Sustainable Energy Storage for a Circular and Resilient Future

The Center of Excellence for Research in Engineering Materials (CEREM) at King Saud University is advancing sodium-ion battery (SIB) technologies to support sustainable energy storage and diversify battery material supply chains. Because sodium resources are abundant and associated costs are lower, sodium-ion battery technologies offer a promising solution for stationary energy storage, renewable energy integration, and grid resilience. CEREM’s research contributes to the development of a circular economy and advances national energy diversification objectives.

• Resource Abundance

         Sodium is widely available, reducing dependence on scarce resources and supporting long-term energy security.

• Cost Stability

          Abundant raw materials can lower production costs and reduce vulnerability to fluctuations in lithium prices.

• Grid-Scale Suitability

          Sodium-ion batteries demonstrate significant potential for renewable energy storage, peak shaving, and stationary energy applications.

• Sustainability Alignment

         Sodium-ion technology supports resource recovery, advances circular economy objectives, and contributes to national energy diversification strategies.

Future Directions at CEREM

Research Infrastructure & Experimental Capabilities

CEREM maintains advanced laboratory infrastructure to support the development and evaluation of sodium-based energy storage materials. Our facilities enable controlled synthesis, safe handling of air- and moisture-sensitive components, and comprehensive characterization of electrochemical performance.

These abilities help us carefully study how cathodes and electrolytes work together, how sodium ions move, how stable the interfaces are, and how well the materials perform.

Core Facilities Supporting Sodium-Ion Research

Inert Atmosphere Glove Box System

The system provides a controlled argon environment for preparing sodium-based materials and assembling electrochemical cells.

Electrochemical Analysis Systems (Ivium Potentiostat/Galvanostat)

The precise potentiostat/galvanostat system is used to perform CV, EIS, and charge-discharge tests on sodium-ion

These facilities support both fundamental materials research and applied performance optimization studies relevant to scalable energy storage systems.

CEREM continues to strengthen its work in:

• Advanced cathode and anode material engineering
• Electrolyte optimization and interface stabilization
• Sustainable sodium resource utilization
• Scalable materials processing for infrastructure-level applications
