Preparation of UV Curable Gel Polymer Electrolytes and Their Electrochemical Properties

Autor: Hee Woo Rhee, Bookeun Oh, Dong-Won Kim, Won Il Jung

Publikováno v: Bulletin of the Korean Chemical Society. 23:683-687

We have investigated the effect of the number of ethylene oxide (EO) units inside poly(ethylene glycol) dimethacrylate (PEGDMA) on the ionic conductivity of its gelled polymer electrolyte, whose content ranges from 50 to 80 wt%. PEGDMA gelled polymer

Flexible Polymer Battery with Conducting Polymer as a Cathode

Autor: Hee-Woo Rhee, Won Il Jung, Min-Kyu Song

Publikováno v: Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals. 316:337-340

Li polymer batteries were made of Li metal anode, UV cured polymer electrolyte and conducting polymer cathode, polypyrrole (PPy). PPy film doped with dodecylbenzenesulfonic acid (DBSA) showed high conductivity (∼10 S/cm) and solubility (∼90%) in
