Abstract High-voltage operation of Ni-rich layered cathodes in lithium-ion batteries (LIBs) induces oxygen redox reactions, leading to singlet oxygen evolution, interfacial degradation, and electrolyte decomposition. While cathode engineeri... Read More
Abstract This study explored the multifaceted role of flavin adenine dinucleotide (FAD) in modulating proton-coupled electron transfer (PCET) processes for electrocatalysis. FAD demonstrated catalyst-dependent functionality, enhancing hydro... Read More
Abstract High-capacity Li-rich layered oxides using oxygen redox as well as transition metal redox suffer from its structural instability due to lattice oxygen escaped from its structure during oxygen redox and the following electrolyte dec... Read More
Abstract Herein, we present a gel polymer electrolyte (GPE) improving nonflammability of lithium-ion batteries (LIBs) by blocking radical-initiated chain reactions which cause thermal runaway and finally fire issues. The polymer that makes... Read More
Abstract The electrochemical co-reduction of carbon dioxide (CO2) and nitrate (NO3−) to urea via C–N bond coupling is a promising alternative to traditional industrial processes that are intensive in energy consumption and CO2 emission. How... Read More
Professor Hyun-Kon Song in the School of Energy and Chemical Engineering has been selected for the first-half of this year’s Samsung Research Funding Program for Future Technologies. Supported through Samsung’s future technology... Read More
A new rechargeable battery that can be charged wirelessly using light from indoor sources, like desk lamps has been developed. This will enable the so-called ‘Energy Recycling,’ which refers to the energy recovery process of uti... Read More
Reactive oxygen species (ROS), which is known to be a main contributor to the aging process, also adversely affects battery performance and life. Indeed, when the ROS is released from the high-capacity electrode materials for lithium-ion ba... Read More
