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.

Stabilizing the Performance of High-Capacity Sulfur Composite Electrodes by a New Gel Polymer Electrolyte Configuration

Stabilizing the Performance of High‐Capacity Sulfur Composite Electrodes by a New Gel Polymer Electrolyte Configuration

The gelling solution: The capacity of a Li–S battery with a high active-material loading is stabilized by using a gel polymer electrolyte (GPE). The GPE enables stable performance close to the theoretical capacity of a S–C composite, prevents sulfur dissolution, and reduces migration of polysulfides to the anode. The functional mechanism of the GPE membrane is revealed by investigating its morphology and the Li-anode/GPE interface at various discharge/charge states.

Enhanced Electrochemical Performance of Mesocarbon‐Microbeads‐Based Anodes through Air Oxidation for Sodium‐Ion Batteries

What's in store: Inspired by the stabilization process for carbon fibers, air oxidation is introduced as a modification for mesocarbon microbeads (MCMBs). The introduction of oxygen atoms contribute to the crosslinking between carbon layers and adjust the disorder degree of MCMBs by increasing defect sites. The larger interlayer spacing and increased defect sites caused by oxidation are beneficial for MCMBs to store and transfer sodium ions.

Electrolyte additives containing transition-metal salts are demonstrated to stabilize Li2S cathodes by producing conductive and protective surface encapsulation layers on the Li2S particles via in situ chemical reactions that generate transition-metal sulfides electrochemically inactive within the cycling voltage window. The electronic valence band structure of the as-generated encapsulation layer is critical to the initial charging overpotential of the Li2S particles.
