Early Academic Pursuits
Saloua Merazga began her academic journey in the field of physics at CONSTANTINE University, where she obtained her Licence degree in Physics in 2007. Her growing interest in the specialized area of thin films led her to pursue a Master’s degree, which she completed in 2009 with a thesis titled "Crystallization of thin films of amorphous silicon carbide". This period marked the beginning of her deep engagement with materials science, particularly focusing on silicon carbide, which would remain a central theme throughout her career.
Professional Endeavors
Merazga's professional career has been characterized by a blend of teaching and research. From 2010 to 2012, she served as a part-time professor at both Constantine University and USTHB University in Algeria. These roles allowed her to share her knowledge and inspire the next generation of physicists. Following this, she spent a year teaching at a high school in Algeria, further expanding her teaching portfolio.
Her transition to full-time research came in June 2016 when she joined the Research Center of Semiconductor Technology for Energetic (CRTSE) in Algeria as a physicist researcher. During her tenure at CRTSE, her research concentrated on the nanostructuring of silicon via electrochemical anodization, the deposition of palladium nanoparticles using electroless methods, and the synthesis of magnesium-based alloys for electrochemical hydrogen storage applications.

From October 2020 to the present, Merazga has continued her research at CRTSE, shifting her focus towards the synthesis of TiO2/Li4Ti5O12 (LTO) nanoparticles and LTO/Si composites. These materials are critical for the development of high-performance anodes in lithium-ion batteries. Her work includes detailed electrochemical measurements of these powders, contributing to advancements in battery technology, which is crucial for the growing demand for efficient and sustainable energy storage solutions.
The development and deployment of energy storage technologies are crucial for advancing the transition to a sustainable energy future. Battery storage, particularly lithium-ion batteries, has seen significant advancements and cost reductions, making it the most widely used ESS for both grid-scale and residential applications. Innovations in other storage methods, such as flow batteries and solid-state batteries, are also being explored to improve performance and safety. Additionally, energy storage supports grid modernization efforts by providing ancillary services such as frequency regulation, voltage support, and black start capabilities. As the global push towards decarbonization intensifies, energy storage will play an increasingly vital role in ensuring a resilient, efficient, and clean energy system.

Energy storage refers to the capture of energy produced at one time for use at a later time, enabling a balance between energy supply and demand. This technology is pivotal in the integration of renewable energy sources, such as solar and wind, which are intermittent by nature. Energy storage systems (ESS) can store excess energy generated during periods of low demand and release it when demand peaks, thereby enhancing the reliability and stability of the power grid. Various forms of energy storage include batteries, pumped hydroelectric storage, compressed air energy storage, and thermal storage. These technologies differ in terms of capacity, efficiency, and application, but all contribute to reducing greenhouse gas emissions by maximizing the use of clean energy.
