Evaluation of Charging Characteristics of New Li-ion Battery with WO3 Electrode Using Regenerative Power from a PMSM

Autor: Shigeyuki Takagi, Kouta Kitamura, Hideaki Hirabayashi, Yoshinori Kataoka, Akito Sasaki, Soramichi Takahashi

Publikováno v: 2020 IEEE 9th International Power Electronics and Motion Control Conference (IPEMC2020-ECCE Asia).

We developed a new Li-ion battery with a low-resistance WO 3 negative electrode and confirmed its charging performance to be more than 2.4 times that of the electric double layer capacitor (EDLC) using regenerative power from a permanent magnet synch

Effect of oxygen vacancy in tungsten oxide on the photocatalytic activity for decomposition of organic materials in the gas phase

Autor: Akito Sasaki, Hideaki Hirabayashi, Masaaki Kitano, Daisuke Fukushi

Publikováno v: Microelectronics Reliability. 79:1-4

The relationship between the oxygen vacancy of tungsten oxide and its ability to decompose organic materials under visible-light irradiation was investigated experimentally. In the field of rechargeable batteries, the highest charge-discharge rate is
