Journal ArticleDOI
A study on the charge-discharge mechanism of Co3O4 as an anode for the Li ion secondary battery
Yong-Mook Kang,Min-Sang Song,Jin-Ho Kim,Hyun-seok Kim,Min-Sik Park,Jai-Young Lee,Hua-Kun Liu,Shi Xue Dou +7 more
TL;DR: In this paper, a cyclic voltammogram of a Li 2 O−Co mixture was used to detect the formation and decomposition of a transition metal oxide. And the results showed that the oxidation and reduction in the CV of the CV correspond to the decomposition and formation of Li 2 o−Co, and that the catalytic effect of the transition metal must be one of the main causes that make Li O form or decompose repeatedly.
Journal ArticleDOI
Effect of Multiwalled Carbon Nanotubes on Electrochemical Properties of Lithium/Sulfur Rechargeable Batteries
TL;DR: In this paper, multiwalled carbon nanotubes (MWNTs) were prepared by thermal chemical vapor deposition as an inactive additive material for elemental sulfur positive electrodes for lithium/sulfur rechargeable batteries.
Journal ArticleDOI
Effects of Nanosized Adsorbing Material on Electrochemical Properties of Sulfur Cathodes for Li/S Secondary Batteries
Min-Sang Song,Sang-Cheol Han,Hyun-seok Kim,Jin-Ho Kim,Ki-Tae Kim,Yong-Mook Kang,Hyo-Jun Ahn,Shi Xue Dou,Jai-Young Lee +8 more
TL;DR: In this article, the nanosized Mg 0.6 Ni 0.4 O was used to prevent polysulfide dissolution into liquid electrolytes and to promote the Li/S redox reaction.
Journal ArticleDOI
The trapping and transport phenomena of hydrogen in nickel
Sung-Man Lee,Jai-Young Lee +1 more
TL;DR: In this paper, it is suggested that both hydrogen trapping at grain boundaries and short-circuit diffusion through grain boundaries in nickel are present, and the trap binding energy at grain boundary is estimated as 20.5 kJ ⋅ mol-1.
Journal ArticleDOI
Hydrogen trapping by TiC particles in iron
Hwan-Chul Lee,Jai-Young Lee +1 more
TL;DR: In this article, the interaction of hydrogen with the interface of TiC inclusion in iron was studied by thermal analysis technique using gas chromatrograph as hydrogen detector and the amount of hydrogen evolved from trap site was measured and its relations with activation energy and trap binding energy were studied.
