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
A safe and sustainable bacterial cellulose nanofiber separator for lithium rechargeable batteries
Hyeokjo Gwon,Kitae Park,Soonchun Chung,Ryoung-Hee Kim,Jinkyu Kang,Sang Min Ji,Nag-Jong Kim,Sunghaeng Lee,Jun-Hwan Ku,Eun Cheol Do,Sujin Park,Minsang Kim,Woo Yong Shim,Hong Soon Rhee,Jae-Young Kim,Jieun Kim,Tae Yong Kim,Yamaguchi Yoshitaka,Iwamuro Ryo,Shunsuke Saito,Gahee Kim,In-Sun Jung,Hyokeun Park,Chanhee Lee,Seungyeon Lee,Woo Sung Jeon,Woo Dae Jang,Hyun Uk Kim,Sang Yup Lee,Dongmin Im,Seok-Gwang Doo,Sang Yoon Lee,Hyun Chul Lee,Jin Hwan Park +33 more
TL;DR: A strain with the highest BCNF yield ever reported is systematically constructed by increasing metabolic flux and improved safety by introducing a Lewis base to overcome thermochemical degradation in the battery.
Journal ArticleDOI
Aluminum manganese oxides with mixed crystal structure: high-energy-density cathodes for rechargeable sodium batteries.
TL;DR: The findings regarding the phase transformation and structure stabilization induced by incorporation of aluminum, closely related to the structural analogy between orthorhombic Na( 0.44) MnO2 and NaAl(0.9) O2, suggest a strategy for achieving sodium rechargeable batteries with high energy density and stability.
Journal ArticleDOI
Poly(isobutylene-alt-maleic anhydride) binders containing lithium for high-performance Li-ion batteries
Jun-Hwan Ku,Seung-Sik Hwang,Dongjin Ham,Min-Sang Song,Jeong-kuk Shon,Sangmin Ji,Jae-Man Choi,Seok-Gwang Doo +7 more
TL;DR: In this article, an artificial pre-SEI on graphite electrode using a polymer binder containing lithium (i.e., a Li-copolymer of isobutylene and maleic anhydride, Li-PIMA) and its effect on the anode performances was investigated.
Patent
Polymer composition for lithium secondary battery, electrode for lithium secondary battery including the same, and lithium secondary battery including the electrode
TL;DR: A polymer including the first repeating unit represented by Formula 1, a polymer composition for a lithium battery including the polymer, an electrode for a battery including polymer composition and the electrode as mentioned in this paper.
