Electronic polarizability as the fundamental variable in the dielectric properties of two-dimensional materials
Tian Tian, Declan Scullion, Dale Hughes +5
The dielectric constant, which defines the polarization of the media, is a key quantity in condensed matter. It determines several electronic and optoelectronic properties importan…
Quantifying the effect of electrical conductivity on the rate-performance of nanocomposite battery electrodes
Ruiyuan Tian, Nolito Alcala, Stephen JK ONeill +7
While it is well-known that electrode conductivity has a critical impact on rate-performance in battery electrodes, this relationship has been quantified only by computer simulatio…
Do 2D material-based battery electrodes have inherently poor rate-performance?
Ruiyuan Tian, Madeleine Breshears, Dominik V Horvath +1
Two dimensional materials show great potential for use in battery electrodes and are believed to be particularly promising for high-rate applications. However, there does not seem…
Using chronoamperometry to rapidly measure and quantitatively analyse rate-performance in battery electrodes
Ruiyuan Tian, Paul J. King, Joao Coelho +5
For battery electrodes, measured capacity decays as charge/discharge current is increased. Such rate-performance is important from a practical perspective and is usually characteri…
