TL;DR: In this paper, the authors discuss the recent achievements, challenges, and opportunities of four important "beyond Li-ion" technologies: Na-ion batteries, K-ion, all-solid-state batteries, and multivalent batteries.

TL;DR: In this article, the authors demonstrate that density functional theory, with the recently developed strongly constrained and appropriately normed (SCAN) functional, has advanced to a point where both facets of the stability problem can be reliably and efficiently predicted for main group compounds, while transition metal compounds are improved but remain a challenge.

TL;DR: Through real-time tracking of Li+ migration using operando electron energy-loss spectroscopy, it is revealed that facile transport in Li4+xTi5O12 is enabled by kinetic pathways comprising distorted Li polyhedra in metastable intermediates along two-phase boundaries.

TL;DR: In this article, a major bottleneck for the development of Mg batteries is the identification of liquid electrolytes that are simultaneously compatible with the Mg-metal anode and high-voltage cathodes.

TL;DR: In this paper, the authors investigate Mg intercalation into the spinel-MgxCr2O4 system and calculate the voltage curve for Mg insertion at room temperature and the activation barriers for mg diffusion, respectively, at different Mg concentrations in the Cr 2O4 structure.
