TL;DR: In this paper, the dissolution behaviors of Mn and Ni were examined systematically under various conditions such as state of charge (SOC), temperature, storage time, and crystal structure of LNMO.

TL;DR: A multiscale theoretical methodology is developed to reveal the mechanism of Li(+) transport in a SEI film, applicable to model general transport properties, such as ionic conductivity, for SEI films on the surface of other electrodes, from the atomic scale to the mesoscale, as well as aging phenomenon.

TL;DR: It is found that the contact between Li2CO3 and LiF can promote space charge accumulation along their interfaces, which generates a higher ionic carrier concentration and significantly improves lithium ion transport and reduces electron leakage.

TL;DR: In this paper, the solid electrolyte interphase (SEI) forms during the initial cycles in lithium ion batteries and evolves throughout the battery life, and it is found that the SEI chemistry has a distinct influence on its impedance, which may ultimately impact the battery performance.

TL;DR: The aging mechanism has been extensively investigated during the past decade and many efforts have been devoted to develop nanostructured electrode materials to avoid the mechanical degradation and improve the cycling stability of lithium ion batteries.
