Enhanced Cycling Stability of O3-Type Na[Ni0.5Mn0.5]O2 Cathode through Sn Addition for Sodium-Ion Batteries

Autor: Yang-Kook Sun, Geumjae Han, Hoon Hee Ryu, Tae Yeon Yu

Publikováno v: The Journal of Physical Chemistry C. 125:6593-6600

Despite their high discharge capacity, O3-type layered cathodes for sodium-ion batteries (SIBs) suffer from rapid capacity fading caused by detrimental phase transitions. A series of O3-type layere...

High-energy O3-Na1−2xCax[Ni0.5Mn0.5]O2 cathodes for long-life sodium-ion batteries

Autor: Jongsoon Kim, Hyungsub Kim, Geumjae Han, Jang Yeon Hwang, Yang-Kook Sun, Hun-Gi Jung, Tae Yeon Yu

Publikováno v: Journal of Materials Chemistry A. 8:13776-13786

To facilitate the practical realization of sodium-ion batteries, the energy density, determined by the output operating voltage and/or capacity, needs to be improved to the level of commercial Li-ion batteries. Herein, O3-type Na0.98Ca0.01[Ni0.5Mn0.5

Silicon-Graphite Anode with High-Areal Capacity for Li-Ion Battery

Autor: Geumjae Han, Yang-Kook Sun, Peng Li

Publikováno v: ECS Meeting Abstracts. :53-53

Nowadays, researchers are increasingly interested in silicon active material for lithium-ion batteries, which could meet the ever-increasing demand for high energy density owing to their satisfactory theoretical capacity (~4200 mAh g-1). Nevertheless
