Graphene Enhances LiFePO4 Performance

[multilex]

Are there grid storage applications  utilizing graphene from NanoXplore with Hydro-Quebec  in the works?

Hydro-Quebec announced it has launched EVLO Energy Storage Inc., a subsidiary to
design, sell and operate safe, efficient and sustainable energy storage systems. These
systems would be targeting the grid storage and industrial markets and employ
LiFePO4 batteries.

Research Shows Graphene Enhances LiFePO4 Performance
Researchers at INRSEMT have shown that by adding 1% graphene to the LiFePO4 cathode
chemistry the performance of the battery can be “significantly” increased. In the
study two graphene types were used, G V4 and G V20, both supplied by
NanoXplore.

Widens NanoXplores Graphene for Use in Batteries  
While NanoXplore has mentioned the graphene polymer paste it has been developing to use in the Si anode application of Li-ion batteries, the above study shows the improvement that
graphene can offer in the cathode of LiFePO4 batteries. This potentially increases
the demand for graphene even further for the batteries of the future.



Here is the study utilizing graphene from NanoXplore:

Very interesting! NanoXplore stated that there is demand (discussion with buyers) for 120ktpa of nanoxplores graphene within 2 years. This venue could be one of the customers looking to buy, there is only one supplier that can actually deliver graphene in industrial quantities. I am really looking forward to hearing more about the customers that NanoXplore is in discussions with

Ok so now you are talking about a 2015 or 2016 R & D graphene grade (v4, v20...check on Google) which is absolutely not mentioned on the GRA corp website anylonger. Check out dont take my word for it. So 2 possibilities:: --They use an obsolete material for the sake and fun of science. I did that in my lab with plenty of materials long time ago, its nice... Or... -- it may show some results...

[j1nxed]

What do you mean by obsolete material? Why can't it just be about rebranding? They have adopted the grapheneblack (i think they have at least 3 versions of this material now) name after they realized that this was their primary market, what makes you say that v4 and v20 was produced differently than grapheneblack? I agree about external sales, but if the annual meeting is of any indication

[JimmyBly1]

Dude just compare the data sheets of both this "old" (supposedly as its not branded nor displayed on their website anylonger) and the one of this grapheneblackTM grades: the first has much more oxygen, less ashes (burning residues... they probably heat and shake the graphite) and is less pure carbon content-wise) there might be other impurities in the pie though, its a mining product

[j1nxed]

You are right that they are different, but this could be due to the fact that they have changed their process to take small flake graphite from various sources, perhaps this is what they can deliver on a very consistent basis? Another point is that they are looking to finish their pilot plant for the "battery grade" (i am not sure if this was for the graphene or the actual "paste

Here is a study where they used both heXo (M1) and Graphene Black x3 (M2) in conjunction with wood (!)

Lots of talk today about Apple building a electric car using this battery technology. (lithiun iron phosphate) Maybe why the pop today.

I think you're on to something. Apple is working on lithium iron phosphate batteries, and the following study (see link below)  said that the batteries' performance improved as a result of Graphene: The components of the battery are low cost and potentially scalable. To the best of our knowledge, complete, graphene-based, lithium ion batteries having performances comparable with
