Xianyong Wu,Jessica J. Hong,Woochul Shin,Lu Ma,Tongchao Liu,Xuanxuan Bi,Yifei Yuan,Yitong Qi,T. Wesley Surta,Wenxi Huang,Joerg C. Neuefeind,Tianpin Wu,P. Alex Greaney,Jun Lu,Xiulei Ji +14 more
TL;DR: In this article, a Grotthuss proton conduction mechanism is used to transfer protons by concerted cleavage and formation of O-H bonds in a hydrogen-bonding network.
Journal ArticleDOI
In situ quantification of interphasial chemistry in Li-ion battery
Tongchao Liu,Tongchao Liu,Lingpiao Lin,Xuanxuan Bi,Lei-Lei Tian,Kai Yang,Jiajie Liu,Maofan Li,Zonghai Chen,Jun Lu,Khalil Amine,Khalil Amine,Kang Xu,Feng Pan +13 more
TL;DR: It is found that SEI formation starts at graphite edge sites with dimerization of solvated Li+ intercalation between graphite layers, and it is shown that this lithium salt can be re-oxidized, despite the general belief that an SEI is electrochemically inert and its formation irreversible.
Journal ArticleDOI
A disordered rock salt anode for fast-charging lithium-ion batteries
Haodong Liu,Zhuoying Zhu,Qizhang Yan,Sicen Yu,Xin He,Yan Chen,Rui Zhang,Lu Ma,Tongchao Liu,Matthew Li,Ruoqian Lin,Yiming Chen,Yejing Li,Xing Xing,Yoonjung Choi,Lucy Gao,Helen Cho,Ke An,Jun Feng,Robert Kostecki,Khalil Amine,Tianpin Wu,Jun Lu,Huolin L. Xin,Shyue Ping Ong,Ping Liu +25 more
TL;DR: It is reported that disordered rock salt can be used as a fast-charging anode that can reversibly cycle two lithium ions at an average voltage of about 0.6 volts versus a Li/Li+ reference electrode, alleviating a major safety concern (short-circuiting related to Li dendrite growth).
Journal ArticleDOI
Rejuvenating dead lithium supply in lithium metal anodes by iodine redox
Chengbin Jin,Tiefeng Liu,Ouwei Sheng,Matthew Li,Tongchao Liu,Yifei Yuan,Jianwei Nai,Zhijin Ju,Zhang Wenkui,Yujing Liu,Yao Wang,Zhan Lin,Jun Lu,Xinyong Tao +13 more
TL;DR: In this paper, a biochar capsule host for I3−/I− redox reaction is used to rejuvenate dead lithium to compensate for the lithium loss, and a full-cell using a very limited lithium metal anode exhibits an excellent lifespan of 1,000 cycles with a high Coulombic efficiency of 99.9%.
Journal ArticleDOI
Surface regulation enables high stability of single-crystal lithium-ion cathodes at high voltage.
Fang Zhang,Shuaifeng Lou,Shuang Li,Zhenjiang Yu,Qingsong Liu,Alvin Dai,Chuntian Cao,Michael F. Toney,Mingyuan Ge,Xianghui Xiao,Wah-Keat Lee,Yudong Yao,Junjing Deng,Tongchao Liu,Yiping Tang,Geping Yin,Jun Lu,Dong Su,Jiajun Wang +18 more
TL;DR: This work investigates the correlation of the surface structure, internal strain, and capacity deterioration by using operando X-ray spectroscopy imaging and nano-tomography and discovers that surface chemistry can significantly enhance the cyclic performance.
