provide indispensable confirmation of the mechanism.
