A crystalline organic electrolyte for safe, room-temperature operable all-solid-state sodium batteries

Autor: Hochun Lee, Bonhyeop Koo, Seokbum Kang, Chang-eui Yang, Seung-Tae Hong, Boosik Jeon

Publikováno v: Energy Storage Materials. 39:259-264

Owing to their mitigated safety risk and high energy density, all-solid-state sodium batteries are promising post-Li batteries. However, current solid-state electrolytes have insufficient ionic conductivity, electrochemical stability, and contacting

Spectroscopic Studies of Solution Structure and Ion Conduction in Concentrated Aqueous Electrolytes

Autor: Bonhyeop Koo, Hochun Lee

Publikováno v: ECS Meeting Abstracts. :409-409

Aqueous Li-ion batteries have been spotlighted because they are potentially low in cost, safe, and environmentally friendly. However, they suffer from low energy density due to limited cell voltage. Concentrated aqueous electrolytes have been attract

Wide temperature cycling of Li-metal batteries with hydrofluoroether dilution of high-concentration electrolyte

Autor: Kisung Park, Hochun Lee, Bonhyeop Koo, Youngseong Jo, Hongkyung Lee

Publikováno v: Chemical Engineering Journal. 427:131889

The safe, stable cycling of Li-metal batteries (LMBs) over wide temperature ranges is crucial for practical applications, even in extreme environments. Although LMB performance has been enhanced using various high-concentration electrolytes (HCEs) wi

Physicochemical nature of polarization components limiting the fast operation of Li-ion batteries

Autor: Junsik Kang, Hochun Lee, Seokbum Kang, Bonhyeop Koo

Publikováno v: Chemical Physics Reviews. 2:041307

High-power Li-ion batteries (LIBs) are widely used in electric vehicles and grid storage applications and are therefore in high demand; however, their realization requires a fundamental understanding of electrochemical polarization arising during cha
