Battery developments

Have you noticed the recent advances in battery development. The lithium-ion and new designs for Ni-Cad are very impressive.We are on the way to quickly ramp up the hybrid and full electric vehicles. Look out gasoline price jabbers!

I heard something about a 'nano-anode' recently. Something about a manufacturing technique that makes the surface area on the anode multiply, leading to potentially huge increases in capacity in the future. But after the first blurb, I haven't seen any followups.

Unfortunately, the best battery designs are tired up in patents and the patent-holder is partly owned by Chevron, and has refused to sell many batteries.

"...The terms did not allow Matushita, Toyota, and PEVE to sell certain NiMH batteries for transportation applications in North America until the second half of 2007, and commercial quantities of certain NiMH batteries in North America until the second half of 2010..."

"...However, other actions by Cobasys suggest that the company remains unwilling to make NiMH battery technology economically feasible for the development of automobiles that rely on electric motor technology more than currently available hybrid cars. In October 2007, International Acquisitions Services, Inc., Innovative Transportation Systems AG and Neville Chamberlain filed suit against Cobasys and its parents for refusing to fill a large, previously agreed-upon order for large-format NiMH batteries to be used in the electric Innovan..."

You won't see these batteries become cheap commodity items until at least another decade, when most of these patents expire.

And one last problem is General Motor's plethora of patents that were generated during the development of the EV-1. It is speculated that the reason Toyota went hybrid, instead of

100% electric, is to dodge many of these patents.

The fact of the matter is that patent stumbling blocks are one of the hurdles to bringing a new technologically proven design to market. And the larger the demand for it, the more the patent filers and other interested parties will fight about it, and the longer the delay to market.

Sounds like you need a book on full electric vehicles.
