This published paper on the development of the ZBM Gen 3 shows many improvements for operating lifespan and manufacturing cost reduction.

A follow-on Assessment of the Progress in Refining the Gen2 ZBM Product
for RedFlow Technologies Ltd. Brisbane, Queensland, Australia

by Garth P. Corey
Energy Storage Systems Engineer

Purpose
The purpose of this document is to present my findings from the follow-on assessment that I have completed in my study of the scope and success of the improvements made to the initial RedFlow ZBM Gen2 design which has resulted in the development of the ZBM Gen3 product.

Introduction
In early September, 2010, I visited the RedFlow offices in Brisbane, Queensland, Australia, to perform an on-site assessment of the state of the development effort for an advanced Zinc Bromine technology flow battery. Over a 4-day period, I was provided with detailed information on the early development effort of the ZBM Gen2 device. I evaluated initial progress toward commercialism and future plans for full deployment of a truly innovative and quickly maturing version of a utility scale battery using Zinc Bromine flow technology.

My current study addresses and discusses the status of the following technical topics:

 Tank design, materials, fittings and manufacturing methods
 Stack design, materials, fittings and manufacturing methods
 Electrode design, materials, fittings and manufacturing methods
 Hydraulic system design and components
 Electrolyte formulations
 Battery Management System components and algorithms
 Systems operation (e.g. Charge/Discharge/Strip regimes)
 Thermal management
