Article Abstract
Electrolyte design has become ever more important to enhance the performance of lithium-ion batteries (LIBs). However, the flammability issue and high reactivity of the conventional electrolytes remain a major problem, especially when the LIBs are operated at high voltage and extreme temperatures. Herein, we design a novel non-flammable fluorinated ester electrolyte that enables high cycling stability in wide-temperature variations (e.g., -50 °C-60 °C) and superior power capability (fast charge rates up to 5.0 C) for the graphite||LiNi Co Mn O (NCM811) battery at high voltage (i.e., >4.3 V vs. Li/Li ). Moreover, this work sheds new light on the dynamic evolution and interaction among the Li , solvent, and anion at the molecular level. By elucidating the fundamental relationship between the Li solvation structure and electrochemical performance, we can facilitate the development of high-safety and high-energy-density batteries operating in harsh conditions.

Commercial lithium-ion batteries using organic solvent-based liquid electrolytes (LEs) face safety issues, including risks of fire and explosion. As a safer alternative, solid-state electrolytes are being extensively explored to replace these organic solvent-based LEs. Among various solid electrolyte options, polymer electrolytes offer advantages such as flexibility and ease of processing.

Dispersing iridium onto high-specific-surface-area supports is a widely adopted strategy to maximize iridium utilization in anode catalysts of proton exchange membrane water electrolysis (PEMWE). However, here we demonstrate that the overall cell performance, including initial efficiency and long-term stability, does not benefit from the typical high specific surface area of catalyst supports. The conventional understanding that high iridium utilization on high-specific-surface-area supports increases activity holds only in aqueous electrolytes, while under the typical working conditions of PEMWE, the mass transport within the anode catalyst layers plays a more significant role in the overall performance.

This study pioneers the use of organic nitrate C(NH)NO as an electrolyte additive in lithium metal batteries (LMBs). C(NH)NO can effectively construct a high-quality solid electrolyte interphase (SEI) on the lithium metal anode, thereby enabling dendrite-free and uniform spherical lithium (Li) deposition.

In this study, we unveil a critical function of anions in tailoring the interfacial water coordination environment and electronic structure at the Zn-electrolyte interface. These features thermodynamically hinder water-induced parasitic reactions, enabling highly reversible Zn plating/stripping. And the optimal electrolyte supports high-mass-loading applications in Zn-MnO batteries.

Developing solid electrolytes with high ionic conductivity, a high voltage window, low flammability, and excellent interface compatibilities with both the anode and cathode for lithium-metal batteries is still a great challenge but highly desirable. Herein, we achieve this target through an in situ copolymerization of vinyl ethylene carbonate (VEC) together with acrylonitrile (AN) under fitting ratios inside a porous polyacrylonitrile (PAN) fiber membrane doped with flame-retardant decabromodiphenyl ethane (DBDPE) molecules. The received fiber-reinforced polycarbonate-based composite electrolyte with an ultrathin thickness of 13 μm exhibits good internal interfacial compatibility because of the same AN structure and superior flame-retardant performance due to the doped DBDPE molecules.
