Engineering Triboelectric Paper for Energy Harvesting and Smart Sensing

Advanced Materials, EarlyView.
Engineering nano‐graphite coated paper (NG@P) is produced to serve as triboelectric layers and electrodes for TENGs. Ultra‐high power density above 14 kW m−2 is achieved due to the electrostatic discharge on the surface. Moreover, smart home sensors are fabricated using the NG@P for motion sensing and sleep monitoring, which could be used for security ...

Iodine‐Doped Sodium Vanadate Cathode for Improved Zn Ion Diffusion Kinetics

Advanced Materials, EarlyView.
An iodine‐doping strategy is developed to modify the Na2V6O16·3H2O cathode for aqueous zinc‐ion batteries, effectively reducing the electrostatic interaction between zinc ions and the host structure. This modification enables faster diffusion and higher storage capacity of zinc ions. Abstract The electrostatic interaction between zinc ions and the host

10 Years Development of Potassium‐Ion Batteries

Advanced Materials, EarlyView.
Significant progress is made in PIBs over the past decade, but the improvements based on half‐cell testing, low mass loading, and low energy density are insufficient for practical applications. This review summarizes the challenges and strategies for PIBs, highlights the importance of further research focusing on full cells, and provides an analysis of
