Journal ArticleDOI
Enhanced Surface Interactions Enable Fast Li+ Conduction in Oxide/Polymer Composite Electrolyte.
Nan Wu,Nan Wu,Po-Hsiu Chien,Yumin Qian,Yutao Li,Henghui Xu,Nicholas S. Grundish,Biyi Xu,Haibo Jin,Yan-Yan Hu,Guihua Yu,John B. Goodenough +11 more
TL;DR: Li solid-state NMR results show an increase in Li + ions occupying the more mobile A2 environment in the composite electrolytes, which contributes to the more facile Li + transport.
Journal ArticleDOI
High-performance all-solid-state batteries enabled by salt bonding to perovskite in poly(ethylene oxide).
Henghui Xu,Po-Hsiu Chien,Jianjian Shi,Yutao Li,Nan Wu,Yuanyue Liu,Yan-Yan Hu,John B. Goodenough +7 more
TL;DR: It is reported that use of a perovskite Li+ electrolyte in place of the garnet ceramic provides an adequate Li+ conductivity at 25 °C without dendrite formation and a binding of the TFSI− anion of a LiTFSI [lithium bis(trifluoromethanesulfonyl)imide] salt to the polymer increases both the Li-ion conductivity and the Li+ transport number.
Journal ArticleDOI
Fast Li+ Conduction Mechanism and Interfacial Chemistry of a NASICON/Polymer Composite Electrolyte.
Nan Wu,Nan Wu,Po-Hsiu Chien,Yutao Li,Andrei Dolocan,Henghui Xu,Biyi Xu,Nicholas S. Grundish,Haibo Jin,Yan-Yan Hu,John B. Goodenough +10 more
TL;DR: The Li+ distribution and Li+ transport mechanism in a composite polymer electrolyte is identified by investigating a new solid poly(ethylene oxide) (PEO)-based NASICON-LiZr2(PO4)3 composite with 7Li relaxation time and 6Li→7Li trace-exchange NMR measurements.
Journal ArticleDOI
Interfacial Chemistry Enables Stable Cycling of All-Solid-State Li Metal Batteries at High Current Densities.
Biyi Xu,Xinyu Li,Chao Yang,Yutao Li,Nicholas S. Grundish,Po-Hsiu Chien,Kang Dong,Ingo Manke,Ruyi Fang,Nan Wu,Henghui Xu,Andrei Dolocan,John B. Goodenough +12 more
TL;DR: In this article, Mg(ClO4)2 is demonstrated to be an effective additive in the poly(ethylene oxide) (PEO)-based composite electrolyte to regulate Li+ ion transport and manipulate the Li metal/electrolyte interfacial performance.
Journal ArticleDOI
Li-ion transport in a representative ceramic–polymer–plasticizer composite electrolyte: Li7La3Zr2O12–polyethylene oxide–tetraethylene glycol dimethyl ether
TL;DR: In this article, a representative composite comprising a ceramic Li-ion conductor, garnet-type Li7La3Zr2O12 (LLZO), polyethylene oxide (PEO), and an additive, tetraethylene glycol dimethyl ether (TEGDME), has been clearly identified with high-resolution Li NMR.
