Electovaya Launces Higher Energy Density, Lower Cost "MN-Series" Li-ion Battery
Electrovaya Inc. (OTC: EFLV.PK), Toronto, Canada has launched the "MN-Series" Lithium
Ion SuperPolymer® battery technology. The MN-Series, which is a Lithiated Manganese
Oxide based system, differentiates itself from Electrovaya's Phosphate-Series solution
with up to 50% higher energy density while retaining its safety characteristics.
Their website states that their proprietary Lithium Ion SuperPolymer® batteries have an
energy density of 470-watt hours per liter, a higher energy density than other
rechargeable battery technology currently in commercial production.
This would make the the energy density of the MN-series batteries on the order of 700
Wh/liter. The higher energy density directly contributes to their batteries having
significantly longer run-times for their size (my italics) than any rechargeable
batteries currently in commercial production.
Electrovaya's proprietary Lithium Ion SuperPolymer® technology is independent of the
composition of the positive electrode active material. As such, 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. Their previous
batteries were claimed to be cost competitive with other manufacturers of lithium ion or
lithium ion polymer batteries, so we should expect some reduction in price.
Dr. Sankar DasGupta, CEO of Electrovaya, notes that "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."
The MN-Series Lithium Ion SuperPolymer® technology will complement Electrovaya's
existing roster of Phosphate-Series and (industry standard) Cobaltate-Series Lithium Ion
SuperPolymer® technology solutions.
Their lithium ion polymer technology allows them to make batteries in thin sheets that
can be stacked, folded or otherwise shaped to fit the desired form. This flexibility has
enabled them to accommodate both small size applications like tablet PC’s and larger
potential applications like electric vehicles.
Electrovaya’s zero emission vehicle, previous post, the MAYA-100 is powered by
energy-dense, lithium-ion SuperPolymer® technology. Equipped with a 35 to 50 kWh battery
pack, this long-range ZEV can travel over 200 miles between charging, at speeds up to 80
mph. In addition to the unsurpassed range, the MAYA-100 has excellent acceleration,
performance and handling.
Electrovaya has a major contract with NASA to power their Astronauts while on their
critical space walk missions. Their technology was chosen based on performance,
reliability and safety features and it’s run time. |
