Hyperflow – The flexible Technology
The Cayrex team, developed a multi material Hyperflow battery which is an innovative hybrid flow battery designed for robust and flexible operation. Its primary advantage lies in its ability to function with various types of safe and non flammable zinc based electrolytes without requiring changes or adjustments to the battery itself – one battery, multiple chemistries options. This flexibility allows the use of different electrolytes, each offering unique benefits, such as low-temperature operation, high power output, high energy density, or extended cycle life. Customers can easily select the electrolyte best suited to their specific application.
Additionally, this broad range of electrolyte options is economically significant, as raw material prices are constantly fluctuating. The battery’s adaptability to cost-effective electrolytes ensures competitiveness in a dynamic market. The Hyperflow battery is engineered to operate in both static and hybrid flow modes, offering versatility for diverse applications.
Dual Operating Modes – Static and Flow Hybrid Mode
Static Mode
In static mode, the battery operates without a pump or an external electrolyte reservoir. The pump and reservoir remain inactive, and the battery functions solely as a cell stack. This configuration allows the battery to work in two ways: either as a system where the pump and electrolyte tank are connected but inactive, or as a completely independent battery stack without any connection to an external electrolyte supply. The latter setup reduces overall system size, making it more compact and space-efficient. Additionally, this mode enables faster recharging, though the capacity depends entirely on the amount of electrolyte stored within the cells.
Static mode is particularly advantageous for charging from solar panels during low sunlight conditions or other scenarios with limited charging energy. In such cases, the solar panels charge only the battery cells without involving the reservoir. If additional capacity is required, more electrolyte can be added to the system.
Flow / Hybrid Flow Mode
In flow mode, the electrolyte is stored in an external reservoir and pumped into the cells as needed. The battery’s capacity in this configuration is determined by the total volume of electrolyte available in both the cells and the reservoir. Unlike competing flow batteries (e.g., VRFB, all-iron flow, or Zn-Br systems), the Hyperflow battery does not require continuous pumping of the electrolyte. Instead, the pump activates only when a voltage drop occurs.
This intermittent pumping significantly enhances energy efficiency, as the pumps operate only when necessary, running for just a few minutes to create an electrolyte flow loop.
Optimized Performance and Upgradability
The performance and efficiency of the Hyperflow battery are largely dependent on electrolyte properties, including cycle life, energy density, and operating temperature range. Continuous electrolyte improvement is crucial and the system is designed for easy upgrades. Users can enhance performance by replacing the old electrolyte with an improved version without making any modifications to the battery.
When the battery’s capacity diminishes to 80–70% or it just needs some upgrade, it can be refreshed – upgraded simply by replacing the electrolyte. This process is cost-effective, requiring only new electrolyte rather than a complete battery replacement, as with lithium or lead-acid systems. The used electrolyte can be recycled and optimized for new production, minimizing environmental impact.
Hyperflow is not just a battery; it’s a sustainable and adaptable energy solution for the future.
