Phase transition in porous electrodes.

It is shown by Monte Carlo simulation that electrochemical thermodynamics of electrolytes in a porous electrode is qualitatively different from that in the bulk with a planar electrode. In particular, first order phase transitions occur in porous electrodes when the pore size is comparable to the ion size of the electrolytes: as the voltage is increased from zero, the surface charge density and...

Novel CV for Phase Transformation Electrodes

Phase transformation cyclic voltammetry (CV) was developed by integrating mixed-control phase transformation theory and charge transfer effect with traditional CV model. This mixed-control phase transformation CV model was validated by good agreement between experimental CV data and simulated values from phase transformation CV for LiFePO4. The lithium ion diffusion coefficient (10-16 m2 s-1) o...

Visualization of anisotropic-isotropic phase transformation dynamics in battery electrode particles

Anisotropy, or alternatively, isotropy of phase transformations extensively exist in a number of solid-state materials, with performance depending on the three-dimensional transformation features. Fundamental insights into internal chemical phase evolution allow manipulating materials with desired functionalities, and can be developed via real-time multi-dimensional imaging methods. Here, we re...

Nonlinear dynamics of capacitive charging and desalination by porous electrodes.

The rapid and efficient exchange of ions between porous electrodes and aqueous solutions is important in many applications, such as electrical energy storage by supercapacitors, water desalination and purification by capacitive deionization, and capacitive extraction of renewable energy from a salinity difference. Here, we present a unified mean-field theory for capacitive charging and desalina...

Galvanostatic Intermittent Titration Technique for Phase-Transformation Electrodes

A novel galvanostatic intermittent titration technique (GITT) and a novel potentiostatic intermittent titration technique (PITT) for phase-transformation electrodes were developed by integrating mixed control phasetransformation theory with traditional GITT and PITT methods. The contribution of the strain accommodation energy to the thermodynamic driving force for phase transformation was asses...
