TL;DR: The “cationic potential” is introduced that captures the key interactions of layered materials and makes it possible to predict the stacking structures and is demonstrated through the rational design and preparation of layered electrode materials with improved performance.

TL;DR: An overview of Na-ion SSEs is first outlined according to the classification of solid polymer electrolytes, composite polymer electrolyte, inorganic solid electrolytes and the current challenges and critical perspectives for the potential development of solid-state sodium batteries are discussed in detail as mentioned in this paper.

TL;DR: In this article, a 3D flexible carbon (C) felt was used as a host for prestoring Na via a melt infusion strategy, through which a Na/C composite anode was obtained.

TL;DR: In this paper, a pyrolyzed anthracite (PA) anode material with superior low cost and high safety through one simple carbonization process is reported, which can meet the requirements for practical applications and pave the way for the industrial production of low-cost and high-safety sodium-ion batteries for large scale electrical energy storage.

TL;DR: In this paper, a hierarchical poly (ionic liquid)-based solid electrolyte (HPILSE) for high-safety Li-ion and Na-ion batteries is reported, which is fabricated via in situ polymerizing 1,4-bis[3-(2-acryloyloxyethyl)imidazolium-1-yl]butane bis[bis(trifluoromethanesulfonyl)imide] (C1-4TFSI) monomer in 1-ethyl-3-methylimidaxolium
