Enhanced capacity retention based silicon nanosheets electrode by CMC coating for lithium-ion batteries
Autor: Heon Jin Choi, Byung Won Cho, Sangwon Park, Jeong Min Park, Jung Hoon Ha
Publikováno v: Electronic Materials Letters. 17:268-276
Si nanosheets (SiNS) as two dimensional Si nanomaterials are promising candidates for anodes of lithium ion batteries (LIBs) by their large surface area and excellent mechanical durability. In this study, we fabricated polymeric binder (carboxymethyl

Facile topotactic synthesis of tavorite LiFeSO 4 F using supercritical methanol
Autor: Kwan Young Lee, Su Jin Kim, Boeun Lee, Byung Won Cho, Si Hyoung Oh
Publikováno v: Journal of Power Sources. 398:27-33
For the first time, tavorite-structured LiFeSO4F is synthesized using supercritical methanol at 300 °C within a short reaction time of 15 min. The synthesis involves topotactic insertion of LiF in the supercritical solution into szomolnokite-type Fe

Improved performance of dual-conducting polymer-coated sulfur composite with high sulfur utilization for lithium-sulfur batteries
Autor: Byung Won Cho, Yoon-Sung Lee, Tae-Gyung Jeong, Hun-Gi Jung, Kyung Yoon Chung, Yong-Tae Kim
Publikováno v: Journal of Alloys and Compounds. 742:868-876
This study is aimed at alleviating the inherent disadvantages of sulfur cathodes in lithium-sulfur (Li-S) batteries by encapsulating the sulfur particles with a dual (ionic and electronic)-conducting polymer via a simple, single-step procedure. Succe
