While α-MnO2 has been intensively studied for zinc batteries, δ-MnO2 is usually believed to be more suitable ion storage with its layered structure. Unfortunately, the extraordinary Zn performance that should exhibit not yet achieved due frustrating structural degradation during charge-discharge cycles. Here, we found Na and water molecules pre-intercalation can effectively activate stable of δ-MnO2. Our results reveal resulted Zn//pre-intercalated battery delivers an extraordinarily...
Abstract The dendritic issue in aqueous zinc‐ion batteries (ZBs) using neutral/mild electrolytes has remained an intensive controversy for a long time: some researchers assert that dendrites severely exist while others claim great cycling stability without any protection. This is clarified by investigating charge/discharge‐condition‐dependent formation of Zn dendrites. Lifespan degradation (120 to 1.2 h) and voltage hysteresis deterioration (134 380 mV) are observed with increased current...

Abstract Hydrogel materials are receiving increasing research interest due to their intriguing structures that consist of a crosslinked network polymer chains with interstitial spaces filled solvent water. This feature endows the characteristics being both wet and soft, making them ideal candidates for electrolyte flexible energy storage devices, such as supercapacitors rechargeable batteries under intensive studies nowadays. More importantly, highly abundant tunable chemistries these...
Hearing loss is the most common sensory deficit in humans, affecting 1 500 newborns. Due to its genetic heterogeneity, comprehensive diagnostic testing has not previously been completed a large multiethnic cohort. To determine aggregate contribution inheritance makes non-syndromic hearing loss, we performed clinical with targeted genomic enrichment and massively parallel sequencing on 1119 sequentially accrued patients. No patient was excluded based phenotype, or previous testing. Testing...
Abstract Stretchable devices need elastic hydrogel electrolyte as an essential component, while most hydrogels will lose their stretchability after being incorporated with strong alkaline solution. This is why highly stretchable zinc–air batteries have never been reported so far. Herein, super‐stretchable, flat‐ (800% stretchable) and fiber‐shaped (500% are first developed by designing alkaline‐tolerant dual‐network electrolyte. In the electrolyte, sodium polyacrylate (PANa) chains...
Abstract Hydrogel electrolytes have attracted increasing attention due to their potential uses in the fabrication of flexible solid‐state batteries. However, development hydrogel is still initial stage and number available strategies limited. Ideally, electrolyte should exhibit suitable ionic conductivity rate, mechanical strength, biocompatibility for safety.

Degradable energy storage systems (ESSs) have been proposed to tackle increasing e-wastes such as heavy metals and toxic organic electrolytes. However, currently reported degradable ESSs are scarce because it is very difficult make all of the electrochemical components they must be stable for storage.
