A highly safe battery with a non-flammable triethyl-phosphate-based electrolyte
Autor: Kazuaki Matsumoto, Koji Utsugi, Kazuhiko Inoue
Publikováno v: Journal of Power Sources. 273:954-958
Applied in a battery with a silicon-oxide (SiO) anode, a non-flammable triethyl-phosphate (TEP)-based electrolyte with fluoroethylene carbonate (FEC) improved the safety and energy density of the battery. This TEP:FEC-based battery demonstrated almos

Suppression of aluminum corrosion by using high concentration LiTFSI electrolyte
Autor: Koji Utsugi, Kazuhiko Inoue, Ryota Yuge, Kazuaki Matsumoto, Takehiro Noguchi, Kentaro Nakahara
Publikováno v: Journal of Power Sources. 231:234-238
Although lithium bis(trifluoromethanesulfonyl imide) (LiTFSI) has a high thermal stability and fine tolerance to water and is an outstanding candidate as an electrolyte, there is an urgent need to control aluminum corrosion. Here, we explain how we s

Disordered carbon negative electrode for electrochemical capacitors and high-rate batteries
Autor: Katsuhiko Naoi, Koji Utsugi, Yoshiyuki Igarashi, Ayumu Kamakura, Nobuhiro Ogihara, Yuki Kusachi
Publikováno v: Electrochimica Acta. 52:1713-1720
In order to understand the properties of high-rate capability and cycleability for a disordered carbon negative electrode in LiPF6/PC based electrolyte solution, the cell performance tests with various rates and depth of discharges (DODs) has been st

Effect of Using Fluorinated Ether and Sulfone As Electrolyte Solvents for Lithium Ion Batteries with Lithium Rich Layered Cathode and Silicon Oxide Anode
Autor: Takehiro Noguchi, Takuya Hasegawa, Hideki Yamauchi, Ikiko Yamazaki, Koji Utsugi
Publikováno v: ECS Meeting Abstracts. :342-342
Introduction Li rich layered cathode is one of the candidates for next generation cathode active material of Lithium ion batteries, because of large capacity more than 250 mAh/g. On the other hand, because of the higher potential than conventional ca

P‐30: Fine Patterning of Lateral Three Color Emitters for Organic EL Devices Using a Metal Mask Sliding in Vacuum Vapor Deposition
Autor: Koji Utsugi, Etsuo Hasegawa, Masashi Tamegai
Publikováno v: SID Symposium Digest of Technical Papers. 31:640-643
In order to form high-resolusion pixels for a small organic elctroluminescent (EL) device having a three-color independent emission system using a low molecular evaporation method, a metal mask sliding control system with a pulse control motor was ma

Organic electroluminescent devices with molecularly doped polymers and anode interface phthalocyanine layer
Autor: Koji Utsugi, Hiroshi Tada
Publikováno v: Polymers for Advanced Technologies. 8:443-448
We studied the properties of organic electroluminescent devices using molecularly doped polymers as a hole transport layer and having a metal-free phthalocyanine (H2Pc) layer between anode and hole transport layer. A vacuum-deposited H2Pc metastable
