Gas Evolution Kinetics in Overlithiated Positive Electrodes and its Impact on Electrode Design
Autor: Munsoo Song, Danwon Lee, Juwon Kim, Subin Choi, Ikcheon Na, Sungjae Seo, Sugeun Jo, Chiho Jo, Jongwoo Lim
Publikováno v: Advanced Science, Vol 11, Iss 22, Pp n/a-n/a (2024)
Abstract Increasing lithium contents within the lattice of positive electrode materials is projected in pursuit of high‐energy‐density batteries. However, it intensifies the release of lattice oxygen and subsequent gas evolution during operations

One-Pot Heterointerfacial Metamorphosis for Synthesis and Control of Widely Varying Heterostructured Nanoparticles
Autor: Jianan Liu, Yoonjae Jung, Gyeong-Hwan Kim, Youngju Son, Jian Wang, Jeong-Wook Oh, Limin Pan, Sungjae Seo, Taeghwan Hyeon, Jungwon Park, Jwa-Min Nam, Mouhong Lin, Jongwoo Lim, Yeon-Hee Lee
Publikováno v: Journal of the American Chemical Society. 143(9)
Despite remarkable facileness and potential in forming a wide variety of heterostructured nanoparticles with extraordinary compositional and structural complexity, one-pot synthesis of multicomponent heterostructures is largely limited by the lack of

Revealing Solvent Effects on Ion Insertion within Battery Primary Particles Using Operando Scanning Transmission X-Ray Microscopy
Autor: Sugeun Jo, Nam Dong Kim, Jinkyu Chung, Jeong Woo Han, Jongwoo Lim, Sungjae Seo, Juwon Kim, Young-Sang Yu, Danwon Lee, David A. Shapiro, Hyun-Joon Shin, Bonho Koo
Publikováno v: ECS Meeting Abstracts. :3189-3189
LiFePO4 (LFP), the attractive commercial cathode materials, exhibits the phase separation between lithium-poor and lithium-rich phase within individual particles due to the wide miscibility gap. The boundaries between such phases develop large stress
