Samsung SDI participated in Eurobike 2015 held in Friedrichshafen, Germany to showcase its various lithium-ion battery technologies for electric bicycles. Samsung SDI exhibited six types of standardized battery packs that can be either built-in or installed on the outside bike for immediate use. It also displayed 12 types of battery packs that are currently being supplied to global manufacturing companies and the cells of various specifications.
