Abstract In electrochemical devices, such as batteries, traditional electric double layer (EDL) theory holds that cations in the cathode/electrolyte interface will be repelled during charging, leaving a large amount of free solvents. This promotes continuous anodic decomposition electrolyte, leading to limited operation voltage and cycle life devices. this work, we design new EDL structure with adaptive passivating properties. It is enabled by adding functional anionic additives which can...
In battery electrolyte design principles, tuning Li+ solvation structure is an effective way to connect chemistry with interfacial chemistry. Although recent proposed strategies are able improve cyclability, a comprehensive strategy for remains imperative. Here, we report by utilizing molecular steric effect create "bulky coordinating" structure. Based on this strategy, the designed generates inorganic-rich solid interphase (SEI) and cathode-electrolyte (CEI), leading excellent compatibility...
Improved durability, enhanced interfacial stability, and room temperature applicability are desirable properties for all-solid-state lithium metal batteries (ASSLMBs), yet these desired rarely achieved simultaneously. Here, in this work, it is noticed that the huge resistance at Li metal/electrolyte interface dominantly impeded normal cycling of ASSLMBs especially around (<30 °C). Accordingly, a supramolecular polymer ion conductor (SPC) with "weak solvation" Li+ was prepared. Benefiting...
Donor number (DN) serves as a metric for describing the basicity of solvent or anion and delineates tendency to donate electrons electron acceptors. In this review, we...
Solid polymer electrolytes suffer from the polymer-dominated Li + solvation structure, causing unstable electrolyte/electrode interphases and deteriorated battery performance. Here, we design a class of selectively fluorinated aromatic lithium salts (SFALS) as single conducting to regulate structure interfacial chemistry for all-solid-state metal batteries. By tuning anionic -polyether coupling is weakened, -anion coordination enhanced. The hydrogen bonding between SFALS matrix induces...
A fluorinated amide molecule with two functional segments, namely, an group a high donor number to bind lithium ions and fluorine chain expel carbonate solvents mediate the formation of LiF, was designed regulate interfacial chemistry. As expected, additive preferably appears in first solvation sheath is electrochemically reduced on anode, thus inorganic-rich solid electrolyte interphase generated. The morphology deposited metal evolves from brittle dendrites into granular shape....
Li metal is regarded as the most promising battery anode to boost energy density. However, being faced with hostile compatibility between and traditional carbonate electrolyte, its large-scale industrialization has been in a distressing circumstance due severe dendrite growth caused by unsatisfying solid electrolyte interphase (SEI). With this regard, accurate control over composition of SEI urgently desired tackle electrochemical mechanical instability at electrolyte/anode interface....
Ultrahigh-voltage lithium metal batteries based on cobalt-free LiNi0.5Mn1.5O4 (LNMO) cathode (5 V-class, vs. Li+/Li) and anode (-3.04 V the standard hydrogen electrode) have attracted extensive attention in...
Abstract The electrolytes for lithium metal batteries (LMBs) are plagued by a low Li + transference number (T ) of conventional salts and inability to form stable solid electrolyte interphase (SEI). Here, we synthesized self‐folded salt, 2‐[2‐(2‐methoxy ethoxy)ethoxy]ethanesulfonyl(trifluoromethanesulfonyl) imide (LiETFSI), comparatively studied with its structure analogue, 1,1,1‐trifluoro‐N‐[2‐[2‐(2‐methoxyethoxy)ethoxy)]ethyl]methanesulfonamide (LiFEA). special anion chemistry imparts the...

Ideal high-temperature lithium metal battery (LMB) electrolytes should have good thermal stability and compatibility with highly reactive cathodes/anodes. Yet, conventional liquid usually show severe degradation substantial safety risks...
Solid polymer electrolytes (SPEs) are the key components for all-solid-state lithium metal batteries with high energy density and intrinsic safety. However, low ion transference number (t+) of a conventional SPE its unstable electrolyte/electrode interface cannot guarantee long-term stable operation. Herein, asymmetric trihalogenated aromatic salts, i.e., (3,4,5-trifluorobenzenesulfonyl)(trifluoromethanesulfonyl)imide (LiFFF)...
The low reversibility of Li deposition/stripping in conventional carbonate electrolytes hinders the development lithium metal batteries. Herein, we proposed a combination solvents with moderate donor number (DN) and LiNO3 as sole salt, which has rarely been attempted due to its solubility or dissociation degree common solvents. It is found that DN value highly correlated deposition behavior when applied salt. behaves like quasi-concentrated electrolyte even at concentration, while neither...

Potassium-ion batteries (PIBs) are deemed as one of the most promising energy storage systems due to their high density and low cost. However, commercial application is far away from satisfactory because limited suitable electrode materials. Herein, core-shell structured WSe2 @N-doped C nanotubes rationally designed synthesized via selenizing WO3 @ polypyrrole for first time. The large interlayer spacing can facilitate intercalation/deintercalation K+ . Meanwhile, nanotube provides favorable...
Poly(ethylene oxide) (PEO)-based solid electrolyte suffers from limited anodic stability and an intrinsic flammable issue, hindering the achievement of high energy density safe all-solid-state lithium batteries. Herein, we surprisingly found out that a bromine-rich additive, decabromodiphenyl ethane (DBDPE), could be preferably oxidized at elevated voltage decompose to bromide potential followed by inducing organic-rich cathode/electrolyte interphase (CEI) on NCM811 surface, enabling both...
