Advantages and Benefits:

  1. The method is economical approach to making the key battery material required for a new type of storage battery – solid oxide redox flow battery (SORFB) that has a potential to meet large-scale energy storage.

  2. The method is very practical and improve on system efficiency

  3. Small energy input required in order to jump-start the electrical cycle

Invention Description:

Energy storage plays a crucial role in renewable energy implementation and future smart grid. Apart from conventional pumped hydro and compressed air technologies, the availability of advanced high-performance and low-cost energy storage technology has been largely lacking.

In a previous invention, the inventors of the current invention had disclosed a new type of storage battery [solid oxide redox flow battery] that has a great potential to meet large-scale energy storage. However, this current is a complementary invention. It is an economical approach to making the key battery material of the earlier invention– redox couple material – by adding reducing carbon powder with functional Fe2O3/ZrO2 mixture. The carbon-reduced Fe/ZrO2 redox material is then used as the stating material for the battery, eliminating energy intensive H2-reduction or electrochemical reduction process.

In summary it is a new chemical approach to reducing Fe2O3 to Fe in an economical manner prior to battery assembly so that large energy input can be avoided and the system efficiency can be raised.
