Potassium-ion capacitors (PICs) combine the benefits of high energy density and excellent power at a lower cost than lithium storage technology. However, developing high-rate stable anode materials that are compatible with capacitor-type counterparts remains formidable challenge. In this study, tellurium-doped MoS2/carbon composite nanotubes (Te-MoS2/C NTs), featuring one-dimensional hollow structure decorated interlayer-extended few-layer nanosheets, were designed as for potassium storage. The Te-MoS2/C NTs achieve notable average reversible capacity 417.8 mA h g−1 0.05 A 215.0 5.0 g−1. Additionally, it maintains retention rate 95.6% after 300 cycles 2.0 Moreover, functional theory calculations validate enhanced K+ adsorption diffusion, attributed to Te doping interlayer expansion MoS2. PICs based on also achieves an 113.6 W 12.1 kW kg−1, alongside cycling stability.

Abstract Rechargeable Mg batteries are an energy‐storage technology suitable for large‐scale applications, but the lack of high‐performance cathode materials is currently hindering their development. Conversion‐type cathodes break limits Mg‐intercalation principle, existing structural design strategies mostly focus on morphology optimization to increase active reaction interfaces. The present study reveals that crystal structure also plays a significant role in Mg‐storage activity conversion reactions. Two types CoSe 2 with orthorhombic and cubic phases synthesized from ZIF‐67 comparatively investigated as RMBs. Despite exhibiting similar micromorphology lower specific surface area, phase demonstrates superior capacity, rate performance, charge transfer resistance, higher solid‐state 2+ diffusion coefficients compared . Mechanism studies reveal more thorough reversible, involving redox both cations anions. Further theoretical computations indicate at (010) plane , along sites Se‒Se bonds, facilitates via co‐redox This underscores importance conversion‐type RMB materials.

Abstract Sodium‐ion fiber supercapacitor (AFSIC) are promising candidates for wearable devices. However, their practical implementation is hindered by the absence of cathodes with fast Na‐ion diffusion kinetics to match anode and poor temperature adaptability conventional electrolytes. To address these challenges, a carbon‐coated NaV 3 O 8 nanowires (NaNVO@C 10 ) low energy barriers designed, enabling rapid reversible intercalation/de‐intercalation. By leveraging liquid crystalline phase induced characteristic graphene oxide (GO), NaNVO@C /rGO cathode fabricated using wet spinning. This achieves large volume capacitive 565 F cm −3 . In parallel, novel dual co‐solvent electrolyte (SLPHNa) developed introducing sulfolane ethylphosphate as co‐solvent. synergistically reshape solvation sheath, thereby improving cycle stability enhancing from −60 80 °C AFSIC. The resulting /rGO//MXene AFSIC exhibits remarkable density 35 mWh , maintains 9.3 even at °C, along an ultra‐long lifespan 000 cycles under all‐weather condition. Moreover, device 82% its initial capacitance after 1000 bending cycles, showing excellent mechanical durability. work offers new insights into development high performance sodium‐ion supercapacitors.

ABSTRACT Although potassium (K) vanadyl phosphate fluoride (KVPO₄F) is considered one of the most promising cathode materials for K‐ion batteries, its practical application hindered by poor electronic conductivity and fluorine (F) loss during synthesis process. In this work, a novel synthetic route designed to realize advanced KVPO₄F material (denoted as KVPO 4 F@C) adopting in situ carbon coating approach initiated isobutanol molecular intercalation, delivering two distinct characteristics high F‐containing limited particle growth. On hand, as‐generated layer enhances prevents agglomeration calcination other as‐introduced V–F–C bonds at KVPO₄F/C interface realizes F@C without large‐scale F loss. As result, retains discharge capacity 63.94 mAh g⁻¹ after 100 cycles 2C well superior rate performance. This study highlights critical role pathway enhancing electrochemical performance cathode.
