Electrovaya to Provide Li-Ion Technology to Miljøbil Grenland AS
7 September 2008
Electrovaya signed a revised term sheet agreement with Miljøbil for electric car battery production in Norway whereby Electrovaya will be providing its Lithium-Ion SuperPolymer battery technology for use in a new electric car that will be marketed globally.
Electrovaya will receive equity in the automotive company, along with a license fee and a royalty fee based on the value of the battery.
Miljobil Grenland, founded in 1997, markets zero emission vehicles. It is owned by Skagerak Energi, a regional utility company, and Norsk Hydro, a $25-billion European oil, energy and light metal company, along with Vekst i Grenland and Bellona. Electrovaya has worked with Miljøbil in the past on multiple EV projects. (Earlier post.)
Tata Motors, which has said it is developing an EV based on the Indica in Norway (earlier post), is reportedly in talks with Miljøbil.
Electrovaya’s proprietary Lithium Ion SuperPolymer technology is independent of the composition of the positive electrode active material. In 2007, the company introduced its MN-Series—a Lithiated Manganese Oxide based system—which offers up to 50% higher energy density and comparable safety characteristics to Electrovaya’s Phosphate-Series chemistry.

For sure Electrovaya are producing some of most energy dense batteries around.
Polymer batteries tend to have a faster decay curve. Both timewise and cyclewise. I've looked for information on the rate of decay for Electrovaya batteries. I can't find any ... which makes me suspect they are not to keen to publicise the data.
I'm no battery chemist so it's difficult to follow the pro's and con's of the different formulae. I'm hoping the Mn series stands up better over time with a high duty cycle.
Manufacturing cost per wh for a 330 wh/kg battery has to be competetive. Should be almost 3X lower than current Li compositions. $100 per Kwh manufacturing cost is my prayer.

Plug-In-Hybrids should be built without the slightest concern for high energy batteries. They will save about as much energy without high capacity batteries as they will with them. EFFPOWER bipolar batteries can supply power bursts needed with very low technology, and Firefly foam cells can supply adequate energy for the few electric miles needed on the average. ..HG..

Listed below are links to weblogs that reference Electrovaya to Provide Li-Ion Technology to Miljøbil Grenland AS :
Electrovaya's MN Series has one of the highest energy density (up to 330 Watts/Kg) on the market.
When coupled with appropriate super-caps, it could supply all the power required for quick starts while recouperating most of the braking energy.
Electrovaya has taken one more step towards future Lithium batteries for HEVs, PHEVs and BEVs. Their next unit will have about 30% higher energy density (up to 450 Watts/Kg).
Others will certainly follow and probably do even better. The days of 500+ Watts/Kg are not that far away.
Interesting years ahead.
