Electrovaya Introduces New Lithium-Ion Battery Technology with Higher Energy Density
Submitted by reikiman on Thu, 01/18/2007 - 19:04
Electrovaya Introduces New Lithium-Ion Battery Technology with Higher Energy Density - Electrovaya Inc. has introduced its “MN-Series” Lithium Ion SuperPolymer battery technology.
The MN-Series, which is a Lithiated Manganese Oxide based system, offers up to 50% higher energy density and comparable safety characteristics to Electrovaya’s Phosphate-Series chemistry.Electrovaya’s proprietary Lithium Ion SuperPolymer technology is independent of the composition of the positive electrode active material. As such, ongoing advances in positive electrode chemistry, such as the MN-Series, are expected to enable better technical performance and safety characteristics at more economical price-points, according to the company.
The MN-Series technology will complement Electrovaya’s existing roster of Phosphate-Series and Cobaltate-Series Lithium Ion SuperPolymer technology solutions.
One of Electrovaya’s products is the Maya 100 EV. (Earlier post.) The Maya 100, which ran in the 2004 Tour de Sol and won awards for Best Battery Electric Vehicle and the Technology Award, uses either 35 kWh or 50 kWh phosphate series lithium-ion superpolymer systems.Our new MN-Series is an exciting addition to Electrovaya’s existing solution base. It is particularly well suited to large-format battery system demands with its superior energy density, power and safety characteristics and we’re pleased to offer it as part of our integrated power system solution offerings.
—Dr. Sankar DasGupta, CEO of Electrovaya
Approximate energy density of the older batteries is 225 Wh/kg and 475 Wh/liter. The new series offers density of beyond 330 Wh/kg and 650 Wh/liter.
In addition to its tablet PC and portable power business, Electrovaya is targeting the market for plug-in hybrids and zero-emission vehicles. [Green Car Congress]
