Mrs. Puteh Melor Wesma bt. Salehen, our PhD Student in Solar Energy Research Institute (SERI), Universiti Kebangsaan Malaysia has completed her short-attachment training at Ångström Advanced Battery Centre, Department of Chemistry,Uppsala University, Sweden on 1st October to 30 November 2018. During the training period, she worked on composite anode materials using polysaccharides derivate as binder in lithium ion battery. The project aims to study the potential of carboxymethyl chitosan and carboxymethyl carrageenan as a new binder in lithium ion battery (LIB) and to evaluate the performance of new composite electrode material in LIB.
