2023年10月16日 · Here, we propose a biocompatible hydrogel electrolyte by utilising hyaluronic acid, which contains ample hydrophilic functional groups. The gel-based electrolyte offers excellent anti-corrosion...

2022年12月28日 · As proof of concept, high-voltage lithium manganese oxide (LMO) cathode was coupled with Zn metal anode in the hybrid electrolyte for full cell testing. As a result, the Zn‖LMO batteries were successfully cycled for more than 400 cycles with a high average voltage of 1.85 V and an excellent average Coulombic efficiency of 99.7%.

2023年7月6日 · Here, we propose that thermodynamic nucleation overpotential of Zn deposition can be boosted through complexing agent and select sodium L-tartrate (Na-L) as example. Theoretical and experimental characterization reveals L-tartrate anion can partially replace H 2 O in the solvation sheath of Zn 2+, increasing de-solvation energy.

采用PZLUE共晶凝胶组装准固态Zn//LMO电池， 柔性电池 点亮了28个并联的led，并且可以在弯曲和穿戴条件下正常工作(图5i)，显示了作为柔性电源应用的巨大潜力。

2023年11月1日 · Here, a robust heterointerface composed of 0D metal nanodots and 2D metal carbide nanosheets with triple synergistic effects is designed to manipulate interfacial chemistry for anode-free Zn batteries. An interface of in situ anchoring ultrafine Sn nanodots on Na + decorated MXene nanosheets is used as a model.

2021年2月15日 · Zn/LiFePO 4 (LFP) and Zn/LMO cells using this electrolyte offer superior performance compared to those employing dilute electrolytes because of the reduced water activity and the unique solvation structure.

2025年2月19日 · Among the doped samples, LiMn 1.98 Zn 0.02 O 4 (LMO-0.02Zn) exhibited the best electrochemical performance. It maintained a capacity retention of 85.01% after 300 cycles at 1C, with a specific capacity reaching 97.94 mAh·g −1. In contrast, the undoped LiMn 2 O 4 merely exhibited a capacity retention of 69.26%.

2019年3月1日 · Here, we report a new “water-in-deep eutectic solvent (water-in-DES)” electrolyte (~30 mol.% H2O in a eutectic mixture of urea/LiTFSI/Zn (TFSI)2; TFSI, bis (trifluoromethanesulfonyl)imide), in which all water molecules participate in DES's internal interaction (H-bonding and coordinating) network, leading to …

Herein, we investigate the performance of an aqueous Zn‖LiMn (Zn‖LMO) hybrid battery with a bi-salt (ZnSO and Li) electrolyte modified with a low dosage of poly (ethylene glycol) (PEG200) and MnSO. The PEG additive effectively inhibits water decomposition, mitigates Zn metal corrosion, and promotes the in-plane growth of hexagonal Zn flakes.

从周期表中选择了九种阳离子元素（Mg、Al、Ti、V、Cr、Fe、Ni、Cu、Zn），并分别通过替换四个Mn原子将它们单独掺入1×1×2超胞的LMO晶格中（分别称为Mg-LMO、Al-LMO、Ti-LMO、V-LMO、Cr-LMO、Fe-LMO、Ni-LMO、Cu-LMO、Zn-LMO）。 研究发现， 引入Cu、Mg、Fe、Zn和Ni阳离子导致M-O键长和Li-O距离的最大增加，同时Mn-O键长减少幅度最大。 从理论上讲，增加的Li-O距离可以减弱Li和O之间的静电相互作用，从而促进Li+扩散并稳定三维扩散通道 …
