Electrochemical Supercapacitor for Energy Storage

Many countries worldwide are investing in renewable energy sources to protect natural resources for a sustainable future. Electricity consumption uses more than one-third of the country's total daily oil production in the Kingdom of Saudi Arabia (KSA). As a result, the KSA government is concerned about the country's future economy and is investing in sustainability initiatives. There is an urgent need to create efficient, sustainable, and clean energy technologies with no or low greenhouse gas emissions and energy storage technologies to assure a continuous clean energy supply. Many of such technologies are now well-established, but there is a serious need to develop new materials with superior properties that can improve the efficiency of clean energy production and storage technologies with a long life cycle. Supercapacitors are outstanding energy storage devices and can store and deliver energy at relatively high rates. Supercapacitors offer high-power density, good operational safety, and good cycling life, so they have been an excellent energy storage platform with significant potential. The KSA is enriched with solar and various kinds of biomasses resources; utilizing these resources for energy technology will produce low-cost and sustainable supercapacitors. Herein, novel electrode materials and electrolytes will be prepared from various local resources like biomass, industrial waste, as well as some commercial resources. Various types of electrode materials and electrolytes will be used to fabricate different types of supercapacitors for multiple applications. For example, long cycle-life perovskitebased photo-electrochemical supercapacitors will be developed for integrated energy harvesting and storage applications. KSA biomass/industrial waste-based carbonaceous materials, nanostructured metal oxides, conducting polymers, petrochemical wastes, biomass-derived carbon, graphene and other nanostructured materials will be used to develop flexible, long life-cycle and high performed supercapacitors for wearable/electronic industries. The density functional theory framework will be used for predicting novel electrode materials for supercapacitors. A power management unit will be designed for a battery-less wearable heart monitor. The development of such sustainable and high-performance supercapacitors will potentially fill the gap between energy demands and production and contribute to the KSA's vision for a sustainable economy
