Hi All,
I gave a recent invited talk on Faradion's Na-ion Battery Technology at the IBA-2019 meeting in San Diego. Excellent meeting, excellent location.

Large Scale Synthesis Methods
Hi again,
While developing active materials for Li and Na-ion battery applications it is always important (imperative?) to also consider economic methods for large scale synthesis and manufacture. It is not really much use to devise new materials that are simply too expensive or too difficult to manufacture at an industrial scale. For example, some years ago we invented the Carbothermal Reduction (CTR) method for large scale synthesis of polyanion Li-ion active materials such as LiFePO4. This still remains one of the very best industry methods for this application and has been used to make many other Li-ion and Na-ion active materials.
Here is a summary of some important large scale synthesis methods I have developed:

Li and Na Active Materials Review
Hi Everyone,
Apologies for not posting for a while - but things have been very busy!
Anyway, I decided to update my active materials summary - with a table showing some of the materials I have studied, patented and commercialised for Li and Na-ion battery applications. So here goes, and I hope it is useful (table below).
In addition, the carbothermal reduction (CTR) synthesis method (see other posts in this blog; patented by JB while working at Valence Technology Inc.) remains the industry-standard manufacturing method for making e.g. LiFePO4 as well as many other Li-ion and Na-ion active materials.

Ultra Low-cost LiFePO4 Synthesis
We all understand that Li-ion batteries based on the LiFePO4 active material offer outstanding cycle life and beneficial safety properties. So what has been holding it back?
One of the major obstacles to the major commercial roll-out of LiFePO4 Li-ion batteries is the cost of the active material itself. In terms of $/kWh (i.e. the cost per energy unit) the lithium iron phosphate is relatively expensive when compared directly to traditional layered oxide materials such as LiCoO2, NCA and NMC. But why is this? Surely the nature and availability of the constituent elements would mean that LiFePO4 should be really inexpensive. That statement is basically true, but the preparation methods used commercially - often complicated and multi-step - mean that the overall manufacturing cost of the LiFePO4 is actually very high, typically around $20/kg. That's not good.
What the industry really needs is a ultra low cost manufacturing method that is easily scalable. Perhaps approaching <$10/kg. That would really make a substantial difference.
So what can one do? During the development of its proprietary Na-ion technology, Faradion Limited has also discovered some ultra low cost methods of preparation for LiFePO4 (as well as other polyanion based active materials). We anticipate that the LiFePO4 made this way will be substantially cheaper that any other currently-available commercial approach.

I'm Back!!
Hiya everyone.....my apologies for failing to update my blog regularly, but after a long delay I am back. For the last 3 years I have been working as the co-founder and CTO of Faradion Limited, a UK-based start-up company promoting a new Na-ion battery technology. As you will probably know I have been researching Na-ion technology for many years now and have maintained that this cell chemistry is the logical and sustainable replacement for Li-ion batteries in a number of low cost applications.

Faradion Limited...JB Appointed CTO
Just to let everyone know.....I was recently appointed CTO of Faradion Limited. I will take on this role while also maintaining my independent energy storage consultancy (www.jerrybarker.co.uk). Should be a busy time!!
Faradion is a high-tech start-up company based in the UK which is engaged in the development of next generation energy storage devices. The Faradion HQ is located in Sheffield, Yorkshire. The company will target the consumer, automotive and utility markets. The technical objectives will not follow the well-trodden Li-ion path, but will be investigating new, non-lithium based battery opportunities.
Additional information about Faradion may be found at the company website:
Faradion Limited website
Exciting times lie ahead for the team.

IBA - Technology Award 2012
Great News and a Big Surprise!!
The International Battery Materials Association (IBA) has decided to award me the Technology Award for 2012. Apparently the award is granted for "contributions made to identifying new secondary battery cathode materials and related materials research field, which has been recognized internationally".
Many thanks to the board of the IBA for the award ....which, as I say, was a complete surprise. The list of previous winners is extremely impressive, so I am more then happy to be included.
