Optimization of hydrothermal synthesis of nickel oxide with flower-like structure
Autor: Thuy Thi Bich Tran, Eui-Jeong Park, jong tae son
Herein, nano-flower NiO is successfully fabricated via a simple hydrothermal process using urea and nickel(II) nitrate as reactants, followed by a calcination reaction. Final products with different morphologies are obtained by varying the molar rati

Dramatic enhancement of the electrochemical property of nano-fiber Li[Ni0.9Co0.05Al0.05]O2 as a lithium-ion battery cathode material using a polypyrrole coating
Autor: Seong-Jae Kim, Eui Jeong Park, Hae In Kim, Jong-Tae Son, Hyun Ju Jang
Publikováno v: Journal of the Korean Physical Society. 79:567-572
The Li[Ni0.9Co0.05 Al0.05]O2 (NCA) cathode material was continuously coated with polypyrrole (ppy), which is a conductive polymer, to improve its life-cycle characteristics. The thickness of the coating layer was about 4.2 nm. The electrochemical per
