Energy Storage Technologies

Technology Overview

Energy storage technologies are vital for smart grids, electric vehicles and consumer electronics. Our team has expertise in the area of energy storage materials such as materials for Li-ion and Na-ion batteries. For large scale energy storage, our team has developed a technology on Redox Flow Li-ion Battery which is suitable for large scale, high performance grid storage. We have also developed Sodium-ion battery technology (see below for a brief description of the technical features). Besides the above examples, our expertises lies in the following areas:

  • Materials for energy storage – Anodes and Cathodes for Li-ion and Na-ion batteries
  • Anodes – Titanium dioxide, Lithium titanates, Iron oxide, Sodium based anodes
  • Cathodes – Lithium iron phosphates (modified), Lithium vanadium phosphates, Lithium metal oxides, Sodium metal phosphates
  • Electrolytes for energy storage systems

Technology Features & Specifications

Sodium-ion Battery

Sodium-ion battery technologies are ideal candidates to be deployed in large-scale energy storage applications due to their electrochemical properties, stability and low-cost. By employing a soft template synthesis approach, the intercalation/de-intercalation of the sodium ions and other properties in this material has been enhanced. For example, mesoporous Na3V2(PO4)3/C synthesized using this method demonstrates enhanced sodium storage capability over a very long cycle life (30,000 cycles), even at very high current rates (40 deg C).

Potential Applications

  • Li-ion battery / Na-ion battery
  • Smart Grid
  • Redox flow Li-ion battery
  • Battery for Electric Vehicle

Market Trends and Opportunities

The rapidly growing market for traction batteries for electric vehicles has been forecasted to exceed $55Bn (2012-2022). In vehicles, the largest use of battery is in the forklifts and e-bike sectors followed by mobility aids for the disabled or aged. However, there is an increasing demand from the hybrid cars sector.
