Technical FAQs 4

What is the difference between flow and lithium ion batteries?

Both flow and lithium ion batteries provide renewable energy storage solutions. Both types of battery technology offer more efficient demand management with lower peak electrical demand and lower utility charges. Key differences between flow batteries and lithium ion ones include cost, longevity, power density, safety and space efficiency.

Are flow batteries safer than lithium ion batteries?

Flow batteries are generally considered safer than lithium-ion batteries. The risk of thermal runaway is low, and they are less prone to catching fire or exploding. Lithium-ion Batteries Lithium-ion batteries ‘ safety is a significant concern due to their susceptibility to thermal runaway, which can lead to fires or explosions.

What are lithium ion batteries?

Lithium ion batteries is a leading rechargeable battery storage technology with a relatively short lifespan (when compared to flow batteries). Their design involves only one encased battery cell in which electrolytes mix with conductors to charge and discharge.

How do flow batteries work?

Flow batteries operate by circulating liquid electrolytes through a cell stack, where electrochemical reactions occur to store or release energy. Store the electrolytes in external tanks and adjust their flow rate to scale the power output.
