Zn-Br sulfamate battery stability
On a previous post I discussed my first attempts at reproducing the Na-sulfamate based Zn-Br battery published by a group of Chinese researchers. My results showed that the chemistry works mostly as they showed, but I was unable to reproduce both the capacity and stability properties of their testing results. This post summarizes some additional research results I obtained with this chemistry and why, I believe, my results have been unable to match theirs. From the get go, my results showed […]https://chemisting.com/2026/03/23/zn-br-sulfamate-battery-stability/

Reproducing Zn-Br flow batteries using Sodium Sulfamate
A recent Chinese Nature paper showed how Sodium sulfamate can be used in Zn-Br batteries to sequester active Br2 into an N-bromosulfamate that is much less aggressive, much more water soluble and even more easily electrochemically reversible than elemental bromine. I also wrote a recent post discussing the potential use of nicotinamide to achieve this (plot twist, it doesn't work as the nicotinamide Zn complex is not very soluble). In today's post I want to share with you my attempts at […]https://chemisting.com/2026/02/20/reproducing-zn-br-flow-batteries-using-sodium-sulfamate/

Could we create a Zn-Br flow battery using Nicotinamide?
Zinc bromide flow batteries have been researched very extensively during the past 30 years. There are many advantages to this chemistry, very high potential (~1.8V), high efficiencies, symmetric electrolyte and low reagent costs. Nonetheless, the disadvantages are also huge: zinc dendrites, hydrogen evolution, bromine corrosion, etc. Despite all the development, a lot of these disadvantages remain insurmountable. A recent nature paper has disrupted the field by using sulfamate ions as a […]https://chemisting.com/2026/02/13/could-we-create-a-zn-br-flow-battery-using-nicotinamide/

Studying a WiSE based all-Fe chemistry using our flow battery kit
All-Fe flow batteries are very promising due to iron's high abundance, low toxicity and low cost. In these batteries, FeCl2 is used as the main active salt in solution. When charging Fe2+ gets reduced to Fe metal on the anode while Fe2+ gets oxidized to Fe3+ on the cathode. However, these batteries suffer from a fundamental problem that has made their large scale adoption very difficult up until now. Cyclic voltammetry of 1M FeCl2 and 4.5M CaCl2 using an Ag/AgCl reference electrode and a […]https://chemisting.com/2025/09/15/studying-an-all-fe-chemistry-using-wise-in-our-flow-battery-kit/

Working on a large scale open source flow battery design and kit
During the past couple of years we have been working on the design of a small flow battery kit for the study of flow batteries (you can read a previous post about it here). With the help of an NLNet grant, we have fully developed the first two versions of our small scale kit – with the second one achieving even longer scale tests – and are now working on the development of a larger surface area kit that can be used to study flow batteries or build flow battery applications at a relevant […]

🧵1/2 Lockheed Martin lays off 64 at their Massachusetts GridStar Flow battery plant per @bostonglobe.com
LockheedMartin also scrubbed all battery work from their website & shut down a #FlowBattery demo at Ft. Carson, CO.
No status update on a LM JV with Romania.

Long term cycling of our Flow Battery kit using a Zn-I chemistry
Our goal at the Flow Battery Research Collective (FBRC) during the past year has been to develop and manufacture a flow battery kit that can be used to study flow batteries at a small scale in a low cost yet reproducible manner. Today I want to discuss all the problems we have found when attempting long term cycling in both versions of our kit and how we have addressed them so far. Long term cycling results with the first version of our kit. Around 5 days of cycling. Our first kit design […]https://chemisting.com/2025/02/16/long-term-cycling-of-our-flow-battery-kit-using-a-zn-i-chemistry/
