Customized Solvation Structures for Long-Term Stable Lithium Metal Batteries.

Lithium metal batteries (LMBs) suffer from severe lithium dendrite growth and side reactions in conventional carbonate electrolytes, which are characterized by low coulombic efficiency and poor cycling stability, and electrolyte engineering is an effective method for increasing the reversibility of lithium anodes. Herein, the solubility of lithium nitrate (LiNO), which is almost insoluble in carbonate electrolyte, is improved by adding zinc trifluoroacetate (Zn(TFA)), and a competitive solvation structure is constructed, forming an anion-enriched Li solvation structure, which is conducive to the formation of stable SEI and effectively inhibits adverse side reactions. The lithium metal anode exhibits uniform lithium deposition and extended cycle life, with high reversibility over plating/stripping for 640 h.

Electrical Double Layer and In Situ Polymerization SEI Enables High Reversible Zinc Metal Anode.

Aqueous zinc-ion batteries (AZIBs) stand out among new energy storage devices due to their excellent safety and environmental friendliness. However, the formation of dendrites and side reactions on the zinc metal anode during cycling have become the major obstacles to their commercialization. This study innovatively selected Sodium 4-vinylbenzenesulfonate (VBS) as a multifunctional electrolyte additive to address the issues.

Nucleolar Dominance in a Tetraploidy Hybrid Lineage Derived From red var. () × ().

Nucleolar dominance is related to the expression of genes inherited from one progenitor due to the silencing of the other progenitor's genes. To investigate nucleolar dominance associated with tetraploidization, we analyzed the changes regarding the genetic traits and expression of genes in tetraploidy hybrid lineage including F allotetraploids (4n = 148) and F autotetraploids (4n = 200) derived from the distant hybridization of red var. (2n = 100) () × (2n = 48) ().
