Application-Based Prospects for Dual-Ion Batteries
ChemSusChem. 2022 Aug 23. doi: 10.1002/cssc.202201245. Online ahead of print.ABSTRACTDual-ion batteries (DIBs) exhibit a distinct set of performance advantages and disadvantages due to their unique storage mechanism. However, the current cyclability/energy density tradeoffs of anion storage paired with the intrinsic required electrolyte loadings of conventional DIBs preclude their widespread adoption as an alternative to lithium-ion batteries (LIBs). Despite this, their reduced desolvation penalty and low-cost electrode materials may warrant their employment for low-temperature and/or grid storage applications. To expand b...

An integrated design of electrodes for flexible dual-ion batteries
ChemSusChem. 2022 Jul 21. doi: 10.1002/cssc.202201252. Online ahead of print.ABSTRACTDue to the widespread employment of carbon materials in novel dual-ion batteries (DIBs) with high energy density, they possess the potential for large-scale energy storage and are inexpensive and environmentally friendly. However, drawbacks such as Al current collector corrosion and significant self-weight, as well as lithium metal abuse and poor deposition reversibility in lithium-graphite DIBs (Li-G DIBs), impair the energy density and cycle performance of Li-G DIBs, severely limiting their application potential. Therefore, an integrated...

Chemo- and regioselective anionic Fries rearrangement promoted by lithium amides under aerobic conditions in sustainable reaction media
Chemistry. 2022 Apr 26. doi: 10.1002/chem.202201154. Online ahead of print.ABSTRACTA straightforward and efficient protocol to promote the metalation/anionic Fries rearrangements of O-aryl carbamates, using for the first time a lithium amide as metalating agent under aerobic/ambient-friendly reaction conditions, is reported. This approach enables the sustainable preparation of salicylamide derivatives with high levels of chemoselectivity within ultrafast reaction times, working at room temperature in the presence of air/moisture, and using the environmentally responsive cyclopentyl methyl ether as a solvent. Furthermore, t...

Double ionic-electronic transfer interface layers for all solid-state lithium batteries
Angew Chem Int Ed Engl. 2021 May 20. doi: 10.1002/anie.202104183. Online ahead of print.ABSTRACTThe interface between electrode and solid electrolyte concerning the high resistance and poor stability as well as poor compatibility against the Li+ migration is impeding the large-scale employment of all solid-state lithium batteries. Here, we report double ionic-electronic transfer interface layers at electrode-electrolyte interfaces by in situ polymerization of 2, 2'-bithiophene in polyethylene oxide (PEO) electrolyte. For all solid-state LiFePO4||PT-PEO-PT||Li cells, the formation of conductive polythiophene (PT) layer at c...

Atomic Tungsten on Graphene with Unique Coordination Enabling Kinetically Boosted Lithium-sulfur Batteries
Angew Chem Int Ed Engl. 2021 Apr 26. doi: 10.1002/anie.202104053. Online ahead of print.ABSTRACTThe employment of catalytic materials is regarded as the most desirable strategy to cope with sluggish kinetics of lithium polysulfides (LiPSs) transformation and severe shuttle effect within lithium-sulfur batteries (LSBs). Single-atom catalysts (SACs) with 100% atom-utilization possess competitive advantages to serve as both anchoring and electrocatalytic centers for LiPSs. However, it's still a great challenge due to the insufficiency of facile synthetic strategy and ambiguity of the structure-property relationships. Herein, ...

Lithium halide ion-pair recognition with halogen bonding and chalcogen bonding heteroditopic macrocycles
Chem Commun (Camb). 2021 Apr 20. doi: 10.1039/d1cc01287h. Online ahead of print.ABSTRACTA series of halogen bonding and chalcogen bonding phenanthroline containing heteroditopic macrocyclic receptors exhibit cooperative recognition of lithium halide (LiX) ion-pairs. Quantitative 1H NMR ion-pair titration experiments in CDCl3 : CD3CN (1 : 1, v/v) reveal a co-bound lithium cation switches on halide anion binding, most notably with the halogen bonding host system. The employment of bis- iodo- and telluromethyl-triazole sigma-hole donor motifs endows contrasting halide anion selectivity and binding affinity, with the halogen b...
