ZBM2 zinc-bromine flow battery

Rewriting battery rules. 100% storage. 100% available

Redflow’s ZBM2 battery is a unique energy storage system that redefines your understanding of how a battery works. This scalable 10 kilowatt-hour (kWh) zinc-bromine flow battery can deliver 100 per cent depth of discharge each day – without causing any damage to the battery.

High performance. At high temperatures

The ZBM2 performs flawlessly in warm climatic conditions without external cooling. Unlike legacy battery chemistries, the performance, safety and operational lifetime of the ZBM2 zinc-bromine flow battery is unaffected by ambient temperatures as warm as 50°C (122°F).

10-year Warranty

Redflow backs ZBM2 with a 10-year warranty (see full warranty for details).

Scalable storage. From one to dozens

The ZBM2 zinc-bromine flow battery is designed to work on its own and can also scale to work as part of a much larger energy storage system, with as many batteries as you require.  ZBM2s are easy to deploy in scalable parallel clusters for high availability, high scale deployments at the largest sites.

Internet-ready. For easy remote access

The ZBM2 battery management system (BMS) captures performance data in real-time to enable 24/7 remote monitoring. Monitor and manage your ZBM2 batteries from your computer or mobile phone, using easy web-based notifications and controls.

Environment-friendly battery. Fully recyclable

The ZBM2 zinc-bromine flow battery is made from easily recycled or reused components. At its end of life, the battery’s zinc bromide electrolyte solution can be purified and used for new batteries.

Safe energy storage. Wherever you need it

ZBM2s are intrinsically safe devices, even when used in the most demanding locations. The temperature-tolerant zinc-bromine flow battery contains an inherently non-flammable electrolyte solution, with a design that means there’s no chance of ‘thermal runaway’.

Simple. One-step charging

Using 100 per cent of its 10 kWh energy storage capacity, Redflow’s ZBM2 zinc-bromine flow battery delivers a constant power supply, due to a flat voltage curve and simple one-stage charge profile.

Standby for years. Start in seconds

The ZBM2 zinc-bromine flow battery can be stored at any state of charge – from full to empty – for weeks, months or even years. When you need power, the ZBM2’s Standby Power System (SPS) can start the battery in seconds, ready to deliver its stored energy. Please contact Redflow for further details on this option.

Redflow. Redefines the battery

Redflow’s zinc-bromine flow battery redefines your understanding of how a battery works. With 100 per cent depth of discharge daily, the ZBM2 delivers a sustained 10kWh of energy storage capacity throughout its operating life.
