High‐voltage lithium metal batteries (LMBs) are a promising high‐energy‐density energy storage system. However, their practical implementations are impeded by short lifespan due to uncontrolled lithium dendrite growth, narrow electrochemical stability window, and safety concerns of liquid electrolytes. Here, a porous composite aerogel is reported as the gel electrolyte (GE) matrix, made of metal–organic...
Carbon‐based single‐atom catalysts (CSACs) have recently received extensive attention in catalysis research. However, the preparation process of CSACs involves a high‐temperature treatment, during which metal atoms are mobile and aggregated into nanoparticles, detrimental to the catalytic performance. Herein, an ion‐imprinting derived strategy is proposed to synthesize CSACs, in which isolated metal–nitrogen–carbon...
Developing supermechanically resilient hard carbon materials that can quickly accommodate sodium ions is highly demanded in fabricating durable anodes for wearable sodium‐ion batteries. Here, an interconnected spiral nanofibrous hard carbon fabric with both remarkable resiliency (e.g., recovery rate as high as 1200 mm s−1) and high Young's modulus is reported. The hard carbon nanofabrics are prepared...
Incorporating nanofillers is one of the promising approaches for simultaneously boosting the ionic conductivity and mechanical properties of solid polymer electrolytes (SPEs). However, effectively creating faster ion‐conduction pathways via nanofillers still remains a big challenge. Herein, core–shell protein–ceramic nanowires for more efficiently building fast ion‐conduction networks in SPEs are...
