I am always interested to hear about different battery technologies. Lithium-ion dominates of course but I certainly think there are opportunities for other chemistries and technologies to co-exist and be utilised for different applications. This is an exciting development in the flow battery space which could mean that the technology could have sufficient energy density to be used in electric vehicles. A lot of work is required to make this a viable solution to roll out at scale but one day it could compete with lithium-ion.
This also has potential not just for transport but for stationary storage applications that would have a significantly smaller footprint then current flow battery options. At Hyperion, we love working with the most innovative technology companies in the cleantech sector helping them to recruit the talent they need to achieve their growth objectives.
"Flow batteries have been around a long time, but their main problem has been a poor energy density. In other words, although you could produce a lot of power, you needed a very big tank of electrolyte to deliver it – far too big for mobile applications. "This year, my colleagues and I discovered that if we made an electrolyte out of a very high concentration of a metal oxide, it was able to absorb much more charge than we expected. The result was a flow battery with roughly ten times more energy density than had previously been achieved – 225 watt-hours per litre, with the possibility of up to 1,000 watt-hours per litre. I suddenly realised that with this energy density, application to vehicles could be possible."
