IBA Meeting Photo
Hiya,
Here I am at the IBA-2019 meeting with my friends and colleagues, Christian Masquelier and Dominique Guyomard (thanks for the photo Christian!).

IBA Presentation
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.
