TL;DR: In this paper, a porous MXene monolith with locally laminated structure is produced by the alkali-assisted self-assembly of MXene from liquid phase, wherein alkali promotes the "face-to-face" stacking of the MXene nanosheets by weakening the electrostatic repulsion during the process of selfassembly, and the balance of laminated and porous structures is the key to simultaneously provide sufficient Na+ storage sites and multi-dimensional ion transport pathways.

Unraveling the Key Atomic Interactions in Determining the Varying Li/Na/K Storage Mechanism of Hard Carbon Anodes
Qi Li,Jun Zhang,Lixiang Zhong,Fushan Geng,Ying Tao,Chuannan Geng,Shuzhou Li,Bingwen Hu,Quan-Hong Yang +8 more
TL;DR: In this article , a glassy carbon, the extreme form of hard carbon with dominant sp2 hybridization and only Stone-Wales defects, is selected as a model anode, and its Li/Na/K-ion storage mechanisms are exactly consistent with the theoretical prediction.

Discrete Graphitic Crystallites Promise High‐rate Ion Intercalation for KC8 Formation in Potassium Ion Batteries
TL;DR: In this article , a carbon anode material containing the medium-size discrete graphitic crystallites is reported, produced by heating non-graphitizable carbon above 2800 °C, which promotes the formation of high-stage graphite-intercalation compound (GIC) KC8.

Insight into the composition effect of nickel cobalt layered double hydroxide nanoarrays with the enhanced synergistic effect for supercapacitor electrode
TL;DR: In this article , the composition effects on the structure and capacitive performance of NiCo layered double hydroxide (NiCo LDH) nanostructured is discussed, and subsequently the structural diversity of LiDAR nanoarrays is regulated via an alkali conversion, resulting in gradual increase surface content of Ni3+ and Co3+ cations.
