Summary: Recent studies have shown that 2D materials, such as siloxene and germanane, can exhibit excellent performance as electrodes in alkali metal ion batteries. The improved electrochemical behavior of these materials is likely due to their limited volume change during charge and discharge, which is based on an intercalation mechanism rather than alloying. To combine the cheapness of Si and high electronic conductivity of Ge, we propose a new series of layered materials called siliganes, which are 2D Si-Ge composites. Among them, siligane_Si0.1Ge0.9 demonstrated the best electrochemical performance in Na- and K-ion batteries.

Summary: Li+/Na+ exchange is an effective method for preparing high-performance Mn-based layered cathodes for Li-ion batteries. However, the detailed structural changes during the ion-exchange process are less studied. This study combines in situ synchrotron X-ray diffraction, density functional theory calculations, and electrochemical tests to investigate the structural changes during the ion-exchange process of an Mn-only layered cathode. The findings reveal the thermodynamic favorability of Li+/Na+ exchange and the presence of two tandem topotactic phase transitions.

Summary: In this work, an ultra-stable electrode-solid electrolyte composite for high-performance all-solid-state lithium-ion batteries (ASSLIBs) is fabricated by uniformly covering each MgH2 nanoparticle with ultrathin Mg(BH4)(2) layers on the surface of graphene. The presence of Mg(BH4)(2) layers enhances the Li ion conductivity of the graphene-supported MgH2 nanoparticles, resulting in uniform stable interfaces with high ionic and electronic conductivity. Additionally, the stable framework of inactive Li2B6 and the structural support of graphene alleviate volume change and facilitate intimate contact, leading to an ultrahigh specific capacity of 800 mAh g(-1) for MgH2 after 350 cycles at 2 A g(-1).
