Abstract The lithium (Li) metal battery (LMB) is one of the most promising candidates for next‐generation energy storage systems. However, it still a significant challenge to operate LMBs with high voltage cathodes under rate conditions. In this work, an LMB using nickel‐rich layered cathode LiNi 0.76 Mn 0.14 Co 0.10 O 2 (NMC76) and optimized electrolyte [0.6 m bis(trifluoromethanesulfonyl)imide + 0.4 bis(oxalato)borate 0.05 LiPF 6 dissolved in ethylene carbonate ethyl methyl (4:6 by...
Tuning hierarchical micro/nanostructure of electrode materials is a sought-after means to reinforce their electrochemical performance in the energy storage field. Herein, we introduce type mesoporous Li[Li0.2Ni0.2Mn0.6]O2 microsphere composed nanoparticles synthesized via an ice templating combined coprecipitation strategy. It low-cost, eco-friendly, and easily operated method using as template control material with homogeneous morphology rich porous channels. The as-prepared exhibits...
Conventional electrolytes made by mixing simple Mg2+ salts and aprotic solvents, analogous to those in Li-ion batteries, are incompatible with Mg anodes because metal readily reacts such electrolytes, producing a passivation layer that blocks transport. Here, we report that, through tuning conventional electrolyte—Mg(TFSI)2 (TFSI– is N(SO2CF3)2–)—with an Mg(BH4)2 cosalt, highly reversible plating/stripping high Coulombic efficiency achieved neutralizing the first solvation shell of cationic...
Superconcentrated aqueous electrolytes ("water-in-salt" electrolytes, or WiSEs) enable various battery chemistries beyond the voltage limits imposed by Pourbaix diagram of water. However, their detailed structural and transport properties remain unexplored could be better understood through added studies. Here, we report on our observations strong acidity (pH 2.4) induced lithium bis(trifluoromethane sulfonyl)imide (LiTFSI) at superconcentration (at 20 mol/kg). Multiple nuclear magnetic...

Traditional polyolefin separators used in lithium-ion batteries (LIBs) are seriously limited by the issues of inferior security and poor electrolyte wettability. Most very promising candidate based on heat-resistant polymers are, however, inherently difficult to process. Herein, a unique sulfonated aromatic heterocyclic polymer, lithiated poly(diphenyl ether oxadiazole) sulfonate (Li-SPEOD), was synthesized through simple one-pot method further electrospun act as novel separator...
One of the main impediments faced for predicting emergent properties a multivalent electrolyte (such as conductivity and electrochemical stability) is lack quantitative analysis ion–ion ion–solvent interactions, which manifest in solvation structures dynamics. In particular, role interactions still unclear cases where strong electric field from cations can influence intramolecular rotations conformal structural evolution (i.e., solvent rearrangement process) low permittivity organic...
Ionic liquid gel polymer electrolytes (ILGPEs) based on a micro-porous membrane were designed to both improve the battery safety and maintain rapid migration channels for Li<sup>+</sup>.
Mass spectrometry-based targeted proteomics (e.g., selected reaction monitoring, SRM) is emerging as an attractive alternative to immunoassays for protein quantification. Recently we have made significant progress in SRM sensitivity enabling quantification of low nanograms per milliliter sub-naograms level proteins nondepleted human blood plasma/serum without affinity enrichment. However, precise extremely abundance ≤ 100 pg/mL plasma/serum) using approaches still remains challenging,...
Mg batteries have been proposed as potential alternatives to lithium-ion because of their lower cost, higher safety, and enhanced charge density. However, the metal readily oxidizes when exposed an oxidizer form a thin MgO passivation surface layer that blocks transport Mg2+ across solid electrode–electrolyte interface (SEI). In this work, adsorption thermal decomposition diglyme (G2) electrolytes containing Mg(TFSI)2 in G2 on 10 nm-sized particles are evaluated by combination situ 13C...

Polymer electrolytes based on poly(ethylene oxide) (PEO) have been extensively investigated for battery applications due to their excellent flexibility, chemical stability, and ease of processing. One major issue with the PEO-based is insufficient ionic conductivity. In this work, we incorporated 1-butyl-1-methylpyrrolidinium bis(fluorosulfonyl)imide (PY14FSI) into P(EO)20NaFSI, which significantly increases amorphous phase, promotes interactions between NaFSI ether oxygen in PEO, enables...
