Synthesis of functionalized 3D hierarchical porous carbon for high-performance supercapacitors
Long Qie,Wei-Min Chen,Henghui Xu,Xiaoqin Xiong,Yan Jiang,Feng Zou,Xianluo Hu,Ying Xin,Zhaoliang Zhang,Yunhui Huang +9 more
TL;DR: In this paper, a functionalized three-dimensional hierarchical porous carbon (THPC) is prepared via a facile modified chemical activation route with polypyrrole microsheets as precursor and KOH as activating agent.
Journal ArticleDOI
Flexible Asymmetric Micro‐Supercapacitors Based on Bi2O3 and MnO2 Nanoflowers: Larger Areal Mass Promises Higher Energy Density
TL;DR: In this paper, a flexible asymmetric supercapacitor with high energy density is designed and fabricated using flower-like Bi2O3 and MnO2 grown on carbon nanofiber (CNF) paper as the negative and positive electrodes, respectively.
Journal ArticleDOI
Hybrid Polymer/Garnet Electrolyte with a Small Interfacial Resistance for Lithium-Ion Batteries.
Yutao Li,Biyi Xu,Henghui Xu,Huanan Duan,Xujie Lü,Sen Xin,Weidong Zhou,Leigang Xue,Gengtao Fu,Arumugam Manthiram,John B. Goodenough +10 more
TL;DR: LiF is introduced to garnet Li6.5 La3 Zr2 O12 (LLZT) to increase the stability of the garnet electrolyte against moist air and shows a small interfacial resistance with Li metal, a solid polymer electrolyte, and organic-liquid electrolytes.
Journal ArticleDOI
Garnet Electrolyte with an Ultralow Interfacial Resistance for Li-Metal Batteries.
Yutao Li,Xi Chen,Andrei Dolocan,Zhiming Cui,Sen Xin,Leigang Xue,Henghui Xu,Kyusung Park,John B. Goodenough +8 more
TL;DR: A simple method to remove Li2CO3 and the protons in the garnet framework is introduced by reacting garnet with carbon at 700 °C and the amount of the Li-Al-O glass phase with a low Li-ion conductivity in the grain boundary on the Garnet surface was reduced.
Journal ArticleDOI
Li3N-Modified Garnet Electrolyte for All-Solid-State Lithium Metal Batteries Operated at 40 °C
TL;DR: This study presents an effective strategy to reduce significantly the interfacial resistance by replacing Li2CO3 with Li ion conducting Li3N, which exhibits an ultralow overpotential and stable plating/stripping cyclability without lithium dendrite growth at room temperature.
