Autor: Wo Dum Jung, Bin-Na Yun, Hun-Gi Jung, Sungjun Choi, Ji-Won Son, Jong-Ho Lee, Jong-Heun Lee, Hyoungchul Kim

Publikováno v: APL Materials, Vol 6, Iss 4, Pp 047902-047902-6 (2018)

We demonstrate that the Li-ion conductivity can be improved by adding a certain amount of Li (x = 0.25–0.5) as a charge carrier to the composition of glass-ceramic Li7+xP3S11. Structural analysis clarified that the structural changes caused by the

Facile Method for the Formation of Intimate Interfaces in Sulfide-Based All-Solid-State Batteries

Autor: Bin-Na Yun, Seongsoo Lee, Wo Dum Jung, Hyeon-Ji Shin, Jun Tae Kim, Seungho Yu, Kyung Yoon Chung, Hyoungchul Kim, Hun-Gi Jung

Publikováno v: ACS Applied Materials & Interfaces. 14:9242-9248

Sulfide-based inorganic solid electrolytes have been considered promising candidates for all-solid-state batteries owing to their high ionic conductivity. Compared with oxide-based inorganic solid electrolytes which require high-temperature sintering

Sulfide solid electrolytes (SEs) with high Li-ion conductivities (σion) and soft mechanical properties have limited applications in wet casting processes for commercial all-solid-state batteries (ASSBs) because of their inherent atmospheric and chem

Tomographical analysis of electrochemical lithiation and delithiation of LiNi0.6Co0.2Mn0.2O2 cathodes in all-solid-state batteries

Autor: Hun-Gi Jung, Byoung-In Sang, Ji-Won Son, Sungjun Choi, Hyoungchul Kim, Wo Dum Jung, Tae Hyun Kim, Bin Na Yun, Kyung Yoon Chung

Publikováno v: Scripta Materialia. 165:10-14

We demonstrated the use of three-dimensional (3D) atom-probe tomography (APT) for analyzing the electrochemical lithiation/delithiation in the composite cathodes of all-solid-state batteries (ASSBs). 3D APT provides direct determination of the Li-ion

Atomistic Assessments of Lithium-Ion Conduction Behavior in Glass–Ceramic Lithium Thiophosphates

Autor: Byung-Kook Kim, Hyoungchul Kim, Ji-Su Kim, Jong-Ho Lee, Hun-Gi Jung, Wo Dum Jung, Kyung-Yoon Chung, Ji-Won Son

Publikováno v: ACS Applied Materials & Interfaces. 11:13-18

We determined the interatomic potentials of the Li-[PS43–] building block in (Li2S)0.75(P2S5)0.25 (LPS) and predicted the Li-ion conductivity (σLi) of glass–ceramic LPS from molecular dynamics. The...

Superionic Halogen-Rich Li-Argyrodites Using In Situ Nanocrystal Nucleation and Rapid Crystal Growth

Autor: Wo Dum Jung, Kyung Yoon Chung, Jong-Ho Lee, Ji-Su Kim, Sungjun Choi, Jong Heun Lee, Byung-Kook Kim, Minjae Jeon, Hyoungchul Kim, Hun-Gi Jung, Seongmin Kim

Publikováno v: Nano letters. 20(4)

Although several crystalline materials have been developed as Li-ion conductors for use as solid electrolytes in all-solid-state batteries (ASSBs), producing materials with high Li-ion conductivities is time-consuming and cost-intensive. Herein, we i
