Natrium- und Kaliumionenbatterien (SIBs und PIBs) sind dabei aufstrebende Stars im Bereich der wiederaufladbaren Batterien, angetrieben durch den dringenden Bedarf an kostengünstigen und industriell skalierbaren Energietechnologien. Trotz ihres Potenzials behindern jedoch bestimmte zentrale Herausforderungen…
Despite their favorable high energy density and potential for CO₂ recycling, Na-CO₂ batteries have been held back by limitations in cycling capability, stemming from the sluggish CO₂ reduction/evolution reaction (CO₂RR/CO₂ER) kinetics at CO₂ cathode and unmanageable deposition/stripping of metallic Na…
Owing to the low potential (vs K/K⁺), good cycling stability, and sustainability, carbon-based materials stand out as one of the optimal anode materials for potassium-ion batteries (PIBs). However, achieving high-rate performance and excellent capacity with the current carbon-based materials is challenging…
Considering environmental changes and the demand for more sustainable energy sources, stricter requirements have been placed on electrode materials for sodium and potassium-ion batteries, which are expected to provide higher energy and power density while being affordable and sustainable. Vanadium sulfide-based…
Electrochemical carbon dioxide (CO2) conversion technologies have become new favorites for addressing environmental and energy issues, especially with direct electrocatalytic reduction of CO2 (ECO2RR) and alkali metal-CO2 (M–CO2) batteries as representatives. They are poised to create new economic drivers…
Abstract Alkali metal–CO2 batteries, which combine CO2 recycling with energy conversion and storage, are a promising way to address the energy crisis and global warming. Unfortunately, the limited cycle life, poor reversibility, and low energy efficiency of these batteries have hindered their commercialization.…
Sodium-carbon dioxide (Na-CO2) batteries are regarded as promising energy storage technologies because of their impressive theoretical energy density and CO2 reutilization, but their practical applications are restricted by uncontrollable sodium dendrite growth and poor electrochemical kinetics of CO2…
Despite their variable valence and favorable sodiation/desodiation potential, vanadium sulfides (VSx) used as anode materials of sodium-ion batteries (SIBs) have been held back by their capacity decline and low cycling capability, associated with the structure distortion volume expansion and pulverization.…
Owing to the cost-effectiveness, Earth abundance, and suitable redox potential, potassium-ion batteries (PIBs) stand out as one of the best candidates for large-scale energy storage systems. However, the large radius of K+ and the unsatisfied specific capacity are the main challenges for their commercial…
Abstract Fused‐ring electron donors boost the efficiency of organic solar cells (OSCs), but they suffer from high cost and low yield for their large synthetic complexity (SC > 30%). Herein, the authors develop a series of simple non‐fused‐ring electron donors, PF1 and PF2, which alternately consist of…
Potassium-ion batteries (PIBs) configurated by organic electrodes have been identified as a promising alternative to lithium-ion batteries. Here, a porous organic Polyimide@Ketjenblack is demonstrated in PIBs as a cathode, which exhibits excellent performance with a large reversible capacity (143 mAh…
