Halogen-Bonding Nanoarchitectonics in Supramolecular Plasticizers for Breaking the Trade-Off between Ion Transport and Mechanical Strength of Polymer Electrolytes for High-Voltage Li-Metal Batteries

ACS Nano (2024)

Jieqing Shen Wensheng Tian Shuohan Liu Pan Hui Cheng Yang

The low ionic conductivity of poly(ethylene oxide) (PEO)-based polymer electrolytes at room temperature impedes their practical applications. The addition of a plasticizer into polymer electrolytes could significantly promote ion transport while inevitably decreasing their mechanical strength. Herein, we report a supramolecular plasticizer (SMP) to break the trade-off effect between ionic conductivity and mechanical properties in PEO-based polymer electrolytes. Accordingly, the SMP is constructed by tetraethylene glycol dimethyl ether (G4) and SbF

Enlarging potential window and enhancing stability of poly(ethylene oxide)-based composite solid electrolyte via succinonitrile additive for advanced solid lithium batteries

Functional Materials Letters (2021)

Tingfang Yan Lei Zhu Yongmin Wu Jingxiong Gao Wensheng Tian

Solid polymer electrolytes such as poly(ethylene oxide) (PEO) are desirable in lithium batteries due to their high safety and excellent flexibility. However, low ionic conductivity and electrochemical stability of PEO hamper their applications. In this work, succinonitrile (SN) is added to the composite solid electrolyte (CSE) composed of PEO matrix and [Formula: see text]La 3 [Formula: see text][Formula: see text][Formula: see text] filler to improve its ionic conductivity and electrochemical stability, thereby matching with ternary cathode materials. The results reveal that the ionic conductivity of CSE at 55 ∘ C can be increased by more than one order of magnitude with the addition of SN. And the CSE membrane containing 6 wt.% SN (CSE-6) exhibits the best electrochemical stability, which has improved the electrochemical window from 4.83 to 5.26 V. Compared with blank sample without the additive, the specific capacity of [Formula: see text][Formula: see text][Formula: see text]O 2 /CSE-6/Li is increased from 15.6 to 154 mAh ⋅ g[Formula: see text], and exhibits relatively optimal cyclic stability in a range of solid-state batteries with different SN contents. It is expected that the results of this study will provide a reference for the application of PEO-based CSEs in high-voltage solid lithium batteries.

Eliminating Concentration Polarization with Gradient Lithiophilic Sites Towards High Performance Lithium Metal Anodes Under Low N/P Ratio

Zichun Xiao Duzhao Han Yu Fu Keyu Xie Wensheng Tian

Three-dimensional (3D) skeletons have been extensively explored for effectively inhibiting dendrite growth and mitigating the volume change of lithium (Li). However, the ionic concentration polarization ascribing to the different ionic transmission distance in 3D skeletons inevitably induce the uneven growth of Li, leading to preferential deposition of Li in the top region rather than a spatially ordered manner from bottom-up. This uncontrollable deposition will deviate the original guidance of 3D skeleton. In this study, a gradient lithiophilic carbon fibers (CFs) is designed and constructed by regulating the distribution of ZnO nucleation sites (CFs@GZnO skeleton) to achieve a spatially ordered Li plating/stripping process. Benefiting from this gradient lithiophilic design, the non-uniform ionic polarization within the 3D skeleton is mitigated, effectively inducing Li plating/stripping in a spatially ordered manner. Full cell with an ultrahigh mass loading NCM811 cathode (38 mg cm-2) and Li-CFs@GZnO (CFs@GZnO skeleton pre-plated with Li) anode under a low negative to positive (N/P) ratio of 2 achieved a lifespan of 100 cycles with a capacity fading of only 0.083% per cycle. Thus, the strategy of inducing gradient lithiophilic sites into 3D skeletons may provide a new avenue to construct a dendrite-free and stable anode for high energy density LMBs.
