The V-KOR stack development program is at an advanced stage and has been delivered through a consortium which includes Japanese and German technical partners.
The V-KOR development team has utilised advanced automated manufacturing techniques and a new high performance flexible bipolar plate to deliver a stack that incorporates the unique V-KOR stack IP.

This leading-edge approach to serial manufacturing of the stack is essential to the future commercial success of the V-KOR technology. The V-KOR stack development effort is a key part of the program targeting delivery of the most cost-effective grid scale vanadium battery available in Australia and the world.
The targeted improvement in product cost and efficiency are a core part of the V-KOR commercialisation pathway towards the provision of grid scale installations.
