Electronic properties and storage capability of two-dimensional nitridosilicate MnSi2N4 from first-principles

AIP Advances, 2022
Through first-principles calculations, we successfully identified a two-dimensional layered nitridosilicate-MnSi2N4 in hexagonal structure, as a novel anode for lithium (Li) and sodium (Na) ion batteries.

A chemo-mechanical model coupled with thermal effect on the hollow core–shell electrodes in lithium-ion batteries

Theoretical and Applied Mechanics Letters, 2017
Electrode is a key component to remain durability and safety of lithium-ion (Li-ion) batteries. Li-ion insertion/removal and thermal expansion mismatch may induce high stress in electrode during charging and discharging processes.

Resolving a Discrepancy in Diffusion Potentials, with a Case Study for Li-Ion Batteries [PDF]

Journal of The Electrochemical Society, 2016
Overpotentials induced by liquid-phase composition variation can be important when electrochemical devices are operated at high current. The dominant models that describe such ‘diffusion potentials’ are Nernst–Planck (dilute-solution) theory and Onsager–Stefan–Maxwell (concentrated-solution) theory.

Revealing the Rate-Limiting Li-Ion Diffusion Pathway in Ultrathick Electrodes for Li-Ion Batteries

The Journal of Physical Chemistry Letters, 2018
Increasing the loading of active materials by thickening the battery electrode coating can enhance the energy density of a Li-ion cell, but the trade-off is the much reduced Li+ transport kinetics. To reach the optimum energy and power density for thick electrodes, the effective chemical diffusion coefficient of Li+ ( DLi) must be maximized.
