Journal ArticleDOI
Langmuir–Blodgett artificial solid-electrolyte interphases for practical lithium metal batteries
Mun Sek Kim,Ji-Hyun Ryu,Ji-Hyun Ryu,Deepika,Young Rok Lim,Young Rok Lim,In Wook Nah,Kwang-Ryeol Lee,Lynden A. Archer,Won Il Cho +9 more
TL;DR: In this paper, the physicochemical characteristics of Langmuir-Blodgett artificial SEIs (LBASEIs) created using phosphate-functionalized reduced graphene oxides are reported.
Journal ArticleDOI
Todorokite-type MnO2 as a zinc-ion intercalating material
TL;DR: In this paper, the structural and electrochemical properties of manganese dioxide with 3 × 3 tunnels bearing the crystallographic structure of the mineral todorokite were investigated for use as a new cathode material for zinc ion cells.
Journal ArticleDOI
Electrochemical properties of carbon-coated LiFePO4 cathode using graphite, carbon black, and acetylene black
Ho Chul Shin,Won Il Cho,Ho Jang +2 more
TL;DR: In this article, conductive carbon from three different carbon sources (graphite, carbon black, acetylene black) was used to investigate the electrochemical properties of LiFePO4 and found that the carbon-coated particles were smaller than the bare particles.
Journal ArticleDOI
Polysulfide dissolution control: the common ion effect.
TL;DR: A Li-sulfur cell with a high discharge capacity of over 1300 mAh g(-1) at a C/10 rate, and a controlled overcharge amount less than 1%, was manufactured by synthesizing a carbon-solfur nano-composite via a wet milling process, and suppressing polysulfide dissolution using an electrolyte with a highly concentrated lithium salt.
Journal ArticleDOI
In Situ Formation of Protective Coatings on Sulfur Cathodes in Lithium Batteries with LiFSI‐Based Organic Electrolytes
Hyea Kim,Feixiang Wu,Feixiang Wu,Jung Tae Lee,Naoki Nitta,Huan Ting Lin,Martin Oschatz,Won Il Cho,Stefan Kaskel,Oleg Borodin,Gleb Yushin +10 more
TL;DR: In this paper, it is demonstrated that electrochemical reduction of lithium bis(fluorosulfonyl)imide (LiFSI) based electrolytes at a potential close to the sulfur cathode operation forms in situ protective coating on both cathode and anode surfaces.
