Study on the deterioration mechanism of layered rock-salt electrodes using epitaxial thin films; Li(Ni, Co, Mn)O$$_{2}$$ and their Zr-O surface modified electrodes

Abe, Machiko*; Iba, Hideki*; Suzuki, Kota*; Minamishima, Hiroaki*; Hirayama, Masaaki*; Tamura, Kazuhisa; Mizuki, Junichiro*; Saito, Tomohiro*; Ikuhara, Yuichi*; Kanno, Ryoji*

Journal of Power Sources, 345, p.108 - 119, 2017/03

The surface structure of the Li(Ni, Co, Mn)O$$_{2}$$ electrode was studied during charge/discharge process using electrochemical methods and X-ray/Neutron scattering techniques. It was found that during charge/discharge process the coverage of spinel structure increased. The spinel structure has low electrochemical activity and is not involved in Li insertion/extraction. After the surface modification, it was found that the coverage of the spinel structure did not increase. Further, it was also found out that the Li concentration at the electrode/electrolyte interface increased.

Decomposition of phenolic endocrine disrupting chemicals by potassium permanganate and $$gamma$$-ray irradiation

Abe, Yasuhiro*; Takigami, Machiko; Sugino, Koji*; Taguchi, Mitsumasa; Kojima, Takuji; Umemura, Tomonari*; Tsunoda, Kinichi*

Bulletin of the Chemical Society of Japan, 76(8), p.1681 - 1685, 2003/08

The decomposition of phenolic endocrine disrupting chemicals (P-EDCs), such as phenol, 4-butylphenol (BuP), and bisphenol A (BPA), in aqueous solutions by potassium permanganate (KMnO$$_{4}$$) was studied and its efficiency was compared with that of hydroxyl radicals (OH$$^{.}$$) generated by $$^{60}$$Co $$gamma$$-ray irradiation. Various organic acids and inorganic carbon were formed in the decomposition of P-EDCs due to either KMnO$$_{4}$$ or OH$$^{.}$$. They were formed via direct aromatic ring cleavage in the case of KMnO$$_{4}$$ and OH$$^{.}$$ addition-substitution reactions followed by aromatic ring cleavage in the case of OH$$^{.}$$. Comparing the decrease in the P-EDCs based on the number of electrons, the amount of KMnO$$_{4}$$ spent to completely eliminate BuP and BPA was comparable to the amount of OH$$^{.}$$. Although three times more KMnO$$_{4}$$ was needed for phenol than OH$$^{.}$$, the complete conversion of phenol into organic acids and inorganic carbon was achieved with 720$$mu$$M of electrons in both cases.
