Title: Bridging Batteries and Supercapacitors: How Electrode Structure Shapes Hybrid Energy Storage Devices

Abstract:

Electrochemical energy storage (EES) technologies, encompassing batteries, supercapacitors, and supercapatteries are essential for achieving sustainable and efficient energy systems. The performance of these devices is strongly governed by the structure and properties of their electrodes, which determine charge storage mechanisms, ion transport, and stability. This presentation examines how nanostructuring, porosity control, surface modification, and defect engineering influence electrochemical behavior and overall device efficiency. Examples such as carbon compositing, metal doping, and binder-free electrode fabrication demonstrate how tailored structural designs enhance conductivity, reversibility, and long-term cycling stability. By bridging the functional characteristics of batteries and supercapacitors, hybrid energy storage systems can simultaneously deliver high energy and power densities. Advancements in electrode structure engineering are thus central to realizing the next generation of lightweight, durable, and sustainable energy storage technologies.

Biography:

Dr. Fatin Saiha Omar is a Senior Lecturer at the Faculty of Science and Technology, Universiti Kebangsaan Malaysia (UKM), specializing in experimental physics and electrochemical energy storage. She earned her Ph.D. from the University of Malaya in 2018, where her research focused on developing metal oxides and metal phosphates composited with conducting polymers and graphene for energy storage and electrochemical sensor applications. Following her doctorate, Dr. Fatin served as a Postdoctoral Research Fellow (2019), expanding her expertise into electrode materials and polymer electrolytes for dye-sensitized solar cells. Since joining UKM in 2020, her research has centered on the engineering of nanomaterials with tailored dimensionalities (1D/2D/3D) for advanced electrochemical energy storage systems.
