Nano-Micro Letters, Год журнала: 2022, Номер 14(1)

Опубликована: Апрель 6, 2022

Aqueous zinc metal batteries are noted for their cost-effectiveness, safety and environmental friendliness. However, the water-induced notorious issues such as continuous electrolyte decomposition uneven Zn electrochemical deposition remarkably restrict development of long-life batteries. In this study, zwitterionic sulfobetaine is introduced to copolymerize with acrylamide in perchlorate (Zn(ClO4)2) solution. The designed gel framework hydrophilic charged groups can firmly anchor water molecules construct ion migration channels accelerate transport. situ generated hybrid interface, which composed organic functionalized outer layer inorganic Cl- containing inner layer, synergically lower mass transfer overpotential, reduce water-related side reactions lead uniform deposition. Such a novel configuration enables Zn//Zn cells an ultra-long cycling life over 3000 h low polarization potential (~ 0.03 V) Zn//Cu high Coulombic efficiency 99.18% 1000 cycles. Full matched MnO2 cathodes delivered laudable stability impressive shelving ability. Besides, flexible quasi-solid-state equipped anti-vandalism ability (such cutting, hammering soaking) successfully power LED simultaneously. safe, processable durable hydrogel promises significant application electronic devices.

Boosting Cathode Activity and Anode Stability of Zn‐S Batteries in Aqueous Media Through Cosolvent‐Catalyst Synergy

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(42)

Опубликована: Сен. 3, 2022

Aqueous Zn-S battery with high energy density represents a promising large-scale storage technology, but its application is severely hindered by the poor reversibility of both S cathode and Zn anode. Herein, we develop "cocktail optimized" electrolyte containing tetraglyme (G4) water as co-solvents I2 additive. The G4-I2 synergy could activate efficient polar I3- /I- catalyst couple shield from water, thus facilitating conversion kinetics suppressing interfacial side reactions. Simultaneously, it stabilize anode forming an organic-inorganic interphase upon cycling. With boosted electrodes reversibility, cell delivers capacity 775 mAh g-1 at 2 A , retains over 70 % after 600 cycles 4 . advances can also be readily generalized to other ethers/water hybrid electrolytes, showing universality design strategy.

Rational Design of High-Performance PEO/Ceramic Composite Solid Electrolytes for Lithium Metal Batteries

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Март 31, 2023

Composite solid electrolytes (CSEs) with poly(ethylene oxide) (PEO) have become fairly prevalent for fabricating high-performance solid-state lithium metal batteries due to their high Li+ solvating capability, flexible processability and low cost. However, unsatisfactory room-temperature ionic conductivity, weak interfacial compatibility uncontrollable Li dendrite growth seriously hinder progress. Enormous efforts been devoted combining PEO ceramics either as fillers or major matrix the rational design of two-phase architecture, spatial distribution content, which is anticipated hold key increasing conductivity resolving within CSEs between CSEs/electrodes. Unfortunately, a comprehensive review exclusively discussing design, preparation application PEO/ceramic-based largely lacking, in spite tremendous reviews dealing broad spectrum polymers ceramics. Consequently, this targets recent advances CSEs, starting brief introduction, followed by conduction mechanism, methods, then an emphasis on compatibility. Afterward, applications transition oxides sulfur cathodes are summarized. Finally, summary outlook existing challenges future research directions proposed.

Abstract The upsurging demand for electric vehicles and the rapid consumption of lithium‐ion batteries (LIBs) calls LIBs to possess high energy density resource sustainability. former requires usage electroactive materials with capacity maximum amount within fixed electrode volume. latter essentially creates a closed‐loop circulation scenario materials. In all aspects, binders are practical significance in bonding materials, maintaining integrity detaching slurry from current collector. Currently, key role enhancing electrochemical behavior sustainable high‐capacity has been recognized. Meanwhile, that designed easy cost‐effective recycling gradually reported. Herein, recently developed hold promises establishing high‐energy‐density summarized. binder facilitating separation first highlighted. Subsequently, special attention is paid conductive binders, contributing less battery chemistries higher electrode. Additionally, progress emerging also reviewed.

The new-generation lithium metal batteries require polymer electrolytes with high ionic conductivity and mechanical properties. However, the performance of is severely influenced by bond formation between functional groups ions (Li+), which has barely been considered in past. Herein, a enriched gel (PAEV) elaborately designed copolymerizing 4-acryloylmorpholine (ACMO) 1-vinyl-3-ethyl imidazolium bis(trifluoromethylsulfonyl)imide ([VEIM][TFSI]) 1-ethyl-3-methyl ([EMIM][TFSI]) presence LiFSI. bonds formed LiFSI carbonyl PACMO can be regulated Li+ coordination number, further weakened hydrogen [EMIM][TFSI] poly[VEIM][TFSI], to effectively render electrolyte adjustable tunable property. In addition, environment Li+, LiF Li3N layer uniformly on Li surface facilitate nucleation deposition. As consequence, PAEV confers Li/LiFePO4 (LFP) battery capacity 124 mA h g-1 at 1 C under 25 °C, 152 50 °C. This work promote development via manipulation.

Опубликована: Авг. 2, 2023

Lithium fluoride (LiF) at the solid electrolyte interface (SEI) contributes to stable operation of polymer-based solid-state lithium metal batteries. Currently, most methods for constructing SEI are based on design polar groups fillers. However, mechanism behind how steric hindrance fillers impacts LiF formation remains unclear. This study synthesizes three kinds porous polyacetal amides (PAN-X, X=NH2 , NH-CH3 N-(CH3 )2 ) with varying hindrances by regulating number methyl substitutions nitrogen atoms reaction monomer, which incorporated into polymer composite electrolytes, investigate regulation content in SEI. The results show that bis(trifluoromethanesulfonyl)imide (TFSI- will compete charge without effect, while excessive hinders interaction between TFSI- and groups, reducing acquisition. Only when one hydrogen atom amino group is replaced a group, from prevents capturing direction, thereby facilitating transfer separate promoting maximum formation. work provides novel perspective LiF-rich
