Abstract Triboelectrification is a well-known phenomenon that commonly occurs in nature and our lives at any time place. Although each every material exhibits triboelectrification, its quantification has not been standardized. A triboelectric series qualitatively ranked with regards to polarization. Here, we introduce universal standard method quantify the for wide range of polymers, establishing quantitative triboelectrification as fundamental materials property. By measuring tested liquid...
A long debate on the charge identity and associated mechanisms occurring in contact-electrification (CE) (or triboelectrification) has persisted for many decades, while a conclusive model not yet been reached explaining this phenomenon known more than 2600 years! Here, new method is reported to quantitatively investigate real-time transfer CE via triboelectric nanogenerator as function of temperature, which reveals that electron dominant process between two inorganic solids. study surface...

The rechargeable lithium ion (Li-ion) battery market was $11.8 billion in 2011 and is expected to increase $50 by 2020. With developments consumer electronics as well hybrid electric vehicles, Li-ion batteries demand will continue increase. However, are not widely recycled because currently it economically justifiable (in contrast, at present more than 97% lead-acid recycled). So far, no commercial methods available recycle with different cathode chemistries efficiently. Considering our...
