Heterogeneous Catalysis for Lithium–Sulfur Batteries: Enhanced Rate Performance by Promoting Polysulfide Fragmentations
Tae-Gyung Jeong,Dong Shin Choi,Hannah Song,Jihwan Choi,Shin-Ae Park,Si Hyoung Oh,Heejin Kim,Yousung Jung,Yong-Tae Kim +8 more
TL;DR: In this paper, a more effective approach outperforming this conventional one: a heterogeneous catalysis to promote polysulfide fragmentations was reported, exhibiting a discharge capacity of 700 mAh/g/1 at a scan rate of 5C.
Journal ArticleDOI
Stabilization of Oxygen-deficient Structure for Conducting Li4Ti5O12-δ by Molybdenum Doping in a Reducing Atmosphere
Hannah Song,Tae-Gyung Jeong,Young Hoon Moon,Ho-Hwan Chun,Kyung Yoon Chung,Hyung Sun Kim,Byung Won Cho,Yong-Tae Kim +7 more
TL;DR: Using this simple method, a marked increase in electronic conductivity was achieved, in addition to an extremely high rate capability, with no performance deterioration over time.
Journal ArticleDOI
Free standing acetylene black mesh to capture dissolved polysulfide in lithium sulfur batteries
TL;DR: A cheap and simple approach to solve the polysulfide dissolution problem in lithium sulfur batteries was reported, and it was interestingly revealed that a simple insertion of acetylene black mesh enabled us to obtain the capacity of 1491 mA h g(-1) at initial discharge and 1062 m a h g (-1) after 50 cycles.
Journal ArticleDOI
The cycling performances of lithium–sulfur batteries in TEGDME/DOL containing LiNO3 additive
TL;DR: In this paper, the cycling performance of lithium-sulfur batteries in binary electrolytes based on tetra(ethylene glycol)dimethyl ether (TEGDME) and 1,3-dioxolane (DOL) with lithium nitrate (LiNO3) additive was investigated.
Journal ArticleDOI
Tungsten Carbide as a Highly Efficient Catalyst for Polysulfide Fragmentations in Li–S Batteries
Jihwan Choi,Jihwan Choi,Tae-Gyung Jeong,Tae-Gyung Jeong,Byung Won Cho,Yousung Jung,Si Hyoung Oh,Yong-Tae Kim +7 more
TL;DR: In this article, the authors show that tungsten carbide acts as a superb anchoring material for the long chain polysulfide and also promotes the dissociation of short-chain poly sulfide during the electroreduction process.
