Journal ArticleDOI
Mussel‐Inspired Adhesive Binders for High‐Performance Silicon Nanoparticle Anodes in Lithium‐Ion Batteries
Myung-Hyun Ryou,Jangbae Kim,Inhwa Lee,Sunjin Kim,You Kyeong Jeong,Seonki Hong,Ji Hyun Ryu,Taek-Soo Kim,Jung-Ki Park,Haeshin Lee,Jang Wook Choi +10 more
TL;DR: The unique wetness-resistant adhesion provided by the catechol groups allows the silicon nanoparticle electrodes to maintain their structure throughout the repeated volume expansion and shrinkage during lithiation cycling, thus facilitating substantially improved specific capacities and cycle lives of lithium-ion batteries.
Journal ArticleDOI
Light-Weight Free-Standing Carbon Nanotube-Silicon Films for Anodes of Lithium Ion Batteries
TL;DR: A novel anode structure free of heavy metal current collectors is reported by integrating a flexible, conductive carbon nanotube (CNT) network into a Si anode, which offers approximately 10 times improvement in specific capacity compared with widely used graphite/copper anode sheets.
Journal ArticleDOI
Bendable inorganic thin-film battery for fully flexible electronic systems.
Koo Min,Kwi-Il Park,Seung Hyun Lee,Minwon Suh,Duk Young Jeon,Jang Wook Choi,Kisuk Kang,Keon Jae Lee +7 more
TL;DR: This paper presents a flexible thin-film LIB developed using the universal transfer approach, which enables the realization of diverse flexible LIBs regardless of electrode chemistry and can form high-temperature (HT) annealed electrodes on polymer substrates for high-performance LIBs.
Journal ArticleDOI
Silicon carbide-free graphene growth on silicon for lithium-ion battery with high volumetric energy density
In-Hyuk Son,Jong Hwan Park,Soonchul Kwon,Seongyong Park,Mark H. Rümmeli,Alicja Bachmatiuk,Hyun Jae Song,Jun-Hwan Ku,Jang Wook Choi,Jae-Man Choi,Seok-Gwang Doo,Hyuk Chang +11 more
TL;DR: Direct graphene growth over silicon nanoparticles without silicon carbide formation is reported, suggesting that two-dimensional layered structure of graphene and its siliconcarbide-free integration with silicon can serve as a prototype in advancing silicon anodes to commercially viable technology.
Journal ArticleDOI
Nitrogen-Doped Multiwall Carbon Nanotubes for Lithium Storage with Extremely High Capacity
TL;DR: Nitrogen doping enables unprecedented cell performance by engaging anomalous electrochemical phenomena such as nanoparticles division into even smaller ones, their agglomeration-free diffusion between nitrogen-doped sites as well as capacity rise with cycles.
