Polymer-based electrode and electrolyte components can pave the way for safe and flexible Lithium ion batteries. A total plastic battery requires an electrolyte layer to be sandwiched between thin polymer layers. Polymer components offer significant advantages including enhanced safety, stability and thin film manufacturability. In this study, we investigate the fabrication, assembly and characterization of organic and polymer based Lithium ion batteries. Specifically, we used PEO (Polyethylene oxide) for electrolyte. We used polymers PVBPT and PTMA for electrodes and utilized organic fillers and binders to improve the electrical conductivity of the polymer. These polymers work as electrode by releasing or collecting electron from Li through their radical polymer chain during charge and discharge. A flexible battery was prepared using conventional electrode and polymer electrolyte. Conventional coin cells with standard electrode and electrolyte materials were also assembled and tested for comparison. Cyclic voltammetry, electrochemical impedance spectroscopy and SEM are included.
