Safety is a big advantage, but also there is the USABLE discharge cycle and recharge rate to consider.
From what I’ve read the lifepo4 battery will provide a higher voltage for longer than standard Lion batteries… So while the energy density is lower, the usable energy capacity is similar. And the option to safely quick charge (to 90% in 15 min) would make an electric car long-range road trip similar in form to a petrol powered trip…once there are metered electric charge station avalible.

I think the lithium air will make all battery obsolete if safety problem can be solved.

LiFePO4 is a very good choice for mega-producers like A123, and after they get out of their mega IP lawsuit and actually put some helpful products on the market there may be some main-stream availability of that Chemistry. It’s possible that this stuff will all just get tied up with GM, the military, and a few other players though. A good example of all these pro-cons is our decision to build our own cobalt batteries from scratch. We have a computer inside the battery itself that monitors each individual cell during charge and discharge to make sure everything is safe and controlled, and the power/weight/price ratios we get are absolutely fantastic.

Great discussion!

I have a new Miles Electric truck. My batteries don’t last long. Would you have a 12 volt battery.. 6 lifepo4

According to our experienced on usage of LiFePO4, to keep the balance of multi-cell in series is difficult. It is therefore we developed a new charge technology, different traditional charging method, incoporated with specicail designed IC to control the charge and discharge characteristics of LiFePO4 to gain both the maximum charging efficiency and the balance status.
To acheieve the goal, a new concept of charger was also designed to match with our cell’s assembly structure. Our new designed charger provides several probes, different from traditional two-probe, to adapt with different applied voltage.
By adopting this new technology, LiFePO4 battery can be run smoothly and keep balance in a good condition after long term usage.

Stop selling its advantages and tell us the truth. Im sure it is not that perfect and I have seen some of the disadvantages listed in other sites, yet there is none here.
